The Mubadala Petroleum-operated Sri Trang-1 exploration well in the Gulf of Thailand has confirmed the presence of oil in the Reservation Area of the G1/48 concession, according to its partner Tap Oil Ltd.

Test results confirmed the presence of oil in poor quality reservoir sand, and samples collected from three other zones confirmed the presence of water, a news release said. Although the oil is not in commercial quantities, the Sri Trang-1 discovery has validated the hydrocarbon prospectivity of the Northern Kra Basin, Tap Oil said in the release.

The well is located in the Gulf of Thailand about 18 km north northeast of the Manora oil development.

The well was spudded May 17 in 40 m of water by the Atwood Orca jackup drilling unit and was drilled to an extended final total depth of 2,814 m measured depth. The rig has now been moved off location, the release said.
