The use of the plunger lift method of artificial lift in oil and gaswells is increasing at a rapid rate. Several reasons for this increasestem from general developments in the industry.

Plunger lift excels at producing high GLR oil wells and removingliquid accumulations from gas wells. As reservoirs deplete and flowing rates decline, the gas phase becomes less efficient at liftingthe liquid phase to the surface. Allowed to continue, the flowing gradient will become heavier until the well loads up with liquid and stops flowing.

One of the most efficient methods of producing liquid involves theuse of the cycle controlled plunger. The plunger makes continuouscontact with the inside wall of the tubing string, thereby forming an effective seal between the lifting gas and the lifted liquid.Operation of the system is as follows.

The motor valve on the flowline is closed and the plunger is restingat the bottom of the tubing. Gas Pressure is building in both the tubing and the casing-tubing annulus.

By opening the motor valve at the surface, gas is produced to a lower pressure separator or gathering system allowing a reductionin tubing pressure. Gas accumulated in the annulus continues toexpand into the tubing behind the rising plunger until it is forced tothe surface. This pressure reduction is the energy source to movethe plunger and liquid slug from the bottom of the tubing to the surface. Storage gas in the casing-tubing annulus and/or formationgas will be the drive mechanism for plunger movement.

F1 SET TIMES F2 DATA HISTORY F3 SYSTEM INFORMATION


Upon reaching the surface and removing the liquid slug from the tubing, the well controller can either shut-in on plunger arrival orcontinue to produce gas for a predicted interval.

When the motor valve closes on the surface flowline, the plunger fallsback to the bottom of the tubing string due to gravity. The plunger isnot a perfect sealing device and will fall through the fluid that hasaccumulated in the bottom of the tubing coinciding with the low pressure experienced during the flow cycle. Once enough time haselapsed for the plunger to reach the bottom, the well may be ready tocycle again. Depending on the reservoir, additional pressure build upmay be required before another cycle can be made.

In gas wells, smaller tubing, a compressor, or plunger lift isinstalled to maintain flowing status. Neither the smaller tubing nor acompressor is a permanent solution. They increase the gas velocityinitially so that the liquid will be removed from the tubing, however,at some time in the future the gas rate will again fall to an inadequatelevel and liquid will not be removed from the well creating a loadedor semi-loaded condition. Plunger lift provides a permanent solutionat a lower price than any other method.

Once the well stops flowing (if the GLR is high enough), or earlierin an effort to lighten the flowing gradient and increase reservoirdraw down pressure, plunger lift can be installed. Plunger lift can beexpected to produce the well to depletion. There are no absolute maximum producing rates for plunger lift, as there are none for flowing wells. The limiting producing rate in both cases is as muchdependent upon the inflow performance of the well as it is upon its outflow performance.

The LIQUILIFT III Controller is an electronic time based well controller. It is a combination of previous designs, allowing the operator to select multiple solutions for well operations. TheCustomer has the ability to change Control Modes from SingleValve, Dual Valve or Intermittent Operation within the same control unit. A key feature with this controller is the MenuStructure. This type of operating system allows increased ease of:

setting operational parameters retrieving data and system evaluation

Hot Key features improve maneuvering from Data Groups andData Entry. Other exciting enhancements have been added to givethe Customer quick access to well and system performance.

The LIQUILIFT III Controller operates on time and/or pressureinputs. It does not make any adjustments for plunger speed variationbut does have the capability to add off time (Recovery Mode) for a plunger not surfacing during the On Cycle.

The Controller offers you 3 mode selections for well operations.

To operate with a single motor valve on the flowline select thePLUNGER MODE.

To operate with dual motor valves, perhaps one on the flowline andone redirecting flow to the stock tank, select TANK MODE. These 2 applications can operate in SYNChronized MODE and have RECOVERY MODE available for NO ARRIVALS.

T H E O R Y O F O P E R A T I O N

To operate with a single motor valve on the flowline and not make anyadjustments to the operation select INTER MODE. This mode has a reduced number of operating parameters (TBG ON, TBG OFF and H-L DELAY) and is available strictly for intermittent operation.

This unit can be utilized in a host of different scenarios but is primarily used with Plunger Lift. The controller is manufactured with a single latching solenoid valve for supplying source gas to adiaphragm operated motor valve. If the operator selects the dualvalve option (TANK MODE), an external latch valve will be suppliedto actuate the second motor valve.

Many features can be used to make the controller function asrequired. They are briefly described below:

Pressure switch gauges can be used as an override to turn the controller on or off.

The controller can be operated from differential pressure if two switch gauges are wired together.

The MSO switch will permit the controller to detect plungerarrival and Afterflow if time is programmed. If dual valve oper-ation is used the second motor valve will close once theplunger arrival is detected.

The controller will keep track of the last 15 plunger arrivaltimes and calculate the average run time automatically.

Selecting Recovery Mode allows additional Off Time if theplunger fails to surface during the On Time .

Selecting Sync Mode allows the controller to operate underconstant time cycles.

The Intermitter Mode can be selected to simply operate a single motor valve with minimal settings.

Independent motor valve settings can be made using the TANK MODE.

The controller operates in hours, minutes and seconds.

High sales line pressure can signal the controller to shut-inand not attempt to cycle.

These are just a few of the selections and combinations that can be accomplished with this versatile controller.

The LIQUILIFT III Controller can be mounted directly to amotor valve by using the supplied installation kit. See Figure 1, Page 21.

Kit contents are listed below:

2 - 3/8-24 x 5/8 SS Bolt1 - 0-30 psi SS Gage - 1/8 NPT Center Mount1 - Combination Flat/Angle Bracket (Black Anodized)1 - Screwdriver

Place the black combination bracket on the bottom of the enclosurewith the short angle section next to the back of the valves. Insert (2)3/8-24 SS bolts. Using a 9/16 wrench, tighten securely.

Remove 2 bolts and nuts from the motor valve diaphragm bonnet.

Attach the enclosure and combination bracket to the motor valvebonnet using the same bolts and nuts.

Install the 0-30 psi 1/8 NPT center mount gage to the front port forthe valve manifold using a 7/16 open-end wrench.

Gas is supplied to the valve manifold from either the left or right side. The Unit is shipped with a 1/4 NPT plug in the right side of the single valve manifold.

Using a 1/4 NPT x 1/4 Tube brass straight gas can be supplied froma 30-psi (max) gas source, typically from the drip pot and regulator.

If an in-line gas filter is used, it is installed into the valve manifoldprior to installing the brass straight.

The Sales Valve output pressure port is located on the bottom. Itrequires a 1/4 NPT x 1/4 tube, straight or 90, to make connection to the motor valve. See Figure 2, Page 22.

Installation can also be made to 2 line pipe using the combinationbracket. This requires rotating the combination bracket 180o. Thisalso requires a 2 u-bolt (not supplied) to attach to the vertical 2 pipe.

If the TANK MODE option is selected, an external latch valve will be utilized to actuate the secondary motor valve. The externallatch valve functions exactly like the valve manifold built in theController, but is contained inside a separate metal housing detachedfrom the controller.

The controller solenoid valve, D-Cell battery pack, and/or 6 -Voltgel battery (Optional) are wired from the factory using specialspring-loaded connectors to protect against electrical shorts and accidental mishaps. The electronic module is located on the back ofthe faceplate. Connector plugs for the auxiliary devices are providedunpopulated and are snapped into the sockets on the circuit board.

Typically, the only connections required may be the MSO switchand solar panel wire if applicable. A ground lug has been provided to protect the electronics and should be utilized with a copperground rod to enhance the controllers immunity to transients.

Plug wiring connectors are provided on the PCB module. Wiringto the plug connector is accomplished by inserting a small screwdriver (provided) into the smaller slot of the two openings located on the end of the plug. Once the screwdriver isinserted in the slot, rotate 90o to secure the screwdriver in place. This action will open the spring connector and allow the wire to be completely engaged to the plug. Removing the screwdriver will clamp the wire in place. See figure 3, Page 23.

Provisions have been made to bring the solar panel wire into the left side of the enclosure through a watertight connector.

NOTE: The solar panel orientation should be toward the south orequator for optimum sunlight.

One wire is marked with a white stripe and should be connected to the positive side of the 2-pin solar plug connector. The other wire is connected to the negative. The wires are connected as mentioned previously.

Now that the wires are properly attached to the connector, the plug can be inserted into the socket marked SOLAR located on the module cover plate. See Figure 4, Page 24.

This controller contains electronic components, which compensatefor ambient temperature conditions. The Liquid Crystal Display(LCD) will sometimes appear to be too dark or too light to read.Make sure that you are at the MAIN MENU by pressing theMENU/ESC KEY. Then, by repeatedly pressing the LEFT orRIGHT ARROW KEYS, the display contrast can be adjusted to your preference. The controller will remember this setting even after the display goes to sleep.

The following is a description of all operating parameters in the F1, F2 and F3 MENU GROUPS. All numbers shown in BLUErelate to HOT KEY numbers. Also note that all time settings are in HRS: MIN: SEC format.

TBG ON: TUBING ON TIME is the total amount of time you wantthe well to stay on for the plunger to arrive at the surface. A goodplace to start in establishing an ON TIME is by dividing the depth of the tubing by 400.

TBG OFF: TUBING OFF TIME is the total amount of time you want the well to stay off or shut in.

AFTFLW: AFTERFLOW TIME is the time the well will be allowed to flow after the plunger has surfaced.

H-L DELAY: HIGH LINE DELAY TIME is a delay feature for use with a line pressure switch gauge. This delay time allows the normal cycle to make and break contact with this switch during the early part of the ON CYCLE and continue to operate. Ifthe line pressure remains high and the contact is not broken beforethe delay times out, the well will shut in. This will automatically startthe OFF TIME.

SYNC MODE: This is a special mode used when synchronized timing is required to reduce interference with other wells in thesame gathering system. SYNC MODE enables constant cycles to be programmed. To enable SYNC MODE, select YES from the display.This will allow the FLOW TIME to be entered on the next line (#24).If the Tank Mode is selected, the SYNC MODE may be used to operate the two valves independently (see SCENARIO #2).

FLOW TIME: This is the total time that the sales valve can be on. It is generally equal to the ON TIME + AFTERFLOW TIME. Thisfunction is not available unless the SYNC MODE is set to YES. The following is an example of time settings when using SYNCMODE and FLOW TIME.

For example:ON TIME: 30 minutesAFTERFLOW TIME: 15 minutesFLOW TIME: 45 minutesOFF TIME: 1 hour

The total cycle time is OFF TIME + FLOW TIME = 1 hour45 minutes. This allows afterflow.

RECOVERY MODE: RECOVERY MODE is a feature, whichenables an alternate OFF TIME to be entered if the plunger does not arrive during the ON TIME. The RECOVERY TIME is entered on the next line (#26). If the plunger still does not arrive after the ALTERNATE OFF TIME is used it remains the same for the next cycle. After the plunger arrival is made during the ON CYCLE, the OFF TIME reverts back to the original setting.

RCVRY TIME: RECOVERY TIME is an alternate OFF TIME used when the plunger does not arrive during the TUBING ONTIME. Be careful with this time when using SYNC MODE. (See Scenario #1 at end of manual).

TANK DELAY: TANK DELAY TIME is the delay time before the second motor valve is allowed to turn on or open. TANK DELAY TIME always starts timing at the beginning of the TBG ONTIME. It is generally used to sell high-pressure gas down the gassales line before having to open to a lower pressure to surface theplunger. If the plunger arrives before the delay time expires the TANK ON TIME is bypassed. This option is only available if theTANK MODE is selected.

TANK ON: TANK ON TIME is the total time the tank valve will be open (provided that the plunger has not arrived). The TANK ON TIME starts at the end of the TANK DELAY TIME. If the tank valve opens and the plunger arrives during the on time,the tank valve will close and the Tubing valve will either start the AFTERFLOW cycle or shut-in (depending on the program status). This option is only available if the TANK MODE is selected.

TANK OFF: TANK OFF time is the total time that the TANKVALVE is closed during the cycle. The TANK VALVE can be independently programmed from the TUBING VALVE. The TANKOFF time is only available when in TANK MODE and SYNC MODE is set to YES .

TBG CYCLES: TOTAL TUBING CYCLES are the total number of tubing cycles since the totals were last cleared.

PLUNGER CTS: PLUNGER COUNTS are the total number ofplunger arrivals since the totals were last cleared.

PLUNGER RUN TIMES: PLUNGER RUN TIMES are the actual run times (last 15) and the average of these 15 run times. Thisline requires you to PRESS the ENTER KEY to retrieve the first 4lines, then use the down arrow to review the rest of the individualtimes. These values are retained when you clear the totals.

TTL TBG ON: TOTAL TUBING ON TIME is the cumulative ON TIME including AFTERFLOW TIME that the TUBING VALVEhas been open since the totals were last cleared.

TTL TBG OFF: TOTAL TUBING OFF TIME is the cumulative OFF TIME that the TUBING VALVE has been closed since the totalswere last cleared.

The combination of SYNC MODE and RECOVERY MODE allows for a variety of production scenarios. A few examples follow:

SCENARIO #1: The below scenario will allow the controller to stay in SYNC with other wells and switch to a longer Sales Off Time (Recovery Time) for a no arrival.

ON TIME: 30 minutesAFTERFLOW TIME: 15 minutesSYNC MODE: YESFLOW TIME: 45 minutes (set by the operator for On Time + Afterflow)OFF TIME: 1 hourRECOVERY MODE: YESRECOVERY TIME: 2 hours 45 minutes (OFF TIME +FLOW TIME + OFF TIME)

NOTE: The ON key must be pressed to insure that the controllerstarts timing properly when SYNC MODE is selected.

SCENARIO #2: The below scenario will allow two Sales Cycles for every one Tank Cycle. Notice that the Tank Cycle is twice that ofthe Sales Cycle.

ON TIME: 30 minutesAFTERFLOW TIME: 15 minutesSYNC MODE: YESFLOW TIME: 45 minutes (set by the operator for On Time + Afterflow)OFF TIME: 1 hour


P R O D U C T I O N O P E R A T I N G S C E N A R I O S



Sales Cycle = 1 hour 45 minutes (Flow Time + Off Time)

TANK DELAY TIME: 30 minutesTANK ON TIME: 15 minutesTANK OFF TIME: 2 hour 45 minutes Tank Cycle = 3 hours 30 minutes (Tank Delay + Tank On +Tank Off)

IMPORTANT: It is up to the operator to select cycle times that areeven multiples of each other. (i.e. 2 sales cycles per 1 tank cycle).The ON key must be pressed to insure that the controller starts timing properly when SYNC MODE is selected.

SCENARIO #3: The below scenario will allow one Tank Cycle forevery Sales Cycle and keep the well in sync with other wells in thegathering system. Notice that the Sales Cycle equals the Tank Cycle.

ON TIME: 30 minutesAFTERFLOW TIME: 15 minutesSYNC MODE: YESFLOW TIME: 45 minutes (set by the operator for On Time+ Afterflow)OFF TIME: 1 hourSales Cycle = 1 hour 45 minutes (Flow Time + Off Time)

TANK DELAY TIME: 20 minutesTANK ON TIME: 10 minutesTANK OFF TIME: 1 hour 15 minutesTank Cycle = 1 hour 45 minutes (Tank Delay + Tank On +Tank Off)

19


SCENARIO #4: The below scenario will allow one Tank Cycle for every Sales Cycle. Note that SYNC MODE is not enabled.

ON TIME: 30 minutesAFTERFLOW TIME: 15 minutesSYNC MODE: NOOFF TIME: 1 hour

TANK DELAY TIME: 20 minutesTANK ON TIME: 10 minutes

In this case the Tank Off time is not available because SYNC modeis not enabled. The TANK DELAY and subsequent tank cycle willautomatically start when the Sales OFF time expires. Concurrently,the Sales Valve will open and start the SALES ON timer.

The new Liquilift III electronic controller is a state of the art product designed to ease of operation, and for maximum reliability.
