1. Power fluid is pumped through a nozzle

2. Power fluid exits the nozzle at high velocity whichcreates a drop in pressure

3. The low pressure area created by the stream of fluidexiting the nozzle draws in formation fluid

4. The power fluid is combined with the produced fluid inthe mixing tube

5. The power fluid and produced fluid are slowed asvelocity is converted back to pressure in the diffuser

6. Power fluid and produced fluid exit the jet pumphousing and travel up the annulus

1. Jet Pump Housing Run in with coil tubing or work over rig.Coated with Boron Carbide. Very corrosion and erosion resistant.

2. Standing Valve Ball and seat located in the bottom of thehousing. Keeps tubing string full when pump is not running.Allows carrier to be hydraulically retrieved.

3. Carrier Houses the nozzle and mixing tube. Small in size.Dropped down the tubing from the surface and pumped into placewhen well is put into production. Can be hydraulically retrieved orfished with wire line. Made of 17-4 Stainless steel.

3. Nozzle and Mixing Tube Primary components of jet pump.Various combinations of sizes depending on desired productionand other variables of the well. Extremely erosion resistant. Made

of Tungsten Carbide.

100% Made in America

Jet PumpHousing

Packer

Traditionally in oil wells the jet pump wouldbe set above a packer

Power fluid is pumped down the tubingstring

Power fluid and produced fluid returns upthe annulus

Capable of producing over 10,000 bbl/day

A reverse flow model can be used to removefrac fluid in order to keep the frac sand fromgathering on top of the packer

The jet pump has excellent gas handlingcapabilities

However in most gas well dewatering applicationswhere more gas is produced than liquid (very high

GLR) the jet pump becomes inefficient

In these cases it is necessary to prevent the gas

from entering the pump

This is accomplished by running concentric strings


7/25

1. 2-3/8 or larger production tubing is run with aseating nipple and a perforated sub set below the perfs

2. The jet pump housing (1.6 OD) is configured with a

hold down seal assembly and a strainer nipple on thebottom

3. The jet pump housing is run on 1 or larger integral

joint or coil tubing and stabbed into the seating nipple

4. If no rat hole is available a down-hole gas liquidseparator or gas anchor can be used.

5. Pump housing must be set below the producing fluidlevel

By collecting your well data and inputting it into thesoftware we are able to determine:

1. How much horse power will be required to reach your desiredproduction rate

2. What size surface pump is needed

3. The most efficient combination of nozzle and mixing tube to

run

4. Once the jet pump has been put into service we can use theprogram and see what the pumping bottom hole pressure is or

calculate a fluid level

5. After production has stabilized we re-evaluate the data to makesure that we are running the most efficient nozzle and mixing

tube combination

Hydraulic Jet Pump Analysis


11/25

No moving parts down-hole

Can be run in crooked, deviated, or horizontal

wells

Ability to produce sands and solids

Corrosion and erosion resistant

Ability to move large volumes of fluid (over 1000bbl/day with smaller slim-hole model)

Will not gas lock


12/25

Power fluid can be treated with scale and corrosioninhibitors

Ease of serviceability (can be hydraulically retrievedby reversing flow)

Ease of optimization with use of software

Production rate can be adjusted by adjusting

down-hole pressure and rate

Continuous pull on formation designed to run 24/7


13/25

The jet pump requires a surface pump and a cleansource of power fluid. Either produced water or oilcan be used as power fluid.

In most applications a pressurized vessel is used aspower fluid source. Fluid is pulled out of the vesseland pumped down the tubing. Power fluid andproduced fluid return from the well and back to thevessel. The excess fluid overflows out the top and issent down the sales line.

Surface pumps can range from 15 HP to 450 HPdepending on the number of wells pumped, desiredproduction rate, depth of well, and pumping bottomhole pressure.

Surface pumps can be electric or gas driven.

Using a size A:1 nozzle and mixing tube combination 2380 psi and 447 bpd(20 HP) is required to produce 80 bpd when pump inlet pressure is 150 psi.

Producing Fluid Level Calculation:Hydrostatic Head Above Pump = 150 psi (pump inlet) 90 psi (casing) = 60 psiFluid Level Above Pump = 60 psi (head) / 0.466 psi/ft (gradient) = 129 ft.Producing Fluid Level = 5050 ft. 129 ft. = 4921 ft.
