Bombay High is an oil field 176km (109 mi) off the coast of Mumbai, India, in around 75 m of water. The oil processes are run by India’s Oil and Natural Gas Corporation (ONGC). Bombay High field was found by a Russian and Indian oil exploration team operating from the seismic exploration vessel Academic Arkhangelsky during mapping of the Gulf of Khambhat (earlier Cambay) in 1964-67, followed by a thorough survey in 1972. The naming of the field is credited to a team from a survey run in 1965 examined in the Rashmi building in Peddar Road, Cumballa Hill, Bombay. The first offshore well was ruined in 1974.
Every oil resource rock wants Structural traps which are mostly salt dome, coral reefs, fault trap and fold trap. In case of Bombay High field, the structure is a “north-northwest to south-southeast trending especially plunging Anticline with a faulted east limb”, 65 kilometres long and 23 km wide”, and is the most probable cause to call it “Bombay High”.
This is a carbonate reservoir, the major producing zone, L-III, involving of sedimentary cycles of lagoonal, foraminiferal mound, algal mound and then a coastal marsh, capped by a post-middle Miocene shale.
Bombay High has three blocks parted by east-west trending faults, all three with different gas-oil associates but about 1355 m deep As of 2004, it supplied 14 per cent of India’s oil requirement and accounted for around 38% of all domestic production.
On 27 July 2005, the main fire destroyed the production platform, leaving around 22 people dead despite rescue actions taken by the Indian Coast Guard. The platform accounted for 110,000 tubs per day (17,000 m3/d), or 15% of India’s oil production. Rebuilding this is probably to take upwards of 4 months and projected to cost about Rs. 1200 crore or US$300 million.
ONGC approved construction of 7 pipelines with risers and related top-side facilities in MHN in April 2007. These pipelines are energetic for optimum utilization from Mumbai High. Crude oil formed from Bombay High is measured to be of very good quality as compared to crudes produced in the middle east. Bombay High crude has more than 60 per cent paraffinic content and light Arabian crude has just 25 per cent paraffin.
In November 2009, the output of Bombay High fields that accounts for half of India’s domestic oil production cut down 5.3% to 347,197 barrels per day (55,199.9 m3/d). As per 2018, the production of the field was 205,000 barrels per day (32,600 m3/d). Bombay High touched its peak production level in 1998 with 20MMt a year. Along with its contiguous fields, it produced at the rate of 12.8Mmscmd of gas prior to the new redevelopment projects.
Bombay High (Mumbai High) is an oil field situated in the Arabian Sea, about 160km west of the Mumbai coast. Discovered in 1974, the field started production in 1976 and is worked by Oil and Natural Gas Corporation (ONGC). The field presently holds 1,659 million metric tonnes (MMT) and is producing about 12MMt a year.
