Mubadala wraps up Manora development drilling

Mubadala Petroleum has completed a three-well development drilling program at its Manora field in the Gulf of Thailand.

The program started when the first well was spudded on July 9, 2019, using the Ensco 115 jack-up drilling rig. It entailed batch drilling of the top-hole sections of three wells followed by drilling of the reservoir sections.

As reported earlier in August, Mubadala’s that MNA-24H and MNA-23H development wells had reached final total depth and were tested with 1033 Bopd and 945 Bopd, respectively.

Mubadala’s partner in the project Tap Oil said on Wednesday that both wells have been completed and handed over to production operations.

“Currently multi-rate testing is being carried out on both wells ahead of moving into long term production. Tap will provide a further update on these wells once production from the wells has stabilized,” Tap Oil, Mubadala’s partners in Manora, said on Wednesday.

As for the third well, MNA-22H, on it reached final total measure depth of 2113 m, Tap Oil said Wednesday.

“Petrophysical interpretation of well logs show a total oil net pay of 56.5 m in the 490-60 and 500 sands. The well has been suspended and will be completed with a workover rig at a later date. Tap will provide a further update on MNA-22H when the work over activities have been completed,” the company said.

According to Tap, the Ensco 115 rig was demobilized on August 14, 2019, but is expected to return for further exploration drilling in November 2019.

Discovered in 2009, the Manora offshore development is located in the G1/48 block in the Gulf of Thailand, approximately 80 kilometers offshore in 44 meters of water depth. It started production in November 2014. Mubadala at the time said that peak production would be around 15000 barrels a day, with the commercial life of the field projected to exceed 10 years from the start of production.

According to a report recently released by TAP, this peak was achieved soon after the start-up. TAP’s report from May showed that Manora’s April 2019 gross production had been 5,334 bopd (1,600 bopd net to Tap).

TAP at the time said that infield and nearfield drilling, and ongoing workovers were underway to enhance production, reserves, and economic life of the Manora Asset.

As reported in March 2019, apart from three development wells at the Manora, the partners also approved one firm exploration well, scheduled for November 2019, and one further exploration well contingent upon rig slot availability.
