Module summary

In this module students will learn the theory and practice of gravity, magnetic and EM methods as applied to petroleum exploration.


To understand the application of gravity, magnetic and EM methods to petroleum exploration; to understand the procedures of gravity, magnetic and EM data acquisition and processing, such that they can take part in operations or review the work of others; to apply processing and interpretation tools to derive geological information from gravity and magnetic data sets.

Learning outcomes
On completion of this module, students should have acquired an understanding of the practical uses of gravity, magnetic and EM surveys and how they fit into the general petroleum exploration process. They should be able to:

- Contribute to discussion and planning of surveys, considering both theoretical and practical factors
- Plan and execute the processing of gravity and magnetic data
- Perform geological interpretation of gravity and magnetic data together with other information
- Evaluate their own work and the work of others

The learning outcomes will be assessed using a short data-processing report and an independent written report.


The role of gravity, magnetic and EM methods in hydrocarbon exploration; causes of gravity and magnetic anomalies; gravity and magnetic data acquisition (land, marine, airborne, space); gravity and magnetic data reduction; gridding and levelling of gravity and magnetic data; data enhancement processing and lineament mapping; magnetic depth estimation; gravity and magnetic data modelling and inversion; integrated interpretation incorporating gravity and magnetic data; principles of EM Theory; MT, CSEM, MTEM methodology and application.

The re-sit for this module takes the form of an open book exam; the student will have 24 hours to produce their answer to an exam paper. The paper will be of similar length to a standard 2 hour exam. The re-sit mark provides a new alternative mark for the whole Module.
