CGG Services’ CGG Amadeus has started an 884 square kilometers (sq km) 3-D seismic acquisition program in the G10/48 contract area in the Gulf of Thailand, KrisEnergy Ltd. said in a news release.

The program, which is expected to last about 41 days, will be carried out in two sub-areas of the G10/48 license—northwest of Wassana and southwest of Wassana—about three to 38 km from the Wassana mobile offshore production unit, the release said.

Once complete, the seismic data will be integrated with existing data over most of the identified prospective areas of the G10/48 block, which also contains the Niramai, Mayura and Rayrai oil accumulations. The Wassana oil field came into production in August 2015.

G10/48 covers 1,783 sq km over two areas in the Gulf of Thailand across the southern margin of the Pattani Basin in water depths up to 60 meters, the release said.

KrisEnergy holds an 89% working interest and operatorship of G10/48, while Palang Sophon holds the remaining 11%.
