abstract = {<p style="text-align: justify;">We present an $H^1$-Galerkin mixed finite element method for the
solution of a nonlinear parabolic pressure equation, which arises in the mathematical
models for describing a compressible fluid flow process in subsurface
porous media. The method possesses the advantages of mixed finite element
methods while avoiding directly inverting the permeability tensor, which is important
especially in a low permeability zone. We conducted theoretical analysis
to study the existence and uniqueness of the numerical solutions of the
scheme and prove an optimal-order error estimate for the method. Numerical
experiments are performed to justify the theoretical analysis.</p>},
