Hydraulic Jet PumpsApplications and DesignsTrico's Kobe/Oilmaster Jet Pumps can be adapted to run in awide variety of bottom hole cavities and downhole tools.The ac-tual working components of the Jet Pump—the nozzle, throatand diffuser— are assembled in a variety of configurations andmaterials to suit the production requirements and the downholeenvironment. Shown above are some of the more common JetPump applications.

The Standard Single Seal Jet Pump is shown landed in a bot-tom hole assembly designed for a hydraulic piston pump. Thisdesign permits adaptation to a wide assortment of bottom holeassemblies from many manufacturers. As a “Free Pump”, theunit may be retrieved merely by changing the flow of power fluiddown the casing annulus, unseating the pump and returning it tothe surface.The “Free Pump” feature can eliminate costly tubingpulls to retrieve the bottom hole pump.

The High Volume Jet Pump is also shown in a “Free Pump”configuration. Due to the enlarged fluid passageways of theHigh Volume Jet, a special bottom hole assembly is required.

The High Volume Jet Pump can also be run in a reverse circula-tion mode. As shown, the reverse circulation design is not a“Free Pump”, but is held in place by means of a top lock/me-chanical holddown. It is easily installed and retrieved usingconventional wireline fishing tools.

The Sliding Sleeve Jet Pump design has become popular inparticular with offshore operators. Primarily run in a reverse cir-culation mode with a top lock, the Sliding Sleeve version canalso be run on tubing if desired. Platform operators using elec-tric submersible pumps have found that the Sliding Sleeve JetPump can be run in to continue to produce a well when the ESPhas shut down. Trico’s Sliding Sleeve Jet Pumps have beenwidely accepted and are especially suited for drill stem testing,because surface pumps are already in place and well produc-tion capacity is uncertain (jet pumps can operate at less than 5percent of rated capacity without damage to the pump).

The Tubing/Packer Jet Pump can be installed in a well by wire-line methods without first pulling the tubing. As shown, this

design has wireline-set tubing packers at the top and bottom ofthe pump and straddling a gas lift mandrel. An alternate designstraddles wireline perforated tubing perforations. If a seatingnipple exists at the proper depth, it can be substituted for thebottom tubing packer.Circulation can be up or down the tubing.

The Fixed Insert and Fixed Casing Jet Pump were designedto be run in existing production tubing or casing. The Fixed In-sert is normally run inside production tubing on a macaronistring and seated metal-to-metal on the previous pump seat.Produced fluid and exhausted power fluid flow up the produc-tion tubing annulus. The Fixed Casing design—also run in onmacaroni tubing—seats on a casing packer. Production is re-turned up the casing annulus.

How It WorksPower fluid at high pressure (low velocity) is converted to a lowpressure (high velocity) jet by the nozzle. The pressure at theentrance of the throat becomes lower as the power fluid rate is

increased. When thispressure becomes lowerthan the pressure in thesuction passageway, fluidis drawn in from the wellbore. The suction fluid be-comes entrained with thehigh velocity jet and thepumping action then be-gins. After mixing in thethroat, the combinedpower fluid and suctionfluid is slowed down by the

diffuser. Because the velocity is reduced, the pressure in-creases—rising to a value sufficient to pump the fluid to thesurface.

A full range of nozzle and throat sizes are available to allowpower fluid rate and pressure to be varied to meet various re-quirements.

COILED TUBING JET PUMP

Coiled Tubing Jet PumpFrom crude oil production to de-watering gas wells, the Trico 1-1/4" Jet Pump is as rugged and dependable as it is versatile.

This slim, compact downhole pump was designed exclusively tobe run in existing 2-3/8" or 2-7/8" tubing. No expensive tubingworkovers are required, as all the necessary tools are usuallyrun in on 1-1/4" or 1-1/2" coiled tubing.The pump’s Bottom HoleAssembly can also be run in on conventional 1-1/4" jointed pipe.The pump itself is actually a “Free”Pump, and circulates hydrau-lically through the coiled or conventional tubing.

The Trico 1-1/4" Jet Pump is ideal for offshore production usewhen either the well has stopped flowing, as a replacement forgas lift installations, for de-watering gas wells or as a new liftinstallation.On a platform, where space is always at a premium,the entire hydraulic package can be custom designed to fitvirtually any space requirement. In multiple well installations,two or three wells may be able to operate from one Triplex orMultiplex pump, further eliminating space problems. In a de-watering situation, the pump can be set permanently whileusing a rental Triplex or Multiplex when necessary, thusreducing capital and operating expenses.

All Trico hydraulic “Free”Pumps are circulated in, operated, andcirculated out hydraulically, without the need for a wireline orworkover rig. This feature allows the operator to remove thepump from the well at any time for inspection or re-sizing just byredirecting the flow of fluid in a reverse pumping manner. TheTrico 1-1/4" CT Jet Pump can be circulated in and out of 1-1/4"coiled tubing without flashing removed.

Drill Stem TestThe flexibility and adaptability of the Kobe/Oilmaster Jet Pumphas proven to be an asset in doing DST on wells that are eitherdifficult to initiate flow or that will not flow. The pump provides ameans to effectively test these types of wells or zones.Probablythe simplest method is using the Sliding Sleeve Jet Pump.

The SSJ Pump has been designed to land and seal-off in a slid-ing sleeve, thereby using the sliding sleeve as a pumpreceptacle.

The use of the SSJ pump allows the use of a completely stan-dard DST tool string. Only a sliding sleeve, or ported nipple, isadded immediately above the DST tools and packer.

The SSJ pump may be locked into the sliding sleeve prior to run-ning it into the well, or it can be wirelined in after the DST toolsare run in and landed. The use of an annulus-controlled safetyvalve immediately below the sliding sleeve provides additionalwell control and allows other useful operations to be performed.

Features/AdvantagesThe use of complicated coiled tubing methods for well testingare a thing of the past, replaced by Trico’s effective and efficientSliding Sleeve Jet Pump.

When used for Drill Stem Testing, the SSJ pump:

· Provides lower cost drill stem tests—no special equipmentto hook up on surface; reduced rig time and run time (nocoiled tubing or ESP cable).

· Allows completely standard DST surface and subsurfacehook-ups.

· Provides maximum power fluid passage.· Provides large volume production capability up “full open”

drill string.· Allows SSJ Pump to be installed and retrieved by standard

wireline procedures.· Allows well to be “kicked-off” safely.· Provides jet pump “rangeability” to test over wide range of

production rates.

Using the SSJ to Kick-Off a WellIt may become evident after obtaining well test data using theSSJ Pump that the well will flow if it can be “kicked-off”. With anSSJ Pump in the sliding sleeve and an annulus-controlledsafety valve immediately below the sliding sleeve, this can beeasily done.

The following steps will accomplish this:

1. Pump water down the casing annulus at surface pressurebelow the pressure required to open safety valve.

2. Continue pumping until all production fluids are circulatedout of drill string; now annulus and tubing gradients arethe same.

3. Retrieve SSJ Pump with wireline tools, then run in wire-line tool used to close sliding sleeve & hang-off over slid-ing sleeve.

4. Pump diesel or other light fluid down the drill string andspot just above the sliding sleeve.

5. Close the sliding sleeve with wireline tool and retrievetools.

6. Rig wellhead to flow.

7. Pressure-up annulus and hold pressure to open annulus-controlled safety valve allowing well to flow.

8. If well does not flow, open sliding sleeve, run SSJ Pumpand operate with sufficient pressure to also open safetyvalve.

SINGLE VESSEL UNIDRAULIC ®

The TRICO UNIDRAULIC® is a complete, self-contained hydraulicpower fluid system that is typically mounted at the wellsite. Well flu-ids are separated by the TRICO UNIDRAULIC into power fluid andproduced (flowline) fluid. The produced fluid is directed to the pro-duction facility and the power fluid is cleaned (by cyclone desand-ers) for use in operating the downhole piston pump or jet pump.

The TRICO UNIDRAULIC permits an individual well to be producedhydraulically and at a cost competitive with other methods of artifi-cial lift.

Other advantages of the TRICO UNIDRAULIC Pumping System in-clude:

· Compact and easily installed unit.· Economical and flexible.· Operates with Kobe/Oilmaster downhole piston or jet pumps· No pre-planning of a central facility.· No changes required in an existing tank battery.· No need for increased central treating facilities.· A quick, simple, economical way to produce a single well hy-

draulically.· Fully portable single or two-skid-mounted design can be easily

installed or moved as required by lease production.

Features to look for in theTRICO UNIDRAULICReservoir VesselThe vessel provides a source of power fluid to operate the system.Vessel plumbing permits selection of produced oil or produced wa-ter

as power fluid. The wells’ produced fluid volume is discharged di-rectly to the flowline through a simple gravity dump level control sys-tem. Standard vessel sizes are 60" x 10’ and 60" x 20’. Other sizesare available on request.

Cyclone CleanersThese condition the power fluid by removing solids and contami-nants to provide clean power fluid.

By choosing the number of cyclones to provide maximum powerfluid conditioning, the system has an adequate clean power fluidsupply. The circulating pump assures that the power fluid passesthrough the cyclones before reaching the Triplex or Multiplex Pump.Power conditioning is controlled and constant—not dependent onthe variable flow rates from the well.

Circulating PumpProvides optimum circulating rate through the cyclone cleaners.

Triplex or Multiplex Power PumpSized to provide high pressure power fluid for system operation. Afield-proven, dependable power pump for continuous-duty opera-tion.For maximum flexibility, the Triplex or Multiplex Pump is offeredin a number of sizes from 25 H.P. to 630 H.P.

Single or Two-Skid ModelsSingle-skid models are available with electric motors as the primemover for the Triplex or Multiplex Pump. The two-skid units can beequipped with electric, gas or diesel prime movers. With the two-skid model, the reservoir vessel and the Triplex or Multiplex Pumpare mounted on their own separate skid base for maximum safetyand installation efficiency. The 60" x 20’ vessel is only available as atwo-skid package. If necessary, both skids can be housed for foulweather operation.

The Crossover Assembly, or “Y” tool, allows downhole surveys to betaken with wireline equipment while electric submersible pumpingequipment is in place and operating in the well. The “Y” tool, calledso because of its unique shape, provides a piping arrangementwhich offsets the pump, allowing survey tools to go straight throughto the bottom of the well. Surveys are recorded without disturbingthe pumps' original function, even in directional wells drilled up to 75degrees. The “Y” tool also provides a method of blanking off whilethe well is in a normal producing mode or while a survey is in pro-cess.

The “Y” tool is useful for production operators in a number of moni-toring applications, including the location of excessive water or gasentry from undesirable subzone contributors, tracking water andgas cap movement within a production reservoir, and monitoringpressures, temperatures and fluid levels.

The Crossover Assembly has four major components:

Crossover — The original crossover assembly is designed to run in8-5/8 inch or larger casing on 2-7/8 inch tubing. Smaller crossoverassemblies are available for operation on 7 inch-26 lb.casing and 2-3/8 inch tubing. A 3 inch, 9-5/8 inch unit has also been developed toaccommodate 5-1/2 inch pumps and motors and the running of 1-11/16 inch survey tools.

The crossover body is streamlined using non-upset tubing and hasno internal shoulders where survey tools can hang up. The straightportion is made of heavy seamless tubing to prevent fluid cutout.Each unit, after complete assembly, is hydraulically tested for leaksto above 3,000 psi. The tool incorporates a seating nipple thathouses a stainless steel seating ring and is capable of accommo-dating different types of plugs.

Crossover Assembly

Blanking Plug — The original blanking plugs are solid and madewith API top-lock pump parts.A flow-through type blanking plug, ad-vantageous in many cases, is also available, again utilizing API top-lock rod pump components. Each plug assembly has a fishing necklooking up, and when seated in the seating ring, the neck protrudespast the fluid port of the crossover assembly, allowing producedfluid to keep the neck washed free of sand. The function of this plugis to blank off the instrument port section while the well is pumpingnormally.

Running Plug — The running plug is similar to the blanking plug,except that a wire or recording line can be run through it. The linesare normally 3/16 inches or 5/16 inches in size. A brass bushing inthe tool functions as a stuffing box or packoff with minimum fluid by-pass. To prevent the loss of survey tools should wireline separationoccur during retrieving operations, an overshot is provided on thebottom of the running plug containing slips sized to catch the surveytool fishing neck. The survey tool and running plug can then be re-moved from their seated position by alternate means and the wellreturned to production after returning the blanking plug to its seatedposition.

Instrument Tube — The instrument tube connects to the crossoverassembly providing a passageway for survey tools alongside thesubmersible pump installation and into the producing zones. Thereare no internal shoulders present throughout the assembly. Thetube is held straight and parallel to the installation by simply clamp-ing it to the submersible unit with steel banding clamps. The bottomof the pump instrument tube is cut at an angle and hangs at the bot-tom of the pump installation. Instrument tubes may be joined to-gether to obtain the correct overall length.
