Complex pore structures with multiple inclusions challenge the predictive accuracy of rock physics models. This study introduces a novel method for estimating single equivalent aspect ratio that optimizes model predictions by minimizing discrepancies experimental measurements in porous rocks variable ratios and proportions. The proposed methodology uses digital numerical simulations validation. A comparative analysis is conducted between derived from optimized models, simulations,...

Abstract This work provides new insights into the dynamics of silica nanoparticle-based removal organic fluids (here oil) from naturally occurring porous media. We have used 4D (time-resolved 3D) imaging at pore-scale using X-ray computed micro-tomography (μCT) technique. The captured 3D tomographic time-series data reveal immiscible oil displacement a carbonate rock upon injection nanoparticle (NP) suspensions (0.06 and 0.12 wt% SiO 2 in deionised water). Our analysis shows significant...
Abstract This study reveals the pore-scale details of oil mobilisation and recovery from a carbonate rock upon injection aqueous nanoparticle (NP) suspensions. X-ray computed micro-tomography (μCT), which is non-destructive imaging technique, was used to acquire dataset includes: (i) 3D images sample collected at end fluid steps, (ii) 2D radiogram series during injections. The latter allows monitoring flow dynamics time resolutions down few seconds using laboratory-based μCT scanner. By...
Studies of pore systems in volcanic rocks are increasing importance due to these rocks' potential as reservoirs for hydrocarbons. For this paper, samples basaltic pahoehoe, rubbly pahoehoe and acidic lava from the Lower Cretaceous Serra Geral Group (Paraná Basin, southern Brazil) were analysed order quantify characterize constituent systems. The volcanics erupted part Paraná‐Etendeka Igneous Province Early (Valanginian – Hauterivian). Analyses included experimental measurements by...
Abstract Pore-network modelling, or digital petrophysics, is an emerging technology which allows computing physically consistent two- and three-phase flow functions such as relative permeability capillary pressure curves at arbitrary wettability. Considering the difficulty in measuring these reliably laboratory, pore-network modelling increasingly used to guide complement costly time-consuming SCAL programmes. Although now well-established for clastic reservoirs, applying it carbonate rocks...
In order to support bone tissue regeneration, porous biomaterial implants (scaffolds) must offer chemical and mechanical properties, besides favorable fluid transport. Titanium provide these requirements, depending on their microstructural parameters, the osteointegration process can be stimulated. The pore structure of scaffolds plays an essential role in this process, guiding transport for neo-bone regeneration. objective work was analyze geometric morphologic parameters microstructure...

The interconnectivity of the porous space is an important characteristic in study media and their transport properties. Hence we propose a way to quantify it relate with intrinsic permeability rocks. We measure connectivity based on geometric topological information pore-throat network, which are models built from microtomographic images, obtain analytical method compute that property. expanded handle rocks present higher degree heterogenity space, characterization requires images different...
The performance of biomaterial scaffolds for bone tissue engineering, such as porous titanium implants, is strongly dependent on their structural features; consequently, a reliable characterization essential. Research media has often adopted image analysis technique. Some conventional acquisition techniques, optical and scanning electron microscopy, provide two-dimensional (2D) images the structure, which can be limited, mainly, to characterize parameters associated with connectivity pore...
Herein, the effect of addition Ni‐coated carbon nanotubes (CNTs) on microstructure, mechanical properties, and morphology zirconia porous cellular structures is studied, aiming to increase their strength. Highly monolithic (ZrO 2 ) reinforced with Ni‐doped CNTs + CNT/Ni) are fabricated through replica method. Scanning electron microscopy micro‐computed tomography (microCT) analyses show that ZrO2 CNT/Ni specimens present lower overall porosity (88.0%) than ZrO (93.8%), indicating improved...

Petroleum reserves available worldwide are geologically based mainly on sedimentary and carbonate rocks, the reservoir performance depends intrinsic properties of each rock their response to changes in wettability. Recently, change wettability with low-salinity brine has been used improve oil recovery, which is an environmentally friendly low investment, but there no unanimity about mechanisms recovery process. Therefore, aim this study investigate process involved associated interactions...
The characterization of ceramic foams via X-ray microtomography imaging method is often restricted to a general overview samples, either perform qualitative or quantitative analyses. To assess the foam with focus on some specific components its structure, such as hollow struts' cavities and open cells, generalized characterizations must be overcome. This work presents image analysis methodologies, based open-source software, tools, plugins, achieve aforementioned characterizations. SiC ZrO2...
