Hydraulic pumping produces oil wells by the transfer of energy through fluid topower the subsurface pump. The subsurface pump uses the power fluid pressureand volume to lift well fluids to the surface. Power fluid can be well fluids, oil orwater. In most cases, well fluids are cleaned by a power fluid conditioning systemand stored for injection back in the well by a surface multiplex pump. Jet and pis-ton subsurface pump designs provide a wide range of application.

The jet pump provides high volume production rate capacity with no movingparts, but requires higher reservoir energy while the piston pump will produce thewell to very low reservoir pressure.

Together, OHI jet and piston pumps offer a wide range of applications. However,hydraulic pumping is generally considered when the toughest problems develop.OHI hydraulic pumping systems produce economically and reliably from deep wellswith solids, sand, paraffin, heavy oil, water, gas or corrosive fluids. OHI pumps arealso easily installed in crooked wells, deviated wells, offshore platforms, remote jun-gle areas, urban areas, and environmentally conscious areas. Special pump designsare available for such completions as sliding sleeves, gas lift mandrels, coil tubing,DST, well cleaning and testing.

OHI pumps are economical, rugged, and most models are field repairable.However, the greatest advantage of hydraulic pumping is that the subsurface pumpcan be retrieved by reversing fluid flow, eliminating the time and cost for wireline orworkover rigs.

Since 1991


Oilwell Hydraulics, Inc. offers a complete line of surface power and fluid conditioning systems,from the centralized multiple well automated pumping station to the unitized transportable test pack-age. Systems are engineered to efficiently separate well fluids and remove sand, solids, and gas foruse as power fluid. Clean power fluid reduces wear, repair frequency, and operating cost.

OHI systems provide reliable, rugged and economical solutions to oil well production, competitivewith all other lift methods.

Surface Pump: Proven high pressure positive displacement plunger pumps available in many horse-power ranges that meet your needs. Components and accessories are selected for reliable operationin high pressure continuous hydraulic pumping. Installation must consider pump NPSH requirements.See pump specifications section for details.

Central Power Fluid Treatment: Central systems provide power fluid tank designs considering reten-tion time and features to maximize separation of gas and minimize turbulence to remove solids andsand. Existing process equipment provides added treatment. Cyclone solids separators add powerfluid conditioning efficiency.

Valves, Controls, & Piping: Accessories are supplied to insure 5000-psi pressure rating, full boreand corrosion resistant materials. Discharge piping will include long radius bends to avoid excessivevibration. Relief valve and drain outlets are piped to environmentally secured areas.

Oilwell Hydraulics, Inc. jet pumps offer the most reliable, economical and well-designed equipment topump a well. OHI offers a wide selection of sizes and advanced materials for the petroleum and mining industries.

Jet Pump Operation:High-pressure power fluid provides a high veloci-ty jet stream at the nozzle that intermixes withwell fluids through a mixing tube called “throat”.The mixture passes through a diffuser whereincreasing flow area reduces flow velocity andincreases pressure sufficient to lift the combinedfluids to surface.

Production rate is determined by the energy pro-vided by the nozzle pressure through the arearatio between the throat and nozzle combina-tion, along with reservoir energy at the pump. Awide range of production rate and lift capacity isavailable through the combination of differentthroats and nozzles. Performance curves assistin optimization.
