Tap Oil Limited has informed that all eleven Manora development wells, located in the Northern Gulf of Thailand, have been completed and the drilling rig has now moved off location.
Mubadala Petroleum is the operator of the Manora Oil Development joint venture and Tap Oil Limited has 30% interest.
Manora is now producing from six wells: MNA-01, MNA-02, MNA-03, MNA-05, MNA-07 and MNA-08 with MNA-11 expected to start production this week. Manora has been producing above 15,000 bopd (gross), and on occasion above 16,000 bopd (gross) since the six wells have been in production.
MNA-01 and MNA-02 started production on November 11, 2014, with MNA-03 following a day later. MNA-05 started production on November 23, 2014. All of these wells have been completed with ESP pumps, exhibited high productivity as expected, and are producing free of water and sand. Production from the above wells occurs in the Central Fault Block 600 sand reservoirs.
MNA-04, MNA-09ST1 and MNA-10 are currently injecting water to support production from 600 reservoir sands in the Central Fault Block. Pressure response due to water injection has already been observed in the Central Fault Block.
MNA-07, the first producer well from the East Fault Block, was put on production in early January with a tested rate of 1,332 barrels oil per day (gross) with 40% watercut which has increased to 64% watercut at present. MNA-08 producer well from the East Fault Block started production on February 21, 2015. MNA-08 is currently producing oil at the rate of 2,377 barrels oil per day (gross) with 14% watercut.
The last two wells, MNA-11 producer from the Central Fault Block and MNA-13 water injector in the East Fault Block have been successfully drilled to final Total Depth. MNA-11 intersected highest net oil pay count (98m) in 600 reservoir sands of any of the wells. This confirms the Operator’s geological model of thicker sands in the centre of the Central Fault Block. MNA-11 is expected to start production this week and MNA-13 has been completed and is currently injecting water to support production from the East Fault Block.
Following a review of the results from the development drilling programme, the Manora joint venture agreed that two wells (one producer and one injector) are no longer required and also to defer two producer wells. The development plan had previously forecast up to 15 development wells (10 producers and 5 injectors). The Operator (Mubadala Petroleum) has confirmed that peak production of 15,000 barrels per day (gross) has now been achieved and can be maintained with only 7 producer wells (instead of the original 10 producer wells).
