ConocoPhillips Grissik Ltd., a unit of U.S. oil and gas company ConocoPhillips, shut down the Suban gas field in Indonesia on Feb. 23 until March 1 for a planned maintenance, Indonesia’s upstream oil and gas regulator SKK Migas said Feb. 25.

ConocoPhillips, which operates the field, is making adjustments to its gas distribution during the shutdown, SKK Migas said in a statement to Reuters.

The operator will maintain gas supply to Singapore’s Gas Supply Pte Ltd. (GSPL) at minimum requirement of 170 billion British thermal units per day and will reallocate some of its supply to GSPL for other buyers during the maintenance.

Some of the gas supply for GSPL will be allocated to state-controlled PT Perusahaan Gas Negara for electricity supply in Batam, SKK Migas said

The Suban Field is part of the Corridor Block in South Sumatra, Indonesia's third-largest gas block, which is targeted to produce 145,000 barrels of oil equivalent per day of gas in 2019.
