... of state connate water saturation gibb free energy saturation chemical potential Introduction Thermodynamic behavior of reservoir fluids in unconventional formations has attracted much attention in recent years due to the soaring importance of such resources in the global energy supply...

... within the commercial simulators, in order that one can use them to accurately simulate the development of shale gas reservoirs. In this paper, we first derived the correction formulas for the bulk porosity, free gas saturation, and connate water saturation used for correcting the disregarded volume...

... Abstract Irreducible water saturation is an important attribute to quantify reservoir petrophysical quality in terms of flow capacity. High in-situ capillary pressure causes connate water saturation in reservoir rocks to approach the irreducible stage, thereby providing a direct link between...

... of connate water on VAPEX performance using physical model experiments carried out in a visual model, with different connate water saturations. Butane was used as the solvent and fine Ottawa sand was used for packing the model to obtain permeability and capillary pressure values comparable to the field...

... Texas Basin. Similar to other BCGSs, the Bossier sands are sometimes characterized by an abnormally high capillary pressure profile associated with an ultra-low connate water saturation distribution. We use a vapor desorption technique to measure capillary pressures as high as 10,000 psi...

... ABSTRACT Predictions of oil recovery by immiscible gas injection require accurate laboratory determination of gas-oil capillary pressures. Two series of drainage capillary pressure measurements were performed on sandstone core samples with and without connate water saturation. Binary mixtures...
