... the tight rock. Pressure decay data for shale samples from the Eagle Ford, Utica and Bakken formations, each of varying particle diameter was obtained experimentally from batch tests and the total pressure drop was used to measure oil saturations and a pseudo capillary pressure curve was derived from...

...) extrapolation of FIB-SEM or MAPs SEM measured distribution to all SIG pores, 2) Nuclear Magnetic Resonance (NMR) estimates of pore sizes, 3) MICP estimates based on the capillary pressure curve pore throat size -volume occupied distribution, and 4) low pressure gas adsorption analyzed by B.E.T. methods. Each...

... principle models, which is particularly valuable when data are limited. We use the Young-Laplace equation to generate capillary pressure curves for two cases: where both phases are depleted from a collection of pores, so that overall composition remains constant, and where only the gas phase...

... due to the low-permeability and high capillary pressure in tight rock. This study aims at providing important theory basis for researching on the development of tight oil and gas reservoir. In this work, relative permeability curves in tight core were derived from capillary pressure curves using...
