TL;DR: Active CO2 reservoir management (ACRM) as mentioned in this paper combines brine production with CO2 injection to relieve pressure buildup, increase injectivity, manipulate CO2 migration, and constrain brine leakage.

TL;DR: The effect of elevated dissolved CO2 concentrations on compositionally and structurally distinct carbonate sample cores from the Weyburn-Midale CO2enhanced oil recovery and storage site (Canada) was measured from analysis of 3-D sample characterization and fluid chemistry data from core-flood experiments as mentioned in this paper.

TL;DR: In this article, the authors investigated the effects of aperture heterogeneity on flow pattern evolution in a single fracture in a low-permeability crystalline formation and developed a numerical model on the platform of GEOS to simulate the coupled thermo-hydro-mechanical processes in a penny-shaped fracture accessed via an injection well and a production well.

TL;DR: It is suggested that the simplest and most likely explanation for the observations is that a portion of the lower caprock was hydrofractured, although interaction with preexisting fractures may have played a significant role.

TL;DR: The ability to detect CO2 leakage from a storage reservoir to overlying dilute groundwater is dependent on CO2 solubility, leak flux, CO2 buoyancy, and groundwater flow, and simulations show that CO2 may not rise high enough in the aquifer to be detected.
