Abstract

Akholjuni, an emerging field of Cambay basin, lies north of Mahisagar cross-fault which separates the tectonic blocks of Cambay-Tarapur and Broach. At the base of Babaguru formation, the most prolific producer in the area, Miocene Basal Sand (MBS) is situated. With an average sand thickness of around 20m, the production history of wells studied for MBS has been quite intriguing when viewed in respect of entrapment and facies where structurally low wells have produced good amount of hydrocarbon and structurally higher wells have produced water even though these are envisaged to be part of a single corridor. In light of these challenges an effort has been made to understand the correlativity of MBS, sand dispersal pattern, facies variation and entrapment condition. Core study, NMR data and log correlation along with seismic was used as input in the study.
