Abstract
A comprehensive analysis of the CO2 Huff-n-Puff process with application to representative light oil system contained within a fractured porous media is present in this article. To accomplish this work, a simulation model representative of the laboratory experimental model was built and constrained under similar laboratory conditions. Six sets of CO2 Huff-n-Puff experiments were conducted at injection pressures of 1723–10342 kPa; moreover, additional sensitivity analysis was performed on the 5170 and 6894 kPa conditions for different permeability and porosity. Results of this study demonstrate that cyclic injection of CO2 under miscible conditions performs more favorably than under immiscible injection conditions.
