... ABSTRACT As a caprock for CO 2 geological sequestration, the mechanical properties of shale may change significantly from the long-term CO 2 -fluid interaction. To study the long-term effects of supercritical CO 2 -brine interaction on the mechanical properties of shale, the marine LMX shale...

... of high flowback rate and low oil production rate. This may be attributed to strong water-rock interactions during hydraulic fracture operation. When water-sensitive minerals in rocks encounter water, clay expansion and particle migration occur, resulting in reduction of rock strength and fracture...

... of fluid driven fractures and their interaction with weak discontinuities in subsurface phenomena is of significant interest for many industrial applications, such as geothermal energy production, O&G reservoir stimulation and CO 2 storage, among several others Kneafsey et al .

... ABSTRACT Fine-grained sediments, mudrocks and shales have unique fabric and pore topology that reflect their mineral composition and formation history. Atomic-scale clay-clay electrical interactions coexist with the micron-scale mechanical interactions between silicate and carbonate grains...

... ABSTRACT The interaction between hydraulic fractures and natural fractures will directly affect the complexity of fractures, which is an important content that needs to be paid attention to in the fracturing process. To study the interaction between hydraulic fractures and natural fractures...

.... Based on a complex stress function in bipolar coordinates, the analytical solution of casing stress distribution is obtained. The prediction model of burst strength is established, in which the mechano-electrochemical (M-E) interaction is considered. Next, the accuracy of this model is validated...

... reservoirs, rock deformation, water-rock interactions and fracture propagation. Using this model, the propagation mechanism of fracture induced by water flooding was discovered and then factors controlling fracture propagation were discussed. The main conclusions are (1) the heterogeneity magnitudes of rock...

... and gas and may affect possible storage of CO 2 and H 2 . The interaction between artificially introduced fluids and shale formations, leading to softened shale, is attributed to the interlayer expansion of clays and the dissolution of cementing carbonates. This study seeks to investigate of the effects...

... compression tests. According to the results, the SCCO 2 -water-shale interaction induced the dissolution and precipitation of shale minerals during the immersion test. In addition, the average pore size of QK samples increased due to the dissolution of minerals, while the strong swelling effect and mineral...

It was cross-validated with Molina's (2019) analytical model and Morales’ (2020) mechanical testing apparatus, enabling the evaluation of hydraulic and mechanical interactions, such as pressure communication, fracture merging while propagation, and stress shadowing (Molina, 2019; Morales...

... ABSTRACT Sedimentary rocks contain abundant pre-existing discontinuities that directly impact the trajectory of the fracture propagation. In this study, the Semi-Circular Bend (SCB) test was employed to investigate the interaction of opening mode fracture with multiple pre-existing...
