Rock stress measurements in the deep boreholes at Kuhmo, Hyrynsalmi, Sievi, Eurajoki and Konginkangas

Abstract

Hydraulic fracturing rock stress measurements, conducted in five boreholes are presented. The boreholes are located in different site investigation areas in Finland: Kuhmo-Romuvaara, Hyrynsalmi-Veitsivaara, Sievi-Syyry, Eurajoki-Olkiluoto and Konginkangas-Kivetty. The aim of the measurements was to provide rock stress data, forming input to the site selection process for an underground facility for disposal of high level radioactive waste from the Olkiluoto Nuclear Power Plant. A summary is given of the theoretical background to the hydrofracturing method, whilst the equipment and experimental procedures used in the present case are described in more detail. All results obtained are presented and subjected to critical discussion. The final stress parameters evaluated are magnitudes and directions of the maximum and minimum horizontal stresses. Testing was successfully completed according to the clan at Syyry, Olkiluoto and Kivetty. Testing was partly successful at Romuvaara but unsuccessful in the borehole at Veitsivaara.
