Santos and its joint venture partners have sanctioned the start of the front-end engineering and design (FEED) phase for the development of the Barossa project to backfill Darwin LNG.
Santos managing director and CEO, Kevin Gallagher, said, “the Barossa FEED decision consolidates its position as the leading candidate for DLNG backfill when Bayu-Undan production ceases in the early 2020s.”
Barossa’s development would extend the operating life of Darwin LNG for more than 20 years, Gallagher said.
The Barossa gas field, 300 kilometers north of Darwin, sits within Santos’ Northern Australia portfolio, one of the company’s core long-life, natural gas assets.
FEED activities will involve engineering and commercial work aimed at finalization of the project’s technical detail, costs, LNG sales agreements and negotiation of access arrangements with the owners of DLNG and the Bayu-Undan to Darwin gas pipeline.
A final investment decision (FID) is targeted towards the end of 2019.
Contracts for field surveys and engineering for the floating production, storage and offloading facility (FPSO), subsea facilities and export pipeline will be awarded shortly.
The Barossa development concept consists of an FPSO, six subsea production wells to be drilled in the initial phase, supporting in-field subsea infrastructure and a gas export pipeline tied into the existing Bayu-Undan to Darwin pipeline, all located in Australian Commonwealth waters.
The project area encompasses petroleum permit NT/RL5 over the Barossa field and petroleum permit NT/RL6 to the south over the Caldita field to be developed as a potential future phase of the project.
Santos holds a 25 percent interest in the Barossa Caldita joint venture along with partners ConocoPhillips (37.5 percent and operator) and SK E&S (37.5 percent). Santos is also a joint venture partner in Darwin LNG with an 11.5 percent interest.
