Abstract: A production well includes a casing and encapsulated tubing positioned within the casing. The encapsulated tubing includes a conductive sidewall defining a channel for an injection fluid. The production well further includes an insulative layer surrounding the conductive sidewall. The production well also includes a controller configured to regulate flow of an electrical current through the conductive sidewall. The production well further includes production tubing positioned within the casing and configured to channel a production fluid through the casing. The insulative layer is configured to inhibit transmission of the electrical current between the conductive sidewall and the production tubing. The production well also includes at least one sensor positioned within the casing to detect downhole conditions of the production well. The conductive sidewall is configured to conduct electrical current toward the at least one sensor.

Abstract: A sensing and communication system for a gas lift well is provided. The gas lift well includes a casing, production tubing positioned within the casing, and a gas lift valve coupled to the production tubing. The sensing and communication system includes a turbine configured to rotate in response to an injected gas stream flowing through the turbine, wherein the turbine is positioned one of i) within an annulus defined between the production tubing and the casing and ii) within the gas lift valve, an alternator coupled to the turbine and configured to generate electrical power from rotation of the turbine, and at least one sensor coupled to the alternator and configured to operate using the generated electrical power.

Abstract: A solids detector may include a receptor configured to extend at least partially into a flow path of a fluid through a conduit. Further, the solids detector may include a sensor configured to receive an acoustic wave generated due to one or more solid particles in the fluid impacting the receptor. Additionally, the sensor may be configured to generate an electrical signal based on the acoustic wave. The electrical signal may be indicative of one or more impact energies of the one or more solid particles that impacted the receptor.
