Guwahati, August 20: The team of blowout well killing exerts from Oil India Limited (OIL) have started preparing the ground for making a renew attempt to kill the blowout gas well in Baghjan oil field in Tinsukia district.
The well killing operation had to be aborted two days back even after placing on the blowout preventer (BOP) on the well head.
“Heat shields installed over BOP stack to protect from excessive heat. Repairing/modification job of damaged casing head housing is in progress. Once the modification arrangement is completed, cement dumping to casing annulus will be carried out. All cementing equipment and material are being mobilised. Kill lines have been made ready for cement ‘pack off’ job,” a OIL communique informed on Friday.
Well killing operations would be attempted once these jobs are completed. All safety precautions are in place and the wellhead, BOP stack, choke manifold & ground x-mas tree are being continuously sprayed with water for cooling purpose. All efforts are being taken to control the well at the earliest, according to an OIL official.
Meanwhile, oil and gas production still continues to be affected due to forceful closure of few oil & gas wells connected to Baghjan EPS. Drilling and workover operation also continue to be affected at few of the locations due to forceful closure of operation.
