The CGG Amadeus vessel has started a seismic acquisition programme for Singapore-based KrisEnergy in the G10/48 contract area in the Gulf of Thailand.  

The 884km² 3D acquisition programme has been awarded to CGG Services and is estimated to last 41 days.

CGG will perform the programme in north-west and south-west of Wassana sub-areas of the G10/48 licence between up to 38km from the Wassana mobile offshore production unit.

The oilfield came into production in August last year.

"The block covers 1,783km²."

Upon completion, data acquired is planned to be integrated with existing information from identified prospective areas of the G10/48 block, which also comprises the Niramai, Mayura and Rayrai oil accumulations.

The block covers 1,783km² across the Gulf of Thailand’s two discreet areas over the southern margin of the Pattani Basin in water depths of 60m.

KrisEnergy owns 89% stake in the block and also operates it, while the remaining 11% interest is owned by Palang Sophon.

The Gulf of Thailand is a core operational area for the company, which has non-operated working interests in the B8/32, B9A and G11/48 producing blocks.

In blocks G10/48 and G6/48, the company drilled four successful exploration wells last year and also submitted a plan of development for the Rossukon oilfield.

KrisEnergy also operates Block A across the maritime border in Cambodian waters.
