Mubadala Petroleum has completed drilling operations at the MNA-17 appraisal well in the Manora oilfield in the Gulf of Thailand, according to partner Tap Oil.
The Manora Oil Development joint venture was able to appraise the 500 series sands and assess a separate untested fault block, the Manora West Structure, which had the potential to de-risk the Greater Manora West prospective resources.
Tap Oil said MNA-17 was drilled to a total depth of 1916.5m. The well intersected three sands in the primary 500 sand target, the upper two were water wet with the lower sand having a log derived oil column of 2.1m
The deeper Manora West Fault block target intersected a low porosity reservoir with minor oil shows. The MNA-17well path has now been plugged and abandoned.
The MNA-17 ST1 well utilized MNA-17’s upper pilot section before being sidetracked northeast into the Central Fault Block as a new production well. MNA-17 ST1 was drilled to 1983.9m and found 17.4 m of oil pay in four separate reservoirs.
The well will be suspended prior to completion as a multi-zone production well using electric submersible pump during the upcoming hydraulic workover unit program. MNA-17 ST1 is expected to commence production in November, Tap said.
Drilling began at the beginning of the month with the Atwood Orca jackup.
Mubadala is the operator of the Manora Oil Development joint venture with 60% stake. Partners include Northern Gulf Petroleum (30%) and Tap Oil (10%).
