Explanation:
Bombay High (now Mumbai High) field is an offshore oilfield located in the Arabian Sea, approximately 160km west of the Mumbai coast, India. Discovered in 1974, the field commenced production in 1976 and is operated by the Oil and Natural Gas Corporation (ONGC).
The oil field consists of two blocks named Mumbai High North (MHN) and Mumbai High South (MHS). The blocks were divided based on shale barrier, assisting in independent exploitation of reserves at both sites.
Mumbai High field currently holds 1,659 million metric tonnes (MMt) of oil and is producing approximately 12MMt a year.
ONGC’s board granted approval for the second phase of MHN Redevelopment project in January 2009, followed by the third phase in June 2014.
Mumbai High field discovery details
Mumbai High field was discovered in February 1974 by the Russian and Indian team from seismic exploration vessel Academic Arkhangelsky while mapping the Gulf of Cambay between 1964 and 1967.
The discovery of Mumbai High field and subsequent other discoveries of other oil and gas fields in the western offshore area has changed the oil industry in India.
In 2018, a major oil discovery was made from well WO-24-3, which indicated a potential of approximately 29.74 million metric tonnes of oil equivalent (MMtoe) in the area.
Geology and oil reserves at Mumbai High field
Different oil and gas reservoirs, such as L-I, L-II, L-III, L-IV, L-V, basal clastics and fractured basement from top to bottom, are present in Mumbai High field. L-II and LIII are primarily limestone oil reservoirs dating from the Miocene age, further classified into several layers.
Mumbai High field has approximately 1,659Mt of total reserves in place.
Mumbai High field development details
ONGC announced its plan for the redevelopment of Mumbai High field in 2000. It planned to spend approximately Rs90bn ($200m) in five years for the project. The plan was divided into two phases. The first phase started in 2000 and was completed in December 2006.
Phase one is expected to yield an additional crude oil production capability of 23.25MMt and 6.10 billion cubic metres (bcm) of gas by 2030 from 73 new wells and ten sidetrack
