Unsteady state flow apparatus

Apparatus for unsteady-state flow in porous media at reservoir conditions

This apparatus is dedicated to unsteady-state relative permeability measurements. It is capable of core flooding at reservoir conditions, and the recirculation system allows the tests to continue for as long as desired.

Major features of the apparatus:
  • Unsteady-state two- or three-phase flow through porous media.
  • Accurate and continuous fluid injection.
  • Flow rates from 1 l/min to 10 ml/min.
  • Operates at reservoir conditions; up to 70 MPa and 160 C.
  • Two- or Three-phase separator for average saturation determination.
