Systematic solution overcomes artificial lift challenges

Operators in the liquid-rich portion of the Eagle Ford shale continue to search for the best means to optimize the long-term production after the natural flow stage ends. The challenge is to manage changes in production rate, define and manage reservoir deliverability from the stimulated reservoir volume, and increase production efficiencies. Electrical submersible pump (ESP) systems are used in the transitional artificial lift phase to provide an integrated program that maximizes production over the complete life of the well. The Eagle Ford shale play includes unique reservoir characteristics and fluid behaviors that are especially challenging in downhole conditions that include high temperatures, high gas volume, slugging, unsteady flow, paraffin, and some scale deposits that complicate artificial lift solutions. Magnum Hunter Resources and Schlumberger teamed up to implement an unconventional ESP solution as part of a systematic approach to transitional artificial lift.
