Huge India oil well fire extinguished after five months

A massive oil well fire that has raged for more than five months in northeast India has finally been extinguished, officials said Sunday.

Oil India engineers had battled the blaze in Assam state since an explosion in June, weeks after the well blew out and began discharging huge quantities of natural gas.

Two employees of the state-owned company died in the blast, which sent a wall of flame and massive plumes of smoke into the sky. A third worker died in September after an accident at the site.

Experts from Singapore, the United States and Canada joined efforts to contain the inferno, and Oil India spokesman Tridiv Hazarika said Sunday the fire had now been "doused completely".

"The well has been killed with brine solution and is under control now," he told AFP, adding that the well had yet to be capped.

"There is no pressure in the well now and it will be observed for 24 hours to check if there is any amount of gas migration and pressure build-up," Hazarika said.

Thousands of villagers in Tinsukia district had been relocated to relief camps after the blaze started.

The Baghjan oil field is next to the Dibru-Saikhowa National Park and the wetland habitat of several endangered species, including tigers and elephants.

The region is also home to several bird sanctuaries.

The Wildlife Institute of India said in a July report that the oil spill had brought a "large-scale impact" on local plant and animal life.

"The toxins released are known to have long-term persistence in soils and sediments, which will not only affect current life conditions, but due to sustained release over a long period, pose a serious health risk for a longer term," the institute added.

The disaster cost Oil India more than $800,000 according to the firm's estimates, managing director Sushil Chandra Mishra told local media in late September.
