A geological model was built for the Sadi reservoir, located at Halfaya oil field. It is regarded as one of most significant oilfields in Iraq. The study includes several steps, essential which importing well logs from six wells to Interactive Petrophysics software conducting interpretation and analysis calculate petrophysical properties such permeability, porosity, shale volume, water saturati...

We present a reservoir simulation scheme that gives accurate resolution of both large-scale and fine-scale flow patterns. The method uses a mixed multiscale finite-element method (MMsFEM) to solve the pressure equation on a coarse grid and a streamline-based technique to solve the fluid transport on a fine-scale subgrid. Through this combination, we aim towards a numerical scheme that facilitat...

The estimation of the formation permeability is considered a vital process in assessing reservoir deliverability. prediction such rock property with use minimum number inputs mandatory. In general, porosity and are independent petrophysical properties. Despite these observations, theoretical relationships have been proposed, as that by Kozeny–Carmen theory. This theory, however, treats highly c...

Abstract To develop efficient and cost-effective desalination technologies is crucial for addressing the globally increasing needs drinking water. One such technology that growing capacitive deionization (CDI), wherein ions are electrically removed from water passing through or between two porous conducting electrodes. As CDI field grows, design principles scaling small cells to larger units mo...

Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...

Tris+/Na+ permeability ratios were measured from shifts in the biionic reversal potentials of the macroscopic ACh-induced currents for 3 wild-type (WT), 1 hybrid, 2 subunit-deficient, and 25 mutant nicotinic receptors expressed in Xenopus oocytes. At two positions near the putative intracellular end of M2, 2' (alpha Thr244, beta Gly255, gamma Thr253, delta Ser258) and -1', point mutations reduc...
