Abstract: A drill pipe assembly includes a first drill pipe and a second drill pipe disposed in a wellbore. The first drill pipe includes a tubular wall and a threaded end at a downhole end of the tubular wall. The second drill pipe is disposed in the wellbore downhole of and fluidically coupled to the first drill pipe. The second drill pipe includes a tubular wall and a threaded end corresponding with and configured to receive the threaded end of the first drill pipe to form a connection. At least one of the first drill pipe or the second drill pipe includes an annular groove residing between a respective tubular wall and a respective threaded end. The drill pipe assembly is collapsible at the annular groove under a torque smaller than a torque required to collapse the connection.

Abstract: A drill pipe assembly includes a first drill pipe, a second drill pipe, and a tubular pipe link residing between and fluidically coupled to the first drill pipe and the second drill pipe. The tubular pipe link includes a first end and a second end opposite the first end. The first end is threadedly coupled to a threaded end of the first drill pipe to form a threaded connection. The second end is attached to the second drill pipe. The first end of the pipe link has less threads than the threaded end of the first drill pipe. At least some of the threads of the first end of the pipe link are collapsible to disconnect the first drill pipe from the second drill pipe responsive to torque to tighten the first drill pipe to the pipe link.

Abstract: A vibration sensor connected to a hydrocarbon recovery equipment operating on a surface of the Earth senses a portion of vibrations of the hydrocarbon recovery equipment when performing operations to recover hydrocarbons from a subterranean zone. The vibration sensor transmits the portion of vibrations to a vibration controller on the surface. The vibration controller is disposed on the surface of the Earth. The vibration controller compares the portion of vibrations sensed by the vibration sensor to a stored threshold vibration level associated with the hydrocarbon recovery equipment. Based on a result of the comparing, the vibration controller transmits an alert signal to an alarm system on the surface. In response to receiving the alert signal, the alarm system emits an acoustic or optical alarm signal representing the result of the comparing.
