TL;DR: In this article, a coupled reservoir-well simulation scheme is established to analyze quantitatively multi-phase fluid flow and heat transport due to carbon dioxide (CO2) injection in a reservoir rock-injection well system and to evaluate rigorously the CO2 injection efficiency in terms of the CO 2 injection rate and injectivity.

TL;DR: In this paper, a series of probabilistic evaluation is performed sequentially using three-dimensional geologic modeling and grid-based Monte Carlo simulation as a linked methodology to estimate multi-fluid-phase (i.e., individual gas-, liquid-, supercritical-, and whole fluid-phase) CO2 storage capacities of the target clastic saline formations in the Pohang Basin, Korea.

TL;DR: In this paper, the authors discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two phase displacement processes in porous media and show that replotting the data against a novel macroscopic capillary number resolves the problem for discontinuous mode displacement.
Abstract: We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves contradicts the theoretically predicted force balance. We show that replotting the data against a novel macroscopic capillary number resolves the problem for discontinuous mode displacement.

TL;DR: In this paper, the storage mechanism method was used to estimate the CO2 storage capacity of the Ordovician Majiagou Formation in order to give data support for GCS project in the Ordos Basin.
Abstract: Geologic CO2 storage (GCS) is one of the preferred solutions to reduce greenhouse gas emissions. Comparing with other geological reservoirs, the deep saline aquifers have huge storage potential and currently the most promising one. Since technical and economical viability of geologic CO2 storage depends highly on the CO2 storage capacity, this paper mainly uses the storage mechanism method to estimate the CO2 storage capacity of the Ordovician Majiagou Formation in order to give data support for GCS project in the Ordos Basin. The results show that the total effective CO2 storage capacity of the deep brine layer of the Ordovician Majiagou Formation in the Ordos Basin is 15.98-109.22Gt. The Majiagou Formation has sufficient storage capacity to accommodate decades of CO2 emissions generated by multiple coal-fired power plants in the Ordos Basin. For CO2 geological storage, the structural trapping mechanism contributes the largest amount of CO2 storage, and the amount of CO2 storage contributed by the two mechanisms of bound gas trapping and solubility trapping is almost negligible. The above results provide methods and references for CO2 estimation of GCS project in this region, and provide data support for the site selection and injection of CO2 sequestration in deep salt layers of the Ordos Basin.
