... Stratigraphic sequences are sometimes thin, rarely horizontal and juxtaposed due to faulting. Wellbore trajectories in such strata may not lie along principal stress direction. Perforations for hydraulic fracturing may also be inclined to the principal stress direction. Fundamental understanding...
