..., especially in areas of strong stress anisotropy. This paper focuses on the acquisition of good quality stress data through casing essential for a geomechanical analysis of the caprock using sonic and cement/borehole imaging tools. Since azimuthal sonic data is very sensitive to acoustic anisotropy...

... alternative solutions have to be sought. Detailed computer simulation, using compositional numerical model software CMG-GEMGHG, was used to study the effects of aquifer anisotropy (heterogeneity), well completion technique (perforation and well orientation), brine production and injection rates on CO 2...
