报告简介:

     Hydrogeology in the deep subsurface is highly heterogeneous. There is strong variations in rock transmissivity and in water chemistry or salinity. Under non-equilibrium flow conditions, the system will also display spatial variation in hydraulic pressure. To understand such a system it is important to be able to have in situ data from a borehole on the rock transmissivity, water salinity and hydraulic pressure as a function of depth. Flowing fluid electric conductivity (FFEC) logging has been shown to be effective to obtain such data for both porous medium and fractured rock in a short time period without the need for highly specialized downhole probes. The talk will introduce the FFEC logging method and present a recent application to a 2.5 km borehole in fractured rock in Sweden, together with some recent development of a simple direct method to measure hydraulic pressure heads of transmissive zones in the subsurface.
