Abstract:
Methods and apparatus for harvesting energy while moving a tool through a well are shown and described. The harvested energy can be used by the tool to perform work once it reaches an intended location in the well, or along the way. A considerable amount of potential energy is typically lost by oilfield tools as they move down through a borehole. Methods and apparatus described herein recover and/or store some of the energy during the downward movement of the tool.
