In 1996 as Triconn (a sister company to Conn Pumps) started doing pump to surface jobs there were too many occasions when the pumps would "sand off" which stopped the job. Because Triconn could not release the anchor and long stroke the tubing and did not have a pump and tank it would mean that the rig would have to come back onto the well and pull the pump and run another. Although this was not the fault of Triconn they soon realized that unless they could ensure trouble free jobs that their clients would probably just use the rig. The designers at Conn decided that they could build a better pump to surface tool and proceeded to do just that.

The first Conn Pump produced 3500 barrels of sand from 16 different wells and the barrel at the end of this period did not have a scratch on it.

Further enhancements resulted in pumps that would not gas lock in foamy heavy oil and would produce high suction and discharge pressures. Additional features in the Conn Pump prevented "sanding off" and floating on the down stroke.

The changes made such an improvement that a U.S. and Canadian patent was applied for and granted in the summer of 2000.

Initially the pump to surface tools were rented on a relatively short term basis to do sand clean outs on wells. The tubing was stroked with a work over rig or a Triconn portable pump to surface unit.

Oil companies observed that when the tools were used to produce wells (to clean sand) that production rates were higher than progressive cavity pumps and that much higher concentrations of sand in oil could be produced.

As a result of the above observations Husky Energy purchased a Conn pump to surface tool to be used as a permanent production pump. Along with the Conn Pump a hydraulic pump jack was used to stroke the tubing attached to the pump downhole.

This was so successful that more pumps were purchased from Conn.

As of 2003 a substantial number of pumps have been sold to oil companies producing heavy oil in Western Canada.

Further improvements in this type of pumping system were made through the introduction of a side entry spool at surface which allow a coiled tubing unit to run down into the tubing and do a sand clean out in the event that sand settled on top of the pump traveling valve due to a sand slug.

Conn Pumps are sold and serviced in Canada through an agent - distributor located in the heart of the Canadian heavy oil industry.

The Present
Conn Pumps has since introduced a new product which greatly improves oil production and well efficiency. The Cyclone Plunger system. The patented design of this unique system represents a true advancement in down-hole pump technology. Sand, grit, iron sulfide, and other fines which normally contaminate the produced oil and water can now quickly pass through the pump assembly. No longer are residual concentrations of these particulates allowed to collect between barrel and plunger.
