A simple and accurate model of foam hydraulic fracturing is developed with both
compressibility and rheology being taken into account. The governing equations for a
compressible power-law fracturing fluid are derived for the classical PKN fracture geometry.
Numerical simulations reveal an influence of compressibility and rheology on the temporal
evolution of the fracture opening.
