Filter Cores for Dynamic HPHT® Filtration System

Shale Tech Solutions SRL distribuidor exclusivo de FANN para la Argentina

Designed for conducting filter cake formation and permeability analysis  

Fann engineers designed special filter cores for the Model 90 Dynamic HPHT Filtration System to conduct filter cake formation and permeability analysis. 

The filter medium is a thick-walled cylinder with rock-like characteristics to simulate the build-up of  filter cake on the formation.  This provides more accurate filtration measurements. The entire internal length is subjected to pressurized fluid (sample). Filtrate flows through the core radially from the inside to the outside.

The filter medium is available in varying porosities and permeabilities to simulate down-hole formations.

Filter Cores are supplied in boxes of 10 cores of the same porosity.
