Abstract

The accelerated exploration activities within the Damoh-Jabera-Katni PEL block, Son Valley has led to establishing the Rohtas and Kaimur as gas plays within the Lower and Upper Vindhyan sediments respectively. Recently, an exploratory well (D), was targeted to explore the wedge out prospects within the Rohtas Limestone as well as the deeper Mohana Fawn Limestone. The conventional testing of an object in Mohana Fawn Limestone for the first time in this area led to the discovery of a new gas play. Integration of well and seismic data shows extension of the gas pool over a large area within the exploration acreage of Son Valley. The discovery has opened up new dimension in the exploratory successes in the Proterozoic Vindhyan Basin points towards the possibility of a separate CharkariaMohana Fawn Petroleum system in addition to the shallow Rohtas-Rohtas-Kaimur petroleum system in the area.
