Many world class large carbonate reservoirs leave behind at least half of the initial oil in place. Typically water injection is used to improve oil recovery while gas injection is used to maintain pressure or to promote oil gravity drainage. Immiscible gas injection, including injection of CO2, has been considered but not implemented on a large scale for economic reasons. Furthermore, interest...

It has been suggested that positive expiratory pressure may assist the clearance of bronchial secretions in the treatment of cystic fibrosis. It has been compared with currently used postural drainage techniques. Three treatment regimens were compared in 18 patients with cystic fibrosis. Treatment A consisted of breathing exercises emphasising inspiration, interspersed with the forced expiratio...

Processing, stability and sensorial perception of food foams are tightly related to their microstructure flow behavior. Characterization corresponding physical parameters is central for product development quality control. An experimental setup enabling in-situ characterization yield stress, gas volume fraction bubble size distribution at different heights within a foam column created in commer...

We study drainage in a horizontally oriented rough fracture joint filled with glass beads. The shape and structure of the drained areas is the result of competition between two effects: (1) variations in the capillary thresholds necessary to be overcome in order to drain the pores and (2) the height variations due to the roughness of the fracture joint. These height variations have long range c...

Dam is set in large hydropower station. Cushion pool built behind the dam for flood discharge and energy dissipation of reservoir. Operation some time, dewatering structure safety which study, then cushion filled. Temporary dewater filled system used by previous engineer, but arranged controlled hard. Based on need filling, an example Baihetan station, necessity feasibility are study. Then a pe...
