Surat: Twelve persons were injured on Saturday when an ONGC’s gas well near Olpad town caught fire during a repair operation. Four of the injured are in a serious condition, fire brigade officials said.

ONGC in a statement said, “While three of them have already been discharged after first aid, all necessary medical treatment is being given to others."

The incident occurred when a blow-out preventer (BOP), which is installed on wells to prevent a fire, was being repaired at a well in OLPAD-31 in Ankleshwar basin, ONGC’s Ankleshwar asset manager Har Govind said. The injured, he said, have been rushed to a hospital in Surat. A blowout occurred as the well got activated during repair of the BOP, he said. “The fire has been contained and kept to cool, that is to say it is being allowed to burnout."

Those injured include 2-3 contract workers and the rest are ONGC’s crisis management employees.

“It is a major fire, and we rushed to the spot with our equipment, but we are unsure of how to control it. We have to remain 500 metres away from it due to heat generation," a fire brigade official said.

The company said it mobilized its crisis management team and all resources to control the fire, which broke out on Saturday around 12.30pm in an onshore well in Olpad area 80km away from Ankleshwar, during repair and maintenance job. PTI
