Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...

Relative permeability is affected by several flow parameters, mainly the operating temperature and fluid viscosity. Fluid viscosities change with temperature, which correspondingly affects relative permeability. Temperature believed to have a considerable effect on oil–water permeability, thus vital input parameter in petroleum reservoir production modelling. The actual of oil-water curves has ...

The thin water film stabilized by disjoining pressure is non-negligible in tight formations which results significant difference multiphase flow behavior compared with that conventional formations. In this work, a pore network model proposed to simulate two phase highlight the contribution of on flow. newly developed includes influence fluid configuration, capillary entry pressure, conductance ...

We describe the early stages of a poreto coreto reservoir-scale investigation of wettability variation and its impact on flow during oil recovery. We use a threedimensional pore-scale network representation of a Berea sandstone to predict relative permeability and capillary pressure hysteresis. We successfully match experimental data for the water-wet case, and then focus upon the effect of var...

The relative permeability of coal to gas and water exerts a profound influence on fluid transport in seams both primary enhanced coalbed methane (ECBM) recovery processes where multiphase flow occurs. Unsteady-state core-flooding tests interpreted by the Johnson–Bossler–Naumann (JBN) method are commonly used obtain coal. However, JBN fails capture multiple gas–water–coal interaction mechanisms,...
