Abstract: 

While the dip of structural features on recovered rotary-drilled core can be accurately measured, the azimuth of such features in a geographical reference frame is not known. Scribing techniques and analysis of magnetic signatures have been used in attempts to solve this problem, but scribing has so far failed in deep-sea drilling operations and magnetic signatures cannot always be easily resolved. Here, we demonstrate a method for core reorientation and accurate location within a borehole using a comparison between borehole electrical images and whole-core digital images.
