Smith Lift Hydraulic Diaphragm Insert Pumps

Smith Lift hydraulic diaphragm insert pumps (HDIs) are positive-displacement single-acting diaphragm pumps. They are hydraulically driven from a surface power unit. An electrically powered variable-flow surface pump circulates hydraulic working fluid, driving the downhole pump, which lifts the produced fluid up the production tubing and through the casing annulus. Elimination of the downhole electric motor and submersible pump cable means that HDIs can pump off without damaging the downhole tool.

These pumps are generally set below the perforations and are designed to run in wells that are less than 4,000 ft deep and that produce less than 100 bbl/d.

These pumps help maximize production rates by keeping a well pumped off for a prolonged period without damaging the pumping system. Elimination of the electric motor and electric line to the surface increases safety and decreases lifting costs.

Efficient and environmentally friendly

• Lowers overall lifting costs by minimizing maintenance, pulling, and repair costs
• Saves time because it is easy to size and operate
• Is suitable to produce from less than 1 bbl/d up to 100 bbl/d, depending on depth

Enhanced production

• Low net positive suction head requirement of HDI allows well fluid to be drawn down to within inches of intake
• System speed can be quickly and easily changed to closely follow inflow of well
• As pump is deployed on flexible tubing, it can be spooled into and out of well quickly, reducing deferred production
