Sri Trang final drilling update

The Sri Trang-1 exploration well is located in the Reservation Area of the G1/48 concession in the Gulf of Thailand approximately 18 kilometres north northeast of the Manora oil development. Mubadala Petroleum is the operator of G1/48. The well was spudded at 17.30 hrs (WST) on 17 May 2016 in 40 metres of water by the Atwood Orca jackup drilling unit and was drilled to an extended final total depth of 2,814 meters measured depth. The test results confirmed the presence of oil in poor quality reservoir sand. The samples collected from three other zones confirmed the presence of water. Although the oil is not in commercial quantities, the Sri Trang-1 discovery has validated the hydrocarbon prospectivity of the Northern Kra Basin. The drilling cost of the Sri Trang-1 well will be offset against the G1/48 Reservation Area fee (~US$3.8 million) paid to the Thai Department of Mineral Fuels by the Joint Venture of the Reservation Area in the G1/48 concession. It is estimated that Tap may be required to contribute up to a further US$0.1 million above the Reservation Area refund.

Manora Oil Development Completed

Tap Oil Limited (ASX:TAP) provides the following update on the Manora Oil Development in the Northern Gulf of Thailand (Tap 30% interest). Mubadala Petroleum, Operator of the Manora Oil Development joint venture, has advised 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. 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. 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 commence production in the last week in April when the rig leaves the platform. MNA-16 is expected to commence production during the first week in May once it is connected to the production system. 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 commence drilling of the Sri Trang-1 exploration well in the Reservation Area of the G1/48 Concession in mid May 2016. Tap has 2P reserves of 4 mmbbls (13.2 mmbbls gross) as at 31 December 2015 booked for Manora (see annual report ASX release 22 April 2016). Tap will review these reserves and contingent resources following development drilling and production performance.

The extension continues the drilling services until the new contract end date of October 28, 2016. Additionally, the agreement adjusts the operating day rate to approximately $85,000 from November 1, 2015 until the new contract end date.

Manora development drilling completed

Tap Oil Limited (“TAP”) has provided an update on Manora production and development drilling at the Manora Oil Development in the Northern Gulf of Thailand (TAP 30% interest). All eleven Manora development wells have been successfully completed and the Atwood Orca drilling rig has now moved off location. 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 commence 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 11th November 2014, with MNA-03 following a day later. MNA-05 started production on 23rd November 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 21 February 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 commence 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).

Mubadala begins development drilling at Manora in Thailand

Tap Oil Limited (Tap) has provided the following update on the Manora Oil Development in the Northern Gulf of Thailand. Mubadala Petroleum, Operator of the Manora Oil Development joint venture, has advised that at 10.00 (AWST) the ‘Atwood Orca’ jackup drilling unit spudded the first of 15 planned development wells, MNA-02. The MNA-01 and MNA-02 wells will be batch drilled to final total depths of 2,104 m and 2,441 m measured depth respectively and shall be completed with electric submersible pumps (ESPs) ahead of handover to Production. Drilling and completion of both wells is planned to take 24 days on a trouble free basis. Both wells are required ahead of introduction of hydrocarbons to the Manora production facility. Production is expected to occur shortly after the completion of the MNA-01 and MNA-02 wells. The Manora A platform is located within the Gulf of Thailand in 46 metres of water. The development drilling program calls for drilling and completion of 15 wells (10 producers and 5 injectors), with the program expected to take until the end of Q1 2015. Tap has 2P reserves of 6.1 mmbbls (20.2 mmbbls gross) and 2C contingent resources of 3.2 mmbbls (10.9 mmbbls gross) booked for Manora (ASX release 27 October 2011). Tap will review these reserves and contingent resources following development drilling and production performance. Tap will make scheduled announcements upon commencement of drilling and completion of each well or each batch. Tap’s next expected announcement is at the completion of MNA-01 and MNA-02.

Nong Yao is expected to commence oil production in the first half of 2015. G11/48 covers 3,374 sq km over the southern margin of the Pattani Basin and the northwest margin of the Malay Basin in water depths of up to 75 metres. The block also contains the Angun and Mantana oil and/or gas discoveries. KrisEnergy holds 22.5% working interest in G11/48. Mubadala Petroleum G11 (Thailand) Limited, the operator, has a 67.5% working interest and Palang Sophon Limited holds 10%. Rojana-A was drilled using the ‘Atwood Orca’ jack-up rig owned by Atwood Oceanics.
