Abstract

Bhogpara and Nahorkatiya oil fields are the depleted and matured oil fields of Upper Assam Basin. The recoveries of oil in these fields are getting decreased day by day as conventional methods are unable to recover more oil. The demand for using an unconventional method becomes an attractive option for the matured oil fields. For using unconventional methods like enhanced oil recovery requires a proper characterization of porous media. Characterization and determination of rock properties are the key factors for managing and enhancing oil recoveries. This paper deals with porous media characterization of Bhogpara and Nahorkatiya oil fields of Upper Assam Basin to determine the applicability of enhanced oil recovery techniques for improving its oil recovery rate. The rock characterization was done by carrying out Petrographic analysis, Sieve analysis, and Porosity & Permeability determination. The various analysis of porous media of Bhogpara and Nahorkatiya oil fields shows that they are good candidates for enhanced oil recovery processes.
