Abu Dhabi-based Mubadala Petroleum has completed drilling of the MNA-15 and MNA-16 development wells at the Manora oilfield in the Northern Gulf of Thailand.
Mubadala Petroleum is the operator of the Manora Oil Development joint venture (JV), which is 30% owned by Tap Oil.
Northern Gulf Petroleum owns 10% interest in the development.
The MNA-15 and MNA-16 wells have been drilled to final total depths of 2,566m and 2,998m respectively. They were were completed with electric submersible pumps (ESPs) and targeted to the east fault block of the Manora oilfield.
MNA-15 discovered 44m of oil pay in three separate reservoirs and is planned as part of a four-zone selective completion produced by an ESP installed on a Y-block.
The well MNA-16 found 37m oil pay in four separate reservoirs and will be carried out as a six-zone selective completion.
Production from MNA-15 is expected to begin in the last week of this month, while MNA-16 is scheduled to start production during the first week of May 2016.
After completing drilling, the Atwood Orca rig has now moved location and is expected to begin activities on the Sri Trang-1 exploration well in the reservation area of the G1/48 concession in mid-May.
Tap Oil plans to review these reserves and contingent resources following development drilling and production performance.
In April 2015, Mubadala completed drilling of all 11 Manora development wells in the Northern Gulf of Thailand.
