Surface Well Testing

Three-Phase Well Test SeparatorWeatherford’s standard well test separator is a three-phase horizontal design that efficiently separates the well effluent into three constituents (gas, oil, and water) to enable these processed fluids to be individually measured and directed for collection, burning/flaring, or controlled disposal, depending on the application. Separator operating parameters will vary according to the fluid type and flowing conditions for optimized separation and is achieved by controlling pressure and fluid levels within the vessel. Temperature, controlled upstream of the separator, is another important factor. The fixed internal components inside the separator vessel (inlet diverter, baffle plates, weir, coalescer/defoamer, and demister) also assist in this process. Once stable process conditions prevail, gas, oil/condensate, and water rates can be measured in the gas and liquid meter runs on the separator outlet lines. The vessel is protected from overpressure by two independent safety relief valves on a contained vent line.

Applications• Offshore and land operations

• Drillstem testing

• Well cleanups

• Production/well testing

• Early-production facilities

Features, Advantages and Benefits• Pressure, temperature, and sampling ports on inlet

and outlet lines enable maximum measurement and sampling in all phases.

• Full-bore bypass manifold with isolation valves enables routing of inlet effluent to gas, oil, and water outlets.

• Check valve fitted to vessel inlet nozzle.

• Configuration and flexibility of internal components allow use of a standard manway.

• Pressure safety valve on vessel with relief line to edge of skid, diagonally opposed grounding points on base-skid, and explosion-proof lighting at the front and rear of the unit enhance operational safety.

• NuFlo™ liquid meters enable analog and digital recording options.

• Flanged adapter spools provided to allow retrofit of alternative liquid meter types.

• Flanged nozzle provision on vessel to allow optional Hi-Lo pressure and level alarms and shutdown sensors.

• Internally coated with Belzona® 1391 for protection and extended vessel life.

• CSC/DNV certified frame and skid enable stacking of units for increased durability and mobility.

• Four-point lifting sling and integral forklift pockets provide flexiblility to handling and movement.

• Skid-mounted tool box containing ancillary equipment improves operational efficiency.
