BASIN MODELLING STUDIES OF THE NORTH AND SOUTH ASSAM SHELF REGION

Abstract

The North and South Assam Shelf is one of the well-explored regions in India with lots of geological and geophysical data available chiefly because of the hydrocarbon exploration in the region. Different workers have done extensive petroleum systems modelling in these regions. For some further study purposes, a region has been chosen in the South Assam Shelf for the basin modelling purpose .where there are only fewer modelling activities been conducted till date. Only fewer wells in the region have oil/gas signatures. So the study can give any new results regarding the hydrocarbons findings. However, the extensive basin modelling study conducted on one such section of 33 kilometres which also advances into the deeper regions of the Naga Thrust along with the geochemical data from the surrounding wells, shows that although there is enough of organic matter in the region, but there isn't any enough of the cooking conditions to generate and expel the petroleum from its pores. So from this study it is confirmed that the region selected in the South Assam Shelf, has little or almost no potential to generate the hydrocarbons. This study also concurs with the findings of the previous workers who have studied the surrounding areas of the same region in South Assam Shelf.
