Dibrugarh : Oil India Limited (OIL) has successfully completed the capping operation at Well KSG#76 in the Kharsang Oil Field, operated by GeoEnpro Petroleum Ltd (GEPL) in Arunachal Pradesh's Changlang district.
The blowout occurred on 30 October 2025 during service operations, causing an uncontrolled gas release.
OIL’s Crisis Management Team (CMT), with support from Cudd Well Control, USA, and GEPL, took charge on 1 November and began safely removing the damaged Blowout Preventer (BOP) from the wellhead.
After the BOP was removed, the pre-positioned capping stack was installed on the wellhead, successfully redirecting and containing the gas flow.
Once secured, the BOP was closed, stopping the gas discharge from Well KSG#76.
OIL credited the operation’s success to careful planning, technical expertise, and strong collaboration between global specialists and local teams.
The company thanked the Arunachal Pradesh administration, the Ministry of Petroleum & Natural Gas, and the local community for their support.
OIL affirmed its commitment to safe, sustainable, and efficient operations while proceeding with the next phases of the well control roadmap.
