Santos starts phase 3C infill drilling at Bayu-Undan

Santos on May 25 announced the start of the phase 3C infill drilling programme at the Bayu-Undan field, in Timor-Leste offshore waters.

The programme, given a final investment decision in January this year, comprises three production wells and will develop additional natural gas and liquids reserves, extending field life as well as production from the offshore facilities and the Darwin LNG plant.

Santos CEO Kevin Gallagher said the wells will be drilled using the Noble Tom Prosser jack-up rig, with the first production expected in the third quarter of 2021.

"The infill drilling programme will add over 20mn barrels of oil equivalent gross reserves and production at a low cost of supply and importantly extends the life of Bayu-Undan and the jobs and investment that rely on it,” Gallagher said.

Timor-Liste petroleum and mining regulator Autoridade Nacional do Petroleo e Minerais president Florentino Soares Ferreira said the drilling marks the first campaign in the Bayu-Undan field as Timor-Leste offshore waters, following the ratification of the Maritime Boundary Treaty between Timor-Leste and Australia.

Santos has a 43.4% operated interest in Bayu-Undan. The remaining interest is held by South Korea's SK E&S, Japan's Inpex, Italy's Eni, Jera, and Tokyo Gas.
