ASX-listed Tap Oil Limited reports that the MNA-17 ST1 development well is expected to commence production in the Northern Gulf of Thailand in November.

Drilled as part of the Manora Oil Development, the MNA-17 ST1 (AJ) well, utilised the MNA-17 (AP) upper pilot section before being sidetracked north-east into the Central Fault Block as a new production well.

The well was drilled to a total depth of 1983.9 metres TVDSS and found 17.4 m of oil pay in four separate reservoirs and has been suspended prior to completion as a multi zone production well using electric submersible pump during the upcoming hydraulic workover unit program.

The Manora Oil Development JV’s news on the the MNA-17 (AP) well was not as positive.

Drilled by the Atwood Orca jackup drilling rig, 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 well was drilled to a total depth of 1916.5 metres total vertical depth subsea (TVDSS), intersecting well intersected three sands in the Primary 500 sand target. However, the upper two sands were water wet with the lower sand having a log derived oil column of 2.1m TVDSS in 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.
