Abstract: The disclosure presents systems and methods for refurbishing an artificial gas lift plunger of a gas well system. According to the embodiments described herein, the systems and methods can remove a portion of a plunger body of a cylindrical artificial gas lift plunger of a gas well system. The removed portion(s) of the plunger body can cause the plunger body to be radially symmetric with a uniform body thickness along the length of the plunger body. Further, body material can be deposited onto the plunger body, substantially adhering to the plunger body and forming an increased thickness of the plunger body. Moreover, body material can be removed from the plunger body to cause a substantially uniform thickness of the plunger body.

Abstract: Embodiments of the present disclosure provide systems and apparatus for generating power from pressurized natural gas. The system may include an on-site pressure turbine for using some of the available energy of the pressurized natural gas to power an air compressor and/or electric generator. The turbine is driven by the expansion of natural gas due to a pressure differential and/or by the velocity of natural gas as it travels through a pipeline. In some embodiments, the turbine output is used to generate compressed air, which is used on-site to power pumps and switches. In some embodiments, the turbine output is used to generate electricity, which is then used on-site to power communications equipment and sensors. In some embodiments, a gear reduction system is used to adapt the turbine output to useful levels.
