Sonic Scanner has been recently introduced to the market. This is the first 3D sonic logging tool developed in Japan. It measures sound slowness(1/velocity) of P and S wave along well axis, around well bore and away from well bore. There are many applications including drilling related applications. One example is “damaged zone” identification. Sonic Scanner is the latest example of logging tool developed in Japan, and there was a history to achieve such advanced tool development. It's been 70 years since the first electrical log was run in Japan, and it's been 50 years since logging service was brought into Japan. Schlumberger opened Engineering and Manufacturing center facility in Sagamihara 20 years ago, and started tool development. The reason Schlumberger opened such center in Japan was to capture Japanese leading technology and manufacturing quality and apply to oil field. One of the examples is color printer for oil field use, which was 20 years ahead of consumer market. The trend to capture leading edge“enabling” technologies to apply them to increase efficiency of oil field development will continue. To do that, we need to work with such technology providers that may be another strong industry in Japan or Academic community.
