PTTEP and Valeura Energy have taken a final investment decision on the first phase of the Bussabong gas field, in Block G3/65 offshore in the Gulf of Thailand. The sanctioned scope includes two gas wellhead platforms, 24 well slots apiece, with a 9-km subsea pipeline running from the new platforms to PTTEP's Central Processing Platform at the neighboring North Bongkot field in Block G2/61. A tie-back like this sends gas from new wellhead platforms into an existing processing platform rather than building a standalone one.
Project scope
The phase 1 program includes drilling 25 development wells. Valeura owns 40% of Bussabong, a stake it picked up through a completed farm-in agreement, a deal in which one company buys into another's existing license interest in a block. PTTEP holds the remaining 60% and operates the field.
Output targets
PTTEP and Valeura are aiming for first gas around year-end 2028, starting near 30 mmcf/d and climbing to 40 mmcf/d by 2030. The partners are also lining up more exploration in Block G3/65, with a well planned at the Nong Yao Northeast prospect. Thailand's regulator has signed off on a defined production area for the field, and PTTEP and Valeura expect to develop Bussabong in further phases beyond phase 1.
