The “PIK-OFP-FD” equipment complex for assessing reservoir damage by injected fluids, drilling fluids

The PIK-OFP-FD complex is designed to determine filtration, capacitive and electrical core sample properties at reservoir conditions with stationary and non-stationary filtration and allows simulating process fluids impact on bottomhole reservoir zone.

Core holder plungers design provides process fluids pumping along sample end to form a colmatant crust. Core holder is equipped with several differential pressure measurement ports that allow user to evaluate pressure distribution along the core sample (samples column).

High-capacity pumps set provides process fluids continuous circulation. Special containers for process fluids are equipped with mixing system preventing solutions solid phase settling at reservoir conditions.

 Base fluid filtration can be performed in both forward and reverse directions. Installation elements can be made of acid-resistant chromium-nickel alloys (Hastelloy C-276) to assess the effectiveness of colmatant crust and core samples acid treatments.
