The disadvantage of API filtration test to evaluate mud cake quality is analyzed. A method, taking mud cake strength, permeability and thickness as main evaluation factors is introduced.
Filtration media is required to have suitable pore size, pore size distribution, pore volume, pore surface area and permeability for performing satisfactorily in applications.
