Liquid-Liquid Unsteady State Relative Permeameter
UPR is designed in a way that it is able to perform different injection protocols to measure the relative permeability by different analysis methods including Johnson-Bossler-Naumann (JBN), modified JBN, Toth, et al and the Jones-Roszelle methods. The unsteady-state method is particularly suited for measuring endpoint values of the non-wetting phase. The URP-ES20-ES30 system provides a versatile facility to carry out unsteady-state relative permeability studies for liquid/liquid at reservoir temperature and pressure.

Wettability Alteration Chamber
Read moreThe wettability alteration chamber is designed for the purpose of core wettability restoration prior to SCAL studies. The changes in wettability are obtained by subjecting the core to reservoir conditions of temperature and pressure for weeks. At this stage, a wettability transition may occur in the oil-invaded pores depending on the stability of the thin water films, located between the pore walls and the oil.
