摘要： A method of operating a cyclic solvent-dominated recovery process (CSDRP) for recovering viscous oil from a subterranean reservoir of the viscous oil. 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. Aspects of the invention relate to the particular volume of solvent injected in each cycle, when to switch from production to injection, the injection pressure to be used, the production pressure to be used, and to middle and late life operation.

摘要： The present invention relates generally to in situ hydrate control during hydrocarbon production when applying a recovery method utilizing cyclic injection of light hydrocarbon solvents. Hydrate formation is limited by creating an energy reserve within a hydrocarbon reservoir adjacent to the wellbore. A heated solvent is injected during an injection phase of a cyclic solvent dominated recovery process to form a heated region adjacent to the wellbore at the end of an injection cycle. The energy reserve is used to act against the evaporative cooling effect caused by subsequent production and associated depressurization to maintain reservoir conditions outside of hydrate formation conditions. In situ conditions are estimated and injected energy amounts are controlled.

摘要： To recover in situ viscous oil from an underground reservoir, electricity is conducted through the underground reservoir by at least two electrodes in an amount that would, in the absence of solvent injection, cause water in the reservoir to vaporize adjacent to the electrodes, and injecting solvent into the reservoir to mitigate water vaporization adjacent to the electrodes by vaporizing solvent in this region. Oil and solvent are produced through one or more production wells.

摘要： A method is described for recovering viscous oil such as bitumen from a subsurface formation. The method involves creating an artificial barrier in a subterranean zone above or proximate a top of the subsurface formation. The barrier is largely impermeable to fluid flow. The method also includes reducing the viscosity of the viscous oil and mobilizing hydrocarbons into a readily flowable heavy oil by addition of heat and/or solvent. Heating preferably uses a plurality of heat injection wells. The method further includes producing the heavy oil using a production method that preserves the integrity of the artificial barrier.

摘要： Methods for recovering viscous oil include receiving electrical power from an electrical grid fed by at least one fluctuating electricity supply. The methods also include using at least a portion of the received electrical power to heat a first fluid stream using an electrical heater. The methods also include heating a second fluid stream with a fired-heater using a combustible fuel. The methods further include using both the first and second heated fluid streams to aid oil recovery. In accordance with these methods, the heat output of the electrical heater is adjusted during production operations to at least partially match an estimated mismatch between electrical power supply from and demand on the grid. At the same time, the heat output of the fired-heater is adjusted to at least partially compensate for fluctuations in the electrical heater heat output.

摘要： Described is a way to reduce solvent usage in solvent-dominated oil recovery processes through the use of an emulsion. Injection of an emulsion into an oil reservoir is performed as an alternative or supplement to solvent injection to minimize solvent usage per unit amount of oil recovered. The emulsion may contain solvent and the solvent may form an external-phase of the emulsion. A solvent-external emulsion may be injected and formed using an aqueous liquid or a gas as the internal phase. The emulsion may be an aqueous-external, vapor-internal emulsion with solvent being injected separately or simultaneously. Polymer may be added to viscosify the emulsions and use them for flow diversion in a solvent-dominated process.

摘要： The present disclosure includes the use of grids composed solely or in part of a set of contiguous cells having six or more principal flow directions within a single layer is disclosed for use in numerical simulation. The grids are particularly well-adapted for use in modeling flow in hydrocarbon-bearing reservoirs where fingering or channeling is experienced. Methods of constructing a bisected periodic grid and a substantially constant width radial grid in connection with the present disclosure are also provided. The problem of grid orientation effects is lessened by providing grids with an increased number of principal flow directions, typically six or more. The improved grids may be used in many preexisting simulators.
