Valeura Energy Inc. has completed an infill drilling campaign at the Manora field in the Gulf of Thailand, where the company holds a 70 percent operated working interest in Block G1/48.
The campaign, drilled from the Manora A platform, included two infill development targets and one appraisal well. All three wells were successful. The appraisal well was also 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 oil production increased from an average of 1,950 bbls/d before the first new well came on stream to a more recent average of 2,626 bbls/d on a working interest basis before royalties.
The MNA-41 well 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 that zone. It also encountered five oil pay zones in the 400/500-series reservoir. The well has been completed as a commingled oil producer and is now on production.
The MNA-35ST1 well was drilled as a sidetrack to the existing MNA-35 well to develop the same two reservoir intervals accessed in MNA-41. Two pay zones were encountered in the 300 sands and will be completed for production in the future. The well has been completed as a producer from five oil pay zones in the 400/500 reservoir sands and is now on production.
The MNA-42H well was geo-steered as a horizontal development well within the 300-series sand reservoir. Its 1,046 ft lateral section encountered 556 ft of net oil pay. The well has been completed and is now online as a horizontal oil producer.
According to Valeura Energy Inc., the Manora drilling campaign was completed safely, on time and on budget.
Following the Manora program, the contracted drilling rig has been mobilised to the Nong Yao field in Block G11/48, where Valeura Energy Inc. holds a 90 percent operated working interest. The company plans a production-oriented drilling campaign from the Nong Yao A and Nong Yao B wellhead facilities.
