Oil India successfully caps kharsang well 76 after blowout

Oil India Limited (OIL) successfully capped Well KSG#76 at the Kharsang Oil Field (KOF) in Changlang district, Arunachal Pradesh, on November 22, 2025. This operation marks a major milestone following a blowout that occurred on October 30, 2025, during service operations, which resulted in an uncontrolled gas release from the well.

OIL's Crisis Management Team, with support from experts at Cudd Well Control, USA, and GeoEnpro Petroleum Limited, took over operations on November 1, 2025. The complex task involved safely removing the damaged Blowout Preventer (BOP) and installing a pre-positioned capping stack, which effectively redirected and contained the gas flow, leading to the successful closure of the well.

This achievement highlights OIL's engineering expertise and strong collaboration with global specialists and local teams. The company expressed gratitude to the District and State Administration of Arunachal Pradesh, the Ministry of Petroleum & Natural Gas (MoPNG), and the local community for their support in the timely execution of this high-risk operation.
