High DP Multiphase Test Facility

Operating Conditions

  • Gas source maximum pressure: 3,000 psig
  • Gas source volume: 1,125 ft3
  • Test section upstream pressure controlled up to approximately 2,800 psig (dependant on flow rate)
  • Test section differential pressures over 2,000 psi
  • Gas flow rates in the range of approximately 0.02 MMScfd to 10 MMScfd
  • Liquid flow rates up to ~30 gpm (~1,000 bpd)
  • Gas volume fraction: 0% to 100%
  • Water cut: 0% to 100%
  • Flow duration dependent on gas flow rate and test section upstream pressure
  • Temperature: ambient (no active temperature control)

Fluids

  • Gas: nitrogen
  • Liquid: fresh water, saltwater, light mineral oils, refined liquids

The High DP Multiphase Test Facility gas source is from the Gas Blowdown Facility.

The test article is installed in the test section indicated by the dashed box in the schematic. Various tool lengths can be accommodated, and horizontal and vertical installation configurations are available.

Facility Schematic

As shown in the facility schematic to the right, the gas-phase flow is provided by high pressure nitrogen gas flowing though the facility and is exhausted to atmosphere. The liquid phase flow is provided by a triplex pump in a recirculating, open tank loop. Click the image for a larger view.

Complementary Technologies

  • A wide range of expertise in complementary technologies are also available, such as noise and vibration, that can be utilized for various projects.
