Product Families
Horizontal Three-Phase Separators
Cylindrical vessels mounted horizontally that maximize the gas-liquid interface area and provide long, stable oil-water settling zones. They are the preferred configuration for high liquid loads and for streams requiring effective oil-water separation.
Vertical Three-Phase Separators
Upright cylindrical vessels with a smaller plot footprint, well suited to high gas-to-liquid ratios and to streams carrying significant sand or solids that settle to a conical or flat bottom for removal.
Two-Barrel (Double-Barrel) Separators
A configuration using an upper barrel for gas separation and a lower barrel for liquid retention, increasing effective liquid residence time without enlarging the gas section. Used where high liquid volumes coincide with high gas flow.
Bucket-and-Weir Separators
Horizontal separators that maintain the oil-water interface using an oil bucket and a water weir rather than an interface-level controller, providing reliable phase splitting where interface emulsions or unsteady levels complicate level sensing.
Wellsite (Wellhead) Production Separators
Skid-mounted, often portable three-phase units installed at individual wells or pads to separate oil, gas, and water at field pressures ahead of gathering. Frequently combined with test capability for individual well measurement.
Test Separators
Separators dedicated to measuring the oil, gas, and water rates of an individual well during a test period, equipped with metering on each outlet to allocate production and characterize well performance.
Free-Water Knockout (FWKO) Vessels
Three-phase vessels optimized to remove the bulk of free water upstream of treating, leaving oil with reduced water content and a separate water stream; they prioritize water removal over fine gas separation.
