Optional Textbook:
 Applied Subsurface Geological Mapping with Structural Methods, 2nd edition, 2003,
  Prentice-Hall, by D. J. Tearpock & R. E. Bischke
 Additional reserve materials will be supplied and kept in the conference room or the
  computer lab.

Goals of this course:
 To provide an introduction to the datasets, tools & methods used in mapping subsurface
   geology
 To use subsurface data to understand the evolution of structures and depositional systems in
   time and 3D space
 To obtain some “hands-on” experience with workstation-based 2D and 3D seismic
   interpretation

Learning outcomes:
 Given a set of geophysical well logs, the student should be able to construct a correlation
   panel
 Student should be able to map horizons and faults in a grid of 2d seismic reflection data or 3d
   seismic volume, using appropriate computer software
 Student should be able to convert seismic reflection data from two-way travel time to depth,
   given information on velocity
 Students should be able to interpret the history of a sedimentary basin from subsurface data

Course format:
A mix of lecture, seminar-style discussion and lab exercises; workstations will be utilized in
nearly every class session, so the lectures will be brief.

Course grading:
 Exercises/problem sets 33.33%
 "Take-home" Midterm Exam 33.33% (during week 10 of the semester)
 Final project or term paper 33.33%
