India’s largest producer of oil and gas, Oil and Natural Gas Corporation, is looking at drilling 200 wells across various fields in Sivasagar district of Assam at a cost of INR 6,000 crore, the firm said in an application submitted to the environment ministry. On 20 December the Expert Appraisal Committee had recommended the project for grant of environmental clearance, subject to compliance of terms and conditions. The Assam asset (Nazira) covers the entire North Assam Shelf, which consists of major oil and gas producing fields such as Laipilingaon, Rudrasagar, Charali, Geleki, Lakwa, Disangmukh, Changmai gaon, and Lakhmani oilfields and satellite fields in Sivasagar district.
ONGC said that “Though these Nazira sector oilfields have been established, they 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 in the fields of Sivasagar district during the next 7 years starting from the year 2018-2019.”
According to the company, ONGC-owned electrical type rigs are proposed to be deployed for undertaking to drill in the proposed locations which will require about 3 to 4 months to drill each well.
