OAS is responsible for the design and development of oil logging tools, optic-based sensors and sensor technologies.

The team members come from varied backgrounds, and have experience in sensing technologies, optical electronics, physics, electronics, machinery and software. These team members all work together to develop tools in close communication with overseas research/technology centers and oilfields. With members from five different nationalities, OAS offers a truly global working environment.

In the early 1990s, OAS was the first in the world to succeed in obtaining spectrographic analyses from inside high temperature and high pressure oil wells.

Optical Fluid Analyzer (OFA) is the first commercialized optical tool from Schlumberger and has earned an excellent reputation from its customers. Since then, OAS has continued to develop optic-based tools in Japan.

Crystal Quartz Gauge is produced at SKK and is now being used by Schlumberger worldwide. This highly sensitive, robust gauge with a performance said to be the best in the industry, delivers extremely accurate and rapid measurements of wellbore pressures. Such accurate pressure information allows oilfield operators to calculate important factors such as the production potential of oil-in-place and enables them to conduct long-term monitoring of the field’s production performance.

Our next goal is to develop smaller sensors that offer greater performance and greater functionality.
