Fracture sealing and its impact on the percolation of subsurface fracture networks
, 2022 Current uderstanding of the impact of fracture sealing on macro-scale fluid flow is insufficient. Here, we generate well-connected orthogonal fracture networks in two- and three-dimensions using a discrete fracture network method. The fracture sealing is

A multiphysical‐geochemical coupling model for caprock sealing efficiency in CO2 geosequestration
Deep Underground Science and Engineering, 2023 Precipitation or dissolution due to geochemical reactions has been observed in the caprocks for CO2 geosequestration. Geochemical reactions modify the caprock sealing efficiency with self‐limiting or self‐enhancement.

Updated Criterion to Select Particle Size Distribution of Lost Circulation Materials for an Effective Fracture Sealing [PDF]
, 2017 This paper presents a new criterion to select particle size distribution (PSD) for an effective fracture sealing. The method was developed based on a comprehensive laboratory investigation that was conducted to determine the relationship between ...

Fracture sealing in limestones, a microstructural and mineralogical study [PDF]
, 2006 Fractures significantly enhance the flow rate in rocks, if fracture density is high (Taylor 1999, Cox et al. 2001). This leads to rapid flux along a hydraulic gradient from high to low pressure reservoirs, and is represented in rocks as veins.

Observation of fracture sealing in high-strength and ultra-low-permeability concrete by micro-focus X-ray CT and SEM/EDX [PDF]
, 2014 Fracture sealing by precipitation is known to occur in high-strength and ultra-low-permeability concrete (HSULPC) immersed in water. Because a high ability to retard radionuclide migration is required for HSULPC, understanding both the sealing process ...

Energies, 2023 Under the conditions of many faults, sandbodies, and hydrocarbon sources on the slopes of faulted basins where structural traps are scarce, only a few sandbodies are capable of forming hydrocarbon pools, while most sandbodies act as aquifers.

Microbially induced calcite precipitation for sealing anhydrite fractures with gouges [PDF]
, 2022 Caprock formation forms a natural barrier for geological storage of CO2, nuclear wastes, and hydrocarbon resources. Fault and natural/artificial fractures that crosscut the storage systems represent potential leakage pathways.

Does immediate dentine sealing improve bonding effectiveness of glass ceramic restorations compared to delayed dentine sealing? [PDF]
, 2022 A systematic review of the literature was conducted to determine whether immediatedentine sealing (IDS) or delayed dentine sealing (DDS) would lead to a more effectivebond between dentine and indirect glass ceramic restorations.
