New Delhi: Oil and Natural Gas Corporation Limited (ONGC) has commissioned a 200-tonne crane with an 80-metre boom at the site of well RDS#147A in Assam’s Rudrasagar field, the company said on Tuesday. "This marks a significant advancement in the preparatory phase leading to the well-capping operation," a statement issued by ONGC said. The oil major said that it "continues to make measured and strategic progress in the well control operations at RDS#147A, despite persistent rainfall and challenging site conditions."
The crane is now fully operational and is actively supporting critical tasks at the site. Its deployment follows extensive stabilisation work to ensure safe use amid persistent rainfall and challenging ground conditions.
“Several site stabilisation and preparatory activities were undertaken to ensure the safe deployment and operation of the heavy-duty crane,” ONGC said. “ONGC teams responded promptly, reinforcing the location to maintain momentum in the ongoing operations,” it added.
With the Dikhow River swelling due to heavy rain, ONGC’s Regional Crisis Management Team has relocated its critical water pump system to higher ground to maintain uninterrupted water blanketing — a key safety measure being conducted round-the-clock.
“Water blanketing continues around the clock as a key safety protocol,” the company said.
Gas composition analysis conducted on June 24 shows that the discharge is approximately 97% methane, ONGC said, confirming that the gas remains within manageable and safe limits, with no immediate risk to surrounding habitations.
The company said it is working in close coordination with international well control experts and district authorities to bring the situation under full control.
“ONGC remains committed to executing all well control measures with the highest standards of safety, technical rigour, and environmental responsibility,” the statement added.
