The Value of Down-hole equipment in a plunger lift application

After 9 months of continued free-cycle plunger lift service this bumper spring and bottom hole assembly was removed to perform some well servicing.  As you will see the entire assembly is still in excellent shape.  There is no deformation of the spring or signs of stress cracking. The fish-neck is in very good shape and is not "mushroomed" out or even indented.  (Mushrooming is a slang term that is used when the fish neck deforms due to the plunger landing on it over a period of time.)
 

Well Details:
 
v Well depth 2,950 meters
v 35-40 plunger cycles per day!
Plunger Lift System was completed with a self optimizing controller
v 60.3 mm Solid Ring Penta-Cycle (Free-cycle) Plunger Lift System
 
Pentagon Optimization Services has one of the most robust down-holeassemblies in the business. The spring is a very heavy gauge springdesigned to withstand "dry tripping" of a plunger.  The fish neck onthe bumper spring assembly is hardened to prevent it from deforming and"mushrooming".    Free-cycle plunger lifts, especially two-pieceplungers, have been known to cause downhole and surface damage due tothe velocity they travel at. 
 
Unlike the surface equipment the downhole assembly is sometime out ofsight out of mind until it needs to be removed.  Most people that haverun plungers will know of a downhole problem associated with a bumperspring failures which can be very costly to repair.  So the questionthat may need to be asked”
