Oil India Limited (OIL), India’s second largest national exploration & production company, through its exploratory efforts has recently made two Hydrocarbon Discoveries in the Moran Petroleum Mining Lease (PML) in the Upper Assam Basin in the wells Borbhuibil-1 and Lakwagaon-1.
The well Borbhuibil-1 encountered multiple sands in Barail and Lakadong+Therria formations. On testing, a 15m Barail sand at a depth of 3,322m produced oil at the rate of 28 cubic metre/d. A 10m Lakadong+Therria sand at a depth of 4,300m produced oil at the rate of 100 cubic metre/d. The feasibility of bringing the discovery on production at the earliest is under study.
In the well Lakwagaon-1, discovery of a gross column of 30m oil sand in Barail formation has been made, which produced 42 cubic metre/d of oil on initial testing. The well is currently on production. The discoveries have opened up avenue for further exploration of already identified leads / prospects in the area.
