India’s Oil & Natural Gas Corporation (ONGC) has floated multiple offshore seismic tenders as it steps up its hunt for oil and gas resources.

Two sources familiar with the development said the state-controlled company is in the market to select its preferred bidders for specialised seismic campaigns across a number of basins.

The first tender calls for conducting a highly specialised 4C-3D OBN (ocean bottom node) seismic data acquisition drive on ONGC’s Mumbai High South field during the upcoming field season, one source said.
