Abstract
A computationally efficient general method of modeling or simulating matrix acidizing treatment when flow is not axisymmetric involves determining streamlines in the general flow field using complex potential theory to solve for the flow along the streamlines. The flow over a time step is used to model the propagation of the acid front and the creation and extension of wormholes.
