Oil Rig at Bombay High
|Region||Gulf of Khambhat|
|Location||off the coast of Mumbai|
|Start of production||1974|
|Current production of oil||205,000 barrels per day (~1.02×107 t/a)|
|Year of current production of oil||2017|
Bombay High field was discovered by an 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 detailed survey in 1972. The naming of the field is attributed to a team from a survey run in 1965 analysed in the Rashmi building in Peddar Road, Cumballa Hill, Bombay. The first offshore well was sunk in 1974.
Every oil resource rock requires Structural traps which are mainly salt dome, coral reefs, fault trap and fold trap. In case of Bombay High, the structure is a "north-northwest to south-southeast trending doubly plunging Anticline with a faulted east limb", 65 km long and 23 km wide", and is the most probable reason to call it "Bombay High".
This is a carbonate reservoir, the main producing zone, L-III, consisting of sedimentary cycles of lagoonal, algal mound, foraminiferal mound and then coastal marsh, capped by a post-middle Miocene shale. Bombay High has three blocks separated by east-west trending faults, all three with different gas-oil contacts but approximately 1355 m deep.
As of 2004, it supplied 14% of India's oil requirement and accounted for about 38% of all domestic production.
On 27 July 2005, a major fire destroyed the production platform, leaving at least 22 people dead despite rescue measures taken by the Indian Coast Guard. The platform accounted for 110,000 barrels per day (17,000 m3/d), or 15% of India's oil production. Rebuilding this is expected to take upwards of 4 months and estimated to cost around Rs. 1200 crore or US$300 million.
ONGC approved construction of seven pipelines with risers and associated top-side facilities in MHN in April 2007. These pipelines are vital for optimum utilisation from Mumbai High.
Crude oil produced from Bombay High is considered to be of very good quality as compared to crudes produced in middle east. Bombay High crude has more than 60% paraffinic content while light Arabian crude has only 25% paraffin.
In November 2009, output of Bombay High fields, that accounts for half of the India's domestic oil production, fell 5.3% to 347,197 barrels per day (55,199.9 m3/d).
