Drilling Report

Gulfsands Petroleum PLC 11 September 2006 11 September 2006 Gulfsands Petroleum plc ('Gulfsands' or 'the Company') Tigris-1 Well Commences in 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 the Company has commenced drilling the Tigris-1 well within Block 26, Syria. The Tigris-1 represents the first of a series of wells proposed to be drilled by the Company in Block 26 over the next 12 months. Gulfsands is currently in final negotiations on an additional drilling rig to be utilized within Block 26 for this continuous drilling program. Gulfsands, the operator and 50% working interest owner in Block 26, has commenced the drilling of the Tigris-1 confirmation well located in the northeast region of Block 26. This vertical well will be drilled to an approximate depth of 4,500 meters with the primary objective being Carboniferous and Devonian aged reservoirs directly underlying the Souedieh Oil Field, the largest known oil field in Syria. This well is scheduled to take 90 to 120 days to drill and evaluate at an estimated cost of $7.3 million, or $3.65 million net to Gulfsands. The Tigris-1 well will be the second well to target the Carboniferous and Devonian aged reservoirs within the overall Tigris structure. The S1100 well, drilled in 1994 by the Syrian Petroleum Company and located approximately 1 kilometre northeast of the Tigris-1 well, was the first well to intersect these reservoirs within this structure. Independent interpretation of the wireline logs from the S1100 well indicates a substantial hydrocarbon column. The main objective of the Tigirs-1 well is to confirm the presence of this hydrocarbon column. Tigris has been estimated by Ryder Scott Company, L.P. to have 442 BCFG of gross probable reserves with a net present value discounted at 10% of $233 million net to Gulfsands 50% working interest. Ryder Scott has estimated the gross prospective resource size for Tigris as some 4.3 TCF of natural gas, or 562 million barrels of oil. The Ryder Scott reserve reports can be viewed on Gulfsands' website at www.gulfsands.net. Gulfsands' CEO, John Dorrier, said: 'The drilling program being undertaken in Block 26 holds great potential for the Company. The Tigris well is the first in a series of wells planned to be drilled on a near continuous basis over the next 12 months on the Block. The Block 26 drilling program, in combination with the Company's development work on the Misan Project in Iraq and the oil and gas production oriented programs in the Gulf of Mexico uniquely position the Company for asset growth.'

Note to Editors • Gulf of Mexico, USA The Company owns interests in 64 offshore blocks comprising approximately 216,000 gross acres which includes 39 producing oil and gas fields offshore Texas and Louisiana with proved and probable recoverable reserves of 32.4 BCFGE, consisting of 19.8 BCFG and 2.1 MMBO as of 1 January 2006 with a net present value of $183 million. 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 Company completed the acquisition of 1,155 kilometres of 2D seismic and anticipates drilling two wells during 2006. The first well, known as Souedieh North, commenced drilling in late April 2006 and was temporarily suspended in June for further analysis. The second well known as Tigris commenced drilling in September 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. Ryder Scott completed a reserves study on the Tigris structure in 2006 and these reserves were classified as either oil or gas bearing until such time as the Company drills and tests the Tigris structure. As of 1 July 2006 Ryder Scott determined that the Probable Reserves net to Gulfsands after applying the terms of the Production Sharing Contract is 102 BCFG with a net present value discounted at 10% of $233 million. For primarily a natural gas accumulation, an additional 75 BCFG of possible reserves net to Gulfsands were estimated to have a 10% discounted net present value of $261 million. Furthermore, the Company completed its own economic evaluation on the Prospective Gas Resource and has estimated that Prospective Gas Resource net to Gulfsands is 577 BCFG with a net present value of approximately $1.06 billion. In summary total gas reserves potential net to Gulfsands among Probable and Possible Reserves for the natural gas case is 177 BCFG (30 MMBOE) with a net present value of $494 million and when combined with the Prospective Gas Resource it totals 754 BCFG (126 MMBOE) with a net present value of approximately $1.55 billion. For primarily an oil accumulation, Ryder Scott determined the Possible Reserves net to Gulfsands after applying the terms of the Production Sharing Contract are 19.4 million barrels of oil having a net present value discounted at 10% of $452 million. Furthermore, the Company completed its own economic evaluation on the Prospective Oil Resource and has estimated that Prospective Oil Resource net to Gulfsands is 50.9 MMBO with a net present value of approximately $1.51 billion. In summary total oil reserves potential net to Gulfsands among Possible and Prospective Oil Resource for the oil case is 70.3 MMBO with a net present value of approximately $1.96 billion. • 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.
