Workover medicine for Oil India wells

Vol 23, PW 5 (16 Jan 20) News in Brief

Oil India is facing an acute shortage of workover rigs as it scrambles to revive and restore full production in Assam following violent December protests against the Citizenship (Amendment) Act, 2019.

 "More than 400 producing wells were affected and of these more than 300 were badly affected," reports a source. "We did not plug the wells but when production substantially reduces a well's potential is adversely affected and we must depend on workovers."

Oil India has only 19 workover rigs in Assam, all working on existing wells. "Workover and stimulation plans are a priority," he adds.

"But it is difficult to requisition (more) workover rigs for short-term jobs." Our source adds Assam production fell by 50% during the worst protest days between December 9-15 when Oil India offices and field operations were forced to shut down.

Only now is it creeping back up. "If our December production were to continue now we would only produce 1m t/y not the 3.5m t/y we usually report," he says.

 "Right now we are just inching back up to over 3m t/y but otherwise production had gone down to 1m t/y." In the first six months of 2019-20, Oil India reported 1.63m tonnes production.
