We explore tracer breakthrough profiles (TBP) as a macroscopic property to infer the porespace topology of tight gas sandstone and carbonate rocks at the core scale. The following features were modeled via three-dimensional multiscale networks: microporosity within dissolved grains and pore-filling clay, cementation in the absence and presence of microporosity (each classified into uniform, porepreferred, and throat-preferred modes), layering, vug, and microcrack inclusion. A priori knowledge of the extent and location of each process was assumed to be known. With the exception of an equal importance of macropores and pore-filling micropores, TBPs show little sensitivity to the fraction of micropores present. In general, significant sensitivity of the TBPs was observed for uniform and throat-preferred cementation. Layering parallel to the fluid flow direction had a considerable impact on TBPs whereas layering perpendicular to flow did not. Microcrack orientations seemed of minor importance in affecting TBPs.

“…Many networks can be "glued" together using mortar coupling. Mehmani et al (2012) used mortar coupling to simulate reactive transport of CO2 in 64 separate pore networks coupled as one large domain (Figure 8). Precipitation of reactants reduced throat sizes and therefore permeability.…”

Carbonate reservoirs represent a significant portion of global hydrocarbon reserves. Injecting strong acids around the wellbore of carbonate wells can significantly increase near-wellbore permeability. A pore-network model is developed to capture permeability response of carbonates to acid stimulation. A novel pore-scale mass-transfer coefficient and pore-merging criterion are developed using finite element simulations. Preliminary results are able to reproduce the expected trends in permeability increase and capture the gamut of different dissolution regimes. Future work will focus primarily on using advanced subdomain coupling techniques to simulate much larger domain sizes to investigate the effects of domain size and determine a representative elementary volume.
