            2.3.11 CHHATTISGARH BASIN

            Chhattisgarh  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.

            The elements of petroleum system in the basin
            are largely speculative.

            Entire  Proterozoic  sequence  of  the  basin  has
            been considered as a single Proterozoic Play and
            sub-divided into four assessment units based on
            geological rationales.
