A mandrel in production tubing within a well has a side pocket with an inlet port for connection to an upper control line segment that extends upward alongside the production tubing. An outlet port is below the inlet port for connection to a lower control line segment extending below the pocket. A filter assembly is lowered through the production tubing into the pocket. A valve at a lower end of the pocket is movable from a closed position closing the outlet port to an open position opening the outlet port. A probe mounted to a lower end of the filter assembly engages and pushes the valve from the closed position to the open position while the filter assembly is being seated in the pocket.

Embodiments of the present invention use radar technology to detect features or conditions in a well. A radar unit having an electronics subsystem and an antenna subsystem is positioned downhole in the well. The radar unit is coupled receive power from and communicate with to a surface system. The electronics subsystem generates RF signals which are provided to the antenna subsystem, generating radar wavefronts that are propagated toward areas of interest (e.g., farther downhole). The radar wavefronts may be electronically or mechanically steered in the desired direction. The antenna subsystem receives radar signals that are reflected back to the unit by features or conditions in the well. The received reflected signals are converted to electronic signals that are interpreted by the electronics subsystem of the radar unit or by the surface system to identify the features or conditions that caused the reflections.

A downhole power generator module having a body with one or more couplings that are configured to connect the body to a downhole tool string positioned downhole in a wellbore. An axial passageway is formed through the outer housing and couplings. The power generator module has a pressure-driven electric generator such as a triboelectric or piezoelectric generator positioned within the body. A port in the body enables communication of well fluids from the wellbore to the generator. Pressure changes in the well fluids are communicated to the pressure-driven electric generator, causing it to autonomously generate electric power downhole. The generated power is provided directly to other downhole tools without intervention from the surface.

Spring discs are rotationally locked to the mandrel are between pairs of actuation rings that feature a circumferential protrusion. On application of axial force release of a stored force from flexing, the protrusion engages a sloping portion of the spring disc and moves the sloping portion toward a more vertical orientation. Alternatively, a release of a stored force from flexing accomplishes the same result. Slots in the spring disc allow irregular growth to conform to surface irregularities of a surrounding surface. The discs can serve as anchors, centralizers or supports for a sealing element in a packer. Ends of fingers feature stiffeners to enhance strength. The discs can be stacked apart or together and oriented in the same or opposed directions. The can deliver an axial force when stacked and pushed toward flat and released.
