Australian oil and gas major Santos has awarded a subsea contract to McDermott International for the Bayu-Undan infill well Phase 3C project in the Timor Sea.
The subsea, engineering, procurement, construction and installation (EPCI) contract involves a tieback of a single in-field well to existing facilities.
This will be carried out by re-using the existing flexible flowline with a new umbilical and certain infrastructure.
Claimed to be one of Timor-Leste’s largest gas fields, the Bayu-Undan field is located approximately 500km off the north-west coast of Darwin, Australia, and 200km off the south-east coast of Timor-Leste.
McDermott’s office in Perth will be responsible for managing work on the Phase 3C Project, which already started in May 2021.
Santos’ operated interest in Bayu-Undan stands at 43.4%. Other partners include SK E&S, Inpex, Eni, JERA, and Tokyo Gas.
Earlier this year, Santos made a final investment decision (FID) for the $235m Phase 3C infill drilling programme at the Bayu-Undan field.
The drilling programme includes two platform wells and one subsea well to develop further gas and liquids reserves.
The ‘Noble Tom Prosser’ semi-submersible will be used to drill the wells, with production planned to commence in the third quarter of this year.
The aim is to extend field life and boost production from the offshore facilities and the Darwin LNG plant.
