Paper: Jaren Mangum, Smith Lift, John Patterson, ConocoPhillips

In response to customer needs, Smith Lift has developed a 1 3/4 in hydraulically driven diaphragm pump that allows the operator to insert and pull the pump without pulling the production tubing. The Hydraulic Diaphragm Insertable (HDI) pump is driven by a surface hydraulic power unit, which actuates a hydraulic cylinder down hole creating positive displacement pumping action, similar to a rod pump. The HDI pump can be installed with or without seating nipples in standard 2 3/8 in (or larger) production tubing. This paper will discuss the operation and deployment of the HDI pump along with initial results from preliminary testing including solid handling, electrical efficiency, pull and run economics, and low volume/deep pump performance.
