The ConocoPhillips-led group at Bayu-Undan gas-condensate field in the Timor Sea reported the completion of its three infill well program under budget and ahead of schedule. The third and final well was brought on line Dec. 3.
A final investment decision for the program was made in January 2017 as part of the long-term development plan for the Bayu-Undan project. The program is comprised of two platform wells and one subsea well connecting into the existing offshore infrastructure.
The infill project came in 40% below budget and 3 months ahead of schedule. This has resulted in higher liquids production and increased offshore well capacity.
The wells were drilled with the Noble Tom Prosser rig, which has now been contracted by Adelaide-based Santos Ltd. to undertake a number of wells, including an appraisal of the recent Dorado oil discovery off Western Australia.
Santos also holds 11.5% of the Bayu-Undan joint venture and the onshore Darwin LNG facilities. Santos also has a 25% interest in the Barossa joint venture.
Barossa field, which lies in the eastern Timor Sea, is currently in front-end engineering and design phase and is the leading candidate to backfill the Darwin LNG plant when gas flow from Bayu-Undan ceases. A final investment decision for Barossa is expected late in 2019.
