“…The example in Fig. 4 is based on models of electrical conductivity from survey-design studies associated with a future fluid-injection pilot study in a coastal area near Panama City (Florida) (Jiao et al 2017). With the overarching goal of testing subsurface pressure management methods for industrialscale carbon capture and sequestration (Birkholzer et al 2012), crosswell and surface-to-borehole EM surveys accompanying a planned injection schedule are considered in order to aid the spatiotemporal plume mapping.…”

Summary Algorithmic and computational advances have made it possible that geophysical survey and earth model design can be aided by many systematic trial inverse-modeling runs with synthetic data. Such may for example come up in machine-learning approaches. Automated image appraisal pertaining to such applications will involve common statistical tests for goodness of data fit as a primary evaluation method. However, solution non-uniqueness may render multiple images equivalent in terms of their data fit, requiring secondary categorizers. A logical choice for classifying synthetic-imaging results quantifies the goodness of model fit where a known reference model replaces the observational input. The task of model inter-comparison in terms of measuring the resemblance to the reference model poses challenges to common distance-based metrics like root mean square error and mean absolute error. First, distance-based metrics can introduce spurious contributions when smooth models with fuzzy target contours are to be compared against a sharp reference. Second, large differences due to parameter-estimation overshoots can dominate distance metrics. The remedy proposed here is referred to as semblance and is based on the idea of logistic functions, where a binary dependent variable adds non-zero or zero accumulation terms for the, respectively, passing or failing of preset target thresholds. This classifying approach is amenable to an objective where model feature recognition is primary. Numerical comparisons to distance-based metrics provide evidence for the advantages of the semblance in view of this objective. Geophysical imaging in conjunction with machine-learning is seen as a benefitting upcoming application area.

“…In a complete carbon capture and storage process, CO 2 sequestration is the last and most critical step of the process, being mainly achieved through geological and oceanic sequestration as well as mineral carbonization [14][15][16]. CO 2 geological storage primarily includes CO 2 geological storage in deep saline aquifers (DSAs), depleted oil and gas reservoirs, unmineable coal seams, gas hydrate storage, and enhanced geothermal systems (Figure 1) [12,15,[17][18][19]. Among achieved through geological and oceanic sequestration as well as mineral carbonization [14][15][16].…”

Carbon geological storage (CGS) is an important global practice implemented to mitigate the effects of CO2 emissions on temperature, climate, sea level, and biodiversity. The monitoring of CGS leakage and the impact of storage on hydrogeological properties is important for management and long-term planning. In this study, we show the value of passive monitoring methods based on measuring and modeling water-level responses to tides. We review how monitoring can be used to identify time-varying horizontal and vertical permeabilities as well as independently detect time-varying fracture distribution in aquifer–caprock systems. Methods based on water-level responses to Earth tides are minimally invasive, convenient, economic (since they use existing groundwater wells), and time-continuous. We show how measurements can be used to detect aquifer leakage (caprock confinement) and the distribution of surrounding faults and fractures, which are the two most important unsolved quantities in assessing geological CO2 storage strategies.

“…CO 2 sequestration is the final step in the entire CCS process, which is mainly accomplished by geological and ocean storage, as well as mineral carbonation [5][6][7]. Among them, geological storage, such as deep saline aquifers (DSAs), depleted oil and gas reservoirs, unmineable coal seams, gas hydrate storage, and enhanced geothermal systems, is considered to be the most viable solution for reducing CO 2 emissions [3,6,[8][9][10]. Deep saline aquifers (DSAs) are widely distributed, have good sealing capabilities, and provide the most promising and feasible geological reservoir for carbon dioxide storage due to their vast storage capacity [11,12].…”

In CO2 geological storage, multiphase flow plays a vital role in the movement and distribution of CO2. However, due to the limitations of fluid buoyancy and capillary forces, CO2 encounters challenges in penetrating the caprock, and the potential for leakage remains a concern due to variations in injection conditions. The migration and distribution of CO2 in the process of CO2 geological storage in saline formations are determined by relative permeability and capillary pressure, which are key factors. Consequently, this study focuses on two essential models: relative permeability and capillary pressure models. A two-dimensional isothermal reservoir–caprock model was constructed, utilizing data from the Shenhua CCS demonstration project. The analysis indicates that the core parameters in the model are residual gas saturation and residual water saturation. Specifically, residual gas saturation governs the diffusion distance of CO2 within the reservoir–caprock system, while its combined effect with residual water saturation affects the permeation rate of CO2. Through the application of the Analytic Hierarchy Process (AHP) to analyze the impact of different models on caprock integrity, it was determined that when selecting caprock models and optimizing parameters, precedence should be given to models with lower residual saturation and caprocks that offer sufficient capillary pressure for optimal sealing effects. These research findings can serve as references for practical CO2 storage projects, providing guidance on activities such as adjusting water injection strategies and controlling gas injection pressures to optimize geological storage efficiency.
