Flowback Trailers

WellFlex system for well stream flow control, pressure, temperature, and helping removing liquids from gas prior to further processing or pipeline delivery. The base unit includes a horizontal 2, 3, 4-phase separator mounted on oil field trailer from 14’ to 45+’ with operation-ready instrumentation and piping that allow quick well hookups and production. Units are for cost-saving, multi-well long-term reliable production operations. Control system can be designed for ESD (emergency shutdown system) needed on remote unmanned locations.

Enclosed units are also available for reliable operation in cold-weather climates. Cold weather units can be fitted with methanol injection, heated separator inlet or exchanger tube and or propane / air start up instrument supply for WellFlex line separator and heater combination.
