The constant property (incompressible) and variable property (compressible) filter cake models considering nonDarcian linear and radial flow conditions are facilitated for estimation of the filter cake thickness and the fluid loss into high permeability formations. These models can be applied for analyses of the filtration problems associated with the drilling, hydraulic fracturing, and workover operations.

The parametric studies demonstrate that nonDarcian flow conditions are more dominant during the build-up of incompressible filter cakes over high permeability formations without involving fine particles invasion and retention. The non-Darcian effects rapidly diminish for compressible cakes undergoing fines deposition within the cake matrix.
