Abstract: A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.

Abstract: A rotary gear box for a rotary drill rig having a rotary joint that includes a first conduit having a first end portion defining an exit, a second conduit having a second end portion defining an inlet, and a sealing arrangement positioned radially between the first end portion of the first conduit and the second portion of the second conduit. The second conduit is rotatable relative to the first conduit and is arranged coaxial with the first conduit. The first end of the first conduit is received within the second end of the second conduit such that the exit of the first conduit is downstream from the sealing arrangement.
