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.
