68 INDIA'S HYDROCARBON OUTLOOK 2024-2025

2.3.18 BASTAR BASIN

Bastar is a Category III basin with entirely undiscovered in-place, that calls for intense exploration for
a potential discovery.

The basin overlaps with the state(s) of Chhattisgarh, Odisha.

Bastar Basin, one amongst the several
Proterozoic sedimentary basins is located over
Peninsular India. The elements of petroleum
system in the basin are largely speculative.

Entire Proterozoic sequence of the basin has
been considered as a single play, sub-divided by
a fault into two assessment units.
Paleo-to-Meso-Proterozoic Basuhari-Rohtas play
of Vindhyan Basin has been used in the analogue
study. Assessment of thickness of sedimentary
sequence is the focus area.

• Hydrocarbon prospectivity and Basin
maturity:

In the basin, 1 play is known within Pre-Cambrian.
Aerial Yield method was used on analogy of
Vindhyan Basin.
Bastar basin has a total hydrocarbon in-place of
1 MMTOE and this is entirely undiscovered risked
in-place.

• Basin datasets and studies:
As of 31.03.2025, there is no seismic/well data
available at NDR.
