The influence of micro-porosity on drainage relative permeability using digital core analysis
… the effect of micro-porosity on the effective permeability of the wetting phase is more evident at lower saturations, the error associated with its exclusion is still significant at high wetting phase saturations. The results also prove that the proposed upscaling approach is superior compared …

An experimental investigation of some capillary pressure-relative permeability correlations for sandstone reservoir rocks.
The water-oil relative permeability of the reservoir rock is one of the essential properties in petroleum engineering studies, and the use of this data is critical in the evaluation and management of oil fields, particularly in water flooding predictions and oil recovery calculations. The …

A development of regression models for predicting two-phase relative permeability in consolidated rock
… equations for the water-oil imbibition relative permeability and gas-oil drainage relative permeability from experimental data.</p> <p> Laboratory relative permeability data along with the corresponding rock and fluid properties were collected, and stepwise linear regression analysis was …

Relative Permeability Experiments of Carbon Dioxide Displacing Brine and Their Implications for Carbon Sequestration
… set of experiments was designed to measure CO 2 relative permeability for CO 2 displacing brine at residual brine saturation. Endpoint drainage CO 2 relative permeability was found to be tightly clustered around 0.35-0.4. These values indicate that CO 2 is not strongly nonwetting, and are …

On relative permeability : a new approach to two-phase fluid flow in porous media
… two-phase flow through the standard approach of relative permeability, in which permeability, rather than being a unique property of the porous medium, becomes a joint property of the porous medium and each fluid phase. The goal of this study is to find a proper, alternate approach to relative …

Prediction of Capillary Pressure and Relative Permeability Curves using Conventional Pore-scale Displacements and Artificial Neural Networks
… and two-phase capillary pressure and relative permeability curves. These parameters are then used as input to train an ANN. ANN theories and related applications have been significantly promoted due to the fast increasing performance of computer hardware and inheratively complicated …

Numerical and experimental study of the impact of temperature on relative permeability in an oil and water system.
Relative permeability is affected by several flow parameters, predominantly operating temperature and fluid viscosity. Fluid viscosity changes with temperature, which correspondingly affects the relative permeability. Temperature is believed to have a considerable effect on oil–water relative …

Effect of temperature on oil/water relative permeabilities in microfluidic micromodel, The
… the effect of temperature on oil/water relative permeability. Many contradictions and disagreements have been observed in these studies. Some studies have shown the effect of temperature, others have disagreed with that by attributing changes to other experimental errors, such as viscous …

Experimental and Simulation Study of Relative Permeabilities in Heavy Oil/Water/Gas Systems
… study was conducted to investigate the relative permeability behaviour of a typical Canadian bitumen, water and gas. Series of isothermal core flood experiments were conducted on an unconsolidated core composed of cleaned Athabasca sand matrix and relative permeabilities of the involved …

A Study of Transport of Micellar Fluids in Porous Media
Two- and three-phase relative permeabilities have been measured for a low interfacial tension brineoil- surfactant-alcohol mixture in a Berea sandstone core. The measurements were done at steady-state with a constant nominal capillary number of 10^-2. Residual phase saturation (capillary …

Natural state modelling of a vapor dominated system : case study Darajat, Indonesia
… This study also investigates the sensitivity to relative permeability functions for production modelling. However, these cannot be calibrated due to this study being only natural state modelling. The expanded stratigraphy and resistivity models enhance comprehension in lateral distribution of …
