Deep borehole temperature profiling around dams in Sweden

This site is located near Lac la Biche, Alberta, Canada is a similar application. CS225s were installed in ground water wells, and surface stream-waters beside oil boreholes. The CS225s monitor for hot water leakage resulting from the oil extraction process.

Recently, the Swedish government introduced new legislative guidelines related to health and safety around dams, as Sweden has many dams in specific regions. Temperature profiling is often conducted to measure the possible seepage of dam water using deep boreholes that surround the dams. A change in temperature of the surface or ground water can indicate a leakage in the dam walls. Various Swedish clients have investigated installing the CS225 Temperature String down boreholes to help them monitor borehole temperature profiles near dams. The CS225 Temperature String is a ruggedly built temperature profiler that can be completely customized to fit the users measurement requirements. It can be buried and submerged, making it ideal for deep borehole temperature profiling applications; and it looks like the CS225 is quickly becoming the standard for this application in Sweden.
