Abu Dhabi-based Mubadala Petroleum has spudded two more wells on the Manora field off Thailand. Drilled with Atwood Oceanics’ jackup Atwood Orca, the MNA-04 and MNA-05 wells represent the fourth and fifth wells, respectively, of a planned 15 developmental well campaign set to end 1Q 2015.
Joint venture partner Tap Oil said that wells MNA-04 and MNA-05 will be drilled to final target depths of 3,430m and 1,934m measured depth respectively. MNA-04 is the first of five planned water injector wells. The remaining 10 wells are planned to be producers. As part of the field's development plan, a moored, site-specific FSO is planned to pull dual-duty as an accommodation hub.
Days ago, on 29 September, Tap Oil announced that while batch drilling of the first three wells were progressing ahead of schedule, first oil would be pushed back to the second half of October. Originally planned for 3Q 2014, the Australian company said in a statement that a combination of poor weather and setbacks in platform commissioning caused the delay. Commissioning work is currently underway.
Located in the Gulf of Thailand, the Manora A platform is in 46m of water depth. In its 29 September announcement, Tap Oil says that the initial development wells, MNA-01 and MNA-02, encountered just over 52m and 48ft of net oil pay, respectively, in the three 600 series reservoirs of the central fault block. Well MNA-03 targets a third reservoir and has also been drilled to its target depth.
Production is expected to ramp up to a peak rate of 15,000bo/d, Tap Oil said. The company has said it has 2P reserves of 6.1MM bbl (20.2MM bbl gross) and 2C contingent resources of 3.2MM bbl (10.9MM bbl) booked for Manora
Operator Mubadala holds 60% interest in Manora. Tap Oil (30%) and Northern Gulf Petroleum (10%) round out the partnership.
