摘要： A production system and a frac sleeve assembly of a frac assembly of the production system. The frac sleeve assembly includes a funnel section that reduces in diameter in a direction of an outlet of the frac assembly, a throat section having a selected diameter, and a ball seat at an intersection of the funnel section and the throat section for receiving a ball. When seated in the ball seat, an entire portion of a ball extending into the funnel section is exposed to disintegrating fluid in the funnel section.

摘要： A fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering towards the inlet. The flow control body, in use, causes a fluid flowing through the fluid channel to flow into an annular fluid flow path within the fluid channel. The annular fluid flow path has a geometry selected based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： 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.

摘要： An embodiment of a fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having a first surface and a second surface opposing the first surface and having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering toward the inlet. The body, in use, causing fluid flowing through the channel to diverge into at least a first path between the first surface and a first side of the body, and a second path defined by at least by the second side of the body. A geometry of the first path and the second path selected is based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： A packer assembly includes a tubular having a surface, a gauge ring provided on the surface, a back-up ring positioned adjacent the gauge ring, a packer element arranged adjacent to the back-up ring, an expansion ring arranged adjacent to the gauge ring, the expansion ring including a step portion, and a support ring arranged axially between the back-up ring and the expansion ring. The support ring includes a step feature. The step portion and the step feature are selectively engaged with expansion of the packer element to form an interlock feature that substantially limits rocking of the expansion ring.

摘要： A downhole flow control configuration including a housing, a converging-diverging flow path in the housing, the flow path including a first portion including an inlet, a converging section, and a throat section, the first portion preferentially passing a portion of a fluid having a greater subcool, and the converging-diverging flow path further including a second portion comprising a diverging section that recovers fluid pressure lost in the converging section and the throat section, and an outlet and an elongated helical flow path connected to the outlet of the converging-diverging flow path, the helical flow path producing a pressure drop in a fluid flowing therein during use.

摘要： A backup ring assembly has a plurality of radially offset ring members including an outermost ring member formed from plurality of axially extending segments. Each of the plurality of axially extending segments includes an outer surface. A first interlock member support is coupled to the outer surface of one of the plurality of axially extending segments of the outer most ring member. A second interlock member support is coupled to the outer surface of an another one of the plurality of axially extending segments of the outermost ring member. An interlock member includes a first end supported at the first interlock member support and a second end supported at the second interlock member support. The interlock member restrains radially outward expansion of the ring and circumferential expansion of a gap extending between the one of the axially extending segments and the another one of the axially extending segments.
