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.
