New Delhi, April 25 State-owned Oil and Natural Gas Corp (ONGC) today said its board has approved an investment of Rs 600 crore for development of Western Periphery oil and gas deposits off the west coast.
The Board in its meeting today “approved investment proposal for Development of Western Periphery as a part of Mumbai High South Field, Phase III Redevelopment, at an estimated cost of Rs 600.17 crore,” the company said in a statement here.
The project, scheduled to be completed by December 2014, is expected to result in incremental production of 1.031 million tonnes of oil and 213.817 million cubic meters of gas by March 2030. “The project envisages installation of one 12 slot four-legged unmanned platform, drilling of 10 wells and associated modifications and pipelines for well fluid, gas lift and water injection,” it said.
Mumbai High South field’s Phase-I redevelopment project, which was completed in 2007, helped significantly arrest the decline in production and increased it from level of 131,400 barrels per day (bpd) in June 2001 to 173,000 bpd by beginning of 2007. The phase-II which was launched after the completion of Phase-I to further improve the recovery factor is in advance stage of completion and is expected to improve oil recovery to 34.5% by March 2030.
