Abstract: An artificial lift system for use in a wellbore comprising a torsion clamp connected to an electric submersible pump. The torsion clamp comprises a mandrel, a splined sleeve, a stop, a bypass sleeve, and an adjustable bracket. The mandrel has splines that mesh with splines formed on the sleeve. The mandrel also has a coupling that connects to a coupling of the stop. The adjustable bracket is configured to connect the bypass sleeve to the splined sleeve.

Abstract: Methods and apparatus for sensing wellbore conditions in artificial lift wells using low profile sensors that are installed on down hole production equipment that makes them easier to install and retrieve. In one embodiment, low profile sensors are installed on a rod string making their insertion and removal much easier than it would be if they were mounted on production tubing. The sensors can be attached directly to the rod string or can be attached to a cable that is attached to the rod string. The sensors can transmit their data electrically through the cable or through the rod string. Alternatively, the sensors can transmit their data acoustically through the rod string.
