The “PIK-/OFP-K-320” equipment complex for high-temperature research in acid-resistant performance

The PIK-OFP-K-320 complex is designed to study filtration, capacitive, elastic and electrical bulk model properties at reservoir conditions under stationary and non-stationary two-phase filtration when studying high-viscosity oils displacement processes by hot water, steam and chemically aggressive environments. The complex is equipped with high-temperature unit, including steam generator-superheater, heat-insulating box and temperature control system. Pore fluids (oil, water) filtration can be performed in forward and reverse directions.
