摘要： A frac system includes a first packer assembly having a first compression set packer and a first indexing member, and a second packer assembly arranged upstream of the first packer assembly. The second packer assembly includes a second packer, a second indexing member, a bypass inlet arranged upstream of the second packer, and a frac port arranged downstream of the second packer. The bypass inlet is fluidically connected to the frac port through a bypass flow path and is selectively opened without disengaging the second packer.

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 electro-hydraulic actuator includes a housing having an interior portion a first opening and a second opening, a transducer is arranged in the interior portion. The transducer includes a sensor operatively coupled to a signal source at the first opening. A selectively activatable valve component is arranged at the second opening. The selectively activatable valve component maintains a desired pressure in the interior portion of the housing. An actuator is operatively coupled to the transducer and operable to activate the selectively activatable valve component exposing the interior portion to a volume of fluid in response to a signal from the transducer to activate a downhole system.

摘要： A sealing device is used in a flow control apparatus, the sealing device including a static seal and a protective seal or fluid restriction. The protective seal is formed between two members formed from resilient materials being substantially resistant to wear or failure when exposed to large pressure differentials and associated jetting action. The static seal is formed using a sealing element that includes a material that is at least partially deformable, such as an elastomer or the like. The protective seal is engaged prior to engaging or disengaging the static seal in order to prevent damage to the deformable material of the static seal.
