Salt Precipitation‐Driven Rock Failure Mode Transition During Geological CO2 Sequestration
Abstract Salt precipitation has emerged as a critical factor affecting injectivity, reservoir stability, and the potential to trigger near‐wellbore microseismic activity during geological CO2 sequestration. While previous studies have primarily focused on the brine acidification induced by CO2 injection, triggering geochemical reactions in carbonate ...

Resistivity Change Mechanism in the Carbon Dioxide Sequestration Process
This study explores the variation law, influencing factors, and mechanisms of resistivity in the interaction between CO₂ and saltwater. This study used a hollow PEEK conductor to simulate core pores. With excellent thermal stability, mechanical strength, and electrical insulation, its homogeneous, nonporous nature eliminates interference from rock ...

Facies and Depositional Environment Analysis of Alternate Channel Bodies in the Flank of a Sag Structure [PDF]
The down-dip (40o) portion turbidite Cenozoic deposits of the western sag structure in the Bohai bay been characterized for stratigraphy. Laterally tracking continuity in temporal data becomes challenging with increase in offset. In achieving this and

Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

The Influence of Microporous Cements on the Pore Network Geometry of Natural Sedimentary Rocks
We investigate the pore network geometry and permeability of six natural sandstones and carbonate rocks. Using 3D microtomographic images, we segment each rock sample into three phases: Solid matrix of grains, macropores containing void spaces, and a ...

Pore‐Scale Transition Behavior of Digital Carbonate Rock Dissolution During CO2 Geo‐Sequestration
Abstract Carbon dioxide‐rich brine formation during geological carbon sequestration induces calcite dissolution, governed by the physicochemical coupling of fluid flow, reactive transport, and pore structure evolution. Unveiling the mechanisms that control this dissolution, particularly under varying flow and structural conditions, is essential for ...

Permeability and Induced Polarization of Mudstones
Electrical measurements can be used to estimate hydraulic properties such as permeability (k) in sedimentary rocks. Previous work has focused on sandstones, siltstones, and carbonates, while investigations on mudstones have rarely been reported.

The brittleness index in hydraulic fracturing [PDF]
We present a new definition of a brittleness index which is used as a criterion for candidate selection of rock intervals for hydraulic fracturing. The new index is a combination of material strength parameters and insitu stresses. It was derived from an
