Guwahati: The Oil and Natural Gas Corporation (ONGC) is looking at investing around Rs 6,000 crore to drill nearly 200 wells across various fields in Sivasagar district of Assam.
In a letter to the environment ministry, the country’s largest producer of oil and gas has reportedly said that the Assam asset (Nazira) covers the entire North Assam Shelf, which consists of major oil and gas producing fields such as Geleki, Lakwa, Lakhmani, Laipilingaon, Rudrasagar, Charali, Changmai gaon and Disangmukh oilfields and satellite fields in Sivasagar district.
The letter also reportedly mentions the Nazira sector oilfields, though established, need to be developed through drilling at various locations. For the development of these fields of North Assam Shelf, 200 development locations are proposed to be drilled during the next seven years starting from the year 2018-2019 in the fields of Sivasagar district.
The ONGC has reportedly proposed the usage of electrical type rigs for undertaking drilling in the proposed locations, which will require about three to four months.
The ONGC’s cumulative crude oil production from Assam fields during the April-October 2018 period increased 2.12 per cent to 585.17 thousand tonne (TMT), while natural gas production during the period from Assam fields declined 4 per cent to 288 million standard cubic meters (MMSCM).
