Abstract
The Assam basin of India, it is the very where the first commercial oil in Asia was produced, at Digboi in 1889. After more than one hundred years of conventional oil production one would be interested to look at possibilities of other unconventional hydrocarbon resources such as shale gas and shale oil existent in this foreland basin. To assess HC potential of such unconventional a comprehensive estimation of Total Organic Carbon (TOC) over thick source rock shale zones is needed. In this study, TOC has been successfully calculated for the three main source rocks of the Assam Shelf area, Barail, Kopili and Sythet by application of the method □logR on well log data, which could be further used in assessment of HC potential in this basin.
