Abstract

An OpenFOAM solver has been developed, capable of modeling buoyancy, advection, diffusion, and reaction of acid in geometries consisting of both fully fluid and heterogeneous porous media regions. Furthermore, the dissolution of porous media and with it the transition from DarcyForchheimer to fully fluid flow is accurately captured. With this solver, along with meshing schemes capable of constructing geometries consisting of fully fluid, porous media, and unaffected solid regions from three-dimensional CAD drawings, the impact on wormhole formation and directionality is shown to depend heavily on: Fluid properties, flow characteristics, and domain geometry. The importance of modeling three-dimensional domains, as opposed to two-dimensional domains is also observed. Full well completion models, including liner, perforations, and heterogeneous porous media, were analyzed to assess the feasibility of affecting wormhole directionality with heavy acids.
