Re: Offshore ONGC

Bombay High (now Mumbai High) is a offshore oilfield situated in the Arabian Sea around 160km west of the Mumbai coast. Found in 1974, the field has been worked by Oil and Natural Gas Corporation (ONGC). Generation at the field began in 1976.

The oil field comprises of two pieces named Mumbai High North (MHN) and Mumbai High South (MHS). The pieces were isolated in view of shale obstruction helping with autonomous abuse of stores at the north and south fields of Mumbai high.

Presently, the field has 1,659 million metric tons (MMT) and is creating around 12MMT a year.

The organization's board allowed endorsement for the second period of Mumbai High North (MHN) Redevelopment venture in January 2009.

ONGC chief said, "Stage II redevelopment of Mumbai High is going on. About INR 90,000m will be pumped into it throughout the following 3-4 years. It is a long haul program."

Field advancement

ONGC declared its arrangement for Mumbai High redevelopment in 2000. It wanted to spend around INR 90,000m in five years for redeveloping the field. The redevelopment arrangement has been isolated into two stages. The primary stage began in 2000 and was finished in December 2006.

The stage I is relied upon to yield an extra raw petroleum creation of 23.25 MMT of raw petroleum and 6.10 BCM of gas by 2030, from 73 new wells and ten derail penetrated.

The combined oil creation from stage I redevelopment wells was 9.34MMT and total gas generation was 2.89BCM until March 2008.

The field achieved its top of creation of 400,000bopd (barrels of oil every day) in 1985 and proceeded at same rate until 1989.

Decrease in oil and gas generation prompted the need of a redevelopment arrangement. The creation declined step by step and achieved 220,000bopd in 2001 and 10 million metric standard cubic meters of gas every day (mmscmd or mmcmd).

ONGC contributed around INR80,000m under stage I for upgrading the productivity and controlling the decrease in oil and gas generation. Under stage I, 29% of 1,659 million tons of aggregate stores were moved forward.
