Abstract
Karst is a generic term for the effects of meteoric (rain) water<br>on carbonate rocks. Resulting features include rock<br>dissolution, conduits, sink-holes, etc, which may have<br>extremely high permeability. Fluid flow simulations in such<br>environments are therefore very challenging – conventional<br>reservoir simulators often experience convergence problems<br>and run times of several days are not uncommon even for<br>models with a modest number of grid cells.
