Recent developments

Thousands of locals were evacuated after blowout on May 27

The Baghjan well had been leaking oil and gas ever since a blowout on May 27 morning. Locals told The Indian Express that condensate (gas that has come in contact with water) could be found up to 5 km from the site. Thousands of people had reportedly been evacuated from surrounding villages. A variety of fish and an endangered Gangetic dolphin had died.

Information

Baghjan oil well drilled in 2006

The well had been drilled by OIL in 2006. It produces 80,000 standard cubic meters per day (SCMD) of gas. Officials told TIE on Monday that the current discharge was at 90,000 SCMD at a pressure of 4,200 PSI, higher than the normal 2,700 PSI.

Blowout

What is a blowout?

When pressure balance in a well is disturbed, it can lead to 'kicks' or changes in pressure. If left unattended, these kicks can cause blowouts. Geologist Siddhartha Kumar told TIE, "The force with which a pressure cooker releases steam is understandable. Imagine a situation where one million pressure cookers do the same in an uncontrolled manner." A blowout preventer is hence installed in wells.

What happened

Blowout occurred at Baghjan well when it was being serviced

OIL spokesperson Tridiv Hazarika told TIE that the well was being serviced and a new sand was being tested at another depth in the same well. They were also repairing an existing well-head, for which, the producing zone was temporarily shut and the blowout preventer was removed. Hazarika said the gas then started leaking and broke through the cement barrier. An inquiry is underway.
