Complexities in pore scale structure, rock-fluid and fluid-fluid interactions have a profound effect on the estimation of reserves, reservoir recovery and productivity in reservoir core material. These complexities determine the pore scale distribution of fluids within the pore space, which, in turn, determine the petrophysical response of the rock. A very important example is the estimation of...

We consider a heat conducting compressible viscous fluid at rest in a rigid container and show that the thermal and the kinetic energy of arbitrary disturbances of the rest state eventually decays. REsuME. On considere un fluide compressible, visqueux et conducteur de la chaleur au repos dans un reservoir rigide. On montre que l'energie thermique et cinetique de perturbations arbitraires est am...

Abstract Predicting formation damage in cased-hole and open-hole completion wells is of high importance. This especially relevant when the caused by reservoir drill-in fluids hence being well-bore induced. Cake filter removal has proven to be a good approach estimate induced evaluate fluids’ performance. We present an experimental methodology cake removal, which could achieved during well's ini...

Molecular diffusion determines the time to reach local equilibrium in a reservoir. It can be main production mechanism scenarios such as from fractured reservoirs or tight formation. However, there is lack of high-pressure coefficients for reservoir fluids and its related systems. Many correlations exist, but no consensus on their accuracy these We provide systematic review available data syste...

The performance of petroleum recovery methods is dependent on the characteristics of the reservoir rock, oil quality, and formation water. One fundamental feature for considering petroleum recovery methods is the wettability of the rock reservoir. Also, this feature impacts the displacement of fluids in the rock reservior. In the case of the limestone, which normally features oil wettability, e...

background and objectives: pneumocystis jiroveci is an important causative agent of pneumocystis pneumonia. during childhood, exposure to pneumocystis occurs and antibody was built in early childhood. the aim of this study was to describe the molecular epidemiology of p. jiroveci in children without any respiratory syndrome and survey the distribution of different mitochondrial large subunit, r...

The simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. Relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. Nowadays X-ray scanners are one of the most...

Reservoir characterization and asset management require comprehensive information about formation fluids. In fact, it is not possible to find accurate solutions to many petroleum engineering problems without having accurate pressure-volume-temperature (PVT) data. Traditionally, fluid information has been obtained by capturing samples and then by measuring the PVT properties in a laboratory. In ...

Chemical-flooding schemes for recovering residual oil have been in general less than satisfactory due to loss of chemicals by adsorption on reservoir rocks, precipitation, and resultant changes in rock wettability. Adsorption and wettability changes are determined mainly by the chemical structure and mix of the surfactants, surface properties of the rock, composition of the oil and reservoir fl...

The Olfus-Bakki geothermal area (OBGA) in SW Iceland is located in the S and SE margins of the high-enthalpy systems of Hveragerdi and Hengill, respectively. This geothermal area contains a productive region, denominated the Bakki field, which produces fluid at temperatures in the range of 100-130 °C. Since 1979, the geothermal resource has supplied thermal energy to the town of Thorlakshofn, m...
