ONGC Chairman and Managing Director Dinesh K Sarraf along with Director-Onshore Ashok Varma are camping at the site to supervise the work.
"Looking at the situation, we believe that it will take at least 15 days to control the fire," Varma told reporters.
According to a statement issued by ONGC, seven fire tenders have been deployed at the site, along with two trailer pumps. One more fire tender is being mobilised today from Gandhar. This apart, high discharge water pumps are being mobilised from Vadodara and Rajahmundry.
ONGC said it has sought help of globally renowned oil and gas blow out control experts Boots & Coots from the US to control the blaze. They are expected to arrive at the site by tomorrow.
Meanwhile, ONGC's crisis management team (CMT) has stepped up efforts to drill a relief well at a nearby place for which the foundation work has already been started.
At least 12 ONGC employees had received burn injuries in the incident. While five of the injured have been discharged from hospital, seven others are still undergoing treatment, officials said.
Varma said farmers, whose farms are located near the well and crops were damaged in the incident, will be given a compensation. "ONGC will give appropriate compensation to farmers who have suffered damages due to fire," he said.
