Abstract
Methods and systems for evaluating the subterranean formation of a wellbore are provided. In one embodiment, a geographical orientation of a downhole tool relative to Earth may be determined. The downhole tool may include a coring tool positioned to extract a core sample from a formation of the Earth. The orientation of the core sample with respect to the downhole tool also may be determined. Further, based on the geographical orientation of the downhole tool and the orientation of the coring sample, a geographical orientation of the core sample with respect to the Earth may be determined.
