The fire in an oil well of the Oil and Natural Gas Corporation (ONGC) in Surat continued to rage for the third day on Monday.
Fire tenders have been struggling to douse the massive blaze that broke out on Saturday afternoon following an explosion in the well due to leakage in gas pipeline.
Senior officials of ONGC including its Chairman, Dinesh K Sarraf, visited the accident site on Monday and took stock of the situation.
The fire had left 12 people injured. A tower near the well was reduced to ashes on Sunday as fire tenders toiled to put off the blaze.
An investigation into the incident is on. It could take 20-25 days to douse off the flames, sources said. A two-member team from the U.S. is also expected to assist in putting off the fire.
This is the third incident of fire to be reported from the site this year.
