Web1 dec. 2024 · Solids that are soft, slimy or gelatinous tend to pack tightly, forming cakes of low permeability. This problem can be alleviated by the addition of a small amount of filter aid to the feed slurry. Filter aids are inert, highly porous materials that act to separate blinding solids, leading to a more open cake and in turn a higher filtration rate. WebDuring oil wellbore drilling processes, filter cake is formed on the sidewalls of the well hole due to filtration of drilling fluid particles. The filter cake is crucial to the drilling process, since it helps to maintain the wellbore hole, protects.
