Extending The Run Life of A Long Stroke Pumping Unit By Running Coiled Rod vs Conventional Stick Rod

Operators have been challenged in designing rod pumping solutions for the life of the well in deviated, horizontal and S curve wells. Overcoming frictional side loading in high-rate producers converting earlier from ESP to rod pumping. The first 6 months of the conversion is the most critical time where operators want to reduce the cost of ESP workovers going to rod pumping earlier. The challenge is rod and tubing wear or corrosion enhanced rod ware, produced solids and gases. Long Stroke pumping units have proven to address some of these problems yielding higher production rates at slower SPM’s, however, designing the rod string with continuous rod can improve the MTBF’s by reducing the overall coefficient of friction while decreasing turbulent flow. There are benefits operators can take advantage of including landing the pump in the curve. This paper will discuss case proven case studies where the combination of coiled rod and LSPU’s have been successful, converting earlier from ESP to rod lift.
