Abstract: METHOD FOR STIMULATION OF WELLS WITH CARBON DIOXIDE OR NITROGEN BASED FLUIDS   CONTAINING HIGH PROPPANT CONCENTRATIONS                 Abstract of the Invention The present invention relates to a method of frac-turing subterranean formations and placing proppant material in the created fracture utilizing carbon dioxide or nitrogen containing fluid.  An aqueous liquid-liquid carbon dioxide emulsion fluid is prepared having an internal phase ratio in the range of from about 50 to in excess of about 96 percent and introduced into the subterranean formation to be frac-tured.  The emulsion is heated by the formation to a temper-ature above the critical temperature of carbon dioxide and the carbon dioxide is caused to be converted to a vapor whereupon the emulsion becomes a foam.  The volume of liquid carbon dioxide is adjusted as the volume of proppant material varies to at least substantially maintain a constant inter-nal phase ratio in the treatment fluid.  When nitrogen is utilized, a foam is produced on the surface by admixing gaseous nitrogen with the gelled fluid.  The formation is fractured by the treatment fluid and the proppant is placed in the created fracture.  The fluid having maintained therein substantially a constant internal phase ratio is capable of transporting greater quantities of proppant than foams having a comparable quality.

Abstract: Abstract of the Disclosure A nonhierarchical switching system employing a modified unified algorithm for developing link sizes for paths that connect switches in the system and routing sequences for the switches in the system, and further employing means for updating the routing sequences to minimize potential blocking in the network.  In one embodiment, the modified unified algorithm develops improved link size determinations by taking advantage of traffic sensitive dynamic routing on the alternate paths available in the nonhierarchical switching system for connecting any switch to any other switch in the system. Updating of the routing sequences is achieved in that embodiment by evaluating the least loaded path for each potential connection of two switches in the system and, when appropriate, by installing the least loaded path as the second choice path in the routing sequence for that potential connection.
