CO2 enhanced oil recovery: a catalyst for gigatonne-scale carbon capture and storage deployment?

A Pore Scale Evaluation of Produced Biosurfactants for Ex-situ Enhanced Oil Recovery

Microbial enhanced oil recovery (MEOR) is an economical method used to improve the oil recovery from reservoirs. In the MEOR techniques, by applying different microorganisms, a variety of products such as bioacid, biogas, biosurfactant, and biopolymer are generated, among which biosurfactant, one of the important metabolites, is produced by bacteria. It is worthy to note that bacteria are suita...

Increasing CO2 Storage in Oil Recovery

Carbon dioxide (CO2) injection has been used as a commercial process for enhanced oil recovery (EOR) since the 1970’s. Because the cost of oil recovered is closely linked to the purchase cost of the CO2 injected, considerable reservoir engineering design effort has gone into reducing the total amount of CO2 required to recover each barrel of oil. If, on the other hand, the objective of the CO2 ...

An Experimental Study of Surfactant Alternating CO2 Injection for Enhanced Oil Recovery of Carbonated Reservoir

Core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating CO2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. The core samples were provided from a low permeability mixed wet oil reservoir at 156 °F and 1900 psia. In addition, very few studies of surfactant adsorption on car...

Returns to Scale in Carbon Capture and Storage Infrastructure and Deployment

The degree to which carbon capture and storage (CCS) is deployed will be partly determined by the returns to scale of the technological system that captures, transports, and stores carbon dioxide (CO2). This technological system spatially connects the organization of CO2 point sources with the organization of geologic CO2 storage reservoirs. These point sources and storage reservoirs are hetero...
