Abstract

Integration and analysis of all the available geoscientific data in Jabera-Damoh area of Son Valley, Vindhyan Basin have been carried out to evaluate hydrocarbon prospects. Taking lead from the rank exploratory well, time structural mapping over the area with the help of seismic data has established a southeasterly extension of Damoh structure, north of Jabera. The structure is bounded by two major NW-SE trending faults whereas ENE-WSW trending faults are more dominant in Jabera dome, in close proximity to the Son-Narmada Lineament. Tectonic inversion has affected Jabera structure mainly from Kajrahat Limestone member of Semri Group onwards. Seismic facies and interval velocity analysis supported by paleocurrent data suggest better development of reservoir facies towards north i.e. in the area around Damoh. Further exploratory efforts should be pursued by exploring Damoh structure and acquiring additional seismic data in the eastern and southwestern Part of this Category III basin.
