ONGC makes steady progress RDS Wellsite Despite Environmental Challenges

New Delhi | 25 June 2025: Oil and Natural Gas Corporation (ONGC) today marked a critical milestone in its ongoing well control operations at the RDS site. With precision and coordination, the extra-long boom crane and a 40-ton crane successfully worked together to remove the 42 tubing stands from the derrick of the rig, clearing the path for the safe removal of the rig base from the wellhead.

Following the removal of the rig base, the next phase of operations involves dismantling the existing Blowout Preventer (BOP), followed by the installation of the capping stack. During this sequence, a temporary increase in gas discharge is anticipated. ONGC assures that the gas is non-toxic, and the volume is significantly reduced, presenting no risk to inhabitants residing beyond a 500-metre radius.
