ABOUT COURSE
COURSE OBJETIVE
Students will learn seismic interpretation skills through hands-on mapping of 2-D seismic data. Exercises will involve recognition of pitfalls in seismic interpretation, and the correlation of synthetic seismograms and well log data with seismic sections. Laboratory exercises will include application of the “kink method” of interpretation to extensional and compressional structures and the interpretation of the evolution of salt structures. The course will introduce the use of seismic attributes for reservoir characterization and the interpretation of 3-D seismic data. For the final project, students will generate and integrate fault and horizon maps, methods important for the location of exploration and development prospects and wells.
LEARNING OUTCOMES
- Knowledge of common mistakes in velocity, geometric, and processing interpretations.
- The basics to tie well log data to seismic sections and correlate synthetics with seismic data to establish geologic horizons.
- Recognize and interpret compressional (fault-bend folds and fault propagation folds) and extensional structures (roll over anticlines).
- Interpret seismic data for salt structures.
- Generate time and depth structure maps from seismic data.
COURSE CONTENT
Lab Exercises: Most exercises will use 2-D paper seismic profiles, but they may also require Kingdom Suite for 3D seismic interpretation and Geosec 2.5D for volume-balanced structural interpretations.
