NIGK21005U Geological Evolution Based on Interpretation and Integration of Reflection Seismic and Wireline Log Data
In this course, the students learn how to understand sub-surface geology by integration and interpretation of digital reflection seismic and wireline log data using professional software at workstations. The seismic data is interpreted by the method “seismic stratigraphic interpretation” that can be used to interpret e.g. reflections seismic data, high resolution seismic (sparker and Chirp) and GPR (Ground Penetrating Radar) data. The wireline log data (e.g. Gamma-ray, Sonic, Density, Porosity and Resistivity) are interpreted using principles of wireline log interpretation e.g. electrosequence analysis. The combination of the two methods allows for an understanding of the 3D sub-surface structures and the lithology
The course is based on interpretation of reflection seismic data, theoretical and practical aspects of reflection seismic interpretation and interpretation of wireline log, theoretical and practical aspects of wireline log interpretation leading to an integrated interpretation of digital seismic and wireline data in a geological basin.
