Idea: monitor heat output per pumped volume. Difference between end of heating cycle (cooled down) and start of heating cycle (natural reservoir recharge) can give indication of heatflow.

manifestation of temp. anomalies due to unusual EWS output?

Idea Daniela

lead: Fachhochschule Yverdon, Daniel Pahud; oder Geotest, Badoux
execution ???????

During concept phase only write technical concept for an effective monitoring solution and prove technical feasability of measurement.

heatflow anomalies due to advection

exploration for hidden geothermal systems

methodology Badoux-Kuhn-Niederau

automated statistical determination of outliers against background conductive heatflow. manual analysis of cause for outliers: a) bad temp measurement b) bad determination of conductivity c) advective heat transport. c)=bingo. if c) look for identical signal of nearby wells. if no nearby well--> focus for data acquisition

execution: same PosDoc as Hydro? or Benoit himeself? collabo with structural analysis

# data[].attributes.body
for one play

Allows better extra- and interpolations, taking geology into account instead of symmetric linear equations.

Larryn: for Muschelkalk not relevant, done by a PhD. we can put it into database.
Larryn knows how much work and money is needed for facies maps of other plays for realisation phase.
