Commentary

The basin remains active, with ONGC leading development and new entrants competing for acreage. The 2025 amendment to the Oilfields Act, larger OALP rounds and improved gas pricing address long-standing investor concerns, although the regulator remains slow. Outlook: Neutral.

Description

The Basin dates from the late Cretaceous to Holocene with thick sedimentary fill ranging from 1 to 5km thick. While the basin has been widely explored, there remains some question over some of the structural elements, most notably whether a Mesozoic synrift sequences (as indicated by the recently acquired seismic data), are a dominating feature when considering oil & gas exploration.

Summary

While the Basin has been developed, there remains considerable prospectivity. Initial discoveries were made in Miocene limestone reservoirs, subsequent discoveries have demonstrated the viability of alternative play concepts.
