Stratigraphic Analysis of 3D Seismic Data

Discipline:       Geology/Geophysics

Level:             Intermediate to Advanced

Instructor:       Dr. Erik Scott

Length:           3 Days

 

Who Should Attend

Geologists and geophysicists who use seismic data for petroleum exploration and/or production.

 

YOU WILL LEARN HOW TO

  • Prepare the 3D seismic volume for interpretation
  • Determine what reflectors are geologically significant and how to create a surface along them
  • Use attributes and volume visualization/opacity to image elements of depositional systems through time
  • Identify potential hydrocarbon indicators and fluid movement features

 

ABOUT THE COURSE

This course will cover how to image and interpret depositional systems in 3D seismic data and build a stratigraphic framework.  We will cover workflows to isolate and visualize sedimentary architecture to reconstruct elements from a variety of depositional environments. Through various techniques we will develop basin to prospect scale stratigraphic histories and discuss implications for petroleum systems.  Participants will gain an understanding of the expression of different depositional settings on seismic data and the methods for evaluating them. Experience interpreting seismic data and an understanding of deposit geometries from a variety of sedimentary environments are desirable for this course.

Seismic interpretation platform – The concepts and methods covered are software independent.  This default software for this class is Petrel.  A dataset will be provide for the class, however participants are encouraged to bring in their own Petrel project and seismic data to work on in class.  If desired, a participant can also work with their software of choice (e.g. Geoprobe, VoxelGeo, GeoViz) along with a seismic data set by bringing in a workstation laptop with the software or remotely connecting.
