Less expensive than our higher capacity launchers, the Model 1 and Model 2 automatic Soap Stick Launchers are specifically designed and engineered for locations flowing with minimal pressure or higher pressures (2000 WP – 5000 WP optional).

The Midnight Launcher increases gas well production through automatic application of soap sticks (surfactants) into the well bore. With older, outdated methods, soap sticks are commonly dropped by twin-valve manual launchers requiring the operator to make multiple visits to a well which increases OPEX.

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


Pro-Seal Lift Systems’ Model 1 and Model 2 Midnight Soap Stick Launchers also provide the following important features and benefits:

  • Both Models are completely Solar Powered.

  • Affordable for low pressure gathering systems.

  • Ideal solution for high pressure wellheads.

  • 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 basic operational functions of the Midnight Soap Stick Launchers are:

  • Telemetry: A soap stick can be dropped from an RTU command while the operation of the flow-control valve is initiated by the RTU.

  • Deactivation: The Controller and the Midnight Soap Stick Launcher can be disabled or deactivated indefinitely without a loss of time settings previously programmed. Use this deactivation feature when the field is shut-in for several days.
