Model 9E and Model 18E - Soap Stick Launchers

Solar Powered Soap Stick Launcher Eliminates the Need for Supply Gas!

The Pro-Seal automatic Soap Stick Launcher increases gas well production through automatic application of soap sticks (surfactants) into the wellbore. Without an automatic Launcher, soap sticks are manually dropped by a two-valve launcher requiring the operator to make multiple visits to the well - which increases OPEX.

By utilizing the programmable automatic Soap Stick Launcher, surfactants can be dropped automatically over an extended period of time. Introducing soap sticks at the optimum point in the flow regime can dramatically improve the performance of a well’s production plus reduce the man hours required to service the well.

Model 9E – Solar Powered

The Model 9E Soap Stick Launcher is a low-profile unit measuring only 32” tall. With a capacity of nine 1-1/4” diameter soap sticks, the Model 9E can be programmed to drop 1 to 3 soap sticks per cycle.

Model 18E – Solar Powered

When a well requires additional surfactant to maintain maximum production, the Model 18E is the unit of choice. Measuring only 15” taller than the 9E, the Model 18E offers a capacity of eighteen 1-1/4” diameter sticks and is programmable to drop 2, 4 or 6 sticks at each cycle.

Pro-Seal Lift Systems’ Model 9E and Model 18E automatic Soap Stick Launchers provide the following important features:

  • Actuation: Both Models are Solar Battery Powered – no supply gas required.

  • Max. Flow: The automatic Soap Stick Launcher can operate without a shut-in period by dropping a soap stick on the fly allowing the well to flow continuously if the flow rate is less than 250 MCFD in 2-3/8” tubing (or 500 MCFD in 2-7/8” tubing).

  • Flow Rate - Gas: The Model E can be programmed to send a low amperage signal to open/close an electric valve in the flow line such as the ABV-PM. This function is required when the well produces gas above the allowable wing-block rate.

  • Flow Rate - Liquids: The Model E can close / open a 12v electric valve in the flow line when the well produces an excess of water above the allowable wing-block rate. Combining stop-cocking with a soap stick is the solution for de-watering -- up to 200 barrels of liquid per day from 2-3/8” tubing.

  • 12v Flow Control Valve: An ABV-PM controlled by the Model E Launcher is ideal for shutting-in weaker wells that benefit from a pressure/volume building period of 1 or 2 hours. Once the ABV-PM reopens, its large flow area causes no undue back-pressure – a real advantage for low pressure systems.

  • Tank Option: For a weaker well, the Model E Soap Stick Launcher can drop a stick against the flow, wait 30-45 minutes, then re-direct the gas flow to the Tank. This reduction in back pressure will allow the fluid slug to reach the surface.

  • Casing Flow: The Model E can alternately flow from the casing or the tubing for the purpose of de-watering the well bore of high flow-rate locations. Download the Manual or contact us to discuss this feature.

  • Controller: The Solar Powered microprocessor features a continuous digital readout indicating the quantity of soap sticks in the Launcher as well as the time remaining until the next scheduled drop. The Controller can coordinate the flow from 1 or 2 electric actuated flow control valves.

  • Telemetry: Soap sticks can be dropped from an RTU command and the operation of the flow-control valve can be initiated by the RTU or the Launcher Controller – your choice.

  • Deactivation: The Controller of the automatic Soap Stick Launcher can be disabled or deactivated indefinitely without loss of the time settings previously programmed.

  • Launch Indicators: A rise in casing pressure indicates fluid loading in the tubing. Adding a transducer or Murphy Switch on the casing side can initiate a stick-drop into the tubing when the casing pressure reaches a pre-set value. Under these conditions, the launch is based on pressure, not time.

  • Connections: All Models available for 2″ NPT, 2-3/8″, or 2-7/8″ wellheads. We also offer low-profile adapters for 2″ NPT through 4-1/2″-8 rnd.

The Model E and the Model P Launchers use the same Processor and offer the same general features. The distinctions of using the Model E are: 

  • the benefit of using solar power when supply gas pressure is not sufficient;

  • the benefit of using the ABV-PM (actuated ball valve) when the use of a pneumatic valve causes undue flow restrictions in the sales line;

  • the reduction in gas emissions by using solar battery power on location;

  • the avoidance of using supply gas when low temperatures can cause freezing issues in the control system;

Soap Stick Launcher Basic Operational Functions:

  • Telemetry: Soap sticks can be dropped from an RTU command and the operation of the flow-control valve can be initiated by the RTU or the Launcher Controller – your choice.

  • Motor Valve: For this function please refer to our Model 9P or 18P.

  • Max. Flow: The automatic Soap Stick Launcher can operate without a shut-in period by dropping a soap stick on the fly allowing the well to flow continuously.

  • Casing Pressure: A rise in casing pressure indicates fluid loading in the tubing. A transducer or Murphy Switch on the casing side can initiate a stick-drop into the tubing when the casing pressure reaches a pre-set value.

  • Controller: The Solar Powered microprocessor features a continuous digital readout indicating the quantity of soap sticks in the Launcher as well as the time remaining until the next scheduled drop.

  • Deactivation: The Controller of the automatic Soap Stick Launcher can be disabled or deactivated indefinitely with a simple button push without loss of the time settings previously programmed. This is a feature particularly helpful in fields that share a compressor with a nearby well on Plunger Lift.
