Bayu Undan infill program completed under budget and ahead of schedule

Santos has released a statement announcing first gas from the third and final well of the Bayu Undan infill well program, and delivery of the whole project under budget and ahead of schedule.

According to the statement, a final investment decision (FID) was taken in January 2017 as part of the long-term development plan for Bayu Undan gas/condensate project located in the Timor Sea. The drilling program involved two platform wells, as well as one subsea well connecting into existing offshore infrastructure.

The Managing Director and CEO of Santos, Kevin Gallagher, said: “This drilling campaign has been very successful, providing strong subsurface results, with the whole project having been executed approximately 40% below budget and the final well brought on-line over three months ahead of schedule.

“The program’s success means that we have delivered higher liquids production and increased offshore well capacity. Operator ConocoPhillips has done an excellent job in executing such an efficient drilling program.”

Santos claims that the wells were drilled with the Noble Tom Prosser rig, which has now been contracted by Santos to undertake a 2019 drilling program, including appraisal of the recent Dorado oil discovery offshore Western Australia.

Santos holds an 11.5% interest in the Bayu Undan joint venture and the Darwin LNG plant, both of which are operated by ConocoPhillips. In addition to this, Santos has a 25% interest in the Barossa joint venture. The Barossa gas field is currently in front end engineering and design and is reportedly the leading candidate to backfill Darwin LNG when Bayu Undan production stops. According to the statement, Barossa would more than double Santos’ production in Northern Australia with FID targeted for late next year.
