SYSTEM AND METHOD FOR INSTALLATION AND USE OF DEVICES IN MICROBOREHOLES

摘要

Making measurements with a main borehole and a microborehole extending from the main boehole into the formation, is performed with sensing devices positioned to measure at zones located in the microborehole. One or more packers can be installed in the microborehole to hydraulically isolate the measurement zones from each other and/or main borehole. In a microborehole fluid samples can be taken, fluid tracers be injected and various sensors including geophones can be incorporated.
