5.1 Implementation of PRMS for
Standardized Hydrocarbon Resource
Reporting in India

To ensure consistency, transparency, and
international alignment in hydrocarbon
resource estimation, the Directorate General
of Hydrocarbons (DGH) has initiated a periodic
update of the country-level database on oil
and gas reserves and resources. This update is
conducted in accordance with the Petroleum
Resources Management System (PRMS)
standard, and applies across all operating
regimes-both Nomination and Contract.
