ABOUT COURSE

 

This course provides an understanding of the evolving role of seismic petrophysics through the use of amplitude variations with offset or angle (AVO/AVA), attributes, and inversion techniques.  Understanding rock physics and the behavior of the propagating seismic waves represents an integral part of the course, especially in the context of specific applications including enhanced seismic interpretation, rock and fluid characterization, including hydrocarbon identification and quantification, fracture identification, and stress/geomechanical analysis.  Course concepts are enhanced by numerous practical exercises and case studies.

 

COURSE OBJECTIVE

  • The fundamentals of seismic wave propagation and specific attributes of seismic measurements toward enhanced interpretation and petrophysics.
  • The benefits and cons of various attributes in various facets of investigation, including stratigraphy/sedimentology, structural geology and geomechanics, and seismic petrophysics.
  • How to determine elastic properties from AVO/AVA analysis for fluid and lithologic discrimination.
  • How to integrate well data through seismic inversion techniques.
  • The role of seismic attribute analysis and related techniques in understanding risk elements from exploration, drilling and completion, and development stages.
