Basic Geophysics

Duration: 5 days

Business context

Geophysics provides the tools with which we can "look" into the subsurface. It is a key enabler of many E&P activities and decisions. This course is designed to provide an introduction to geophysics as it is applied for  exploration and development purposes in the industry. It provides an understanding in the fundamentals of potential field methods and reflection seismology, with strong emphasis on the latter. Modern seismic acquisition and processing techniques will be discussed and interpretation will be taught using a large number of examples and hands-on paper interpretation.

Who should attend

Geologists, geophysicists, and petroleum engineers, involved in exploration and development of oil and gas fields.

Course content

  • Potential field methods, gravity and magnetics.
  • Basics of surveying.
  • Fundamentals of signal theory and wave propagation.
  • Seismic acquisition, land and marine. Essentials of processing.
  • Principles of structural and stratigraphic interpretation.
  • 3D seismic.
  • Time-to-depth conversion.
  • Well Geophysics and synthetics.
  • Principles of quantitative analysis of seismic data.
  • Direct Hydrocarbon Indicators.
  • Artefacts.
  • New developments

Learning, methods and tools

At the end of the course, participants will have a good understanding of the fundamental concepts in geophysical exploration. With that foundation they will be able to better grasp the potential of seismic data in terms of interpretation value and liaise and collaborate with experts in the fields of seismic acquisition, processing and interpretation. Other benefits include:

  • To place and value geophysical activities in a multi-disciplinary context
  • Judge the merits of various geophysical techniques
  • Better liaise and collaborate with staff in related Geoscience and Petroleum Engineering disciplines
  • Recognise artefacts and direct hydrocarbon indications on seismic
  • Value novel developments such as time lapse seismic for exploration/petroleum development purposes

The course uses a mixture of lectures and practical exercises. The course can be customised to meet specific needs of participants. A 3 day version "Geophysics for other disciplines" can also be provided.
