The geological storage of carbon dioxide (CO 2 ) is a well-studied technology, and a number of demonstration projects around the world have proven its feasibility and challenges. Storage conformance and seal integrity are among the most important aspects, as they determine risk of leakage as well as limits for storage capacity and injectivity. Furthermore, providing evidence for safe storage is critical for improving public acceptance. Most caprocks are composed of clays as dominant mineral type which can typically be illite, kaolinite, chlorite or smectite. A number of recent studies addressed the interaction between CO 2 and these different clays and it was shown that clay minerals adsorb considerable quantities of CO 2 . For smectite this uptake can lead to volumetric expansion followed by the generation of swelling pressures. On the one hand CO 2 adsorption traps CO 2 , on the other hand swelling pressures can potentially change local stress regimes and in unfavourable situations shear-type failure is assumed to occur. For storage in a reservoir having high clay contents the CO 2 uptake can add to storage capacity which is widely underestimated so far. Smectite-rich seals in direct contact with a dry CO 2 plume at the interface to the reservoir might dehydrate leading to dehydration cracks. Such dehydration cracks can provide pathways for CO 2 ingress and further accelerate dewatering and penetration of the seal by supercritical CO 2 . At the same time, swelling may also lead to the closure of fractures or the reduction of fracture apertures, thereby improving seal integrity. The goal of this communication is to theoretically evaluate and discuss these scenarios in greater detail in terms of phenomenological mechanisms, but also in terms of potential risks or benefits for carbon storage.

“…For example, up to around 171 billion tonnes of CO 2 can be stored in the Marcellus Shale in the Appalachian Basin [38] and up to around 28 billion tonnes in the Devonian shales in Kentucky [36]. According to the prediction of Liu et al [102] based on reservoir modelling, around 4 × 10 4 tonnes of CO 2 can be injected through each horizontal well into the New Albany Shale play with less than 1% breakthrough, of which 95% of the CO 2 can be sequestrated in the shale play. Therefore, the use of a greenhouse gas such as CO 2 in the hydro fracturing process will assist in protecting the environment by reducing the greenhouse gas effect and will also lead to additional shale gas production enhancement.…”

Characteristics of Clay-Abundant Shale Formations: Use of CO2 for Production Enhancement

et al. 2017

Clay-abundant shale formations are quite common worldwide shale plays. This particular type of shale play has unique physico-chemical characteristics and therefore responds uniquely to the gas storage and production process. Clay minerals have huge surface areas due to prevailing laminated structures, and the deficiency in positive charges in the combination of tetrahedral and octahedral sheets in clay minerals produces strong cation exchange capacities (CECs), all of which factors create huge gas storage capacity in clay-abundant shale formations. However, the existence of large amounts of tiny clay particles separates the contacts between quartz particles, weakening the shale formation and enhancing its ductile properties. Furthermore, clay minerals' strong affinity for water causes clay-abundant shale formations to have large water contents and therefore reduced gas storage capacities. Clay-water interactions also create significant swelling in shale formations. All of these facts reduce the productivity of these formations. The critical influences of clay mineral-water interaction on the productivity of this particular type of shale plays indicates the inappropriateness of using traditional types of water-based fracturing fluids for production enhancement. Non-water-based fracturing fluids are therefore preferred, and CO 2 is preferable due to its many unique favourable characteristics, including its minor swelling effect, its ability to create long and narrow fractures at low breakdown pressures due to its ultralow viscosity, its contribution to the mitigation of the greenhouse gas effect, rapid clean-up and easy residual water removal capability. The aim of this paper is to obtain comprehensive knowledge of utilizing appropriate production enhancement techniques in clay-abundant shale formations based on a thorough literature review.

“…Large amounts of sorbed natural gas could be stored by organic materials from 20% to 80% of original-gas-in-place. Recent work demonstrates that CO2 could displace CH4 with up to a 5:1 ratio on a molecule-by-molecule basis [98] [100]. This means that by storing CO 2 in a shale gas formation, chances for gas recovery increase without significant energy penalty, and this benefit is in addition to those previously discussed regarding storage of CO2 in shales as opposed to saline aquifers.…”
