摘要： An apparatus and method for pressure testing a tubing string of a fluid production well, the tubing string being provided with a progressing cavity pump at a downhole end, which apparatus and method can be used to help determine whether the tubing string has failed or the pump has failed. The apparatus comprises a plug member connected to the rod string assembly that includes the pump rotor, such that the rod string assembly can be lowered to seat the plug member in a seat member within the tubing string above the pump, thus sealing off and isolating the pump from the rest of the tubing string, allowing pressure testing of the tubing string above the pump.

摘要： A method for recovery of oil housed in a reservoir comprising injecting an aqueous solution or slurry of a carbonate salt into a wellbore and allowing the aqueous solution or slurry of the carbonate salt to enter into the reservoir. An aqueous solution of an acid is then injected into the wellbore and allowed to enter into the reservoir. The carbonate salt and the acid are allowed to react with each other and form carbon dioxide (CO2) gas, inside the reservoir, which mixes with the reservoir oil and thereby reduces the viscosity of the oil within the reservoir. The method also provides for a rapid effervescence of carbon dioxide that may enhance oil recovery by improving oil flow to the wellbore by increasing reservoir pressure, increasing rock permeability from sand production, causing oil swelling, inducing foamy oil creation and/or removing formation skin damage.

摘要： Systems and methods for partially upgrading a produced heavy hydrocarbon resource at the production site (at the pad or a central processing facility) using indirect hydrogen addition, comprising a blender for blending the hydrocarbon with a hydrogen donator and a reactor for elevating the mixture to a temperature sufficient to hydrogenate the hydrocarbon to an API level required for pipeline specifications. The partially upgraded hydrocarbon can then be transported by pipeline to a refinery for further processing. The presence of catalysts and on-site hydrogen production equipment conventionally required for upgrading is eliminated. Further, the need for diluent which is conventionally used to enable pipeline ability of produced heavy hydrocarbon is reduced or eliminated, thus reducing the diluent freight cost and the required pipeline volume.

摘要： A method of recovering oil from an oil sands reservoir comprises first applying cyclic steam stimulation (CSS) to a series of generally horizontally extending wells in the reservoir; then applying steam assisted gravity drainage (SAGD) to at least one vertically-spaced well pair in which one well in each well pair is part of the series of wells to which CSS was applied, while producing oil from at least one single well in the series of wells. In this case, each single well is adjacent to and offset from at least one of the well pairs. The method can then further comprise applying a SAGD blowdown to an injector well of each well pair and producing oil from a producer well of each well pair and from the single well to economic limit.

摘要： A method for recovering subsurface hydrocarbons, including heavy oil or bitumen, wherein a downhole steam injection phase is followed by application of heat to the near-wellbore region of the reservoir, heat being applied only during periods without steam injection. The heat application can be achieved by any number of techniques including electrical heaters, radio frequency waves, electromagnetic waves and microwaves. Numerous advantages are possible by withholding heat application during the steam injection phase. While preferred for use with cyclic steam stimulation recovery techniques, the method can be applied with other steam-based recovery techniques.

摘要： Improved SAGD methods for recovering heavy oil from underground formations. In a first aspect a method is provided for drilling, using multi-lateral drilling techniques, a series of horizontal collector wells from a vertical shaft of a production well, below and parallel to an injection well. In a further alternative to the typical SAGD configuration having injector and producer well drilled from the same end of a region under development, the production well is instead drilled at an end of a region of development opposite to an end of such region at which an injector well is drilled. Lastly, in yet another aspect, the invention comprises a method for rejuvenating an existing SAGD well pair, comprising drilling a further production well or wells at an opposite end of said formation at which an existing injector well was drilled, preferably using multi-lateral drilling techniques.

摘要： A post cold heavy oil production with sand (“CHOPS”) microbial enhanced oil recovery method comprises selecting a well having at least one wormhole and that has completed primary CHOPS production. When the reservoir does not contain enough of a gas producing indigenous microbe, an injectant is prepared comprising a gas-producing microbe, a nutrient suitable for the microbe, and a fluid base. The injectant is injected through the well and into the at least one wormhole in the reservoir; the well is shut in until pressure in the well reaches the target pressure; and then the well is produced.
