Tohoku University Technology: Rock core orientation method by image analysis: T20-3110
Possible to orientate rock core objectively and automatically
Cylindrical rock sample (rock core) taken from a well is analyzed for underground resources exploitation. Analysis of rock core can be used to estimate subsurface material and to measure physical property of formation in a simple way at low cost. Moreover, if the orientation of rock core at in-situ status is known, it is expected to estimate information on the formation, such as the direction of crustal stress, the anisotropy of permeability and the direction of subsurface fault. There is a conventional method to orientate rock core by tracing the borehole image taken by logging and matching it with the surface image of the rock core. This method takes a long time and leads to a subjective conclusion since the orientation is determined visually. This invention is about a method to orientate rock core by image analysis, which enables orientation in a shorter time with an objective process than conventional method.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
