The Mumbai High Field, formerly called the Bombay High Field,^[1] is an offshore oilfield 176 km (109 mi) off the west coast of Mumbai, in Gulf of Cambay region of India, in about 75 m (246 ft) of water.^[2] The oil operations are run by India's Oil and Natural Gas Corporation (ONGC).

Mumbai High field was discovered by an Indo-Soviet oil exploration team operating from the seismic exploration vessel Academic Arkhangelsky^[2] during mapping of the Gulf of Khambhat (earlier Cambay) in 1964–67, followed by a detailed survey in 1972.^[2] 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, Mumbai. The first offshore well was sunk in 1974.^[2]

Every oil resource rock requires Structural traps which are mainly salt dome, coral reefs, fault trap and fold trap. In case of Mumbai 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",^[2] and is the most probable reason to call it "Mumbai High".
