MNA-17 drilling update

Oilfield Technology,

Tap Oil has provided the following update on the Manora Oil Development in the Northern Gulf of Thailand (TAP 30% interest).

The joint venture has identified an opportunity to add further near facility production at the Manora Oil Development in 2016 through additional development drilling, and to potentially add further contingent resources via an appraisal well.


At 03:00 hrs WST on 3 September 2016 the Atwood Orca jackup drilling unit commenced drilling the MNA-17 well at the Manora Oil Development. The MNA-17 well is being drilled from the Manora platform and has both an appraisal and development component.

The MNA-17 (AP) well path is an appraisal/pilot well, appraising the 500 series sands and assessing a separate untested fault block, the Manora West Structure, which has the potential to de-risk the Greater Manora West prospective resources.


The MNA-17 (AP) well was drilled to a total depth of 1916.5 m total vertical depth subsea (TVDSS). 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 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.


The total well cost is expected to be US$2.5 million (net to Tap).

Forward plan

Drilling has now commenced on the MNA-17 (AJ) well path, which will utilise the upper pilot section before being sidetracked North-East into the Central Fault Block as a new production well. MNA-17 (AJ) is expected to increase Manora production performance. The MNA-17 (AJ) sidetrack is expected to take seven days with a total depth of 1981.2 m TVDSS.

Tap’s next expected announcement is at the completion of the drilling.
