Usage of fiberglass sucker rods have proven to be the most efficient means of producing artificial lift wells in the Pioneer Natural Resources, Spraberry Trend Area. Fiberglass/steel designs are being installed on all new drilled wells and will remain in place for the life of the well. In this paper examples will be given of production improvements when going from an all steel to a fiberglass/steel design, various designs which decrease string weight 13 to 26%, benefits of the lighter more elastic rod and comparison of failure data. Procedures used by Pioneer will be discussed to assist operators in selecting the best design for different well characteristics.
