摘要

A set of repeat self-potential (SP) surveys was conducted at the Matsukawa geothermal field, Japan for the purpose of detecting the change of subsurface fluid flow system in a vapor dominated reservoir caused by well operations. Surface SP was measured around the reservoir range before and after shut-in of the wells for annual maintenance. As a result, change of SP at several measurement points, which may correspond to the phase change of subsurface fluid and the change of flowing direction of liquid phase, was observed near the main reservoir area. Thus SP monitoring can be applied for vapor-dominated reservoir to investigate the existence of liquid phase around the reservoir.
