Oil and Natural Gas Corporation Ltd. (ONGC) Board, in its 187th meeting on 28th January 2009, has approved the second phase of Mumbai High North (MHN) Redevelopment project, which will yield an incremental crude oil production of 17.354 Million Metric Tonnes (MMT) and Natural Gas 2.987 Billion Cubic Metres (BCM), aggregating to 20.34 Million Tonnes of Oil equivalent, by March 2030.

The total cost of this Redevelopment Project is Rs. 71.3339 billion ($1.45 billion). The project is scheduled to be completed by September 2012.

The decision to launch Phase II of Mumbai High North Redevelopment comes after the success of the first phase, which was launched in October 2000 (and completed in December 2006) and is likely to result in incremental gain of 23.25 MMT of crude oil and 6.10 BCM of gas by 2030, from 73 new wells and 10 side-track wells drilled in 1st phase. Till March 2008, the cumulative oil production from Phase I redevelopment wells has been 9.34 MMT against plan of 8.46 MMT and cumulative gas production has been 2.89 BCM against plan of 1.87 BCM.

Mumbai High field was discovered in 1974 and was put on production in May 1976. The field is currently producing a little over 12 MMT a year (245,000 bopd) and has already produced 24 per cent of the Initial-Oil-In-Place (IOIP) cumulatively. The field has two hydrocarbon pools in North and South and for development purpose, these have been delineated as two projects – Mumbai High North (MHN) and Mumbai High South (MHS). Both MHN and MHS were developed separately and are currently (2007-08) producing 4.34 MMT and 7.69 MMT of crude oil respectively.
