Hydraulic Pumping Units

2.00 Examine HPU’s in Production Operations• HPU’s have proven to reduce downhole failures in other 

area’s• HPU’s offer numerous advantages over BPU’s• HPU’s  can replace higher volume PU’s for the long term• HPU’s offer greater operating flexibility for the long term

Another Operator’s Perspective

Operators CommentsRod pump system too large Tried reduced pump sizesDifficult to obtain correct sizingSpeed x stroke length changes dangerous and expensivePulling units and crews – long lead timeNeed a change of surface equipment to obtain slower stroke speed and stroke length – over pumping is a problem

A SolutionHydraulic PU’s vs. Conventional PU’s

• Safety• No rotating counter weights• No pinch points• No need for fencing around the PU

• Reduced rod and pump wear• Easy to tag bottom• Easy to change SPM• Smaller foot print• Reduced down hole failures 

• Fewer workovers• Adapts easily to dual casing wells

44.5% Reduction Over all benefit or reduced strokes• Less  rod failures  ‐ reduced rod reversals• Less rod wear – slower travel, less friction, less stacking at 

the btm• Lower pump intake rate may reduce sand issues• Pump ware is spread out over a longer distance
