Performance Analysis of Advanced Wells in Reservoirs Using CO2 Enhanced Oil Recovery; Simulations and Cost Estimation

Abstract

This thesis encompasses the study of advanced wells applications in reservoirs using immiscible CO2 for enhanced oil recovery. The goal of this thesis is to analyze the performance of advanced wells in different simulated reservoir conditions and figure out the suitable option with high performance ability and cost effectiveness for real life implementation. The research begins with a detailed literature review of the methods, mechanisms, and fundamental parameters related to immiscible CO2 enhanced oil recovery. The literature review further explains the types and working principles of different advanced wells. The succeeding chapter contains the reservoir model, well model and simulation cases. The details of the parameters and completion scenarios has been documented in the chapter. With varying parameters, the difference in the oil recovery performance and impact on it by different advanced wells was assessed. The outcome of the computer aided simulations demonstrates that the oil recovery is heavily depend on the permeability and injection rate of CO2 in the reservoir. Furthermore, AICVs have been seen to have better performance in terms of oil extraction and cost effectiveness
