    摘要: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with an infill well which is in fluid communication with the bottom half of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well. After the water cut of the fluids being produced from the infill well reaches 95 percent, the infill well is converted from a producer to an injector and hot water is injected into the lower portion of the formation via the infill well and fluids are produced from the production well. By this means, oil is recovered from the lower portions of the formation adjacent the production well. After water breakthrough occurs at the production well, steam is injected into the infill well and fluids are recovered from the production well. By this multi-step process involving the infill well, the amount of oil recovered from the portion of the formation in the recovery zone defined by the injection and production well is increased significantly.

    摘要: A method is disclosed for selectively reducing the permeability of water producing intervals in a hydrocarbon formation without reducing oil permeability. A soluble oil followed by water is injected into the formation to lower the residual oil saturation. The well is then produced to remove water from any oil zones before injection of an isobutyl-methacrylate solution in acetone. A slug of a non-condensable gas follows the treating solution before the shutting in of the well for up to about one day.

    摘要: The vertical or both vertical and horizontal conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with one or more infill wells in fluid communication with the bottom half or less of the formation, and producing petroleum from the infill well after steam channeling has occurred at the production well. After the water cut of the fluids being produced from the infill well reaches 95 percent, the infill well is converted from a producer to an injector and steam is injected into the infill well and fluids are recovered from the production well. When one infill well is employed in a more or less aligned arrangement between injection and production wells, the vertical conformance is improved. When one or more infill wells are positioned in an offset or nonaligned arrangement relative to each injector and producer, conformance in both the horizontal and vertical planes is improved. By this multi-step process involving the infill wells, the amount of oil recovered from the portion of the formation in the recovery zone defined by the injection and production well is increased significantly.

    摘要: Thermal oil recovery processes employing the injection of steam and/or hot water for mobilizing viscous petroleum sweep only a small fraction of the formation between the wells because of override, underride, or channeling resulting in poor vertical conformance, as well as poor horizontal conformance of the swept portion of the formation. Both vertical and horizontal conformance are improved significantly if steam is injected into a formation until channeling has begun, after which steam injection is terminated and an aqueous fluid is injected into the formation, which has a viscosity essentially the same as water and contains an emulsifying agent capable of forming a viscous emulsion in the portions of the formation where override, underride or channeling has occurred. After a small slug of emulsifying fluid has been injected, steam injection is resumed and as a consequence of the emulsion plug, moves into portions of the formation from which oil would not be recovered if the emulsion had not been injected. Multiple cycles of steam and emulsion injection may be applied to a formation to more completely sweep the full volume of the pattern. Surfactants suitable for use include organic sulfonates such as petroleum sulfonate, and solubilizing co-surfactants such as alkyl or alkylarylpolyethoxyalkylene sulfonates.

    摘要: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the recovery zone between one injection well and one producing well, with at least one infill well which is in fluid communication with no more than the bottom half of the formation. Steam or a mixture of steam and hydrocarbon is injected into the injection well and fluids including oil are recovered from the producing well until live steam production occurs at the producing well. Petroleum production is then begun at the infill well and continued until the water cut of the fluids being produced from the infill well reaches 95 percent. The infill well is converted from a producer to an injector and hot water or cold water followed by hot water is injected into thelower portion of the formation via the infill well and fluids are produced from the production well. By this means, oil is recovered from the lower portions of the formation between the infill well and the production well. After water breakthrough occurs at the production well, steam is injected into the infill well and fluids are recovered from the production well. Hydrocarbon solvent is injected either as a slug prior to steam injection into the infill well or comingled with the steam being injected into the infill well. By this multi-step process involving the infill well, the amount of oil recovered from the portion of the formation in the recovery zone defined by the injection and production well is increased significantly.

    摘要: The vertical conformance of a steam drive process is improved and steam override reduced by penetrating the zone between one injector and one producer, with an infill well located between the injector and producer which is in fluid communication with no more than the bottom half of the formation. Steam is injected into the injection well in the first phase with production of fluids from the upper 1/3 or less of the formation via the production well. A separate flow path in communication with the bottom 1/3 or less of the formation is provided in the producing well, and is used during the first phase for push-pull treatment of the formation with solvent and steam or hot water. After production via the production well is terminated, petroleum is produced via the infill well until the fluid being produced from the infill well reaches 95 percent water cut, after which the infill well is converted from a producer to an injector and hot water is injected into the lower portion of the formation via the infill well and fluids are produced from the production well. After water breakthrough at the production well, steam is injected into the infill well and fluids are recovered from the lower 1/3 of the production well.

    摘要: A system assigns a plurality of printing or other information distribution jobs to a plurality of medium units for processing. The system includes an input interface module receiving from customers, specification data files each specifying an information display job in a specification file signal. The input interface module selects for each specification data file at least one medium unit suitable for performing the information display job in the specification data file and forms for each specification file signal, a job description format (JDF) file recording the information in the specification data file and the identifier of each selected medium unit. The input interface module provides the JDF file in a JDF file signal. An application interface module receives each JDF file signal, and deletes all but one of the at least one medium unit identifiers specified in the JDF file, and provides a modified JDF file signal based on the JDF file signal. A job aggregation module within the application interface module receives each modified JDF file signal and transmits the data content therein to the medium unit specified in the modified JDF file signal.

    摘要: Method for forming a gravel pack in-situ about a horizontal well in a sandy formation. The gravel pack is formed in two separate steps so that part of the pack will function as a foundation for slidably inserting and supporting the well liner. Thereafter, the remainder of the pack is completed about the liner by introducing a gravel slurry that accumulates on the foundation and about the liner.
