“…It has been suggested that any technology used to geologically store CO 2 underground should store it for a minimum of 1,000 years with a leakage rate of less than 0.1% per year. ,, That the leakage rate should be low is of the utmost importance, as leakage could harm the environment and even cause loss of life. , The presence of caprock is a prerequisite to considering any environment for geologic storage of CO 2 . Caprock’s sealing capacity, i.e., its ability to prevent leakage, is a critical consideration in gaining site approval and evaluating the economic feasibility of a CO 2 storage project . Likewise, issues pertaining to safety and economic feasibility are critical to gaining public acceptance …”

“…Caprock's sealing capacity, i.e., its ability to prevent leakage, is a critical consideration in gaining site approval and evaluating the economic feasibility of a CO 2 storage project. 6 Likewise, issues pertaining to safety and economic feasibility are critical to gaining public acceptance. 7 Argillaceous rocks (mudstones, clays, and shales) and evaporites (salts and anhydrite) are commonly identified caprocks for CO 2 storage.…”

CO(2) capture and geologic sequestration is one of the most promising options for reducing atmospheric emissions of CO(2). Its viability and long-term safety, which depends on the caprock's sealing capacity and integrity, is crucial for implementing CO(2) geologic storage on a commercial scale. In terms of risk, CO(2) leakage mechanisms are classified as follows: diffusive loss of dissolved gas through the caprock, leakage through the pore spaces after breakthrough pressure has been exceeded, leakage through faults or fractures, and well leakage. An overview is presented in which the problems relating to CO(2) leakage are defined, dominant factors are considered, and the main results are given for these mechanisms, with the exception of well leakage. The overview includes the properties of the CO(2)-water/brine system, and the hydromechanics, geophysics, and geochemistry of the caprock-fluid system. In regard to leakage processes, leakage through faults or fracture networks can be rapid and catastrophic, whereas diffusive loss is usually low. The review identifies major research gaps and areas in need of additional study in regard to the mechanisms for geologic carbon sequestration and the effects of complicated processes on sealing capacity of caprock under reservoir conditions.

“…The development or the adaptation of the existing methods for geological risk assessment of CO 2 storage has become a research issue only recently. The need for further development of these methods has been repeatedly indicated both in world and national literature [21][22][23]. This applies in particular to the following two aspects:…”

An Assessment of the Formations and Structures Suitable for Safe CO2 Geological Storage in the Upper Silesia Coal Basin in Poland in the Context of the Regulation Relating to the CCS

The paper presents an analysis of the possible location of geological formations suitable for CO2 storage in the Upper Silesia Coal Basin, Poland. The range of the reservoir has been determined on the basis of an analysis of basic geological parameters, which determine the selection criteria for sites suitable for CO2 storage. A dynamic modelling of the CO2 distribution in the aquifer is presented. Based on the constructed model of migration, reactivity, and geochemical transport of CO2 in geological structures, it is possible to identify potential migration routes and escape sites of CO2 on the surface. The analysis of the technical and geological possibilities of CO2 storage was carried out according to the regulations of the complex Polish geological law, specifically in terms of sequestration possibilities in geological formations.
