Tinsukia: Public sector giant Oil India Limited (OIL) has made a history by starting partial production from a blowout well under fire at Assam’s Tinsukia district on Monday, thereby achieving success in dousing the Baghjan blowout well fire for the moment by diverting the gas to the flare pit.

The development came almost three weeks after OIL's "kill the well" operation failed on August 18, a day after getting huge success in installing Blow Out Preventer (BoP) stack over the well head after two failed attempts.

Confirming the development OIL spokesperson Tridiv Hazarika said, the efforts to divert the gas has yielded results and the fire at the blowout well has been successfully doused for now.

"With this, we have started partial production by sending the natural gas to the Early Production System (EPS) at Baghjan."

"However, the success is yet not complete. We are still observing many other parameters to fully ascertain that the gas diversion efforts is fully successful," Hazarika said, adding, presently some gas has been diverted to two well site flare pits where the gas is being flared and some quantity of gas is being sent through two separate lines, from BoP through ground X Mass Tree, to Baghjan EPS for partial production.

It will likely take few more hours before we can call it a success, he added

Hazarika also said, the emphasis is not on production. "The purpose is to divert part of the gas so that snubbing operation becomes easier and present ordeal of local people due to sound and fire can be taken care off."

Highlighting the importance of the present strategy, Hazarika said, "Fall in gas pressure at well head will make snubbing operation easier."

Flare pit is an earthen pit excavated adjacent to drilling wells to vent and burn gas and oil produced from the well while snubbing operation is similar to well work over operation with a slightly different process.

Snubbing operation will be carried to kill the well at the bottom by inserting pipes and pumping mud through this new pipe.

The "blowout" occurred at the gas well number 5 at Baghjan oilfield, at a close proximity of Maguri-Motapung Beel and Dibru Saikhowa National Park, while work over operations was operations was going on to produce gas from new sand (oil and gas bearing reservoir) at a depth of 3,729 metres, leaving natural gas and condensate oil gush to hundred feet of in the air and spill all around. The well caught fire on June 9 and has been raging since then.

On August 18, OIL was inch away from killing the well when a valve on the casing pipe 13.3/8", just below the well head, got ruptured at the time kill fluid and chemical was pumped in to kill the well.
