Inversion of geothermal parameters using borehole and core data
This thesis analyses the inversion of petrophysical and temperature measurements for the study of geothermal problems. The inversion of temperature data and the inversion of petrophysical measurements are first considered separately, then jointly by introducing a new algorithm for the combined …

Die syn- bis post-magmatische Entwicklung des Mauna Kea/Hawaii, USA : Interpretation geophysikalischer Bohrlochdaten und petrophysikalischer Kerndaten aus der Tiefbohrung 'Hawaii Scientific Drilling Project, HSDP-2'
In 1999, an extensive logging program with standard logging tools was run by the GFZ Potsdam in the scientific drillhole ‘Hawaii Scientific Drilling Program - HSDP-2’ on the island of Hawaii/USA. Measurements of electrical resistivity, gamma-ray activity, and Vp-velocity were performed in an …

Heat transfer processes in the upper crust: influence of structure, fluid flow, and palaeoclimate
Numerical models constrained by geological and geophysical data form the basis of understanding the thermal regime of the Earth's crust. This dissertation focuses on modelling heat transport in the upper crust, studying the relative contributions of different processes to the specific heat flow …

Mobile NMR for rock porosity and permeability
Three different mobile Nuclear Magnetic Resonance (NMR) core-scanners were used to measure porosity and permeability of water-saturated drill cores and core plugs in a non-destructive way. In addition to their use in the laboratory, the small and light-weight devices are conveniently shipped, e.g. …
