ONGC will invest over Rs. 10,600 crore in two major projects for further enhancing production from its Western Offshore fields. The projects are redevelopment (Phase-III) of its giant offshore field - Mumbai High (South) involving a capital investment of Rs 6,069 crore and integrated development of Mukta, Bassein and Panna formations at an estimated capex of Rs 4,620 crore.
 
The implementation of the Mumbai High (South) project will lead to incremental gain of 7.547 million tonne (MMT) crude oil and 3.864 billion cubic meter (BCM) gas by 2030. This project is designed to carry forward the success of the previous two phases of redevelopment project and give a new lease of life to the giant field.
 
The project comprises of drilling 36 new wells and 34 sidetrack wells, and facilities, ie installation of 3 well platforms, two clamp-on facility for wells on existing platforms, associated pipelines and modifications at 18 platforms. The facilities under the project are scheduled to be installed by April, 2017. Drilling of wells and the overall project completion is scheduled for March, 2019.
 
The Mukta, Bassein and Panna formations project located at a water depth of 50-70 m and about 80-90 km from Mumbai coast is designed to carry forward the success of the previous two phases of redevelopment through installation of booster compressors in year 1999 to boost delivery pressure from 55 to 105 Kg/cm2 and in 2007 to boost pressure from 25 to 60 kg/cm2. In order to further enhance the field life and increase recovery, this project envisages increasing gas pressure from 10 to 27 Kg/cm2.
 
The incremental production is expected to start in 2014-15 with peak incremental production rate of 10 MMSCMD of gas, 950 barrels of oil and about 1100 cubic meters of condensate per day by 2017-18. The cumulative production till 2027-28 is pegged at 19.56 BCM of Gas, 1.97 million cubic meter of Condensate and 1.83 MMT of Oil. The gas and condensate will be evacuated to Hazira Plant. The project is scheduled for completion by April 2017.
