Summary: The WSI Super Life 575 Polymer packing was seeing over 86,953 feet of polished rod movement per day. This equates to 1000% increase in life over previous packing. A case study of similar run times was also conducted using the NEW WSI Super Life 575 Polymer packing on several wells in Drayton Valley, Canada. The Super Life 575 Polymer packing lasted on average of 7 times longer than previous packing including:
High Temp Brass
While all well conditions were not provided by the customer we do know that all wells in this area contained up to 2% H2S with well pressures up to 500 PSI, and well temperatures up to 175F. Strokes per minute ranged from 5-7 SPM with 120” stroke length.
