Abstract

We performed rock physics modeling and simultaneous inversion of multiple seismic angle stacks with an objective to map the spatial extent of heavy oil bearing Jodhpur sands in Baghewala structure of Bikaner-Nagaur basin. We built a rock physics model from measured acoustic and shear information from offset wells and used the model to predict shear sonic data in four wells inside the area of study. We further used the inverted acoustic and shear impedances to predict seismic litho-facies and associated probabilities under a Bayesian framework. The reservoir property maps derived from inverted seismic data conform to the geological setting of the area.
