Enhancing Oil Recovery Techniques and Their Impact on Production Efficiency(An Applied Analytical Study on the Iraqi Oil Sector)

Abstract

Generally, enhanced oil recovery (EOR) techniques are paramount in improving the efficiency of oil production, particularly in mature and declining oil fields, which suffer from limited primary and secondary recovery technologies. Thus, this paper discusses the critical EOR models, thermal, chemical and gas injection methods and their impact on recovery factor and reservoir performance with the efficiency output. It showcases some of the technological tools used by EOR to decrease oil viscosity, elevate sweep efficiency, and retain pressure in the reservoir. From its theoretical and practical nature, it examines details about reservoir conditions, fluid types and field engineering for the preference or use of methods and procedures for EOR. It also shows that with correct and methodical implementation of the EOR techniques there can be a large recovery of the reserves and the life and production rates are to be improved at field level. Ongoing EOR procedures should be accompanied by a comprehensive reservoir management as it is claimed that efficient usage of oil production and the long-term sustainable use of oil resources can be achieved through these combination.
