Study-unit Aims:

The study-unit aims to combine the knowledge of the seismic reflection technique, the field acquisition of seismic reflection data, and signal processing to develop an understanding of the practical use of this exploration technique in petroleum exploration.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to understand the:
- Principles of seismic reflection investigations including 3D;
- Theory and techniques of seismic exploration including data acquisition and instrumentation;
- Theory and application of time series analysis in general and seismic data processing in particular.

2. Skills:

By the end of the study-unit the student will be able to:
- Analyse time series and design basic signal processing filters such as band pass filters and least square inverse filters;
- Select and use seismic techniques and procedures in a variety of situations, both onshore and offshore;
- Research and synthesise seismic information from a variety of sources including sonic logs and velocity surveys;
- Plan a seismic reflection survey and monitor its execution;
- Plan a seismic data processing programme and monitor its execution.
