Sažetak
Fractal patterns occur in many fileds of geosciences. Some geological objects that concern reservoir properties and follow fractal pattern are 1) fracture and fault network of hard rocks, 2) grain size distribution in fault breccias, 3) fracture wall roughness, 4) grain surface roughness, 5) grain boundaries (sutures) in monomineralic rocks (e.g. quartz-quartz), 6) composition pattern of zoned cement minerals (e.g. carbonate) among many others. The common feature of all these geometrical objects is that although they appear as seemingly random, they are not. All fractal like patterns are scale independent and follow either self-similar or self-affine behaviour. From this aspect fractal patterns identified at any magnification can be used for prediction the same pattern at other scales. Understanding fractal-like geological objects and basic knowledge of the methods of fractal geometry can be used for better understand reservoir characteristics both along well trajectories and in the inter-well area. The most essential questions one can answer using fractal behaviour of diverse scale invariant objects are as follows. Fracture networks can be simulated at reservoir scale and can be used for computing hydrodynamic properties. Genetic characterisation and consequently reservoir properties of fault breccias are based on fractal geometry behaviour of size distribution and shape of grains. Zonation patterns of cement minerals are in direct relationship with paleohydrological activity of the veins and suggest flow velocity. These and many other important questions are to be discussed in the frame of the Workshop of the Conference.
