Valeura Energy Discovers the Suraphi Field in the Gulf of Thailand

en.Wedoany.com Reported - On September 16, Valeura Energy announced the discovery of the new Suraphi field near the Manora field in Block G1/48 in the Gulf of Thailand. The discovery was made by the Manora-9 offshore exploration well and its sidetrack, located approximately 4.5 kilometers northeast of the existing Manora A platform. Valeura holds a 70% operating interest in Block G1/48 and has now moved from the exploration phase to the development planning phase, and has begun studying the construction of a new satellite production facility.

The Manora-9 well tested multiple targets located in different fault blocks. The E target encountered multiple oil-bearing intervals in the 600-series lacustrine sandstones, penetrating a total oil column of 626 feet with a net oil pay thickness of 162 feet; the adjacent D fault block encountered a total oil column of 849 feet with a net oil pay thickness of 172 feet. A third sidetrack tested a shallower, higher-risk target but did not encounter hydrocarbons.

Valeura stated that the success of the D and E fault blocks also de-risks the adjacent F fault block, which is clearly imaged on 3D seismic data. Based on pressure data acquired during drilling and structural interpretation, the company believes that multiple fault blocks may have additional hydrocarbon charge potential. Even using a conservative approach that counts only the deepest proven oil-water contact in the wells, the company still considers the discovery to have an economic basis for building a satellite development facility.

The subsequent development plan for Suraphi is intended to be integrated with the existing Manora infrastructure. Valeura plans to study the construction of a satellite platform tied back to Manora's existing wellhead and processing facilities. The company will also concurrently evaluate the Malida field, approximately 3.5 kilometers from Suraphi, to assess the feasibility of including that field in the same satellite development scheme, while re-evaluating surrounding identified exploration targets.

The existing Manora field in Block G1/48 is located in the Kra sub-basin of the Gulf of Thailand in approximately 45 meters of water depth, and Valeura holds a 70% operating interest. The Suraphi discovery is located near existing production infrastructure, so the next phase of work will focus on reservoir evaluation, development plan design, satellite facility configuration, and tie-in arrangements with Manora's existing processing system.

Meanwhile, Valeura has completed a new round of development and appraisal drilling at the Jasmine field in Block B5/27, completing a total of 4 successful wellbores, including 2 horizontal development wells and 2 directional wells with both development and appraisal objectives. Following the startup of the new wells, Jasmine field production increased from approximately 7,570 barrels per day to approximately 8,250 barrels per day, and the two multi-target wells also appraised multiple new reservoir intervals, which will continue to be studied as potential development targets.

Valeura plans to resume drilling operations in the Gulf of Thailand in early November 2026, at which time it will deploy the Shelf Drilling Enterprise rig, first implementing the drilling program at the Nong Yao field in Block G11/48, and then moving to the Wassana field in Block G10/48 for development drilling.
