Oil and Natural Gas Corporation is all set to implement the redevelopment plan for its Mumbai High offshore oil and gas field which is expected to add about 60 million tonne of additional oil and large quantity of associated gas over the next 30 years.
The redevelopment plan is being implemented after three years of sustained efforts and by amalgamating valuable geological and geophysical data, a press release issued by the company said.
Out of 32 million tonne of oil produced in the country every year, the prestigious Mumbai High field produces about 10 million tonne of oil.
The largest oil field in the country, Mumbai High, is located 160-km west-north-west of Mumbai city, in the Arabian Sea. ONGC had discovered the field in 1974.
The field holds nearly 1,600 million tonne of oil and till date 300 million tonne have been produced.
Currently, the field is producing 220,000 barrels of oil per day. Geoscientists feel that it still holds enormous potential for production of hydrocarbons, the release said.
Facing a declining production from the aging Mumbai High, ONGC in 1998 entered into a two-year catalytic consultancy contract with Gaffney Cline and Associates for mapping the field complexities and building a detailed geological model.
The multi-pronged scientific approach, towards understanding the geology of the area through 3-D seismic interpretation, use of special drilling fluids, drilling of healthy horizontal and conventional wells have paid dividends, the release added.
