IPC: E21B43/24
Filed: 1995-11-14
Granted: 2005-12-20
Abstract: Heavy oil may exist as unconsolidated deposits in thin zones, sometimes underlain by bottom water, which deposits flow under solution-gas drive primary recovery mechanisms, resulting in rapid reduction in reservoir pressure and recovery of quantities of sand with oil.      A gravity-drainage assisted steam flooding process for recovery from thin viscous reservoirs uses a single horizontal wellbore. Steam is injected through tubing penetrating the reservoir to condition and heat the wellbore producing oil and reservoir fluids. After a period of steam circulation, production is constrained and steam injection is continued to initiate an active steam chamber. Fluid withdrawal is resumed while pressure is maintained. Steam injection is continued to cause the expansion and propagation of the active steam heated volume. As steam flows into the reservoir under gravitational counter current flow and pressure drive, heated oil, steam condensate and reservoir fluids drain and are pumped to the surface.

Abstract: La présente invention concerne une classe de polymères solubles caractérisés par un squelette en barre rigide qui, lorsqu'il est utilisé pour l'extrusion-fusion de films, subit un processus d'orientation automatique faisant que le squelette du polymère prend une orientation plus ou moins parallèle à la surface du film. Cette orientation dans un même plan donne un film à biréfringence négative. La sélection des substituants dans la chaîne du squelette du polymère permet de moduler le degré d'orientation dans un même plan, et donc l'amplitude de la biréfringence négative, par variation de la linéarité et de la rigidité du squelette de la classe de polymères, qui inclut les polyesters, les polyamides, les poly(amides-imides) et les poly(esters-imides). L'accroissement de la linéarité et de la rigidité du squelette du polymère permet d'accroître le degré d'orientation dans un même plan ainsi que la biréfringence négative qui lui est associée. Par contre, la diminution de la linéarité et de la rigidité du squelette du polymère permet de diminuer la biréfringence négative.

Abstract: Provided is a new method as well as a related installation to realize the extraction of vegetable juice from a vegetable residue and/or a vegetable peelings residue, of which the latter was lost for human consumption up to now as it was assumed that no more vegetable juice could be extracted from it. Surprisingly, tests demonstrated that it was nevertheless possible to technically extract the useful quantity of vegetable juice almost entirely from the residue. In particular, this purpose is achieved by using e.g. a fruit squeezing unit, known per se, with which under normal conditions only very juicy fruits are squeezed.
