Comparative Analysis of Shale Permeability Measurements

Gas has proved to be a successful extractable hydrocarbon resource from shale in the United States. In Europe results have so far been disappointing, but with increasing global energy demand a lot of interest remains in the potential of recoverable shale gas reservoirs. However, the way how the economic potential of shale is mapped is...

NMR Applications in Petrophysical Characterization of Shale Gas Formations

This thesis consists of multiple approaches to develop a new model to determine the porosity, permeability and the rate of desorption of 1.5-inch shale samples. The raw NMR signal of the sample in the coreholder is measured before methane injection and is used as base signal. During the injection of methane the raw NMR signal increases. The base...
