Mudcake permeability - Formation invasion
Input(s)
\(\mu\): Viscosity \((\mathrm{cP})\)
\(h(t)\): Filtrate Height (in.)
\(x_{c}(t)\): Mudcake Growth by time (in./s)
\(\Delta p\): Pressure Change (psi)
\(t\): Time (s)
Output(s)
\(k\): Viscous Shear Stress at the outer Mudcake boundary (lb/in. \({ }^{2}\) )
Formula(s)
\[
k=\frac{\mu \cdot h(t) x_{c}(t)}{(2 t \Delta p)}
\]
