SLOW JACK (TM) is a simple
yet effective means to reduce strokes per minute (SPM) in order to match the inflow of
your formation. The SLOW JACK (TM) 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 TM
ON PROPER CANDIDATES RESULTS IN LOWER LIFTING COSTS AND AN EXTENSION OF ECONOMIC LIMITS.
