Ophir provides an update on recent drilling activity in Indonesia and Thailand.
Sampang – Indonesia
The Sampang PSC, offshore Indonesia is located in the East Java Basin in water depths of 48 metres to 65 metres and covers an area of 547.05 km2. Ophir has a 45% operated interest in the licence.
- In 2017 phase one of the Sampang Sustainability Project was completed. This involved switching the Oyong and Wortel fields to an unmanned gas only production system, decommissioning the floating production storage offloading vessel, and ceasing oil production.
- The fields are fully developed but there is upside through a potential phase two of the Sampang Sustainability Project which would lower the operating pressure of the onshore processing facility allowing for an additional 8.5 Bcf of gas (gross) to be recovered from Wortel and Oyong. This is currently classified as contingent resource.
Cumulative gross production to year end 2017 is 190 Bcf of sales gas and 9.8 MMstb of oil and condensate (Oyong: 103 Bcf and 9.7 MMstb; Wortel: 86.8 Bcf and 0.1 MMstb). Gross average 2017 production was approximately 46 MMscf of sales gas per day.
As of 1 January 2018 the licence contained 2P net reserves (on a working interest basis) of 2.6 MMboe.
