“…As described in Section , gels used for CO 2 conformance control and leakage remediation can mainly be divided into inorganic silicate gels and polymer gels. For inorganic silicate gels, some of them have experienced injectivity problems during injection into reservoir matrix rock . In addition, silicate gels are somewhat brittle gels and are not particularly strong gels compared to polymer gels when used for high-permeability reservoirs .…”

Comprehensive Review of Sealant Materials for Leakage Remediation Technology in Geological CO₂ Capture and Storage Process

Carbon capture and storage (CCS) technology has been widely investigated to decrease the greenhouse effect. Geological CO2 storage sites are targeted mainly on depleted petroleum reservoirs or deep saline aquifers. However, CO2 leakage might take place through wellbores, cap rocks, reservoir fractures, or faults during or after the process of CO2 storage leading to environmental problems. To minimize these hazards, different kinds of sealants have been developed and applied. This review aims to summarize those materials applicable to CO2 leakage remediation. On the basis of the sealing mechanisms and compositions of different sealant materials, they were divided into seven major types: Portland cement, geopolymer cement, resins, biofilms barriers, gel systems, foams, and nanoparticles. For different types of sealants, their application background, chemical and physical properties, CO2 leakage remediation mechanism, impact factors of sealing performance, advantages, and limitations were summarized. Future development directions for these sealant materials are also recommended. To solve the problem caused by the weak acid-resistant performance of Portland cement, anti-CO2 materials should be developed and added to the formulation. Environmentally friendly materials need to be designed to replace some current user-hostile compositions in the geopolymer cement. Moreover, chemicals that can control the geopolymerization process are also required because of the high curing temperature requirement for the recent geopolymer productions. The injectivity of Portland cement and resin limits its application for in-depth CO2 leakage control; however, gels with relatively low viscosity during the injection can be a good alternative, although their thermal stability and strength need to be further enhanced. Biotechnology and nanotechnology are perspectives to be applied in the CO2 leakage control process. Foams with good stability might be used for CO2 leakage remediation in the porous medium without fractures, but their life cycle should be prolonged.

“…The following two rock types were analyzed: 1. Berea sandstone (Figure 1a) from Ohio, USA, which is a quartz sandstone with a permeability of 133 ± 39.2 mDarcy [49] and a porosity of 20.0%. Permeability for the Berea sandstone was measured using our in-house multiphase core flood system by DCI test system corporation by recording ∆P values at different flow rates injection Milli Q water through the core.…”

Micro-computed tomography (micro-CT) is increasingly utilized to image the pore network and to derive petrophysical properties in combination with modelling software. The effect of micro-CT image resolution and size on the accuracy of the derived petrophysical properties is addressed in this study using a relatively homogenous sandstone and a heterogenous, highly porous bioclastic limestone. Standard laboratory procedures including NMR (nuclear magnetic resonance) analysis, micro-CT analysis at different image resolutions and sizes and pore-scale flow simulations were used to determine and compare petrophysical properties. NMR-derived pore-size distribution (PSD) was comparable to the micro-CT-derived PSD at a resolution of 7 µm for both the rock types. Porosity was higher using the water saturation method as compared to the NMR method in both rocks. The resolution did not show a significant effect on the porosity of the homogeneous sandstone, but porosity in the heterogeneous limestone varies depending on the location of the sub-sample. The transport regime in the sandstone was derived by simulations and changed with the resolution of the micro-CT image. The transport regime in the sandstone was advection-dominated at higher image resolution and diffusion-dominated when using a lower image resolution. In contrast, advection was the dominant transport regime for the limestone based on simulations using higher and lower image resolutions. Simulation-derived permeability for a 400 Voxel3 image at 7 µm resolution in the Berea sandstone matched laboratory results, although local heterogeneity within the rock plays an integral role in the permeability estimation within the sub-sampled images. The simulation-derived permeability was highly variable in the Mount Gambier limestone depending on the image size and resolution with the closest value to a laboratory result simulated with an image resolution of 2.5 µm and a size of 300 Voxel3. Overall, the study demonstrates the need to decide on micro-CT parameters depending on the type of petrophysical property of interest and the degree of heterogeneity within the rock types.

“…In addition, the foam gel system generates foam by adding a foaming agent or surfactant, and finally blocks gas channeling or leakage channels in the form of foam, which has the strength property of gel [11]. In addition to the above classification system, inorganic gel is a system with silicate as the main component, which is induced to form gel by pH change [12,13]. Based on this, the gel system is divided into four categories: polymer gel, particle gel, foam gel and inorganic gel.…”

Injection of CO2 into hydrocarbon reservoirs is an attractive method to enhance hydrocarbon recovery and CO2 storage. However, the non-homogeneity of hydrocarbon reservoirs can lead to low sweep efficiency during CO2 flooding and leakage during CO2 storage. This inhomogeneity can be caused by highly permeable matrices and microfractures, which provide channels for CO2. Gel plugging technology is an effective technique to prevent gas escape and plays an important role in CO2 flooding and storage. Polymer gel system has good injection ability and can achieve in-depth plugging.Particle gel system has high strength, acid and temperature resistance, and can realize long-term sealing. Foam gel has good injectability and cost advantages, and less damage to the formation. Inorganic gel has good injectability and strong chemical stability. This paper reviewed the research progress and existing problems of four kinds of hydrogels and looked forward to the future development of the CO2 consistency control gel systems.
