Determining of the orientation and nature of fractures in cores is important for studies of hydrocarbon flow, tectonic history and in-situ stress in reservoir formations. Fracture orientations in cores are usually measured by core goniometry and COREMAGNETICS provides a full service in this field. Specification of the directions relative to North requires that the cores be re-oriented. This can be done quickly, conveniently and economically by the paleomagnetic re-orientation method.
