Assam: Blowout at ONGC well; emergency services pressed to control spewing gas

No injury has been reported so far and the well has not caught fire yet.

"There is an uncontrolled flow of gas. We are trying to control the well. All senior officials are at the site. We are actively mobilising all resources required for controlling the well and we hope to do it as soon as possible. Work is underway," he added.

Another official said that there has been no injury at the site, and the well has not caught fire yet.

"It is an old crude well and not under production. A perforation job was underway for zone transfer. It is a kind of servicing of the well. The production was supposed to start from a new zone after the perforation job.

"At the time of the incident, the logging perforation operation was going on. Suddenly gas started coming out in an uncontrolled manner immediately after the perforation, leading to the blowout," he added.

Presently, the well site is under control and all emergency services have been deployed, the official said.

"Currently, a well killing job is in progress. Some locals in the nearby areas have decided to leave their homes temporarily fearing a blast from the blowout site," he added.
