Abstract
Japan Metals and Chemicals Co.,Ltd.(JMC) and its related company have three geothermal power plants, that is, Matsukawa (22MWe), Kakkonda (Takinoue) Unit 1 (50MWe) and Mori (50MHe), and are currently developing Kakkonda Unit 2. JMC is also concerned with developing of La Primavera, Mexico and San Kampaeng, Thailand. These geothermal fields are all characterized by fractured reservoir consisting of open fractures in compact and hard rocks. To evaluate fractured reservoir, JMC has accepted a combination method of fracture mapping as follows: 1) Detection of each individual fracture around borehole 2) Survey on extension of fractures 3) Recognition of fracture pattern
