ONGC to drill 200 Wells across Assam Oil and Gas Fields

Jan 8,2019

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.


ONGC’s cumulative crude oil production from Assam fields during the April-October 2018 period increased 2.12% to 585.17 thousand tonnes (TMT), while natural gas production during the period from Assam fields declined 4% to 288 million standard cubic meters.


ONGC’s crude oil production in October 2018 fell 6.56% to 1,765 TMT, as compared to 1,889 TMT produced in the corresponding month a year ago.


Cumulatively, total crude oil production by ONGC during the April-October period dropped 5.68% to 12,442 TMT, as compared to 13,191 TMT produced in the corresponding period a year ago.
