Hindustan Petroleum says HOECL’s crude hit Mumbai refinery ops, to seek damages

Hindustan Petroleum Corporation (HPCL) on Monday said its Mumbai refinery faced operational issues, including corrosion in downstream units, after processing crude oil from the Hindustan Oil Exploration Co.’s (HOECL) B-80 Mumbai Offshore oil field.

The company said it had sourced 54.6 million tonnes of crude oil from the B-80 Mumbai Offshore oilfield of HOECL, for processing at its Mumbai Refinery through auction dated 25.08.2025.

"A part of the said crude oil received subsequently was processed in October 2025 and found to be causing operational issues including corrosion in downstream units, yielding suboptimal

outputs and turned down production," said HPCL, adding that potential reasons are the very high salt and chloride content in the crude oil, which are beyond contractual terms of Crude Offtake Sales Agreement
with supplier.

"Matter has been taken up with the supplier and claims and damages in line with the contractual terms would be pursued," HPCL said.

The company has taken the necessary steps to return to normal operations at the earliest, it added.

On Monday, HPCL's scrip ended at Rs 454, up 3.51% while HOECL’s scrip ended at Rs 161.95, down 0.64%, on the BSE.
