Capillary Pressure and Resistivity System

Function. Performs drainage and imbibition experiments on core at reservoir conditions while simultaneously measuring the rock electrical resistivity.

Controlled. Confining and capillary pressure; temperature; electrical excitation.

Measured. Capillary pressure, saturation and resistivity index.

Sample count, pressure and temperature ratings, wetted materials, seals and instrumentation are configured per project. Guaranteed performance and included hardware are stated only in the project-specific technical proposal and approved datasheet.

Features

• Maximum confining pressure: 700 bar (10, 000 psi)
• Max pore pressure : 700 bar (10,000 psi)
• Working temperature : up to 150°C
• Capillary pressure range: -10 to +10 bar (145 psi)
• Core length : 2” up to 3”
• Core diameter: 1 ½” other upon request
• Power supply: 220VAC, 50Hz
• Brine wetted material : stainless steel (option Hastelloy)

Benefits

• Measurements are made at reservoir conditions of pressure and temperature
• Direct capillary pressure measurements
• High-temperature pumps located in the isothermal air bath are used to prevent temperature related volume measurement errors
