... is the absolute permeability of the medium, and φ is the porosity. Khairy (2001) developed a new technique to estimate average capillary pressure curve for a reservoir ( Eq. 9 ). A total of 58 core samples from the Western Desert in Egypt were used to develop the correlations. This technique needs one...

... of oil-based filter cake. Berea sandstone cores with an average porosity of 18 vol% and an average permeability of 50 md were used. CT scan, XRD, SEM, and chemical analysis were used to examine the reaction characteristics of different concentrations of acid with ilmenite oil-based filter cake. Coreflood...

The applications of nanoparticles to enhance the oil recovery can be summarized in three approaches; Nanocatalysts, Nanoemulsions, and Nanofluids. In this paper, the different possible displacement mechanisms of the nanofluids...

The resulted maps were utilized for facies model creation and consequently dominated the petrophysical properties distribution: porosity, permeability, and initial water saturation...

... Abstract Multisource and multiscale modelling of formation permeability is a crucial step in overall reservoir characterization. Thus it is important to find out an efficient algorithm to accurately model permeability given well logs data. In this paper, an integrated procedure was adopted...

.... Detailed sedimentological and petrophysical study of more than 40 meters of core, consisting in core logging, microfacies analysis, SEM analysis and routine core analysis (He-porosity, horizontal air-permeability and grain density) were undertaken to determine the different facies types and their relative...

... Abstract Tight gas reservoir development has long been affected by 1) complex flow profiles and 2) the impact of very low permeability on reservoir productivity. Where well tests (WT) buildup is very short, interpretation becomes difficult and results often are ambiguous. Most WT of tight, dry...
