ONGC plans to shutdown two production complexes at the Bassein field to hook-up new facilities leading to fall in natural gas availability from 42 million standard cubic meters per day to 29-31 mmscmd, a company official said.
The company will shut BPB process complex from January 1-25, 2008, and BPA complex from February 14-28, 2008, as it needs to hook-up the South Bassein field and the Vasai East field to the production system.
ONGC has invested Rs 2,937 crore in additional development of the South Bassein field and another Rs 1,688 crore in the Vasai East field.
Under these two major development projects, two offshore platforms, namely BCPA-2 and BCPB-2, are being installed near the existing process complexes of BPA and BPB at South Bassein field.
"These two new platforms will be bridge connected to existing BPA and BPB process complexes and during hook-up, integration and pre-commissioning, the BPA and BPB production facility will require shutdown," the official said.
The shutdown of BPB facility for 24 days would reduce gas output by 13.5 million standard cubic meters per day and the 15 day shutdown of BPA facility to cut output by 11 million standard cubic meters per day.
As against current production of 42 MMSCMD, gas supply is expected to be in the range of 29 to 31 MMSCMD during the shutdown period.
