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 a well. With older, outdated methods, soap sticks are commonly dropped by twin-valve manual launchers requiring the operators to make multiple visits to the well which increases OPEX.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 servicing the well.

Model 9E – Solar Powered

Designed for convenience and safety, the Model 9E Soap Stick Launcher is our low profile until measuring only 32″ tall – the shortest Launcher on the market! With a capacity of nine 1-1/4″ diameter soap sticks the Model 9E can be programmed to drop 1 to 4 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 its little brother, the Model 18E offers a capacity of eighteen 1-1/4″ diameter sticks and is programmable to drop 2, 4, 6, or 8 sticks in one cycle.

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

  • Both Models are completely Solar Powered – no supply gas required.

  • 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. 


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.
