Mubadala Petroleum has completed the development drilling on the Manora oil development in the Northern Gulf of Thailand.

Mubadala started drilling of the first of two development wells on the Manora field on March 22, 2016.

Tap Oil, the partner in the project with 30% interest, said on Wednesday that drilling of the MNA-15 and MNA-16 development wells has now been completed. The MNA-15 and MNA-16 wells have been drilled to final total depths of 2,566m and 2,998m (measured depth) respectively and completed with electric submersible pumps (ESPs). Drilling and completion of the two wells was completed in 38 days.

According to Tap, both development wells were targeted to the east fault block of the Manora oilfield. The MNA-15 well found 44 m of oil pay in three separate reservoirs. It will be completed as a four zone selective completion produced by an ESP installed on a Y-block.

Further, the MNA-16 well found 37 m oil pay in four separate reservoirs. It will be completed as a six zone selective completion produced by an ESP installed on a Y-block. MNA-15 is expected to start production in the last week in April when the rig leaves the platform, Tap said. MNA-16 is expected to start production during the first week in May once it is connected to the production system, the company added.

Production from the two wells is expected to return Manora to its plateau rate of 15,000 bopd gross (4,500 bopd net to TAP).

The Atwood Orca rig has now moved off location. The Atwood Orca is expected to start drilling of the Sri Trang-1 exploration well in the Reservation Area of the G1/48 Concession in mid May 2016.
