  ABSTRACT

  Optimizing Artificial Lift Operations Through the Use Of Wireless Conveyed Real Time Bottom Hole Data

  The use of an innovative wireless bottom hole pressure/temperature telemetry acquisition system in artificial lift operations can dramatically improve efficiency and optimize fluid producing rates in those wells. The tool is installed into the producing well in the vicinity of the perforations, measuring and transmitting the producing bottom hole pressures and temperatures to the surface for instantaneous control of the surface pumping motor speed. This insures the lowest possible fluid level back pressures, thus allowing for the highest possible fluid entry into the wellbore from that reservoir's capacity. Operating costs per barrel are lowered since the maximum oil production can now be realized from existing wells.
  

  The telemetry tool is deployed with standard slickline equipment and is installed inside a well in a manner similar to ordinary pressure recorder tools. Several unique advantages of the tool are:
  

  1. no moving parts
  2. no wireline to the surface
  3. real time measurements of bottom hole data
  4. slickline retrievable.

  Future versions of the acquisition system tool will improve operating efficiency in the following ways:
  

  • Temperature monitoring and control of perforation scaling, tubular waxing. And tubular hydrating plugs.
  • Provide data necessary to create diagnostically predictive IPR curves through monitoring of reservoir in-flow rates.
  • Enabling early warning of water encroachment or lensing through fluid resistivity monitoring.
