Canada-based oil and gas company Valeura Energy has successfully concluded its infill drilling campaign at the Jasmine field in the Gulf of Thailand. This effort resulted in a 26% increase in production, bringing five new wells into operation.
The programme involved two development wells on the Jasmine A platform, completed earlier in September 2024, and three additional development wells on the Jasmine D platform. All five wells have been brought online as producers. The recent Jasmine D wells also appraised several new reservoir intervals, showcasing the potential for further resource development.
One notable well, JSD-42, targeted the 250 sand reservoir and was optimally positioned at the crest of the structure. It has been completed and is now producing oil as anticipated. This well also evaluated five secondary zones that were completed for future production and identified several additional oil-bearing intervals that could be pursued in the future.
The other two wells, JSD-41H and JSD-43H, were drilled as horizontal infills in the 680-1 sand reservoir. These were designed to maximise oil recovery from this productive zone. Both wells, which had horizontal sections exceeding 2,000 feet, successfully encountered continuous net sand.
With these new wells now operational, production at Jasmine has reached an average of 9,801 barrels per day (bbls/d) before royalties, measured over a seven-day period in late November 2024. This marks a significant increase compared to the 7,764 bbls/d recorded in early September, before the new wells were introduced.
Following the completion of the Jasmine D drilling programme, the contracted rig has been relocated to the Manora field under Licence G1/48, where Valeura holds a 70% working interest. Here, the company has commenced a new five-well campaign comprising both production and appraisal drilling.
Sean Guest, President and CEO of Valeura, expressed satisfaction with the results, highlighting the improved production rates of nearly 10,000 bbls/d. He emphasised the importance of sustaining production to maintain cashflow and noted the encouraging appraisal results at the mature Jasmine field. These achievements are expected to play a critical role in the company’s year-end reserves assessment and contribute to its goal of achieving over 100% reserves replacement.
Valeura Energy’s focused drilling efforts at the Jasmine field have significantly enhanced production while opening new opportunities for future development. These successes demonstrate the company’s ability to optimise its assets and sustain long-term value.
