India-based Oil and Natural Gas (ONGC) has outlined a plan to strengthen its western offshore fields in the country, to serve as its primary hub for oil and gas production.

The proposed two-phase plan will allow the company to process gas from its fields at any of its onshore facilities, Livemint reported.

As part of the plan, ONGC intends to lease out part of its existing offshore drilling rigs, pipelines and onshore assets to new energy companies.

"With this kind of an investment in increasing production and setting up infrastructure, our presence in western offshore will be unmatched by any company in India."

In addition, the company will complete additional pipeline work and purchase infrastructure at the Tapti gas field in the western offshore region to transport gas from its Daman field, which will soon start production.

With the proposed plan, ONGC will be able to produce 50 million metric standard cubic metres per day (mmscmd) of natural gas by 2020, compared with the existing 30mmscmd capacity.

ONGC executive director and Bassein and satellite assets manager Moitra was quoted by the newspaper as saying: "Once new companies step in to develop the marginal fields, they can use our infrastructure available in the western offshore for a fee. This will be a win-win for both.

"With this kind of an investment in increasing production and setting up infrastructure, our presence in western offshore will be unmatched by any company in India and we can get tolling, processing and transportation fees from any new company entering the region."

ONGC owns mid-sea assets, including Mumbai High, Bassein and satellite fields, and Neelam and Heera fields off the west coast.

The company has secured regulatory approval to purchase Tapti gas field infrastructure from BG India, including Tapti processing platform and a 70km pipeline connecting the Hazira complex.
