Book Cover

Introduction to Petroleum Seismology.  Investigations in Geophysics Vol 12 by Ikelle and Amundsen, 2005. First Edition

Goals:

Fundamentals of mathematical physics, seismology and signal theory used to understand geological processes and structure in the earth.

Course work

One homework every 2-3 weeks, readings from the research literature and one final group project (groups of 2+ people)

Lectures will include but not be limited to topics covered by the course textbook. 

Each group will make a preliminary (15-minute) presentation of their final project in the format of a PowerPoint Presentation.

The final project will consist of an electronic document that is hyperlinked,  self-contained presentation of a seismology topic, with appropriate mathematical derivations, examples, plots and source code, on Wikipedia.  Students can choose topics covered in class and develop them to greater depth than covered in the text book.  Students will be evaluated on their course project at the midterm stage.  Student groups will be expected to present their final project orally.

All homeworks, with the exception of the final project, are due printed (not hand-written), at the start of the class on the due date (see syllabus).   There will be 4-5 homework assignments. Late homeworks will not be graded.

For each hour you are in class, you (the student) should plan to spend two hours on preparing for the next class and completing homework and laboratory work. 

Expected courses and experience Two semesters of undergraduate science major mathematics--Algebra and Calculus.  Physics with Calculus, programming experience with at least one high-level language like Excel, Matlab or Maple or Mathematica
 

Course Grades

Final letter grades are calculated using the results of lecture homework (50%) and class presentations (10%), and final written project (30%) -- 10% of the total grade is reserved for class participation during project presentations and discussions.  A (90-100%) , B (80-89.5%), C (60-79.5%) D (50-59.5%), F (less than 49.5%)
