US Team to Cap ONGC Well in Assam’s Sivasagar: A Safe Resolution in Sight

On June 20, 2025, Assam Chief Minister Himanta Biswa Sarma announced that a team of expert engineers from the United States has arrived in Sivasagar district to address a critical gas leak at the Oil and Natural Gas Corporation’s (ONGC) RDS-147A well. The situation, which has persisted for nine days since the blowout on June 12, has raised environmental and safety concerns due to its proximity to a river embankment. With the arrival of the US team to cap the ONGC well, hope is on the horizon for a swift and secure resolution.

The Gas Leak Crisis in Sivasagar

The uncontrolled gas leak at ONGC’s Rudrasagar oil field in Barichuk, Bhatiapar, has been a pressing issue for Assam. The blowout, which began over a week ago, has prompted urgent action from both the state and central governments. Chief Minister Sarma emphasized the potential danger, noting that a fire at the site could lead to a major disaster, especially given the well’s location near a river embankment. The stakes are high, as any escalation could threaten local communities and the environment.

ONGC has been working tirelessly to control the gas discharge, but initial efforts, including “junk shot” operations to block the flow with heavy materials, have proven unsuccessful. The company has now shifted to a more practical and safer strategy, dubbed “Plan C,” which involves permanently capping the well. This approach requires specialized expertise, prompting ONGC to enlist international support.

US Team to Cap ONGC Well: A Game-Changer

The arrival of the US team to cap the ONGC well marks a significant step forward. These experts, known for their advanced blowout control capabilities, reached Sivasagar on the evening of June 20, 2025. Full-scale operations to seal the well are set to begin on Saturday, June 21. According to Chief Minister Sarma, nearly 50% of the groundwork, including site preparation and equipment mobilization, has already been completed, paving the way for the team’s efforts.

The involvement of international specialists underscores the complexity of the situation. ONGC has explored multiple strategies to contain the leak, but the high-pressure gas discharge has proven challenging. The US team’s expertise is expected to provide critical insights and technical support, boosting confidence in a successful outcome.

Government and ONGC’s Coordinated Response

Both the Government of India and the Government of Assam are monitoring the situation around the clock. Chief Minister Sarma has been in close communication with Union Petroleum Minister Hardeep Puri, urging ONGC to expedite containment efforts. The state government’s proactive stance reflects its commitment to protecting local residents and preventing environmental damage.

ONGC, in coordination with district authorities, has taken several measures to ensure safety. Approximately 1,500 people from nearby areas have been evacuated as a precaution, and the company is providing financial aid and support to affected families. Additionally, ONGC has intensified ambient air quality monitoring, with all parameters, including particulate matter and gas concentration, remaining within permissible limits. The construction of an alternate access road has also been initiated to facilitate safer movement of personnel and equipment around the well site.

Environmental and Community Concerns

The gas leak has sparked significant concern among local residents, who fear the potential consequences of a prolonged incident. The 2020 Baghjan blowout, which lasted over five months and caused widespread environmental damage and displacement, looms large in public memory. However, experts note that the Sivasagar incident is less severe, and ONGC’s swift response, coupled with international expertise, aims to prevent a similar catastrophe.

The well’s proximity to a river embankment adds another layer of urgency. A flood or fire could exacerbate the situation, threatening both the environment and nearby communities. ONGC’s commitment to environmental safety is evident in its continuous monitoring and efforts to minimize risks. The company has assured the public that it is prioritizing the safety of the local community and the ecosystem.

A Step Toward Energy Security

The Sivasagar incident highlights the inherent risks of oil and gas exploration, particularly in high-pressure operations. Blowouts, while rare, underscore the need for robust response mechanisms to ensure operational safety and energy security. ONGC’s collaboration with international experts demonstrates the importance of global cooperation in addressing such challenges.

Chief Minister Sarma’s leadership has been instrumental in coordinating efforts and keeping the public informed. His updates, shared via social media and press conferences, have provided transparency and reassurance. The involvement of the US team to cap the ONGC well is a testament to the government’s and ONGC’s commitment to resolving the crisis efficiently.

Looking Ahead: A Hopeful Resolution

As the US team prepares to begin capping operations, there is cautious optimism in Sivasagar. The groundwork laid by ONGC, combined with the expertise of international specialists, sets the stage for a successful resolution. The focus now is on executing the capping process safely and swiftly to restore normalcy and protect the region from potential harm.

The incident serves as a reminder of the challenges inherent in the energy sector and the importance of preparedness and collaboration. With the US team to cap the ONGC well, Assam is poised to overcome this crisis, reinforcing its resilience in the face of adversity.

Conclusion

The arrival of the US team to cap the ONGC well in Assam’s Sivasagar is a beacon of hope for a region grappling with a critical gas leak. Chief Minister Himanta Biswa Sarma’s proactive leadership, coupled with ONGC’s determined efforts and international support, signals a path toward a safe and swift resolution. As operations commence, the people of Assam await a positive outcome, confident that the combined expertise and resources will bring this challenging chapter to a close.
