SINGAPORE, May 27, 2025 (GLOBE NEWSWIRE) -- Valeura Energy Inc. (TSX:VLE, OTCQX:VLERF) ("Valeura" or the "Company") announces completion of an eight-well drilling campaign at Licence B5/27 (100% operated working interest), offshore Gulf of Thailand.

Sean Guest, President and CEO commented:
"Block B5/27 is a prime example of how with ongoing drilling activity we can continue to commercialise new accumulations to maintain a stable and predictable stream of cash flow from each of our Gulf of Thailand assets.  At the same time, we have appraised several additional reservoir intervals which will form the basis of a future drilling campaign on the block.  We expect to demonstrate further reserves adds at our next year-end reserves evaluation, giving rise to yet another extension in the economic life of the field."

Jasmine C
Valeura drilled two development wells from the Jasmine C platform.  Both wells were successful and exceeded management's expectation for total oil pay and are currently online as producers.

Well C-30ST1H was drilled as a horizontal lateral within the 400 sand reservoir and was completed as an oil producer.  The well's completion design includes an autonomous inflow control device, which has made it possible to complete the well as an oil producer despite being drilled into a mixed gas/oil transition zone.

Well C-39 was directionally drilled to develop three separate reservoir intervals (the 330, 160, and 50 sands), and was successful with all targets.  It was completed as a multi-zone producer, with the 330 interval now online.

Ban Yen A
The Company drilled three wells from the Ban Yen A platform.  Two were primarily development wells with additional appraisal targets, and one was a dedicated appraisal well.  The two development wells were successful, having exceeded expectations for total pay, and are online contributing to production.

Well BYA-35ST1 was drilled as a deviated multi-objective well.  The well successfully developed remaining oil volumes from multiple already-producing reservoirs, and was completed for production from a total of six sand reservoirs, which will be produced sequentially.  In addition, the well appraised several targets which will now be matured for inclusion in a future development drilling programme.  Total oil pay encountered was approximately double management's pre-drill estimates.

Well BYA-42 was drilled as a deviated well targeting remaining oil in a single reservoir interval (the 50 sands), and has been completed as a producer.  In addition, the well also successfully appraised two shallower reservoir targets, being the 480 and 260 sands, which are being evaluated as potential future infill drilling locations.
