SUPER SLOW PUMPING MULTI-SPEED COUNTER SHAFT SLASHES ELECTRICAL BILLS ON OLD WELLS WITH LOW VOLUME PRODUCTION McKenzie Electric Cooperative
The first BeauTech, Inc. shaft unit called a Slow Jack™ is operating on the Panterra Eckert 2-5-4B oil location. This location is producing 15 barrels of oil and 16 barrels of water per day, from 9400 feet using a 1 1/4" pump on CMI 456 pump jack, pumping at 2.0 strokes per minute. The power cost from McKenzie Electric Cooperative before the 60 horse power unit was converted in June 1996, averaged $805 per month. The cost for the first three months was $526. This saving of $279, when applied toward the estimated installed cost of $4,000, pays out in about 14 months on energy savings alone. The producer sees the energy savings as the primary driving benefit, followed closely by reduced starting and stopping maintenance on the total unit, particularly during cold weather. The shaft assembly is using a 15 horse power motor which pulls a demand of 7.8 kilowatts, during 15 minute peaks. The monthly load factor (electrical efficiency) was 80%, which is a small improvement over the larger 60 horse power motor that pulled an 85% load factor. What we at McKenzie Electric see as benefits, are reduced power demands, high load factors and smaller facilities. This is a valuable low cost alternative to shutting in those marginal producing oil wells and looks to be a very simple low maintenance installation.

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.
