Mubadala Petroleum has started drilling the fourth and fifth of 15 planned development wells at the Manora oil field in the northern-Gulf of Thailand.
An Atwood Orca jackup drilling unit is being used to drill the MNA-04 and MNA-05 wells to final target depths of 3,430m and 1,934m, respectively.
MNA-04 is the first of the five planned water injector wells, while MNA-05 will be completed with electric submersible pumps.
Mubadala has also revealed that the third Manora well, MNA-03, was drilled to its final target depth.
The Manora A platform is situated in the Gulf of Thailand in 46m of water. The development programme includes the drilling and completion of 15 wells with ten producers and five injectors.
The programme is expected to be completed by the end of the first-quarter of 2015.
Production at Manora is expected to start in the second-half of October, instead of ealier plans of the end of the third-quarter of this year.
Proven and probable reserves held in Manora’s primary reservoir are estimated at 20.2 million barrels gross.
The Manora oil field, located in the G1/48 concession of the Gulf of Thailand, lies in 50m of water, approximately 75km offshore Thailand.
Mubadala Petroleum operates the concession and holds a 60% interest via its affiliate Pearl Energy.
Australia-based Tap Energy holds a 30% interest and Thailand-based Northern Gulf Petroleum owns the remaining stake.
