摘要： A method of acidizing a subterranean formation with a diverting agent composed of a gelled or thickened viscoelastic foam or fluid generated from (i.) an amidoamine oxide gelling agent and (ii.) an acid or foam, water and/or brine. The gelled or thickened foam or fluid may be generated in-situ or introduced directly into the formation by mixing of the amidoamine oxide gelling agent and acid or foam, water and/or brine. As the acid spends, the acidizing fluid thickens. When the acid is further spent, the fluid viscosity declines eventually returning to a low viscosity state, allowing for easy cleanup. The process allows for selective acidizing of less permeable zones of the formation and more uniform stimulation of the hydrocarbon bearing formation.

摘要： A method of fracturing a zone of a subterranean formation penetrated by a well bore is shown in which a gelable fracturing fluid is formed by combining an aqueous base fluid and a hydratable polymer. A transition metal crosslinker is added to the aqueous base fluid for crosslinking the hydratable polymer to form a gelled fluid of sufficient viscosity to facilitate fracturing of the formation. A proppant can also be added to the gelable fracturing fluid. The gelled fluid and proppant are then injected into the well bore and into contact with the formation under sufficient pressure to fracture the formation. The gelable fracturing fluid has incorporated therein a delayed release breaker comprising a complex multivalent chelating agent that is released slowly over a period of time to compete with the polymer for the transition metal crosslinker, thereby reducing the viscosity of the fluid.

摘要： Methods useful in improving hydrocarbon recovery from subterranean formations using relative permeability modifier (RPM) macromolecules are described. The RPMs are typically crosslinked RPMs having K-values from 250-300 which, when injected into an injector well associated with a producer well, redirect the production water so as to improve the injection profile of the well and simultaneously improve hydrocarbon recovery from the producer well.

摘要： The present invention relates to compositions of aqueous compositions comprising relative permeability modifier (RPM) macromolecules and one or more formation damage control additives, for use in treating hydrocarbon-producing wells, formations, and equipment, as well as methods for the use of such compositions. Such compositions, comprising the RPM macromolecule and the one or more formation damage control additive, such as a scale control agent, can result in the formation of a composition wherein the components exhibit a “synergistic” effect, whereby the ability of the formation damage control additive to prevent formation damage is enhanced relative to the use of the same additive separately.

摘要： A system for enabling a user of a communication device to both handle an incoming call and originate an outgoing call without having to touch the communication device, by way of exchange of voice messages with the communication device. The system is operative for receiving a signal produced by a microphone associated with the communication device and for processing this signal in an attempt to detect at least one of a plurality of spoken commands potentially contained therein. The plurality of spoken commands comprises at least one spoken call handling command and at least one spoken call origination command. In response to detecting a spoken call handling command, the system causes handling of an incoming call destined for the communication device in accordance with the detected spoken call handling command. In response to detecting a spoken call origination command, the system causes an attempt to establish an outgoing call using the communication device in accordance with the detected spoken call origination command.

摘要： A draft force sensor is provided for a coupling member coupled between a towing vehicle and a towed earth engaging implement, such as a scraper. The draft force sensor includes first and second bores extending through the coupling member. Each bore has a horizontal axis which extends perpendicular to a main fore-and-aft axis of the coupling member. The second bore is positioned above the first bore and spaced apart from the first bore. Each of the bores is surrounded by an outer cylindrical wall. Four electrical strain gauges are spaced apart and placed on the wall of each of the bores. A center line bisects an axis line which extends between the axes of the first and second bores. The axis of each bore is spaced apart from the center line by a distance which is less than a diameter of the bores. The strain gauges are connected electrically in a circuit which generates a draft force signal in response to draft forces applied to the coupling member.

摘要： A thermal insulating packer fluid contains an organic solvent of low thermal conductivity and a gelling agent which is hydratable in the solvent. The composition is capable of inhibiting unwanted heat loss from production tubing or uncontrolled heat transfer to outer annuli. The viscosity of the composition is sufficient to reduce the convection flow velocity within the annulus.

摘要： A towed scraper control system automatically lowers the scraper blade to a working position at the start of a scraping operation according to a certain method. The method includes sensing a ground speed of the vehicle and sensing a draft force applied by the scraper to the vehicle. With the vehicle pulling the scraper at or near a target ground speed over terrain with the blade positioned above a surface of the ground, the blade is automatically lowered with respect to the scraper frame at a first rate until the blade begins to engage the surface of the ground. Thereafter, while the vehicle continues to move forward at or near the target ground speed, the blade is lowered with respect to the frame at a second rate and for a duration related to the sensed ground speed so that lowering of the blade stops when the scraper wheel begins to enter a cut produced by the blade. With the blade fixed with respect to the scraper frame, the scraper is moved forward at the target ground speed for a distance determined as a function of the sensed draft force. Thereafter, the blade is raised with respect to the frame at a rate which matches a lowering rate of the wheels as they descend along the cut, and the blade is raised at this matching rate until the position of the blade matches the position of the blade after the first lowering step. Preferably, the second rate is slower than the first rate.
