Marine Electromagnetic Methods for Hydrocarbon Exploration
by Steven Constable and Kerry Key
Duration: Two days
Intended Audience: Intermediate level
Prerequisites (Knowledge/Experience/Education Required): The course is designed to be followed by anyone with a broad geoscience background and a basic familiarity with geological and geophysical terminology. Although not required, a familiarity with calculus, Fourier analysis, and vector algebra will be useful.
However, the rapid assimilation of what has in the past been largely an academic enterprise has resulted in a shortage of skilled professionals. While there is a general interest in using marine EM technology, there is an associated general lack of understanding within the exploration community about the techniques, how they work, and their strengths and limitations. This course provides a working understanding of this new technology.
The theory of controlled source EM and magnetotelluric propagation in the marine environment is introduced and illustrated with simple one-dimensional modeling. This leads to an explanation of 2D and 3D computational methods and issues of target size, discrimination, etc. Inversion methodology is presented. Finally, example data sets illustrate the principles and discussed with participants.
This course will be of interest to anyone wishing to use marine EM data in an exploration arena. This course is suitable for exploration managers and geoscientists who wish to commission surveys or exploit existing data, and to new recruits within the contractor industry. Academics wishing to include aspects of marine EM into their curricula will also find this course helpful.
