StatoilHydro Discovers Oil at M in the North Sea

StatoilHydro, along with its JV partners Petroro and ExxonMobil, has discovered 20-30 million recoverable barrels of oil (3-5 million Sm3 of oil) at the 25/11-25-S well in production license 169 in the North Sea.

Drilled to a depth of 1,804 meters below the sea level in 125 meters of water by the semisub Transocean Winner, the well is being permanently plugged and abandoned. The purpose of the well was to prove hydrocarbons in Paleogene reservoir rocks.

While the well was not formation tested, extensive data collection and sampling has been carried out. In a release about the discovery, StatoilHydro said, "The discovery is interesting and may, seen in the context of other discoveries in the area, have potential for further development."

Located southwest of the Grane field, production license 169 is named M prospect and was awarded in the 13th concessionary round in 1991. Well 25/11-25-S is the 13th exploration well on the production license.

Transocean Winner will move on to exploration well 25/11-25 A, a sidestep to prove hydrocarbons in a nearby prospect in the same production license. StatoilHydro serves as operator of production license 169 with 57% working interest. Petroro holds 30% interest, and ExxonMobil holds 13% in the license.
