ONGC caps Mori-5 well in five days, brings blowout under control
State-owned Oil and Natural Gas Corporation (ONGC) has successfully established well control at its Mori-5 well in Andhra Pradesh, completing the capping operation in a record five days, the company said on Saturday.
The Mori-5 well, located in ONGC’s onshore asset in Andhra Pradesh, experienced a blowout on January 5, 2026, during routine service operations being carried out by contractor Deep Industries Ltd. The incident occurred when the well was temporarily under service, leading to an uncontrolled release of hydrocarbons.
ONGC activated its crisis management protocols immediately, suspended all related operations in the area, and mobilised specialised well-control teams and equipment to contain the situation.
No fatalities were reported, and the company maintained that safety and environmental protection were prioritised throughout the response. In a Statement, ONGC said it “has successfully established well control at Well Mori-5, completing the capping operation in a record time of five days, marking a significant achievement in blowout response and operational excellence.” With the successful capping of the well, ONGC said field-level operations related to the Mori-5 incident have been concluded and no further operational updates are expected, it said.
ONGC reiterated its commitment to safety, environmental protection and operational discipline across its oil and gas operations.
