State-owned Oil and Natural Gas Corporation (ONGC) on Saturday (June 21, 2025) said it has made "significant" headway in controlling the gas blowout at the Assam well, with flow rates reducing substantially.
The blowout — or uncontrolled flow of natural gas — took place on June 12 at a well of the Rudrasagar oil field of ONGC at Barichuk. A private firm, S K Petro Services, was operating the well on behalf of the company.

The international expert team from CUDD Pressure Control, USA, who arrived on site on Friday, has conducted a preliminary assessment of the situation and reviewed all actions undertaken by ONGC teams so far.
