Abstract

Natural hydrocarbon seepages detected in Cauvery offshore area are associated with NE-SW trending faults that are connected to a source area suggesting that these faults act as a conduit for migration. These seepages also show a positive correlation with hydrocarbon bearing wells indicative that same system might lead to an area of accumulation with the seepages acting as markers. Based on this model, seepages had also been delineated in shallow and deep Palar offshore which share a similar tectonic history. These seepages are also found to be associated with NE-SW faults connected with source Sriperambudur Formation. Based on this, prospective areas could be delineated for further exploration.
