Reserves Update

Gulfsands Petroleum PLC 02 March 2006 2 March 2006 Gulfsands Petroleum PLC ('Gulfsands' or 'the Group') Gulfsands Announces Reserves Update O NPV of USA Proved and Probable Reserves at $193 Million O NPV of USA Possible Reserves at $24 Million O USA Exploration and Re-development Success Replaced 269% of 2005 Oil and Gas Production Gulfsands Petroleum PLC (symbol GPX), the AIM listed oil and gas exploration, development and production company with activities in the USA, Syria and Iraq, announced today that the Group's independent oil and gas engineering reserves firms have performed an updated reserves study as of 1 January 2006 for Gulfsands' Gulf of Mexico and onshore USA oil and gas properties. The proved and probable reserves for both the Gulf of Mexico and onshore USA properties are valued at $193 million. The offshore Gulf of Mexico properties represent $183 million of this total. Gulf of Mexico Reserves Gulfsands commissioned Netherland, Sewell & Associates Inc. to provide a reserves report for the offshore Gulf of Mexico properties owned by Gulfsands. The net present value of the Gulfsands proved and probable reserves in these properties as of 1 January 2006, discounted at an annual rate of 10%, is $183 million (87% of value is in proven reserves) This report shows a 42% increase in net present value from the reserves report issued on 30th June 2005. The increase in value is due to growth in proved and probable reserves through exploration and field re-development activities, as well as increased product prices. The reserves report states that Gulfsands offshore Gulf of Mexico properties contain proved and probable reserves of 32.4 billion cubic feet of natural gas equivalents (BCFGE), consisting of 19.8 billion cubic feet of natural gas (BCFG) and 2.1 million barrels of oil (MMBO). The reserves report further classified an additional 2.8 BCFGE of possible recoverable reserves, with a net present value of $15.8 million. Through ongoing exploration and field re-development activities, Gulfsands' reserves additions replaced 269% of its 2005 produced oil and gas volumes. This represents a year on year increase of 20% in Gulfsands' Gulf of Mexico reserves base. Onshore USA Reserves Gulfsands operates onshore in the USA through its 83% owned subsidiary company Darcy Energy LLC. As of 1 January 2006, Darcy Energy owned interests in two oil and gas fields onshore Texas, USA (Emily Hawes and Barb Mag). Collarini Associates has completed a reserves report on these fields. As of 1 January 2006, the net present value for the proved and probable reserves in these fields, net to Darcy Energy and discounted at an annual rate of 10%, is $9.5 million. The report states that the fields contain net proved and probable reserves of 1.6 BCFGE, consisting of 1.2 BCFG and 58,000 barrels of oil. The reserves report further classified an additional 2.2 BCFGE of possible recoverable reserves with a net present value of $7.9 million. Block 26, Syria Reserves Gulfsands announced on 30 January 2006 the results of a reserves study by Ryder Scott Company, L.P. (Ryder Scott), an independent petroleum engineering firm, on the Tigris structure. Ryder Scott developed two cases for this evaluation, an oil case and a gas case, as there was not sufficient data available at the 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). Since the issuance of this reserves report the Company has commenced further work on the Tigris structure so that Ryder Scott can be engaged for a further review of the field development plan and costs, to quantify the economic value of the Probable and Possible Reserves and Prospective Resource. Gulfsands plans to commence drilling its first well on the Tigris structure in August 2006. Gulfsands' CEO, John Dorrier, said: 'This is an outstanding result for Gulfsands' Gulf of Mexico and US onshore business operations. By adding significantly more reserves than our produced volumes in 2005 we are achieving our goal of steadily increasing the value of our US offshore and onshore assets. These volume and value increases provide solid asset backing for the Company while upside is provided by both the significant reserves and resource potential in our operated Block 26 in Syria and also the Misan Gas Project in Iraq.'

Additionally, there is a further 2.8 BCFGE of possible recoverable reserves with a net present value of $15.8 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 83% owned subsidiary company Darcy Energy LLC. As of 1 January 2006, Darcy Energy owned interests in two oil and gas fields onshore Texas, USA (Emily Hawes and Barb Mag) with proved and probable recoverable reserves of 1.6 BCFGE, consisting of 1.2 BCFG and 58,000 barrels of oil with a net present value of $9.5 million. Additionally, there is a further 2.2 BCFGE of possible recoverable reserves with a net present value of $7.9 million.
