摘要： Described is a method of operating a cyclic solvent-dominated recovery process (CSDRP) for recovering viscous oil from a subterranean reservoir of the viscous oil to enhance recovery effectiveness. The cyclic solvent process involves using an injection well to inject a viscosity-reducing solvent into a subterranean viscous oil reservoir. Reduced viscosity oil is produced to the surface using the same well used to inject solvent. The process of alternately injecting solvent and producing a solvent/viscous oil blend through the same wellbore continues in a series of cycles until additional cycles are no longer economical. Conventionally, the solvent composition remains constant over time within each injection cycle and among cycles. In the present method, by contrast, the solvent composition is varied over time thereby providing operational benefits as described herein.

摘要： A method of cleaning fouled vessels in the paraffinic froth treatment process (PFT). The foulant comprises asphaltenes. Foulant is at least partially removed from a surface of a vessel or conduit used in a PFT process by spraying a liquid against the foulant on the surface to physically remove at least a portion of the foulant from the surface. The liquid may be a PFT-compatible liquid, water, or a combination thereof. The method may be effected in the substantial absence of a foulant-dissolving agent.

摘要： A method of establishing fluid communication between a first point and a second point within a subterranean reservoir includes injecting a first penetrating liquid at a first injection pressure and at a first injection temperature into the subterranean reservoir at the first point, and establishing fluid communication through a heavy-oil containing region by allowing the first penetrating liquid to penetrate into and completely through the heavy-oil containing region between the first point and the second point. The first penetrating liquid temperature of the first penetrating liquid remains at or below the first injection temperature within the subterranean reservoir, and the first penetrating liquid is configured to dilute heavy oil, and comprises a first penetrating liquid polar compound that is at least partially miscible with water.

摘要： A method of recovering heavy oil from a subterranean heavy oil reservoir. The method includes conducting an exothermic chemical reaction of feedstock chemicals to produce a reaction product that that is a first solvent and injecting an injected solvent including the reaction product into the subterranean heavy oil reservoir. The injected solvent has an injected solvent temperature equal to an elevated temperature resulting from heat generated by the at least one exothermic chemical reaction and the injecting occurs before the injected solvent temperature has decreased to an ambient reservoir temperature.

摘要： A use of a fluorocarbon polymer as a surface of a vessel or conduit in a paraffinic froth treatment (PFT) process, for reducing fouling. The foulant comprises asphaltenes. The surface has an average water contact angle of greater than 90 degrees, a standard deviation of water contact angles divided by the average water contact angle of less than 0.1, and impurities of less than 1000 ppmw. The fluorocarbon polymer may be a polytetrafluoroethylene (PTFE)-based polymer. The surface may be substantially free of colorants, fillers, and plasticizers.

摘要： Methods and systems for recovering heavy oil, such as bitumen, by steam assisted gravity drainage (SAGD) from subterranean formations having a water and/or gas containing layer overlying a heavy oil containing layer. A fluid blocking agent is injected into the water and/or gas containing layer above at least one pair of horizontal wells. The blocking agent undergoes a change of density, viscosity or solidity when elevated to a temperature between an initial ambient reservoir temperature and 175 degrees by heat from steam used in the SAGD process, thereby creating a seal within the reservoir above the at least one pair of horizontal wells limiting or preventing movements of fluid through the seal.
