Reserves Report

Gulfsands Petroleum PLC 30 January 2006 30 January 2006 Gulfsands Petroleum PLC ('Gulfsands' or 'the Group') Gulfsands Announces Reserves Report for Tigris Structure on Block 26, Syria Gulfsands Petroleum PLC (symbol GPX), the AIM listed oil and gas exploration, development and production company with activities in the USA, Syria and Iraq, is pleased to announce that an independent reserves study has been completed by Ryder Scott Company, L.P. on the Tigris structure in Block 26, Syria. Highlights As the operator and having a 50% working interest in Block 26, Syria, Gulfsands engaged Ryder Scott Company, L.P. (Ryder Scott), an independent petroleum engineering firm, to conduct a reserves study based on the results of a well drilled on the Tigris structure in 1994 and 3D seismic data over the structure. Ryder Scott developed two cases for this evaluation, an oil case and a gas case, as there is not sufficient data available at this time to determine the expected hydrocarbon fluid contained within the Tigris structure. This reserves study as of 1 January 2006 classified recoverable Probable and Possible Reserves and Prospective Resource as follows: • For primarily a natural gas accumulation, Ryder Scott has classified 442 BCFG as Probable Reserves, 442 BCFG as Possible Reserves, and a further 3447 BCFG as a Prospective Resource. In summary total reserves potential among Probable, Possible and Prospective Resource is 4330 BCFG (722 MMBOE). • For primarily an oil accumulation, Ryder Scott has classified 104 million barrels of oil and 64 BCFG as Possible Reserves and a further 408 MMBO and 245 BCFG as a Prospective Resource. In summary total reserves potential among Possible and Prospective Resource is 512 MMBO and 308 BCFG (combined 563 MMBOE). The study identified nine potentially productive zones within Palaeozoic age reservoirs in the existing well bore. Gulfsands has signed a Letter of Intent with a drilling contractor to drill a well on the Tigris structure. Gulfsands plans to commence drilling this well in August 2006. Block 26 Reserves Subsequent to increasing Gulfsands' working interest to 50% and becoming the operator of Block 26, the Group conducted a detailed review of the six wells previously drilled to test Palaeozoic reservoirs within the Block. From this work, Gulfsands concluded that three of the wells encountered potentially commercial hydrocarbon accumulations, based on drilling and independent wireline log evaluation. The largest of these probable accumulations, the Tigris structure, is found beneath the Souedieh Field, the largest oil field in Syria with estimated reserves of some 2 billion barrels of oil recoverable (approximately 1.3 billion barrels of oil produced to date). Gulfsands' Production Sharing Contract in Block 26 includes oil and gas rights to Palaeozoic age reservoirs beneath all of the existing fields within Block 26, such as the Tigris structure, and oil and gas rights to all depths in areas outside of the existing producing fields. Gulfsands engaged Ryder Scott to prepare an independent reserves study of the Tigris structure to quantify and classify reserves conforming to the definition approved by the Society of Petroleum Engineers and the World Petroleum Congress. The data used for the study includes wireline logs from a well drilled to the Palaeozoic in the Tigris structure in 1994, and a 3D seismic survey available over the Souedieh Field. Ryder Scott developed two cases for this evaluation, an oil case and a gas case, as there is not sufficient data available at this time to determine the expected hydrocarbon fluid contained within the Tigris structure. Reserves and resource figures in this announcement are stated in BCFG (billions of cubic feet of natural gas), MMBO (millions of barrels of oil) or MMBOE (millions of barrels of oil equivalent, where six thousand cubic feet of natural gas is equivalent to one barrel of oil). The Tigris structure is of a significant size, potentially as large as some 75 square kilometres, and only one well bore currently exists on the structure. It is difficult to assess the full reserve potential within Proved, Probable and Possible Reserves at this time. However, based on the data that are currently available, the Ryder Scott report concludes that there are nine potentially productive zones contained within Palaeozoic age reservoirs found in the existing well bore on the Tigris structure. The report classifies 883 BCFG as Probable and Possible Reserves if the Tigris structure is primarily a natural gas accumulation. The report classifies 104 MMBO and 64 BCFG as Possible Reserves in these zones if the Tigris structure is primarily an oil accumulation. The report further classifies an additional 3447 BCFG as an unrisked Prospective Resource within the gas case or 408 MMBO and 245 BCFG as an unrisked Prospective Resource in the oil case. The Prospective Resource was based on potential resources below the base of the hydrocarbon bearing zones encountered in the existing well bore, as a definitive water contact is not identified with the existing data. In summary, the natural gas case equates to total reserves potential among Probable, Possible and Prospective Resource as 4330 BCFG (722 MMBOE), while the oil case equates to 512 MMBO and 308 BCFG (combined 563 MMBOE). Gulfsands' 50% working interest in Block 26 and the Tigris reserves are subject to the fiscal terms of this Production Sharing Contract. Following this initial review, Ryder Scott will undertake a further review of the field development plan and costs, to quantify the economic value of the Probable and Possible Reserves and Prospective Resource. John Dorrier, CEO of Gulfsands Petroleum, said: 'This independent study confirms our conclusion that Block 26 contains probable pay in Palaeozoic reservoirs and significantly increases the Company's overall reserves. The report further demonstrates the lower risk associated with finding large oil and gas reserves in Block 26 and increases the total Block potential significantly.'

Additionally, there is a further 3.4 BCFGE of possible recoverable reserves with a net present value of approximately $14 million. • Syria In Syria, Gulfsands owns a 50% working interest in Block 26 and is the operator. The block covers 11,000 square kilometres and surrounds areas which currently produce over 100,000 barrels of oil per day from existing fields. In January 2006 the Group completed the acquisition of 1,155 kilometers of 2D seismic and anticipates drilling two wells during 2006. The first well, known as Souedieh North is scheduled to be drilled in May of 2006 which has the potential to contain in excess of 100 MMBO. The second well known as Tigris is scheduled to be drilled in August of 2006 and has the potential to contain in excess of 500 MMBOE. Gulfsands has identified 31 total exploitation and exploration prospects within Block 26 with mean resources potential exceeding 1 billion barrels of recoverable oil. An independent reserves report was issued in January 2006 on the Tigris structure. The reserves were classified as either oil or gas bearing until such time as the Company drills and tests the Tigris structure. The reserve report concluded that there are 442 BCFG of probable recoverable reserves in the Tigris structure. Additionally, the report classified the possible reserves as either natural gas or oil. The gas case reflected an additional 442 BCFG in possible recoverable reserves and an additional 3447 BCFG as prospective resource. The oil case reflects 104 MMBO and 64 BCFG in possible recoverable reserves and a further 408 MMBO and 245 BCFG as prospective resource. In summary, the natural gas case equates to total recoverable reserves potential among probable reserves, possible reserves and prospective resource as 4330 BCFG (722 MMBOE), while the oil case equates to 512 MMBO and 308 BCFG (combined 563 MMBOE). • Iraq Gulfsands signed a Memorandum of Understanding in January 2005 with the Ministry of Oil in Iraq for the Misan Gas Project in Southern Iraq and is currently negotiating the definitive contract for the project. The project will gather, process and transmit natural gas that is currently a waste by-product of oil production in the region and will end the environmentally damaging practice of gas flaring. Gulfsands has completed a feasibility study and expects to conduct further technical work and commercial discussions with the Iraq Oil Ministry. • Onshore USA Gulfsands operates onshore in the USA through its 80% owned subsidiary company Darcy Energy LLC. At the Emily Hawes field, initial gas production commenced in the summer of 2005. The first well in the Barb Mag oil field has been drilled and wireline logged with some 38 feet of potential net pay and production tested at 1.5 million cubic feet of natural gas and 36 barrels of condensate per day. Production from this well should commence during the first quarter of 2006. Darcy Energy has a 34.375% and 37.5% working interest in these fields respectively.
