Valeura Energy Inc. Announces Manora Drilling Exceeds Management's Expectations

CALGARY, AB / ACCESS Newswire / March 9, 2026 / Valeura Energy Inc. (TSX:VLE,OTC:VLERF)(OTCQX:VLERF) ("Valeura" or the "Company") announces completion of a successful infill drilling campaign at its Gulf of Thailand Manora field (Block G1/48, 70% operated working interest).

Dr. Sean Guest, President and CEO commented:
"Our Manora drilling campaign illustrates that we can continue adding to the ultimate production potential of our Gulf of Thailand fields. Our approach is to take every opportunity to appraise potential future development locations while developing known reservoir intervals. We have once again delivered new production from the field and also laid the basis for further development in the future."

Valeura successfully drilled a campaign comprised of two infill development targets and one appraisal well from the Manora A platform. All wells were successful, and notably the appraisal well was found to be optimally positioned for use as a production well. As a result, all three wells have been completed as oil producers and are now on stream. Manora's oil production has increased from an average of 1,950 bbls/d prior to the first new well coming onstream, to a more recent average of 2,626 bbls/d (working interest share oil production before royalites)⁽¹⁾.

Valeura's management expects that the newly encountered reservoir intervals will be considered in the next evaluation of reserves and could therefore be additive to the ultimate potential and economic life of the asset.

MNA-41 was drilled as a deviated appraisal well to evaluate the potential of two reservoir intervals. The well encountered oil pay in the 300-series sand reservoir, which will be analysed to identify future prospects in this zone. In addition, the well encountered five oil pay zones in the 400/500-series reservoir. It has been completed as a comingled oil producer and is now on production. Results have exceeded management's expectations, which sought only to assess the potential for future development of these intervals.

MNA-35ST1 was drilled as a sidetrack to the pre-exisitng MNA-35 well, with the objective of developing the same two reservoir intervals access in MNA-41. Two pay zones were encountered in the 300 sands, which will be completed for production in the future. In the meantime, the well has been completed as a producer of five oil pay zones within the 400/500 reservoir sands and is now on production.

MNA-42H was geo-steered as a horizontal development well within the 300 series sand reservoir. The well's 1,046 ft lateral section encountered 556' of net oil pay, which has exceeded management's expectations. The well has been completed and is now online as a horizontal oil producer.

The Manora drilling campaign was completed safely, on time, and on budget. Valeura's contracted drilling rig has now been mobilised to the Nong Yao field on block G11/48 (90% operated working interest) where the Company is planning to drill a production-oriented campaign from the Nong Yao A and Nong Yao B wellhead facilities.
