Based on analogy between isothermal drying of porous media and molecular diffusion in a single-block model containing a volatile liquid during lean gas injection, a detailed procedure is presented for two-dimensional quasi-static pore network modelling of diffusion. A modified invasion percolation algorithm is used to account for evaporation of liquid clusters formed during gas injection process. Diffusion in gas phase, capillaryinduced flow in liquid phase, and evaporation in gas-liquid interface were modelled to trace the movement of gas-liquid interface and desaturation profile. Using a set of throat sizes with normal distribution, 15 cases of a regular pore network model were proposed by rearranging throat positions in the model. Results of this study indicate that diffusion time, breakthrough time, vapour partial pressure gradient, liquid saturation gradient, liquid cluster frequency, gas-liquid interface frequency, and evaporation potential are strong functions of throat sorting. Correlation coefficient of throat size with position was used to capture the disorder of porous medium. It was shown that such a correlation coefficient is not capable of describing diffusion characteristics.

“…11b for comparison; the surface tension is then under-predicted by nearly 20% by the method of Fanchi. Huygens et al [59] have also applied the parachor method of Hough and Stegemeier [61] and the Lee and Chien method [62] and found average deviations between prediction and experiment of 25 and 29%, respectively. Hence, the predictions of the gradient theory are consistently more accurate than those of these methods.…”

“…The parachor method is sensitive to the accuracy of the parachor because of the fourth power relationship between the IFT and the parachor. Gasem et al (1989) compared the Weinaug-Katz (1943), Lee-Chien (1984) and Hugill-van Welsenes (1986) models. The results indicated that each of these models could represent the data with average errors of less than 10% if a scaling exponent of 3.6 was incorporated in the models and some parameters were tuned to fit experimental data.…”

A generalized corresponding-states model based on two reference fluids and a parachor correlation were developed for the prediction of interfacial tensions for non-polar and weakly polar pure fluids and mixtures. Pure methane and n-octane were chosen as reference fluids of the corresponding-states model. The two models were tested on 86 pure substances, more than 30 binary and multicomponent mixtures, 1 1 naphtha reformate cuts, 6 petroleum cuts and 2 North Sea oil mixtures. The calculated results were found to be in good agreement with experimental data.Un modele d'etats correspondants generalise s'appuyant sur deux fluides de reference et une correlation de parachor a ete mis au point pour la prediction des tensions interfaciales pour des fluides et des melanges purs non polaires et legerement polaires. Du methane et du n-octane purs ont ete choisis comme fluides de reference du modele d'etats correspondants. Les deux modeles ont ete testes sur 86 substances pures, plus de 30 melanges binaires et multicomposants, 11 coupes de reformat de naphta, 6 coupes de petrole et 2 melanges de petrole de la mer du Nord. On a trouve un bon accord entre les resultats calcules et les donnees experimentales.Keywords: corresponding-states, parachor, interfacial tension, reference fluids.he interfacial tension (IFT) is an important parameter for T modeling many secondary and tertiary recovery processes of petroleum reservoir fluids. In immiscible displacements, the efficiency of the recovery process is influenced by the IFT between the fluid phases present in the reservoir. In gas condensate systems, for instance, the low JFT is the dominant fluid property which determines relative permeabilities and residual liquid saturations. There are several methods available for predicting IFTs, e.g. the parachor method, the gradient theory and the corresponding-states theory.The standard method of IFT predictions in reservoir simulators is the parachor method proposed by Weinaug and Katz (1943) and its extensions. The parachor method is sensitive to the accuracy of the parachor because of the fourth power relationship between the IFT and the parachor. Gasem et al. (1989) compared the Weinaug-Katz (1943), Lee-Chien (1984) and Hugill-van Welsenes (1986) models. The results indicated that each of these models could represent the data with average errors of less than 10% if a scaling exponent of 3.6 was incorporated in the models and some parameters were tuned to fit experimental data. More recently, Ali (1994) reviewed the methods for estimating the parachors of petroleum fractions and pseudocomponents and compared seven existing IFT correlations. All the correlations predicted the results with deviations around 2040%.The gradient theory (GT) of interfaces has been successfully used for estimating interfacial properties of pure fluids and mixtures (Carey et al., 1978, Sahimi and Taylor, 1991, Cornelisse et al., 1993. However, since the GT is complicated and time-consuming, it is difficult to apply the GT to multicomponent mixtures and re...
