The Berriasian-Valanginian Fahliyan Formation forms one of the giant reservoirs in the subsurface of the Abadan plain, onshore Iran. A detailed petrographical analysis of the available cores and thin sections revealed that the different diagenetic parameters influenced the reservoir quality of the Fahliyan Formation in this field. The Fahliyan Formation has been influenced by three diagenetic e...

The permeability and tortuosity of pore-scale two and three-dimensional random porous media were calculated using the Lattice Boltzmann method (LBM). Effects of geometrical parameters of medium on permeability and tortuosity were investigated as well. Two major models of random porous media were reconstructed by computerized tomography method: Randomly distributed rectangular obstacles in a uni...

HOUSTON–The fundamental properties of gas shales make them virtually impossible to analyze with conventional core analysis methods or petrophysical models based on log data. This includes permeabilities in the tens to hundreds of nanoDarcies, low effective porosities (typically less than 10 percent), and high kerogen and clay contents. The tightness of the rock and the abundance of clay mineral...

A numerical model is developed to study reactive transport at pore scale. It couples lattice Boltzmann and finite volume methods to compute fluid flow and reaction processes. The model is validated by comparing numerically simulated reactive flow against the published results of dynamic imaging of carbonate dissolution. The porosity profiles and permeability-porosity relationship are compared w...

In this work, geochemical modelling using PhreeqC was carried out to evaluate the effects of reactions on performance underground hydrogen storage (UHS). Equilibrium, exchange, and mineral were considered in model. Moreover, reaction kinetics effect over an extended period 30 years. The developed model first validated against experimental data adopted from published literature by comparing valu...

Pore structure, tortuosity and permeability are considered key properties of porous materials such as cement pastes to understand their long-term durability performance. Three-dimensional image analysis techniques were used in this study to quantify pore size, effective porosity, tortuosity, and permeability from the X-ray computed tomography (CT) images of deteriorated pastes that were subject...

Abstract An essential greenhouse gas effect mitigation technology is carbon capture, utilization and storage, with dioxide (CO 2 ) injection into underground geological formations as a core of sequestration. Developing robust 3D static model the formation interest for CO storage paramount to deduce its facies changes petrophysical properties. This study investigates depleted oilfield reservoir ...

Steam-water capillary pressure is of central importance in geothermal reservoir engineering, however it is still poorly known due to the difficulty making direct measurements. To this end, we have conducted experimental and theoretical studies over the past five years and have made significant progress in understanding fundamental steamwater flow. In this paper, we summarize and discuss the res...

The relations among the resistivity, elastic-wave velocity, porosity, and permeability in Fontainebleau sandstone samples from the Ile de France region, around Paris, France were experimentally revisited. These samples followed a permeability-porosity relation given by Kozeny-Carman’s equation. For the resistivity measurements, the samples were partially saturated with brine. Archie’s equation ...

Microporosity hosts a significant portion of the total hydrocarbon volume in Middle Eastern carbonate reservoirs. An improved understanding microcrystals' morphology that micropores, their impact on reservoir properties, and spatial distributions will contribute to more accurate quality prediction. This study proposes methodology utilizes machine learning approaches for microporosity characteri...
