“…They concluded that their attenuation-based rock physics templates derive better lithology and fluid separation results than conventional v p / v s -acoustic impedance rock physics templates on the considered dataset. Tucovic et al (2016) created resistivity-acoustic impedance rock physics templates based on deep reading logging while drilling data as a foundation for further work of real-time template-based logging while drilling interpretation for enhanced geosteering operations.…”

In this study, the ratio of compressional and shear wave velocity versus acoustic impedance as rock physics template for northern part of the Vienna Basin has been derived for siliciclastic rocks based on formation evaluation of well-log data. The results have been verified through wells in different areas drilled in various depths. Additionally, depositional sequences like prograding deltas and braided rivers have been plotted onto the rock physics template to illustrate the effect of changing shale volume. Carbonates below the basin have been included into the study and results from previous projects, based on laboratory data and petrophysical models on certain lithologies in the Vienna Basin, have been used to compare the outcome. The result is a rock physics template which includes important properties such as porosity, true vertical depth and fluid type from log data and which is considered useable throughout different areas and various lithologies of the Vienna Basin.
