RPS-300 Automated Reservoir Conditions Relative Permeability System 

The Automated Reservoir Conditions Relative Permeability System allows for the recirculation of live fluids to maintain rock-oil-brine chemical equilibria, and thus wettability, leading to the production of more representative relative permeability curves and thus realistic reservoir production predictions. Live fluids are retained and can be reused after the experiment. 

Proprietary software allows for the ramping of individual pumps to achieve true pulse-less transitions by adjusting system pressure and flow rate. The circulation is driven by two dual cylinder Sanchez Technologies Stigma pumps that recirculate the fluids while an additional single cylinder pump is used to maintain constant pressure in the recirculation system.  

The AMS-300 HPHT acoustic separator is employed to record real-time volumetric data with an accuracy of 0.01cc or better. 

The unit is fully customizable and can be configured for confining pressures up to 20,000 psig, pore pressure up to 15,000 psig and temperatures up to 300 °F (150 °C) with Viton seals. For temperatures up to 430 °F (200 °C) Aflas seals and sleeves are used in place of the Viton. Automated data acquisition and logging of pressures, temperature, flow rate and volumetric data with automated file back-up is controlled by the operating software.
