Filter Cake
Filter cake is the compacted solid or semisolid material remaining on a filter after pressure filtration. Filtration is a process used in a variety of industries so the content of filter cake varies greatly but often it is nutrient rich and beneficial to recycle. If the filter cake content is non-toxic then recycling filter cake can recover ...

Facts At Your Fingertips: Cake Filtration Basics
FIGURE 1. In cake filtration (a), the separation takes place on a buildup of particles (cake) on the filter medium. In some cases (b), more than simple size exclusion may be involved. The sub-micron, non-haze particles shown in the figure also are not retained, but this is expected because these particles are smaller than the pores in the …

A simple NMR methodology for evaluating filter cake
An efficient drilling fluid will form a filter cake that will minimize the drilling fluid invasion into any drilled formation. Drilling fluid must therefore be adequately evaluated in the laboratory prior to field trial. Filter cake properties such as thickness, porosity, permeability, and pore structure are frequently evaluated using several techniques such …

Filter Cake
The filter cake formed by drilling fluid is a thin layer deposited on a permeable surface, i.e., formation wall. Generally, the filter cake coats the borehole wall and restricts drilling fluid to invade the formation, thus preventing formation damage or permeability impairment (Civan, 2016 ). It is expected that the filter cake should be ...
