Guwahati: After 172 days of disastrous blowout, the flame atop the Baghjan Well no 5 has been successfully doused.
“The well has been killed with brine solution and is under control now. As of now there is no pressure in the well and the same will be observed for 24 hours to check if there is any amount of gas migration and pressure build up. Further operation to abandon the well is in progress” reveals Oil India Limited.
According to reports, the operation was headed by the eight-member global experts’ team along with OIL senior officials from the crisis management team (CMT).
The development came almost 12 days after the 60 tonnes of snubbing unit, flown in from Canada’s Calgary by the world’s largest cargo aircraft – Antonov An-24, reached the blowout site on November 4.
In August, OIL succeeded in capping the blowout well at Baghjan by installing BlowOut Preventer (BoP) on the wellhead after two failed attempts on July 31 and August 10.
However, the kill-the-well operation failed following the detection of leakage at the casing wellhead, and here’s when the global experts from M/s Alert Damage Control decided to move in for snubbing operation.
With the situation got complex with the new challenge ahead, the Canadian company Alert Damage Control tied up with Alberta-based Piston Well Services to move in its snubbing unit along with four crew members.
Meanwhile, in the process of dousing the fire, two firefighters and an electrical engineer lost their lives. The blowout has also affected the flora and fauna severely.
The major blowout occurred after the well suddenly became active while OIL was carrying out work-over operations in the gas-producing well Baghjan-5 under Baghjan Oilfield.
The well caught fire on June 9 and has been raging since then.
