Valeura Energy completed its drilling campaign at the Nong Yao field in the Gulf of Thailand, incorporating a multilateral well architecture for the first time as part of its strategy to optimize offshore reservoirs development.
Nong Yao: Well performance and production increase
During the program, the company drilled eight wells in Block G11/48, where it holds a 90% operated working interest. The scope included one appraisal well and seven horizontal development wells drilled from the Nong Yao A and B platforms.
All wells met their geological targets and entered production. Likewise, the NYA-42ST1H well set a regional record with a 4,960-ft horizontal length, maximizing reservoir contact.
Field production increased from 8,870 to approximately 10,500 barrels per day, driven by the new wells and by workover operations carried out in parallel on the Nong Yao B and C platforms.
Valeura’s first multilateral well
The most significant technical development was the drilling of the NYB-02ST1 well, designed under a multilateral scheme with a complex junction point.
This design enabled two independent horizontal laterals to be drilled from a single main wellbore, each targeting different reservoir intervals. As a result, Valeura can produce from multiple zones using a single surface infrastructure.
Likewise, this technique improves operational efficiency by reducing new drilling locations, optimizing platform use, and expanding access to productive areas of the reservoir.
Next phase at the Jasmine field
Valeura is assessing the application of this technology in other fields in the Gulf of Thailand, especially in reservoirs where the geometry and distribution of productive intervals favor multilateral configurations.
The drilling rig has already been mobilized to the Jasmine field in Block B5/27, where the company plans to carry out a new five-well program, including another multilateral development.
With this campaign, Valeura strengthens its growth strategy in Southeast Asia through offshore drilling, optimization of producing assets, and technologies aimed at improving oil recovery.
