India’s state-controlled Oil & Natural Gas Corporation (ONGC) has started the search for a well stimulation vessel (WSV), a seeking long-term charter for its west coast operations.

Two people with direct knowledge of the bid process said ONGC recently floated enquiries to charter the WSV for a nine-year term, with the vessel likely to be mobilised next year, following a tender process.

"ONGC has just issued expressions of interest for the WSV and a formal tender is likely to be floated later this year, based on the interests received," one person said.
