Final Results

Soco International PLC 09 March 2006 SOCO International plc ('SOCO' or 'the Company') Preliminary Results For The Year Ended 31 December 2005 SOCO (LSE:SIA), the international oil and gas exploration and production company, headquartered in London, traded on the London Stock Exchange and a constituent of the FTSE 250 Index, today announces its Preliminary Results for the year ended 31 December 2005. In a separate announcement today, the Company released the initial results from the first of a multiple zone test of the TGT-2X appraisal well in Vietnam, which discovered oil in the Oligocene formation with a stabilised rate of 3,300 BOPD. Additional flow tests will be conducted from Miocene intervals, one of which flowed at 9,342 BOEPD in the TGT-1X discovery well drilled last year. Operating Highlights • 85% drilling success ratio with six of seven exploration / appraisal wells drilled in 2005 successful • 75 million barrels of oil added to Group reserves in Vietnam and Yemen driven by exploration success, increasing total Group reserves threefold post Mongolia disposal • Production, net to the Company's working interest, increased to 5,684 BOPD from 5,533 BOPD the previous year • Re-structured asset portfolio to focus on high impact projects: • Disposed of interests in Mongolia for consideration of up to approximately US$93 million • Established a new core area in West Africa with the signature of a PSA for a 75% stake in Marine XI Block in Republic of Congo (Brazzaville) Financial Highlights - from continuing operations • Revenue up over 90% year-on-year to US$57.2 million (2004 : US$29.4 million) • Operating profit increased over 120% year-on-year to US$31.3 million (2004 : US$14.2 million) • Profit before tax increased over 125% to US$33.7 million (2004 : US$14.9 million) Outlook • US$100 million development and exploration programme planned for 2006 • Further exploration/appraisal drilling within Vietnam and Yemen • Progression towards Vietnam production with declaration of commerciality targeted for 1H06 • 3D seismic programme in Congo planned for second half of the year Ed Story, Chief Executive Officer, commented: '2005 was a transformative year for SOCO with exploration success generating an almost 50% growth in reserves. Strategically we re-focused our portfolio to concentrate on high impact projects; adding a new core area in Africa and disposing of our assets in Mongolia. With further exploration success announced today and a US$100 million exploration and development programme planned for the year ahead the outlook is extremely positive for continued reserve growth in 2006.' 9 March 2006 Enquiries: SOCO International plc Tel : 020 7747 2000 Roger Cagle Executive VP, Deputy CEO and Chief Financial Officer Pelham PR Tel: 020 7743 6676 James Henderson Alisdair Haythornthwaite CHAIRMAN'S AND CHIEF EXECUTIVE'S STATEMENT Simply stated, 2005 was a great year for SOCO. We had a 100% success ratio in our Basement drilling programme on Block 10 in Yemen and two wells drilled in the Cuu Long Basin in Vietnam were significant discoveries. Even the third well drilled in Vietnam, which was not classified as a discovery, came with a silver lining as it intersected oil in a previously non-productive interval on Block 9-2. This operational success has led to an impressive addition of approximately 75 million barrels of oil to the Group's net working interest proven and probable reserves in Vietnam and Yemen, resulting in an increase in total reserves of 47% over year end 2004 despite disposal of the Group's Mongolia interest. The result is not only a real numerical increase, but an overall upgrade in terms of the more immediate impact to shareholders. This momentum has carried into the first quarter of 2006 with successful tests reported in both Yemen and Vietnam. Coupled with the extraordinary drilling result, we reshaped the asset portfolio to focus on high impact, high quality projects and added capacity to our financial capability by agreeing a US$45 million reserve-based lending facility with the International Finance Corporation (IFC). The importance of having the financial strength to add valuable upside to the portfolio of a smaller company cannot be over emphasised in the current industry environment where promising projects command a high premium for entry. FINANCIAL AND OPERATING RESULTS After tax profit for the year from continuing operations more than doubled, rising to US$20.3 million from US$8.2 million in 2004. After tax profit including discontinued operations fell, reflecting the 2004 disposal of our Tunisia interests that netted US$21.4 million. The non-current portion of the consideration for the Group's disposal of its Mongolia interests in 2005 is classified as a non-current financial asset. Production net to the Company's working interest increased, rising to 5,684 barrels of oil per day (BOPD) in 2005 from 5,533 BOPD the prior year. The increase was achieved even though discontinued operations only contributed 155 BOPD during the year from Mongolia, compared to 11 months of Tunisia production (1,237 BOPD) and a full year of Mongolia production (338 BOPD) in the 2004 statistics. With full year drilling programmes in both Vietnam and Yemen, the Group had its largest capital expenditure programme ever in 2005, with a cash spend of US$76.2 million almost trebling the previous year's capital expenditures. The result is that year on year cash balances declined from US$71.1 million at year end 2004 to US$51.0 million at year end 2005. SIGNIFICANT EVENTS Consistent with the Company's stated strategy of rationalising its portfolio by monetising non-core assets, SOCO sold the entities holding its Mongolia interests to a subsidiary of PetroChina. The transaction, which closed in August 2005, immediately added approximately US$30 million to the Group's cash position with an additional US$10 million receivable placed in escrow. Subsequent compensation of up to approximately US$53 million associated with future production from the interests sold would bring the total compensation to approximately US$93 million. Importantly, this transaction allows us additional flexibility in focusing on other projects that may have a greater near term impact. The Company announced in August that its 85% owned subsidiary, SOCO Exploration and Production Congo (SOCO EPC), signed a production sharing contract with Societe Nationale des Petroles du Congo (SNPC) wherein it acquired an interest in the Marine XI Block, offshore the Republic of Congo (Brazzaville). Previous exploration on this Block led to several discoveries, one of which has been partially delineated with recoverable reserves of 20 to 60 million barrels. However, the full potential of the Block has not been previously explored as there is a thick layer of salt which has impeded seismic interpretation. Application of newer seismic technology, such as that used in Vietnam, can unlock the potential of the Block. As an exploration led company, the ability to introduce exciting new prospective areas such as Marine XI to the portfolio is key to continuing the momentum resulting from our success in Vietnam and Yemen. 2005 OPERATIONS REVIEW Vietnam It would be hard to expect a much better scenario than the one that evolved in Vietnam in 2005, but it could be just setting the stage for a better 2006. Last year got off to a resounding start with the Ca Ngu Vang (CNV) appraisal well success on Block 9-2, which tested at 13,040 barrels of oil equivalent per day (BOEPD). This success was followed by a discovery in the Tertiary sediments of a new play trend in a previously undrilled region of Block 16-1. The Te Giac Trang -1X (TGT-1X) tested at 9,432 BOEPD. TGT was the first structure tested in a new play fairway that extends for some 80 kilometres along the eastern and southern regions of Block 16-1. The second appraisal well on the CNV structure on Block 9-2 offshore Vietnam, CNV-4X, encountered an oil and gas interval with unexpected high pressure in the sandstone sequence overlying the Basement objective, and had to be temporarily suspended. The pressures encountered were significantly higher than those seen previously on the other CNV wells. The joint venture partners have redesigned the drilling plan for a re-entry into this well in 2006. Yemen The Kharir field, where the majority of the consortium's crude oil production is sourced in the East Shabwa Development Area on Block 10 in Yemen, was the focus of the Basement drilling programme for most of 2005. The consortium was rewarded with wells, which extended the limits of the field, testing at rates ranging from 7,300 BOPD from the KHA 1-10 well, testing the eastern extension of the field as then mapped, to 850 BOPD from the KHA 3- 07, which was on the previously undrilled Kharir North structure. In addition to Basement appraisal wells drilled in and around the Kharir field, the consortium initiated step-out exploration wells in the northern area of Block 10. The first of these wells, the Jathma-1 (JAT-01), tested at over 1,900 BOPD, causing considerable optimism when considering that only relatively poor quality 2D seismic data were available and the well was essentially a vertical rather than highly deviated Basement well. The consortium expects to have three rigs working on the exploration/appraisal/development/injector drilling programme in 2006. The 2005/2006 programme for Block 10 in Yemen also involves de-bottlenecking and other production enhancement efforts. The end result of this is expected to expand the consortium's export capability significantly, eventually reaching around 70,000 BOPD by 2007. CORPORATE In August 2005, SOCO agreed a credit facility with the IFC, the private sector arm of the World Bank. The US$45 million reserve-based, revolving credit facility has a seven year tenor that will be made available to SOCO in two tranches. The first tranche of US$25 million is immediately accessible and the second tranche of US$20 million is a standby loan. We are pleased to have the involvement of the IFC as they not only bring expertise in the oil and gas sector, but are also leaders on the environmental and social sustainability front. The long term availability of the financing will provide us with additional flexibility to finance our current projects and pursue future opportunities. The IFC is a strong ally in the countries in which we currently operate as well as those frontier countries in which we hope to initiate projects in the future. OUTLOOK Operationally, 2006 will be a banner year for SOCO. The capital budget will be the largest in the Group's history, with approximately US$100 million earmarked. Results from the drill bit will continue to dominate news flow in 2006. We are off to a very good start to the year in Vietnam. The first drill stem test from the TGT-2X appraisal well flowed at 3,300 BOPD from the Oligocene 'C' interval, which was non-productive in the discovery well. Testing operations continue amidst high expectations. Several analogous prospects and leads have been mapped along the fairway and we expect that the success at TGT will be repeated. As we have more successful wells on Block 16-1, we would expect the risk profile of the drilling programme to be reduced as many of the subsurface questions are answered. We expect 2006 to be a watershed year in Vietnam as we move toward development on our projects in the Cuu Long Basin. In Yemen, the exploration drilling programme, of which an extension of the Kharir field eastward will be a significant part, will give us a good indication of the upside remaining on Block 10. As importantly, the production capacity upgrades will start to have a significant impact as export capability should increase considerably throughout the year. Having established the presence of oil in the northern extension of Kharir, we will now appraise and develop the pool with inclined wells, which should yield higher flow rates such as those seen in wells in the main part of the field. There were many positives in 2005 that largely resulted from forces beyond the control of those who benefited the most. We think that external industry influences will remain fairly stable during 2006 and companies that are not positioned to create their own good fortune will be hard pressed to top last year's performance. While SOCO also benefited to a degree from environmental influences, as an exploration led company most of our success was due directly to our own efforts. More importantly, we are well positioned to continue as we have the portfolio in place and the resources to exploit it. Whilst we do not think such high drilling success ratios are sustainable in the long term, we are definitely well placed again to enjoy substantial success in 2006. We have the people, we have the portfolio and we have the materials and equipment under contract to ensure that this will again be a news driven year. Last year we spoke of streamlining our portfolio and refocusing our resources. Although the portfolio is in great shape, we would not hesitate to add additional projects that offered material upside to our shareholders. We trust that your confidence in our strategy of recognising opportunity, capturing potential and realising value will again be confirmed throughout the year. Patrick Maugein Chairman Ed Story President and Chief Executive REVIEW OF OPERATIONS The long anticipated, high impact drilling programmes in Vietnam and Yemen did not disappoint in 2005. Three wells were drilled in Vietnam, with the first two yielding spectacular results. An appraisal well to the 2002 discovery on Block 9-2 on the Ca Ngu Vang (CNV) structure tested at a daily rate of more than 13,000 barrels of oil equivalent (BOEPD). This was followed by the first exploration well to be drilled on the eastern part of Block 16-1, which tested the Te Giac Trang (TGT) structure. The TGT-1X tested at more than 9,400 BOEPD. The third well had to be temporarily suspended after encountering hydrocarbons in an unexpected high pressure environment. Results from the Yemen appraisal programme were equally impressive beginning with the 6,500 barrels of oil per day (BOPD) test on the Kharir field well KHA 1-09. This was followed by drilling successes at the KHA 2-16 (5,500 BOPD) and the KHA 1-10 well (7,300 BOPD) yielding a 100% success ratio in the Yemen drilling programme. Yemen is now the only country in which the Company has production following the 2005 disposal of its interests in Mongolia. Even with the reliance on a sole producing asset since the August disposal, crude oil production net to the Group's working interest rose from 5,533 BOPD in 2004 to 5,684 BOPD in 2005. VIETNAM SOCO holds its interests in Vietnam, all in the Cuu Long Basin offshore, through its 80% owned subsidiary SOCO Vietnam Ltd (SOCO Vietnam). SOCO Vietnam holds a 25% working interest in Block 9-2, which is operated by the Hoan Vu Joint Operating Company and a 28.5% working interest in Block 16-1, which is operated by the Hoang Long Joint Operating Company (together, JOCs). Both Blocks are on trend with several major Basement and Tertiary discoveries in the Cuu Long Basin. Both are also contiguous to the Bach Ho field, where 2005 production reportedly averaged approximately 200,000 BOPD and 200 million cubic feet of gas per day (MMCFD), and the Rang Dong field, where production reportedly averaged approximately 48,000 BOPD, primarily from Basement. Review of 2005 activities After an almost three year drilling abeyance preparing for this extensive exploration and appraisal programme, the Group resumed drilling in Vietnam with the spudding of the CNV-3X appraisal well on Block 9-2 in January. This well was drilled to a measured depth (MD) of 6,123 metres making it the longest MD well to be drilled in Vietnam. Reaching target depth on 16 April, the well had an extensive clean-up period before testing water-free at a maximum combined rate of 13,040 BOEPD comprising 9,010 BOPD and 22.6 MMCFD. Although the well was suspended as a potential producer, it will more than likely be used as an injector well following the drilling of other shallower development wells before the field goes into production. Following the CNV-3X test, the rig was towed to Block 16-1 where it spudded the initial wildcat exploration well on the 'H' prospect on 2 June. The TGT-1X was drilled to a total MD of 4,478 metres to test several Miocene and Oligocene intervals in a previously undrilled part of Block 16-1. It was drilled significantly deeper than the original prognosis due to the continuing presence of encouraging hydrocarbon shows, reaching target depth in August. A drill stem test conducted from the Lower Bach Ho formation in the Miocene interval between 2,701 metres and 2,760 metres yielded a combined maximum rate of 9,432 BOEPD comprising 8,566 BOPD of 37 degree API gravity crude and approximately 4.86 MMCFD through a 80/64 inch choke size. The calculated net pay was approximately 31 metres over the test interval. An additional 33 metres of net pay interval were not perforated due to the limited equipment and materials available within the applicable time constraints. Based on the data from the well test, oil samples from wireline formation tests and well logs, the untested interval is considered to be oil bearing and capable of production. A brief test was conducted over a deeper Oligocene interval that also contained significant oil shows, but the formation was determined to be tight and thus unable to flow commercial quantities of hydrocarbons. The rig was moved immediately back to Block 9-2 to spud the CNV-4X, a follow-up appraisal well to the CNV-3X discovery, on 31 August. The well encountered an oil and gas interval with unexpected high pressure, significantly higher than those seen previously on the other CNV wells, in the Oligocene 'E' sequence, the sandstone sequence overlying the Basement objective. The well encountered a gross 370 metre vertical section of oil shows with attendant gas through the Oligocene 'E' sandstone section, based on mud logs, drilling cuttings analysis and 'logging while drilling' logs. The use of higher than anticipated mud weights to control the encountered pressures led to problems higher in the open hole section where the drill string became differentially stuck while pulling out of the hole to run casing into the top of Basement. Numerous attempts to fish the stuck drill string were unsuccessful. In December, the well was temporarily suspended following the loss of the 121/4 inch hole section above the granitic Basement reservoir. Subsequent events and 2006 outlook An up-dip appraisal well to the 2005 discovery well on the TGT structure on Block 16-1 spudded on 18 January 2006. It reached target depth of 3,436 metres in mid-February after intersecting hydrocarbons in the Miocene and Oligocene intervals. The TGT-2X well flowed 3,300 BOPD from the first drill stem test in Oligocene 'C' interval, which failed to flow in the discovery well. At a minimum, additional flow tests will be conducted from two Miocene intervals, one which was not tested in the discovery well and the other that flowed at 9,342 BOEPD. The discovery well on the TGT structure confirmed the presence of a highly prospective Lower Miocene play fairway extending for some 80 kilometres across the southern and eastern area of Block 16-1 where several prospects and leads have been mapped. The success of the second TGT well now sets the stage to fast track the development of the field and adds significant upside to the remaining exploration potential. The Hoang Long JOC has contracted to acquire an additional 3D seismic survey in order to evaluate several leads in the area between the initial 3D survey on the western portion of the Block and the 3D survey conducted prior to exploratory operations on the eastern portion of the Block. The rig currently working is available through July to continue drilling operations in the Cuu Long Basin. It is expected that the majority of the remaining work programme for this rig will be conducted on Block 16-1. The JOCs have contracted the Transocean Triton 9 rig for a nine month period to continue drilling operations on the Blocks after the current rig contract expires, with the expectation that it will become available late in the third quarter of 2006. Efforts continue towards a declaration of commerciality for the CNV structure. The front-end work required to transition operations from the exploratory phase to the development phase has been completed. Although the timing is uncertain, the CNV-4X will be re-entered in 2006 incorporating a different drilling fluid and casing design to enable the overpressured section to be redrilled safely. YEMEN The focus on targeting Basement exploration and appraisal has completely transformed the East Shabwa Development Area (ESDA) from a rapidly declining Cretaceous producer to an asset with expectations of accelerated production through the next several years. The success here has allowed the Company to rely on this asset in the short term as its sole contributor to operating cash flow. ESDA production averaged 32,937 BOPD for 2005 increasing almost 40% from 23,635 BOPD the previous year. The Group is a 58.75% majority shareholder of Comeco Petroleum, Inc. (Comeco), which holds a 28.57% direct interest in the ESDA. A subsidiary of Occidental Petroleum, which is also a co-venturer in the ESDA with a 28.57% interest, holds the remaining interest in Comeco. Total E&P Yemen, with an interest equal to Comeco's, operates the concession and a subsidiary of Kufpec, the Kuwaiti foreign oil company, holds the remaining 14.29%. Production from the ESDA, which currently originates primarily from the Kharir field, is transported by pipeline and commingled with production from the neighbouring Masila Block before transportation by pipeline to the coastal Ash Shihr export terminal. SOCO's crude entitlement is sold under a 12-month spot market contract. Review of 2005 activities The successful drilling programme that began in 2004 featuring highly deviated wells targeting Basement continued throughout 2005. The three part programme for the year was designed to further appraise the Kharir Basement structure, to increase reserves through exploration and to increase production. The consortium enjoyed a 100% success ratio during the year. By the end of 2005, three drilling rigs were working in the ESDA. During the year, the consortium agreed a new well designation scheme proposed by the Yemeni government. Although the KHA 1-09 well (formerly KHA-403) spudded in December 2004, it wasn't tested until February 2005. The objectives of the well were to delineate the Basement and evaluate reservoir development in the undrilled western extension of the structure. The well reached a total depth of 3,383 metres and produced over 6,500 BOPD when tested. A second delineation well, the KHA 2-16 (formerly KHA-404), spudded in the northern extension of the Kharir structure on 1 February 2005 and reached a total depth of 3,539 metres. It produced more than 5,500 BOPD when tested in April. A well drilled to evaluate the eastern extension of the Kharir field spudded at the end of March. The KHA 1-10 well (formerly KHA-405) reached a total depth of 3,755 metres and was tested in June. The test was limited by capacity restrictions in the main production facility but yielded more than 7,300 BOPD. The third Basement well spudded in the 2005 ESDA drilling programme, the KHA 2-17 (formerly KHA-406), spudded on 11 June and was designed to be a water injection well for pressure maintenance of the reservoir. It was the source of a water injectivity test that began in September. The KHA 3-07 (formerly KHA-407) was the first well to target Basement on the Kharir North prospect. It spudded at the end of August and reached a total depth of 3,472 metres. The well tested in mid-November and yielded more than 850 BOPD against a 26/64 inch choke. After primarily focusing on appraisal and step-out wells in and around the Kharir field, the rig was moved to drill the Jathma exploration well (JAT-01) to test a new Basement prospect in the northern area of Block 10. The well spudded on 22 October 2005 and reached a total depth of 3,175 metres. The well tested over 1,900 BOPD against a 56/64 inch choke with an API gravity of 35 degrees. In December 2005, a second drilling rig was brought in to spud the JAT-02 well at a location in the northern part of the Jathma prospect. A third drilling rig was also commissioned during the month and on 12 December it commenced drilling a production well on the Atuf Northwest field located in the southern area of Block 10, which produces from the Cretaceous Biyad interval. During the year almost 70% of the production was sourced from the Basement although, historically, production was sourced from the Cretaceous clastic Biyad reservoir. The former has associated gas whilst the latter is characterised by high water cuts as are typical of wells producing from this reservoir in the region. Accordingly, efforts are underway to deal with declining water disposal requirements and increasing gas disposal capabilities. Work continued during the period on de-bottlenecking production facilities and increasing oil handling capacity. Subsequent events and 2006 outlook Although the JAT-02 well encountered a significant oil column, the well did not produce when production tested, which indicated poor fracture development at this location. Further evaluation of the results of this and the JAT-01 test will be carried out to establish the most appropriate scenarios for appraisal and/or development. The JAT-03 well drilled on the eastern border of Block 10 was plugged and abandoned in March after failing to encounter hydrocarbons in the Basement. Three drilling rigs are expected to continue operating throughout the year. As at the date of this publication, two rigs are drilling production and injection wells in the Kharir field. A third rig is continuing the evaluation of the Jathma/Wadi Taribah field. Additional short term production capacity was added on a temporary basis when the consortium leased a portable production unit from another area operator. This will serve to provide a production uplift whilst work continues on permanently expanding current facilities. This, together with adding water injection capability to improve pressure maintenance in the Basement reservoir, should add considerable productive capability from the interval. CONGO (Brazzaville) The Company has spent more than three years targeting areas that would allow it to focus its expertise, yet provide large enough interests and significant upside to continue its highly successful exploration led strategy. West Africa met all the criteria. As industry exploration efforts in West Africa move into ever deeper waters, the application of new technology provides access to significant reserve potential in under-explored shallow water areas. Thus negotiations began with the appropriate authorities in targeted countries several years ago to establish a foothold in the region. Marine XI was a significant first step, providing a cornerstone in the region. Review of 2005 activities The Company announced in August that its 85% owned subsidiary, SOCO Exploration and Production Congo (SOCO EPC), signed a production sharing contract with Societe Nationale des Petroles du Congo (SNPC) wherein it acquired an interest in the Marine XI Block, offshore the Republic of Congo (Brazzaville). SOCO EPC will be the operator with a 75% working interest in the Block that was licenced to SNPC by presidential decree in July 2005. The exploration and production branch of SNPC (15%) and Africa Oil & Gas Corporation (10%) hold the remaining interests. The Block, located in the Lower Congo Basin, is in shallow water adjacent to the coast with water depths ranging up to 110 metres and covers approximately 1,400 square kilometres. There has been previous exploration activity on the Block resulting in four small oil discoveries, the largest of which has initial recoverable reserves estimated to be in the 30 million barrel range. The previous discoveries are located in the shallower horizons of the sedimentary section in Marine XI. The deeper section, productive onshore and on trend to the south in Cabinda, has not been adequately evaluated as it could not be accurately mapped using older seismic data. Subsequent events and 2006 outlook The Group has issued bid documents for a 3D seismic programme which it expects to conduct in the second half of 2006. By employing the modern seismic techniques that the Company successfully applied in Vietnam to map the Basement reservoir, SOCO EPC expects to exploit the potential of the deeper section. Although the Group is in discussions with various parties to farm-out a portion of its interests in Marine XI, it would retain a significant portion of the Block and operatorship. THAILAND SOCO's 99.93% owned Thailand subsidiary holds a 100% interest in Block B8/38 located offshore in the Gulf of Thailand. The Group filed an application and development plan in 2005 with the Thailand Department of Mineral Fuels to convert the concession to a production licence on the Bualuang (renamed from Pornsiri). The application was approved in March 2006. The preferred development scenario is for the Group to farm-out a portion of its interest to a third party with expertise in development in the region. Accordingly, the Group expects to conclude discussions with various interested parties to begin development of the Bualuang field during 2006. OTHER AREAS OF INTEREST Libya The Group maintains its shareholding in the ODEX Exploration Limited (ODEX) joint venture. The ODEX shareholding comprises SOCO North Africa Ltd. (34%), and subsidiaries of Oilinvest (Netherlands) B.V. (46%) and Joint Stock Bank of the Gas Industry Gazprombank (20%). From SOCO's standpoint, the niche for ODEX was to participate with one or more indigenous Libyan companies in exploiting existing but problematic development opportunities. With the recent focus of the Libyan National Oil Company on open exploration bid rounds, significant progress in other areas is unlikely to be made in the near term. Accordingly, the Group will continue to assess its participation in the consortium in light of reasonable expectations of success. It is anticipated that ODEX will continue to be the vehicle through which the Group will explore various opportunities that may arise in Libya and certain parts of Africa as the consortium is well placed to take advantage of its strong regional relationships. West Africa The Group is interested in extending its holdings in West Africa beyond the Republic of Congo (Brazzaville) and is in various stages of negotiations with other sovereignties in the region. Under a memorandum of understanding signed with the Democratic Republic of Congo (Kinshasa), the Company carried out an initial aeromagnetic gravity survey in 2005 to further delineate prospective potential in certain areas of the country. Work continues on interpreting the results of the survey. Mongolia In April 2005, the Company entered into an agreement to sell the whole of its Mongolia interest to Daqing Oilfield Limited Company, a subsidiary of PetroChina.

General information The information for the years ended 31 December 2005 and 2004 does not constitute statutory accounts as defined in Section 240 of the Companies Act 1985 (Act). A copy of the statutory accounts for 2004 has been delivered to the Registrar of Companies and those for 2005 will be delivered following the Company's annual general meeting. The auditors' report on those accounts was unqualified and did not contain statements under Section 237(2) or (3) of the Act. Whilst the financial information included in this preliminary announcement has been computed in accordance with International Financial Reporting Standards (IFRS), this announcement does not itself contain sufficient information to comply with IFRS. The Company expects to publish full financial statements that comply with IFRS in its Annual Report and Accounts 2005. For the first time the financial statements are presented in US dollars which is the functional currency of each of the Company's subsidiary undertakings. The Directors do not recommend the payment of a dividend. This preliminary announcement was approved by the Board on 8 March 2006. 2. Basis of preparation The financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) for the first time. The same accounting policies and methods of computation are followed in the financial statements as published by the Company on 23 September 2005 in its IFRS transition document which is available on the Company's website at www.socointernational.co.uk. That document set out SOCO's comparative 2004 financial information for the year ended 31 December 2004, restated under IFRS in US dollars, including reconciliations of the income statements, balance sheets and cash flow statements between UK GAAP and IFRS. The document additionally sets out the Group's balance sheet under IFRS at the transition date of 1 January 2004, including a reconciliation to the UK GAAP balance sheet at that date. The above statements and reconciliations will be included as a note to the 2005 Annual Report and Accounts. The financial statements have also been prepared in accordance with IFRS adopted for use in the European Union and therefore comply with Article 4 of the EU IAS Regulation and with those parts of the Act applicable to companies reporting under IFRS. The financial statements have been prepared under the historical cost basis. IFRS 6 Exploration for and Evaluation of Mineral Resources has been adopted early for 2005. At the date of approval of these financial statements the Group has not applied the following IFRS and International Financial Reporting Interpretations Committee (IFRIC) interpretations which are in issue but not yet effective: • IFRS 7 Financial Instruments: Disclosures; and the related amendment to IAS 1 on capital disclosures • IFRIC 4 Determining whether an Arrangement contains a Lease • IFRIC 5 Right to Interests Arising from Decommissioning, Restoration and Environmental Rehabilitation Funds NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued) 2. Basis of preparation (continued) • IFRIC 8 Scope of IFRS 2 The adoption of these IFRS and IFRICs in future periods is not expected to have a material impact on the financial statements of the Group. 3. Segment information Geographical segments Geographical segments form the basis on which the Group reports its primary segment information.

In August 2005 the Group disposed of its Central Asia segment which comprised its Mongolia interest (see Note 5). The results of these segments are therefore included in discontinued operations. Business segment The Group has one principal business activity being oil and gas exploration and production. Revenue by destination does not materially differ from revenue by origin. There are no inter-segment sales. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued) 4.

Taxation in other jurisdictions is calculated at the rates prevailing in the respective jurisdictions. During 2004 and 2005 both current and deferred taxation have arisen in overseas jurisdictions only. The charge for the year can be reconciled to the profit per the income statement as follows: 2005 2004 $000s $000s Profit before tax on continuing operations 33,662 14,887 Profit before tax on discontinued operations 181 24,868 _______ _______ 33,843 39,755 Profit before tax multiplied by standard rate of corporation 10,153 11,927 tax in the UK of 30% (2004 - 30%) Effects of: Expenses not expected to be utilised as a tax loss 1,423 1,186 Non taxable profit on disposal (58) (4,758) Utilisation of tax credits - (205) Higher tax rates on overseas earnings 1,906 2,469 Adjustments to tax charge in respect of previous years (58) (435) _______ _______ Tax charge for the year 13,366 10,184 The tax charge in future periods may also be affected by these factors. The Group's overseas tax rates are higher than those in the UK, primarily because the profits earned in Yemen are taxed at a rate of 35% and those earned in Tunisia were taxed at a rate of 50%. 5. Disposal of Mongolia In April 2005 the Group entered into a Sale and Purchase Agreement (Agreement) with an economic effective date of 1 January 2005, to sell its 100% owned subsidiaries SOCO Tamtsag Mongolia, LLC (SOTAMO) and SOCO Mongolia Ltd (SOCO Mongolia) to Daqing Oilfield Limited Company (Daqing), a subsidiary of PetroChina. Together SOTAMO and SOCO Mongolia held the Group's Mongolia interest. In August 2005 the Group completed the transaction. Under the terms of the Agreement the Group will receive consideration of up to approximately US$93.0 million comprised of cash consideration of US$40.0 million plus a subsequent payment based on total crude oil produced from the Mongolia interest after the effective date in excess of 27.8 million barrels of oil. The US$40.0 million cash consideration was payable in two tranches. The first US$30.0 million was paid, less applicable settlement adjustments of US$0.4 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (continued) 5. Disposal of Mongolia (continued) million, in August 2005 upon completion. The second tranche of US$10.0 million was paid into an interest bearing escrow account by Daqing upon completion to be released to the Group 18 months later upon the satisfaction of the condition that no material undisclosed additional liabilities are discovered and is disclosed in the balance sheet under non-current assets as an other receivable. The remaining consideration is payable, once cumulative production reaches 27.8 million barrels of oil as described above, at the rate of 20% of the average monthly posted marker price for Daqing crude multiplied by the aggregate production for that month, up to a total of approximately US$53.0 million based on the estimated recoverable costs incurred to 31 December 2004, as approved by the Mineral Resources and Petroleum Authority of Mongolia. The subsequent payment amount is included in non-current assets as a financial asset at fair value through profit or loss. The timescale for the production of crude oil in excess of 27.8 million barrels and the price of Daqing marker crude oil are factors that cannot accurately be predicted. However, based upon the Directors' current estimates of proven and probable reserves from the Mongolia interests and the development scenarios as discussed with the buyer, the Directors believe that the full subsequent payment amount will be payable. The fair value of the subsequent payment amount was determined using a valuation technique as there is no active market against which direct comparisons can be made. Assumptions made in calculating the fair value include the factors mentioned above, risked as appropriate, with the resultant cash flows discounted at a commercial risk free interest rate. The fair value of the financial asset at the date of completion of the sale was US$31.5 million. As at 31 December 2005 the fair value was US$31.9 million after accounting for the unwinding of the discount. As the Group's Mongolia asset is now classed as a discontinued operation the revenue and cost of sales have been removed from continuing operations. There is no impact on operating profit as revenue arose from test production during an appraisal programme and an amount was charged from appraisal costs to cost of sales so as to reflect a zero net margin. Revenue attributable to the Mongolia interest up to the date of completion was US$1.5 million (2004 - US$3.2 million). Immediately prior to the sale the Group's share of net assets held by the Mongolia interest was US$68.8 million (2004 - US$65.4 million) comprising intangible assets of US$71.0 million (2004 - US$71.6 million), current assets of US$ nil (2004 - US$0.7 million), current liabilities of US$0.4 million (2004 - US$5.2 million) and long-term provisions of US$1.8 million (2004 - US$1.7 million). Immediately after the completion of the sale the Group recognised cash inflow of US$29.6 million, other receivables of US$10.0 million, a gain of US$0.2 million based on the fair value of the financial asset of US$31.5 million (see above) and transaction costs of US$2.1 million.
