Mubadala Petroleum, operator of the Manora oil development joint venture in the northern Gulf of Thailand, said Sept. 15 that drilling of the MNA-17 well is now completed, according to Tap Oil Ltd.
The Atwood Orca jackup drilling unit began drilling the well on Sept. 3.
The MNA-17 (AP) well path was an appraisal/pilot well, appraising the 500 Series Sands and assessing a separate untested fault block, the Manora West Structure, which had the potential to de-risk the Greater Manora West prospective resources.
The MNA-17 (AP) well was drilled to 1,916.5 m total vertical depth subsea (TVDSS). The well intersected three sands in the Primary 500 Sand target.
The upper two sands were water-wet and the lower sand had a log-derived oil column of 2.1 m TVDSS in a good porosity reservoir. The deeper Manora West Fault block target intersected a low-porosity reservoir with minor oil shows.
The MNA-17(AP) well path has now been plugged and abandoned.
The MNA-17 ST1 (AJ) well utilized the MNA-17 (AP) upper pilot section before being sidetracked to the northeast into the Central Fault Block as a new production well. The well will be suspended prior to completion as a multizone production well during the upcoming hydraulic workover unit program.
MNA-17 ST1 is expected to begin production in November.
The total well cost is expected to be US$2.5 million.
