Public sector undertaking, Oil India Ltd has notified two Hydrocarbon Discoveries in the Upper Assam Basin. The discoveries were made 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 m3/d.
A 10m Lakadong+Therria sand at a depth of 4,300m produced oil at the rate of 100 m3/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 m3/d of oil on initial testing. The well is currently on production.
OIL said that the discoveries have opened up avenue for further exploration of already identified leads and prospects in the area.
