Äspö Hard Rock Laboratory; Using borehole tides to determine fracture parameters; 1 - Theory, pre-study and literature survey

The possibility to use tide observations in boreholes to determine fracture parameters is investigated. This report is the first part of two, and presents the theoretical background and a pre-study. Well tides have clearly been observed in the KAS03 borehole located at Äspö. A time series is analysed from this location. Basic concepts are developed along with a review of the relevant literature. The second part will report the results from estimation of tidal parameters and inference of parameters of a fracture zone model, using observations from 40 different boreholes or borehole sections at Äspö.
