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

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.

Forward-looking information in this news release includes, but is not limited to, the Manora drilling results laying the basis for further development work in the future; and management's expectation 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.

Forward-looking information is based on management's current expectations and assumptions regarding, among other things: political stability of the areas in which the Company is operating; continued safety of operations and ability to proceed in a timely manner; continued operations of and approvals forthcoming from governments and regulators in a manner consistent with past conduct; future drilling activity on the required/expected timelines; the prospectivity of the Company's lands; the continued favourable pricing and operating netbacks across its business; future production rates and associated operating netbacks and cash flow; decline rates; future sources of funding; future economic conditions; the impact of inflation of future costs; future currency exchange rates; interest rates; the ability to meet drilling deadlines and fulfil commitments under licences and leases; future commodity prices; the impact of the Russian invasion of Ukraine; royalty rates and taxes; future capital and other expenditures; the success obtained in drilling new wells and working over existing wellbores; the performance of wells and facilities; the availability of the required capital to funds its exploration, development and other operations, and the ability of the Company to meet its commitments and financial obligations; the ability of the Company to secure adequate processing, transportation, fractionation and storage capacity on acceptable terms; the capacity and reliability of facilities; the application of regulatory requirements respecting abandonment and reclamation; the recoverability of the Company's reserves and contingent resources; future growth; the sufficiency of budgeted capital expenditures in carrying out planned activities; the impact of increasing competition; the ability to efficiently integrate assets and employees acquired through acquisitions; global energy policies going forward; future debt levels; and the Company's continued ability to obtain and retain qualified staff and equipment in a timely and cost efficient manner.
