Pore pressure and gas saturation distribution in sedimentary basins are difficult to predict quantify because these two factors produce the same impact on reducing P-wave velocity (Vp). To tackle this issue, modified Eaton's equation for Vp S-wave (Vs) ratio derived from automatic analysis a pre-stack inversion was applied estimate pore distribution, Rock Physics Templates (RPTs) performed hydr...

Abstract Micromodel can provide valuable information to improve understanding of pore-scale transport phenomenon and also be utilized simulate the process at pore scale. This research aims propose settlement option for quantification suspended solids in micromodel. The micromodel is used mimic formation damage which occurs reservoir that could simultaneously affect enhanced oil recovery. done b...

constant rate of strain (crs) consolidation is a rapid test method used for determination of compressibility of clayey soils. in a crs test, the appropriate strain rate is selected based on pore water pressure ratio, i.e. the ratio of pore pressure to total stress. in the present study, to investigate the effect of strain rate on variation of relative pore water pressure, four different clay sa...

Fast synchrotron-basedX-raymicrotomographywas used to image the injection of super-critical CO2 under subsurface conditions into a brine-saturated carbonate sample at the pore-scale with a voxel size of 3.64μm and a temporal resolution of 45s. Capillary pressure wasmeasured from the images by finding the curvature of terminal menisci of both connected and disconnected CO2 clusters. We provide a...

Cellular conditions experienced during energy-limited states--elevated calcium, shifts in cellular adenylate status, compromised mitochondrial membrane potential--are precisely those that trigger, at least in mammals, the mitochondrion to initiate opening of the permeability transition pore, to assemble additional protein release channels, and to release pro-apoptotic factors. These pro-apototi...

Frozen seawater is a composite material with a sponge-like structure. The framework of the structure is composed of pure ice, and within the pores exists a concentrated seawater brine. When the temperature is reduced, the volume of this residual brine decreases, while its salinity increases. As a result of the paired changes to temperature and salinity, the brine eventually becomes supersaturat...

Article history: Received 10 December 2015 Received in revised form 27 February 2016 Accepted 29 February 2016 Available online 2 March 2016 We investigate the impact of initial pore structure and velocity field heterogeneity on the dynamics of fluid/solid reaction at high Péclet numbers (fast flow) and low Damköhler number (relatively slow reaction rates).

This study explored the bacterial diversity of brines used for cheesemaking in Italy, as well as their physicochemical characteristics. In this context, 19 brines used to salt soft, semi-hard, and hard Italian cheeses were collected in 14 commercial cheese plants and analyzed using a culture-independent amplicon sequencing approach in order to describe their bacterial microbiota. Large NaCl con...

[1] While geological carbon dioxide (CO2) storage could contribute to reducing global emissions, it must be designed such that the CO2 cannot escape from the porous rock into which it is injected. An important mechanism to immobilize the CO2, preventing escape, is capillary trapping, where CO2 is stranded as disconnected pore-scale droplets (ganglia) in the rock, surrounded by water. We used X-...
