“…Within the classification of steady-state methods, four subgroups were identified in Christiansen and Howarth (1995): the multiple-core methods (also called the Perm State method), the high-rate methods, the stationary-liquid methods, and the uniform capillary pressure methods (also called the Hassler method). Christiansen and Howarth note (1995) that of the four methods the high-rate method is used most often.…”

“…Further discussion of steady-state experimental procedures and data reduction methods is found in Christiansen and Howarth (1995). Because of the simplicity of the data reduction process for steady-state experiments, the remainder of this report will describe the more complex process, data reduction methods for unsteady-state experiments.…”

“…As described in Christiansen and Howarth (1995), the gas is typically introduced to the upstream face of the rock sample from a pressure regulator, and it is withdrawn at the downstream face through a back-pressure regulator. Using iterative, trial-and-error techniques, the injection rate is maintained sufficiently high to minimize the impact of capillary end-effects on flow behavior.…”

“…In the literature of the past 10 years, increasing use of centrifuge methods for measuring relative permeability relationships was observed by Christiansen and Howarth (1995). Centrifuge methods can provide results quickly, and the centrifuge displacement is a gravity-stable displacement, free from effects of viscous fingering, In unsteady-state high-rate or low-rate methods, viscous fingering may occur.…”

“…History matching is a trial-and-error procedure that requires considerable engineering judgment and experience (Coats, 1987). A thorough literature review of the use of history matching to estimate relative permeability was not included in Christiansen and Howarth (1995); therefore it is included in this report for completeness. …”

This paper presents a novel integrated approach for numerical simulation of foam coreflood experiments in the absence and presence of oil. The experiments consisted of the coinjection of gas and Alpha-Olefin Sulfonate (AOS) surfactant solution into Bentheimer sandstone samples initially saturated with the surfactant solution [see (Simjoo & Zitha, 2013)]. The foam model implemented is based on a local equilibrium and describes dependency of foam mobility reduction factor using several independent functions, such as liquid saturation, foam velocity, oil saturation and capillary number.First, a series of numerical simulation was conducted to investigate the effect of surfactant concentration on pressure drop across the core for the foam flooding in the absence of oil. To this end, the dry-out and gas velocity functions in the foam model were determined from the experimental data obtained at low and high-quality regimes of foam flow at a constant injection velocity. Next, pressure drop profiles of foam flooding at two different surfactant concentrations were modelled to determine the parameters of the surfactant-dependent function in the foam model. The simulation results fit the experimental data of pressure drops very well. Then, the numerical simulations investigated the oil displacement, by foam where the main goal was to determine the foam model parameters dedicated to the oil saturationdependent function. The pressure drop across the core, oil-cut, and oil recovery factor were 2 modelled, and an excellent match was obtained between the pressure profile and the oil recovery obtained numerically compared with those obtained from the corresponding coreflood experiments.

Gas permeability of moulds and cores is an important factor to consider in the casting process. In foundries, gas permeability is measured by using instruments which give dimensionless numbers. This approach enables the comparison of values between samples and is often not quantified in units. In this study, a custom-made measurement system is introduced that applies Darcy's law, where pressure gradients for different flow rates are studied. The Darcian permeability in standard cylindrical samples was determined using a method that is familiar with those in earth sciences. Two types, steady-state and unsteady-state approaches were used for the calculations, and the difference in permeability values generated by these two methods is discussed. The results of a silica sand sample with furan resin and a 3D-printed sample that consists of artificial granulous material with phenolic resin were compared.
