A review of the current progress of CO2 injection EOR and carbon storage in shale oil reservoirs
TL;DR: In this paper, the authors comprehensively reviewed the CO2 injection enhanced oil recovery (EOR) and carbon storage related literature in shales over the past decade, including description of major shale reservoirs producing oil, selection of injection scheme, models applied to simulate gas injection, oil recovery mechanisms for different types of gas, molecular diffusion and its laboratory measurement, nanopore effect, adsorption effect on carbon storage and transport, laboratory work of gas injection in shale cores, pilot tests, and economic evaluation.

A simple permeability model for shale gas and key insights on relative importance of various transport mechanisms
TL;DR: In this article, an apparent permeability model of shale based on a unified diffusion coefficient that transforms its value per the flow regime, including the effect of molecular diffusion, viscous flow, and surface diffusion of adsorbed gas through linear superposition is proposed.

TL;DR: In this paper, the effect of CO2-water exposure on the micro-structural alteration in shale was investigated and the results indicated that supercritical CO2 (10 MPa, 14 MPa) was more significant than sub-critical CO 2 (6 MPa), which reflected that the roughness and complexity of pore structure and morphology in shale decreased.

Investigations of CO2 storage capacity and flow behavior in shale formation
TL;DR: In this article, the authors comprehensively evaluated CO2 storage potential and injectivity in the Bakken Formation through various approaches, and several novel conclusions were obtained regarding analyzing main control factors; the most important one is that adsorption outweighs molecular diffusion in determining CO2 injection rate.
