We have investigated experimentally the competition between viscous, capillary, and gravity forces during drainage in a two-dimensional synthetic porous medium. The displacement of a mixture of glycerol and water by air at constant withdrawal rate has been studied. The setup can be tilted to tune gravity, and pressure is recorded at the outlet of the model. Viscous forces tend to destabilize th...

water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...

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....

iran is well known for having countless historical and instrumental records of tectonic events. shahriary catchment, as a study area, is part of the zagros collision seismic province. this research aimed to introduce a new method which is useful in identifying the relative active tectonic events of an area. the research method was designed in order to calculate the relative active tectonic inde...

Soap bubbles are by essence fragile and ephemeral. Depending on their composition environment, bubble bursting can be triggered gravity-induced drainage and/or the evaporation of liquid presence nuclei. In this paper, we design made a composite film able to neutralize all these effects keep integrity for more than one year in standard atmosphere.

A 68-year-old patient with a pT3pN2 duodenal adenocarcinoma underwent pancreaticoduodenectomy. Because the jejunal loop was anastomosed with a previous gastroenterostomy, endoscopic examination of the pancreatic and biliary anastomoses was easily feasible. On the 5th postoperative day, the patient developed septic shock and multiorgan failure; bilious secretions were noted coming from the abdom...

Chest tube insertion is a common procedure usually done for the purpose of draining accumulated air or fluid in the pleural cavity. Small-bore chest tubes (≤14F) are generally recommended as the first-line therapy for spontaneous pneumothorax in non-ventilated patients and pleural effusions in general, with the possible exception of hemothoraces and malignant effusions (for which an immediate p...

Heavy oil reservoirs are often characterized by high viscosity and poor mobility, which is more complex with the presence of bottom water. The conventional vertical well development method has low recovery efficiency limited controlled reserves a single well. In addition, water cut can increase dramatically when edge-bottom breaks through. Horizontal CO2 huff-n-puff an effective alternative mod...

A technique capable of capturing the dynamics of reservoir fluids in the proximity of production wells would provide enormous benefits to the reservoir management. In fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize production. This paper validates the feasibility of a borehole radar tool as a permanent down-hole sensor for near-w...
