摘要： The invention is a method of recovering oil bypassed by a steam override zone. First, the production well is drilled below the oil producing zone into an underlying interval. The well perforations in the oil producing zone are closed off. The underlying interval is fractured to establish fluid communication between the underlying interval and the oil producing zone. The production well is completed for production through the fractured portion of the underlying interval. Finally, the steamflood is controlled to increase the pressure in the oil producing zone and drive the oil and steam downward to the new perforations in the underlying for production.

摘要： A well completion, and method for recovering heavy hydrocarbons or bitumen from a subterranean formation. The completion includes a well liner which lies in a generally horizontal disposition within a hydrocarbon holding substrate to define the main or primary well. A secondary well which extends to the surface intersects the main well to communicate therewith. Said secondary well includes means to conduct a stream of hot stimulating fluid into the main well. A fluid impervious barrier or flow diverter means positioned within the main well between the injection end and the production end, establishes a pressure differential across the barrier. The barrier urges stimulating agent into the substrate at a desired location, thereby creating a heated path along which the bitumen emulsion flows toward the well's production end. Means is provided in the secondary well to position the impervious barrier from one end of the main well to the other.

摘要： Oil is produced from a steeply dipping subterranean reservoir containing high viscosity petroleum by injecting a fluid comprising steam into the lower portion of the reservoir and withdrawing the oil from production wells in an intermediate portion of the reservoir while injecting a fluid such as cold water into the updip portion of the reservoir to prevent loss of steam vapor therethrough.

摘要： Method and apparatus for recovering hydrocarbons from a subterranean formation in which a well completion, including a well liner, lies in a generally horizontal disposition within the hydrocarbon producing layer. The liner encloses conduit means for delivering a stream of a hot stimulating agent to the well's remote or injection end, and means for regulating the production of bitumen emulsion from the production end. A fluid impervious barrier is carried on and depends from the conductor means and forms a transverse fluid barrier within the liner. The conductor member is fixed within the liner whereby to serve as a means for introducing the thermal stimulating agent or medium to the substrate as well as functioning as a guide for the movable fluid impervious barrier. By adjusting the longitudinal position of said barrier, the hot stimulating agent is more effectively introduced to the substrate to improve the sweeping action thereof.

摘要： Our invention concerns a method for treating a well completed in a subterranean petroleum containing formation which will improve the rate at which steam can be injected into the formation for a steam push-pull or steam drive oil recovery method. This preconditioning process is applied to formations exhibiting very limited steam receptivity because the formation contains high oil viscosity and has high oil saturation and is completely liquid filled. The method involves injecting a heated non-condensable and oil soluble gas all in the gaseous phase into the formation at a controlled rate which will avoid permanently fracturing the formation and also avoid the immediate formation of an oil bank due to dissolution of the injected gaseous fluid into the oil. Ideally by controlling the injection rate, carbon dioxide first displaces water from the flow channels and then slowly dissolves in the oil. Steam injection can then be applied to the formation without the previously experienced loss in steam injectivity.

摘要： The disclosed invention is an apparatus for analyzing the annulus effluent of a producing well. The apparatus is designed to measure the flow rate of the annulus effluent, sample the annulus effluent and determine the quantities of each of the various phases of the annulus effluent. The apparatus is preferably mounted on a mobile vehicle and comprises a means for measuring the flow rate of the annulus effluent, a liquid vapor separator to split the annulus effluent into streams of entrained liquid and vapor, a separator to split the entrained liquid into the phases of oil and water, a sampling loop for extracting a sample of annulus effluent vapor which contains a condensor and a separator for splitting the fluid into its various phases, a means for measuring the amounts of all of the phases of the annulus effluent, and a means to record the data gathered. The apparatus is very useful in determining whether a producing well should be shut-in, worked over or left to produce "as is".

摘要： A method for determining the quality of steam flowing in a line used for steam injection, e.g. in an oil well. It has a vertical loop in the line, with an orifice in the up-flow side. The pressure, temperature and pressure drop at the orifice are measured before and after injecting a stream of water upstream from the orifice. The water stream is injected at a constant flow rate, and its temperature and pressure are measured. Using the measurements before and after the introduction of the water stream, simultaneous equations are developed related to the mass flow rate and to the heat flow rate, so that the steam quality may be determined.

摘要： A well completion, having an injection end and a recovery end, and method for recovering heavy hydrocarbons or bitumen from a subterranean formation. The completion includes a well liner which lies in a generally horizontal disposition within a hydrocarbon holding substrate. Means for carrying a stream of a hot stimulating fluid from the well's injection end such that said fluid will migrate into the substrate surrounding the liner. A fluid impervious barrier is movably positioned within the well liner between the injection end and the production end thereof, and prompts establishment of a pressure differential across the said barrier. The barrier urges pressurized stimulating agent outwardly into the substrate, thereby creating a heated path along which the bitumen emulsion flows toward the well's lower pressure production end. The barrier is adapted to be repositioned within the liner to adjust the bitumen flow path through the substrate.

The first well is placed relatively near the top of a hydrocarbon interval and the second and third wells are placed near the bottom of the interval on each side of the first well. A recovery fluid is injected into the formation through the second and third wells and hydrocarbons and other fluids are recovered through the first well.
