Abstract: An apparatus that is usable with a well includes a body, a blocking member, a sensor, a radially expandable element and a controller. The body includes a longitudinal passageway that extends through the body, and the blocking member is disposed in the passageway to check fluid from flowing in a predefined direction through the passageway. The sensor is disposed on the body to sense a property of an environment of the string as the object is being communicated through the passageway; the radially expandable element is disposed on the body; and the controller is disposed on the body to selectively autonomously control the expandable element to land the body in a downhole restriction in response to the sensing.
Abstract translation: 可用于井的装置包括主体，阻挡构件，传感器，径向可扩展元件和控制器。 主体包括延伸穿过主体的纵向通道，并且阻挡构件设置在通道中以便检查流体沿预定方向流过通道。 当物体通过通道传送时，传感器设置在身体上以感测弦的环境的特性; 径向可扩张元件设置在主体上; 并且所述控制器设置在所述主体上，以响应于所述感测选择性地自主地控制所述可扩张元件以将所述身体降落在井下限制中。

Abstract: A completion string includes at least one isolation packer positioned between well zones of a plurality of well zones, and a sand control assembly and a circulating assembly each disposed uphole of a washdown shoe in the bottom-most well zone. A top well zone includes a return valve assembly, a production packer, and a second circulating assembly and a second sand control assembly downhole of the production packer. The completion string also includes an outer string spanning from the bottom-most well zone to the top well zone, and an inner production string concentrically arranged within the outer string, creating an inner-annulus between the outer string and inner production string. The inner-annulus is continuous from the washdown shoe to the return valve assembly, and the inner production string includes a production valve disposed between the sand control assembly and the circulating assembly in each of the bottom-most and top well zones.

Abstract: A technique facilitates intervention operations in many types of wells including horizontal, multi-zone wells. According to an embodiment, a completion is deployed in a borehole, e.g. a deviated wellbore. The completion comprises a side pocket mandrel having a docking station. In some embodiments, the completion may comprise a plurality of the side pocket mandrels A device, such as an electrically powered device, is removably deployed in the docking station. When the docking station receives the electrically powered device, an inductive coupler or other suitable electric coupler may be used to provide power to the electrically powered device while deployed in the docking station. The electrically powered device also is configured for engagement with a tool which enables an intervention operation by simply removing and replacing the device via the tool.

Abstract: A technique facilitates collecting data, related to a fracturing, run-in-hole, or pull-out-of hole operation. A frac plug is provided with electronics for obtaining the desired information related to the operation. For example, the frac plug may be constructed with electronic sensors, a digital storage device, and a power supply or other power related equipment. Depending on the application, the frac plug may be a composite frac plug, degradable frac plug, dummy frac plug, or other suitable frac plug. Retrieval of the information obtained may be done via coupling with an associated device, e.g. inductive or physical coupling, by utilizing a broadcast transmitter/receiver, by physical retrieval of the storage device, or by physical retrieval of the dummy frac plug.
