A NEW APPROACH TO
Pumping Unit Optimization
SLOW JACK™ is a simple yet effective means to reduce strokes per minute (SPM) in order to match the inflow of your formation. The SLOW JACK™ unit installs in series with the existing belt drive on conventional Beam Pump Units. The double belt arrangement increases the mechanical advantage and allows the operator to adjust SPM below the normal limits while maintaining current production. Reduction of SPM results in substantial savings.
Fewer rod failures
Fewer tubing failures
Longer pump runs
Dramatically increased pump efficiency
Less surface equipment failures
Lower horsepower requirements
In the past, a faster stroke was used to create quick compression inside the pump to compensate for gas interference. In addition, the practice of "tagging bottom" was commonly used in an attempt to jar the traveling valve ball off seat in the event of gas lock. If gas lock occurs at the lower SPM possible with the SLOW JACK™, a quality gas lock breaker may be installed in the pump to mechanically eliminate the problem.
FEWER STROKES PER MINUTE PRODUCE SAVINGS IN APPLICATIONS WHERE FLUID PRODUCTION IS LIMITED
- Every 2 strokes per minute reduction saves over 1,000,000 strokes per year.
- Less wear and tear on ALL moving parts above and below surface and substantial power savings.
- As SPM is reduced, down hole stroke becomes more predictable and synchronized with surface equipment. (Less rod failures)
- Lower differential across the standing valve. (Less gas break out in the pump)
- Gas lock problems are eliminated by installing a quality "Gas Lock Breaker"*
- Better gas separation in annulus and no lost production
- A mechanical device installed in the pump which makes it impossible to gas lock if spaced properly.
- Less movement of unanchored tubing. (Reduced annular foaming)
- Production can be controlled in unstable formations (Less sand influx)
THE APPLICATION OF SLOW JACK™ ON PROPER CANDIDATES
RESULTS IN LOWER LIFTING COSTS AND AN EXTENSION OF ECONOMIC LIMITS.
