“Doctor to the Earth” started from researching precisely by ourselves.

Our first laboratory opned in 1957, just 2 months after the foundation of OYO. We had a firm policy that “Doctor to the Earth” starts from researching subsurface precisely by ourselves, and regarded testing technologies and investigation technologies as inseparable.

Currently OYO continues research and development in Core-Lab and Tsukuba Research Center. OYO also has “OYO Bionomical Engineering Research Center” in Miharu-machi, Fukushima to research changes in water quality, bionomics, and climates before and after the inundation of Miharu Dam.

 

Core-Lab

Core-Lab was established in 1992. The name of “Core-Lab” means not only that this is the “Laboratory” of the “Core” collected from borehole sites, but also that OYO is aiming the “Core” of the technologies for assessing ground properties.

Core-Lab is one of the biggest private laboratories, and it has facilities regarding soil/rock tests and chemical analysis in testing rooms of 3,000 m2 in total.

The recent highlight in Core-Lab is to build up testing equipment to generate Methane Hydrate and to reproduce subsea conditions in the depth of more than 1,000m for physical property tests of Methan Hydrate. In addition, testing equipment for CCS (Carbon-dioxide Capture and Storage) has been designed, and research on relationships between rocks, seawater and CO2 is ongoing.

As above, Core-Lab has achieved the most advanced, complicated, or high-accuracy tests that nobody has ever done. It is essential for acquiring reliable testing results to improve and maintain on-site sampling technologies as well as tesitng. OYO has developed a high quality boring system, and is currently applying a patent.

Tsukuba Research Center

In the early days of OYO, it developed necessary equipment for geological survey by itself because there was no good equipment at that time. After that, our instrumental business started because some invstigation companies requested us to sell the developed equipment.

Now, OYO has more than 100 products, based on the spirit of “making necessary equipment by ourselves”. The equipment for LLT (Lateral Load Test), which acquired a patent in 1965, is still our main product, and has been sold approximately 2,000 until today. The instrumental division was reorganized to “Instrumants & Solutions Division” in 2007, and  not only conducts developing equipment, but also provides services and supports including developing systems. OYO’s instruments are utilized worldwide not only for geological survey but for wider areas, such as disaster mitigation/prevention, operation & maintenance, and environment.

For testing and certifying instruments, there are 4 boreholes which depths are 50m, 150m, 200m, 300m and 1,350m. In addition, there is a radar calibration facility for diagnoses of cavities and deterioration of roads, tunnels, and bridges.

OYO Bionomical Engineering Institute

“Bionomical Engineering” means the technological area between bionomics and civil engineering, which forecast and evaluate how civil engineeting affects changes in natural environment, particularly ecosystems. OYO is studying and researching such an area as “Bionomical Engineering”.

OYO Bionomical Engineering Institute was established near from Miharu Dam, Fukushima in 1999. However, the research started from 1995, the previous year of the inundation of Miharu Dam.

The Institute is researcing the following 3 areas: 1) Studying long-term changes in ecosystems and micro climates, 2) Understanding actual situations of pollutant load in the catchment area, 3) Developing a boundary area between bionomics and civil engineering. We are presenting the results of the research to academic societies or associations, for instance , developing ” A Method capturing fish and a fixed net used for the method” (Patent No. 3822878), and a paper titled “Changes of woods in a lakefront assiciated with an appearance of a pond”.

On the other hand, for improving environment surrounding the dam lake, the Institute joins “Natural Environment Forum in Lake Sakura”, which started from 2000, as a member of the executive committee every year.
