Oil India Limited (OIL), India's second largest National Exploration & Production Company, through its exploratory efforts has made one Hydrocarbon Discovery at Well Dinjan-1 in Tinsukia Petroleum Mining Lease (PML) in the Upper Assam Basin during the first half of FY 2020-21.

The well encountered multiple sands in Kopili, Narpuh and Lakadong+ Therria formations with a total net pay of about 10 m. On testing, a 3-m Lk + Th sand at a depth of 3,614 m, it produced gas @ 115,000 SCMD through 5 mm bean with FTHP - 3750 psi. This discovery will open up new areas for further oil & gas exploration in Assam and would help in enhancing the gas production with future appraisal & development activities.

In May this year, the company had reported a blow out during work over operations at Baghjan Oilfield in Tinsukia district, Assam. The incident occurred at a producing well called Baghjan 5 due to pressure control failure.
