摘要： A variable flow resistance system for use in a subterranean well can include a flow chamber through which a fluid composition flows, the chamber having at least one inlet, an outlet, and at least one structure spirally oriented relative to the outlet, whereby the structure induces spiral flow of the fluid composition about the outlet. Another variable flow resistance system for use in a subterranean well can include a flow chamber including an outlet, at least one structure which induces spiral flow of a fluid composition about the outlet, and at least one other structure which impedes a change in direction of flow of the fluid composition radially toward the outlet.

摘要： A variable flow resistance system can include a flow chamber through which a fluid composition flows in a well, the chamber having an inlet and an outlet. The fluid composition enters via the inlet in a direction which changes based on a ratio of desired to undesired fluid in the fluid composition. A well system can include a variable flow resistance system through which a fluid composition flows between a tubular string and a formation, the flow resistance system including a flow chamber through which the fluid composition flows, with only one chamber inlet. The fluid composition flows more directly from the inlet to an outlet as a ratio of desired to undesired fluid in the fluid composition increases. Another flow resistance system can include at least one structure which influences portions of the fluid composition which flow circuitously between the inlet and the outlet to maintain such circuitous flow.

摘要： Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.

摘要： A method for filling an annular area within a wellbore penetrated by a subterranean formation is provided. The method includes the steps of: (a) introducing a proppant into a wellbore to form a gravel pack of the proppant, wherein a specimen of the proppant has a non-globular and non-fibrous shape, and wherein the shape is further selected to provide the proppant the ability to bridge together such that the proppant has a maximum bridging span of at least 3 times larger than a largest overall dimension of the proppant specimen, where the maximum bridging span is the largest outlet hole diameter that the proppant can bridge under the weight of gravity; and (b) passing fluid through the gravel pack.

摘要： Structures can be formed downhole by accumulating already existing materials and/or materials introduced into a well to perform a specified function. The formed structures may be used to obstruct fluid flow of production or injection fluids, carry mechanical loads, control electrical or magnetic properties of components, mechanically actuate a component, as well as others. The materials may be induced to form the specified structure, such as by application of a potential downhole. For example, electrical, magnetic, sonic, biological potentials, or a combination thereof may be established downhole to form specified structures in specified locations to perform specified functions.

摘要： The disclosure describes a method and apparatus for effectively communicating data along an acoustic transmission path. The method comprises driving an acoustic transmitter to send a data signal along the acoustic transmission path, where the signal is distorted by ambient noise. The distorted signal is input to a spaced apart plurality of sensors so that consequent time-delayed signals provide reinforcement of the basic signal and attenuation of the ambient noise component when combined.

摘要： An energy storage device for powering a downhole tool may be heated to an effective temperature to improve the operability of the energy storage device. The energy storage device may comprise, for example, a primary battery, a secondary battery, a fuel cell, a capacitor, or combinations thereof. The effective temperature to which the energy storage device is heated may be greater than an ambient temperature in the wellbore near the energy storage device. The energy storage device may be heated using various heat sources such as an ohmic resistive heater, a heat pump, an exothermic reaction, a power generator, a heat transfer medium, the energy storage device itself, a downhole tool, or combinations thereof. A thermal conductor may extend between the heat source and the energy storage device. Further, a thermal insulator may at least partially surround the heat source and the energy storage device.
