Mubadala wraps up Manora drilling

  • Exploration & Production

Mubadala Petroleum has completed drilling of the MNA-17 well on the Manora Oil Development located in the Northern Gulf of Thailand. The new production well is set to come online in November. 

Mubadala Petroleum is the operator of the G1/48 concession containing the Manora Oil Development with 60% interest, and its partners are Tap Oil with 30%, and Northern Gulf Petroleum with 10% interest.

The Joint Venture 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.

To remind, the Atwood Orca jack-up drilling unit started drilling the MNA-17 well at the Manora Oil Development on September 3, 2016. The MNA-17 well was being drilled from the Manora platform and had both an appraisal and development component.

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 a total depth of 1916.5 meters 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 MNA-17 ST1 (AJ) well, utilized the MNA-17 (AP) upper pilot section before being sidetracked North-East into the Central Fault Block as a new production well.

MNA-17 ST1 (AJ) was drilled to a total depth of 1983.9 meters TVDSS and found 17.4 m of oil pay in 4 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 start production in November. The total well cost is expected to be $2.5 million (net to Tap) location.
