We at OSL Oil & Gas...

Orissa Stevedores Limited dived into the Oil and Gas industry in the year 2019 and is now a leading operating company in the upstream hydrocarbon sector of the Country. After a successful participation in seismic data acquisition & processing tender floated by Oil India Limited, we have been unstoppable. With our corporate office in Noida, we are now establishing two operational fields setup in the state of Assam. Our confidence supported by the industrial expertise of the team has made our ambitions limitless in this venture.

Since this journey began, we have participated in bidding for four clusters of Oil and Gas producing fields offered under Production Enhancement Contract regime (PEC) by ONGC & Oil India Limited. Our success in the PEC tender has already catapulted us into the league of operating companies in the upstream hydrocarbon sector of the country.

The Journey Has Begun

Our progress in the past year reflects  our sheer will and determination. As a response to our expertise, OSL was awarded two contract areas of Nambar and Chanmaigaon through International Competitive Bidding  in June 2019 under Production Enhancement Operations (PEO) by ONGC and Oil India Ltd.

Located in Sivasagar & Golaghat districts in Assam, Nambar contract area comprises two fields namely Nambar and East Lakhibari and is a part of Jorhat Asset of ONGC. The area is situated to the South-West of Jorhat town. ‘Nambar oil field’ and ‘East Lakhibari field’ were discovered & started producing in 1999 and 2003 respectively. Cumulative production from the cluster as on 01.04.2019 was 0.45 MMt of oil and 138 MMm3 of gas.

Changmai Gaon is one of the oldest discoveries made in 1984 where commercial production began in 1991 through the first well. The contract area comprises three fields namely, Changmaigaon, Disangmukh and Panidihing located in Upper Assam Shelf set up and is a part of Assam asset of ONGC. Panidihing and Disangmukh are relatively recent discoveries, where commercial production commenced in 2003 and 2007 respectively. Cumulative oil production from the cluster as on 01.04.2019 stands at 0.80 MMt. The cluster is currently producing oil at @ 25-30 m3/de. We have further identified production enhancement opportunities for the cluster, through drilling of infill wells, work-over jobs, facility optimisation and fit for purpose technology application.
