During drainage, as a voxel of porous material is being actively invaded prior to percolation, the invading nonwetting fluid cannot be transmitted neighboring downstream until critical saturation (Snc) reached. This occurs when forms percolating path across voxel. We present novel laboratory observations gravitationally stable, air/water drainage in thin bead packs, with 2D fields monitored at ...
OBJECTIVE To determine the incidence of residual pneumothorax after video-assisted thoracic sympathectomy, with and without postoperative pleural drainage, and to evaluate the possible influence of this type of pneumothorax on postoperative pain within the first 28 postoperative days. METHODS All patients presenting symptoms consistent with primary palmoplantar hyperhidrosis and treated at th...
The Tokyo Guidelines of 2007 (TG07) described the techniques and recommendations of biliary decompression in patients with acute cholangitis. TG07 recommended that endoscopic transpapillary biliary drainage should be selected as a first-choice therapy for acute cholangitis because it is associated with a low mortality rate and shorter duration of hospitalization. However, TG07 did not include t...
Single catheter gravity drainage of the right atrium or right ventricle during total cardiac bypass.
The currently employed cannulations preparatory to establishing cardiac bypass with the aid of a pump-oxygenator, include isolation of the superior and inferior vena cavae over tapes and the insertion of catheters into each of these vessels. t At the onset of bypass the caval tapes are tightened around the indwelling catheters and venous drainage is effected by suction applied to the venous lin...
Fractured carbonate reservoirs account for 25% of world’s total oil resources and for 90% of Iranian oil reserves. Since calcite and dolomite minerals are oil wet, gas oil gravity drainage (GOGD) is known as the most influencing production mechanism. The most important issue within gas injection into fractured media is the channeling problem which makes the efficiency of gas injection process e...
Naturally fractured carbonate reservoirs (NFCRs) comprise the majority of the oil and gas reservoirs around the Persian Gulf. Many of these reservoirs have a long history of exploitation, but vast amounts of oil remain in place. A major redevelopment process for light oil based NFRs will likely be the use of horizontal wells combined with gravity drainage at constant pressure based on voidage...
