State-owned Oil and Natural Gas Corporation (ONGC) has made oil discovery in WO-24-3 well located west of Mumbai High fields in Arabian Sea. The well is estimated to hold in-place reserve of about 20 million tonnes.
The new discovery comes almost 50 years after ONGC began production in Mumbai High, which is India’s biggest oil field. It currently produces 205,000 barrels of oil per day (just over 10 million tonnes per annum).
In all, ONGC had tested nine objects or zones and all of them were found to be hydrocarbon bearing. The last object tested flowed 3,300 barrels of oil. ONGC is also carrying out further appraisal of discovery and has intimated upstream regulator Directorate General of Hydrocarbons (DGH). The new find will add to existing production capacity of Mumbai High in less than two years time. It will help ONGC to maintain production levels from basin for a longer time than currently estimated.
Mumbai High is ONGC’s flagship oil producing assets. It along with other small fields along western offshore have produced 16 million tonnes per annum of oil, which is 44% of India’s total crude oil production of 36 million tonnes. ONGC produced 25.5 million tonnes of oil in 2016-17, which will reach 28-29 million tonnes by 2019-20.
