Start-up Year: -

Tasour field is located in the Masila Basin, block 32 in Yemen. DNO took over Block 32 in 1998 from Clyde Petroleum and Norsk Hydro; both of who had already found oil in the Tasour-1 well. At the time, the assumption was that the Tasour reservoir contained approximately 5 million barrels of oil, but analyses performed by DNO suggested that it was almost twice as large. The distorted seismic images caused by large faults and very rough surface topology above the reservoir explains the low reserve estimates in the early phase. DNO concluded that even a small discovery could be developed economically, and production started in November 2000. A major breakthrough was the drilling of Tasour-7 in 2002. This well almost tripled the ultimate reserve estimate to 20 million barrels. Per 31 December 2011 DNO has produced 36.8 million barrels and the ultimate reserves estimate is more than 40 million barrels. The remaining gross reserves are estimated at 2.0 million barrels of oil. Tasour reached plateau production level of 17-20,000 barrels per day in 2003-2004, and 26 wells have been drilled so far in order to maximise the reserves. TransGlobe holds 13.8% working interest in Block 32. Block 32 is operated by DNO ASA with 38.95% interest.
