Preliminary human studies suggest the presence of an upper esophageal sphincter (UES) contractile reflex triggered by pharyngeal water stimulation. The purposes of this study were to further characterize this reflex and determine the threshold volume for its activation. We studied 10 healthy young volunteers by manometric technique before and after topical pharyngeal anesthesia. UES pressure re...
Low-permeability near-critical volatile reservoirs are characterized by light oil, complex fluid phase, and strong reservoir inhomogeneity, etc. Purely injecting CO2 will create a series of problems, such as serious gas channeling, low sweep efficiency, oil recovery. Therefore, in this paper, through combination experiments simulations the process studying problem from simple to complex, we car...
A theoretical model for carbon dioxide (CO2) migration in tilted aquifers with groundwater flow is presented to evaluate the injection of CO2 into a geological formation. Capillary force in the flow of two immiscible fluids in a porous medium creates a saturation transition zone, where the saturation changes gradually. A vertical equilibrium assumption is employed to solve for the capillary pre...
