- Collapse of cavities?
- Extremely irregular, often pinnacled surface of fresh rock?
- Sharp boundary between residual soils and fresh rock?
- Strong rock around solution tubes and cavities in weak, porous rocks?
- Solution cavities in altered carbonate rocks or metamorphosed impure carbonate
rocks?
-Very weak, low density, erodible weathered materials?
- Extremely high permeabilities?
- Extreme variations in permeability?
- Possible deep, major leakage paths out of reservoir?
