Valeura Energy has wrapped up a drilling phase focused on field development on its Gulf of Thailand portfolio and is preparing a larger 2026 well program that combines development work with reservoir appraisal across its Thai fields.
In 2026, the company plans to drill 16 wells, a mix of development and appraisal wells, across the fields it operates in Thailand. The campaign is structured to support ongoing production and to refine its understanding of the reservoirs by steering selected development wells through zones earmarked for appraisal.
The new plan follows a Q4 2025 campaign on Block B5/27, where the company drilled nine new development wells and brought each into production. That work included horizontal wells with long step-outs, one of which set a new internal record for horizontal reach in its Gulf of Thailand operations. While drilling those wells, the company also steered through additional appraisal objectives and confirmed extra oil volumes that may be used as candidates for future infill wells.
To support the work, Valeura has a single drilling rig contracted until August 2026. The unit will move between several fields under a combined schedule covering the company’s Thai assets.
In parallel, project planning and engineering for a redevelopment of the Wassana field are progressing, with preparations aimed at a possible new phase of drilling on the redeveloped field from early 2027.
