The circulation test had three phases. The first phase is the deep reservoir injection with constant injection rate, the second phase is dual reservoir injection and the third phase is a power generation using the binary system. During the two year-test period, we continue microseismics monitor, geochemical sampling and environmental monitoring. In addition to these monitoring, we ran PTS logging once every six weeks and also did tracer tests in time with PTS logging. Research Center
