New Delhi: State-owned Oil and Natural Gas Corporation (ONGC) is making efforts to contain an uncontrollable release of natural gas from a well in Assam's Sivasagar district, saying a crisis management team is laying out equipment to bring the well under control. "Efforts are underway to control the continuous gush of gas from the RDS#147A near Bhotiapar in the Rudrasagar field, located in the Sivasagar District," the company said in a statement.

On June 12, around 11:45 AM, during servicing operations at Well No. RDS-147, gushes of gas were observed from the well. There was, however, no fire or injuries. Upon detection, ONGC immediately activated standard safety protocols. The site was promptly secured, and an emergency response team led by the Asset Manager reached the location without delay.
