Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...
In this Special Issue, all aspects of fluid flow and heat transfer in geothermal applications, including the ground exchanger, conduction, convection porous media, are considered. The emphasis here is on mathematical computational conventional unconventional reservoirs, engineering, drilling enhanced oil recovery (hydraulic fracturing, steam-assisted gravity drainage (SAGD), CO2 injection, etc....
gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...
PURPOSE Several risk factors for development of reexpansion pulmonary edema (REPE) after drainage of pneumothoraces have been reported, but the association between the method of thoracostomy and the development of REPE is unknown. The aim of this study was to compare the frequency of REPE after treatment of spontaneous pneumothorax with trocar or hemostat assisted closed thoracostomy. MATERIA...
