Abstract

The study area is in the Bikaner Nagaur Basin in Rajasthan which essentially is a lower Paleozoic basin with a thin young sediment cover. Heavy oil has been discovered in the sandstone and carbonate intervals in the Paleozoic section. The sandstone interval is the most prolific hydrocarbon interval and is characterized by interbedded sandstone, siltstone and shaly layers having good porosity. The objective of the study was to carry out detailed reservoir characterization of a 50 sq km area surrounding one of the recent discovery wells and also comprising some of the interesting structural prospects.
