SRP350-Bench top unsteady and steady state relative permeameter


The versatile SRP350 flawlessly performs both unsteady-state and steady-state liquid/liquid and liquid/gas relative permeability determination studies on plug-sized core samples at reservoir-representative pressure and ambient temperature. A core plug is fitted into a Viton sleeve and inserted in a hassler core holder. Liquid phases are injected and recirculated through the core sample at different constant flow rates while gas phases are injected either at constant pressure or at constant flow rate using mass flow controllers. Saturations are deduced from produced volume measurements in a video separator. In the S.S. mode, absolute or relative permeability is determined via the Darcy method, whereas the U.S. method makes use of the standard Jones and Rozelle equations.
