Canadian company Valeura Energy Inc. has completed an eight-well drilling campaign on its 100%-operated offshore Block B5/27 in the Gulf of Thailand. The operation, conducted safely and under budget, aimed to reinforce production stability and prepare for future investment in exploration and development.

Positive outcomes on Jasmine and Ban Yen platforms

Two wells were drilled from the Jasmine C platform. The horizontal well C-30ST1H was completed as a producer in a gas/oil transition zone using an autonomous inflow control device. Directional well C-39 targeted three distinct reservoirs. The 330 reservoir is already online and contributing to production.

Three additional wells were drilled from the Ban Yen A platform. Well BYA-35ST1 was completed across six consecutive reservoirs, with oil volumes in place estimated to be about twice pre-drill expectations. Well BYA-42, targeting a single reservoir, also appraised two additional targets for future drilling. The appraisal well BYA-41 encountered a smaller-than-expected oil accumulation and was not completed for production.

Extended potential on Jasmine D, limited results on Ratree

On the Jasmine D platform, wells D-44 and D-45 reached all primary and secondary targets. The first confirmed the potential of five additional reservoirs within a fault block, while the second identified a new target to be developed in a future phase.

In contrast, the exploration well drilled at the Ratree area encountered only trace hydrocarbons due to a lack of effective oil migration into the structure. Valeura plans to continue evaluating other prospective trends on Block B5/27.

Following the campaign, the company maintained a stable production level compared to the first quarter. The contracted drilling rig has now been redeployed to the Nong Yao field, where Valeura plans to invest in a drilling programme of approximately ten additional wells over the coming months.
