- Remote sensing techniques, principles, classification, sensors, thermal infrared, microwave, radiowave & microwave, visible & UV, radiometric techniques.

Study-unit Aims:

The study-unit aims to provide the student knowledge of the physical properties of minerals and rocks and how these properties influence geophysical fields such as gravity, magnetic, and electrical fields that can be measured and used to to explore the subsurface for geological structural and stratigraphic features that can hold petroleum accumulations.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to Understand the:
- Principles of non-seismic geophysical investigations and the relationships between the various techniques;
- Application of each techniques (excluding seismic) covering data acquisition, instrumentation, processing and analysis of data.

2. Skills:

By the end of the study-unit the student will be able to:
- Conceive and formulate a geophysical investigation in a variety of geological environments;
- Select the appropriate geophysical technique and procedure in a variety of situations;
- Research and synthesise geophysical information relevant to the investigation from a variety of sources;
- Plan and conduct the appropriate geophysical survey (excluding seismic) and interpret the data in terms of the surface and subsurface geology.
