    Abstract: A system for regulating fluid flow in a geothermal energy production system includes a flow control device disposed in an injector well and/or a producer well, which are disposed in a subterranean region. The injector well includes an outflow port configured to inject a fluid into the region, the producer well includes an inflow port configured to receive the fluid from the region, and the outflow port and the inflow port are in fluid communication via one or more passages in the subterranean region between the injector well and the producer well. The flow control device is configured to restrict a flow of a fluid into the producer well based on a temperature and/or a flow rate of the fluid in the flow control device. The temperature and/or the flow rate selected to maintain a temperature of the fluid entering the producer well within a selected range.

    Abstract: A method of closing a fluid flow path in a wellbore is disclosed that in one non-limiting embodiment includes: supplying a flexible structure having a selected shape sufficient to seat on an opening of the fluid flow path, the flexible structure including pores of selected dimensions; determining seating of the flexible structure on the opening of the fluid flow path from a sensor measurement; and supplying a slurry containing a sealant to the flexible structure seated on the opening of the fluid flow path to plug the pores with the sealant to close the fluid flow path.

    Abstract: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.

    Abstract translation: 在井眼内设置封隔器的装置和方法，几乎​​不会明显减少井筒的可用面积。 井眼的外壳或衬套包含一个或多个具有增加直径的室部分的集成的套管联接器接头。 大口径包装元件被承载在增加直径的腔室部分内。 包装元件可以被选择性地致动以形成抵靠内部管状构件的密封。 因为包装元件位于套管联接器的腔室部分内，所以可以设置封隔器，同时在壳体内节省可用的横截面积。

    Abstract: A spark-gap tool includes a plurality of electrodes, a mandrel, transductive element(s), and a force transmission configuration. Upon relative movement between components a physical distortion of one or more transductive elements occurs, whereby an electrical potential is generated. A method for powering the spark-gap tool is by physically distorting one or more transductive elements by moving components axially and/or rotationally. A method for treating a borehole is by physically distorting one or more transductive elements thereby creating sufficient voltage potential to cause an arc of selected magnitude across a spark-gap in the tool. A downhole power generation arrangement includes a first member and a second member that are movable and a piezoelectric element on one of the first member and the second member and in force transmissive communication with the other of the first member and the second member.

    Abstract: A system for diverting fluid in a borehole string includes an object configured to be deployed in the borehole string. The borehole string includes a plurality of fluid ports defining a plurality of zones along a length of the borehole string, each fluid port extending from a fluid conduit in the borehole string to at least one of: an annular region of the borehole string and a subterranean region. The object is configured to be advanced by a fluid to a fluid port to obstruct the fluid port and divert the fluid in the borehole string to another fluid port. The object includes a core portion made from a first material having a first property, and an outer portion at least partially surrounding the core portion and made from a second material, the second material being deformable and having a second property that is different than the first property.

    Abstract: A resource exploration and recovery system includes a first system and a second system extending into a wellbore. The second system includes a completion having a casing defining a wellbore internal diameter. A chemical injection tubing extends from the first system into the completion. The chemical injection tubing includes a terminal end portion. A chemical introduction system is arranged at the first system and is fluidically connected to the chemical injection tubing. The chemical introduction system is operable to deliver a chemical into the chemical injection tubing. A chemical injector assembly is mounted to the terminal end portion. The chemical injection system includes an anchor and a chemical injector valve.
