Computational Geophysics (Fall Term) - MFI81206
2 credits
Instructor: Dr. Abd Haris
Teaching Assistant: Befriko Murdianto
Pre-requisite: Mathematical Methods in Geophysics - MFI81200
The objective of this course is to provide students with
knowledge of advanced algorithms that can be utilized in solving
geological/geophysical problems, especially related to subsurface modeling and
imaging problems. This course requires students to have basic knowledge of
vector analyses and vector/matrix programming such as Matlab. This course will
use much of the function files provided in the CREWES Matlab Toolbox available
at http://www.crewes.org/Samples/EduSoftware/ReleaseAgreement.html
Syllabus:
- Raytracing
in V(z) media: Snell’s Law, Fermat principle, ray parameter, solving root
of equation using bisection method and Matlab’s fzero function.
- Acoustic
wave finite difference (FD) modeling: 2-D scalar wave equation, FD
modeling with the acoustic wave equation, acoustic wave FD implemented in
Matlab.
- Poststack
time and depth migration/imaging: exploding reflectors, introduction to
one-way propagators, f-k migration, poststack time and depth migration
implemented in Matlab.
