The Oil and Natural Gas Corporation (ONGC), the country's largest producer of oil and gas is looking at drilling 200 wells across various fields in Sivasagar at a cost of Rs 6,000 crore.

The Expert Appraisal Committee had on 20 December recommended the project for grant of environmental clearance, subject to compliance of terms and conditions.

The company has said that 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.

"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 during the next seven years starting from the year 2018-2019 in the fields of Sivasagar district," the company said in its application.

For drilling, ONGC-owned electrical type rigs are to be deployed in the proposed locations and drilling of each well will require about three to four months.

The company has also submitted an application in this regard to the environment ministry.
