Seismic Reflection Interpretation

James N. Kellogg Ph.D.
Descripción del instructor

Dr. James N. Kellogg, is a Professor in the Department of Earth and Ocean Sciences, Director of the Andean Geophysical Laboratory, at the University of South Carolina, (AndeanGeophysical.com) and is Editor-In-Chief of the Journal of South American Earth Sciences. Jim pursued geophysical and structural studies of the northern Andes, funded by the Venezuelan Ministry of Energy and Mines, for his M.A. (1978) and Ph.D. (1981) in geology and geophysics at Princeton University. In 1987 he joined the faculty of the University of South Carolina as professor of applied geophysics. His principal research interests include geodetic, gravity and tectonic studies of active margins and the Andean orogenic belt where he has worked for the last 30 years. He was Principal Investigator for the GEGEO (Guinea Equatorial GEOscience) Program, the Central and South America (CASA) GPS Geodesy Project, and the Colombia, Peru, and Bolivia Geophysical Projects. Dr. Kellogg’s research has been published in over 60 peer-reviewed articles.

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.
