CT&F Journal dedicates this special issue, including relevant Colombian and international (Argentina, Canada, Norway, and the U.S) studies describing different EOR technologies and methods addressing topics of interest for the oil and gas community. This special edition includes ongoing research in SmartWater technology and a practical methodology for interwell water tracer programs. This volume also contains a numerical simulation study of CO2-EOR based on produced CO2 enriched using Oxycombustion providing an overview of the integrated vision of EOR and the reduction of carbon footprint. In this issue, Thermal EOR methods include downhole heating technologies (DHHT) and a numerical simulation study evaluating different strategies combining DHHT and hybrid cyclic steam methods considering its evaluation based on oil recovery, energy efficiency, and environmental indexes. Finally, research studies on Chemical EOR (cEOR) are included in this volume focused on advanced chemicals tolerant to high temperature (i.e., AMPS) and mechanical degradation (i.e., biopolymer and polymeric surfactants). A comprehensive review of the use of nanoparticles to improve the thermal resistance of synthetic polymers was also included as an alternative approach to enhance the performance of EOR polymers. Studies related to the mechanical degradation of polymers are complemented with papers describing experimental and CFD simulation methodologies contributing to the design of cEOR in Colombia.
Both CT&F and Ecopetrol hope to continue promoting and contributing to developing a network of professionals and knowledge dissemination integrating EOR and energy transition areas in years to come.
