Mubadala Petroleum has reached final total depth at two development wells at Manora Oil Field in the G1/48 concession, located in the Gulf of Thailand, and re-started drilling operations on the MNA-22 well. 

Ensco 115 (formerly Atwood Orca)

Mubadala Petroleum is the operator of the G1/48 concession and Tap Oil is its partner with a 30% interest.

The drilling program started on July 9, 2019, using the Ensco 115 jack-up drilling rig. The program entailed batch drilling of the upper hole sections of three wells followed by drilling of the reservoir sections.

In an update on Monday, Tap Oil informed that MNA-24H and MNA-23H development wells had reached final total depth and were tested with 1033 Bopd and 945 Bopd, respectively.

MNA-24H results

The MNA-24H horizontal development well was drilled from the Manora platform. The primary objective of the well was to provide a horizontal production point in the 370-10 reservoir found in the 2018 Manora-8ST appraisal well.

On July 22, 2019, at 19:15 hours (WST), the MNA-24H well reached final total depth of 2,216 meters RT. Petrophysical interpretation of well logs shows a total pay penetrated in the horizontal lateral of 155 meters with average 28% porosity. The horizontal lateral was completed with a sand screen and an electrical submersible pump (ESP).

On August 1, 2019, the MNA-24H well was tested with 1033 Bopd and 4% BSW.

MNA-23H results

The MNA-23H horizontal development well was drilled from the Manora platform. The primary objective of the MNA-23H well was to provide a horizontal production point in the 370-90 reservoir found in the 2018 Manora-8ST appraisal well.

On July 29, 2019 at 03:00 hours (WST), the MNA-23H horizontal well reached final total depth of 2,216.1 meters RT. Petrophysical interpretation of well logs show a total pay penetrated in the horizontal lateral of 197.8 meters with an average 30% porosity. The horizontal lateral was completed with a sand screen and an ESP.

On August 2, 2019, the MNA-23H well was tested with 945 Bopd and 15% BSW.

Following completion of MNA-23H well, the rig has skidded and re-started drilling operations on the MNA-22.
