Natuna Sea gas project on track for mid-2019 start-up

Development of the BIG-P project in the Natuna Sea offshore Indonesia is on schedule and on budget, according to operator Premier Oil.

Fabrication of the Naga and Pelikan platform deck extensions and the Pelikan and AGX platform spools was completed last month in the Batam yard, and numerous service vessels are in field for the offshore installations.

These will include the two deck extensions and the topsides components for the subsea control system at Gajah Baru and Anoa. All work should be completed by the end of September.

Fabrication of the subsea structures will start next month, and these will be installed with the flowlines, flexible risers, and umbilicals during the second offshore campaign planned in 2Q 2019.

A dive support vessel will then undertake the final hook up and tie-ins.

Drilling of the BIG-P development wells will begin during the first half of 2019 ahead of first gas, targeted for 3Q 2019. The supplies will help backfill Premier’s contracts into Singapore while also sustaining production from Natuna Sea block A.

The company and its joint venture partners have agreed on a farm-in offer to the Tuna PSC ahead of two appraisal wells planned for next year.

Seismic evaluation of associated prospects and leads on the remainder of the PSC should provide further opportunities once the Tuna field is developed, Premier added.

Elsewhere on block A, the exploration team is reprocessing the existing Anoa 3D datasets and analyzing production data from the WL-5X well, partly to assess the potential of the Lama play beneath the Anoa field, but also to identify potential infill drilling locations within Anoa.
