India’s upstream push gathers momentum.

ONGC and Oil India Ltd will launch a ₹3,200 crore stratigraphic drilling campaign in untapped offshore areas next year. This represents a major step towards discovering new hydrocarbon reserves and reducing import dependence.

ONGC and Oil India Ltd (OIL) are set to launch a ₹3,200 crore stratigraphic drilling campaign in early 2026 to explore untapped offshore hydrocarbon reserves and reduce India's import dependency.

The initial phase will involve drilling four deepsea wells in the Andaman, Mahanadi, Saurashtra, and Bengal sedimentary basins. BP will provide technical expertise for site identification and drilling operations.

Stratigraphic drilling focuses on analysing subsurface geological formations to assess potential hydrocarbon resources without immediate extraction.
