Geophysical Data Acquisition and Processing (Basic Geophysics)


Duration: 5 days

Introduction

Geophysics provides technology with which we can "look" into the subsurface. It is a key enabler of many activities in the search for hydrocarbons, minerals, and fresh water. It is also extensively used in the domain of monitoring pollution and rejuvenation of polluted sites. The course provides the fundamentals of seismic refraction & reflection methods, the use of gravity, magnetic, electrical, and electromagnetic methods. Modern geophysical acquisition and processing techniques will be taught not only based on a textbook but by applying the theory in mainly Excel based exercises

Who should attend?

Geologists, Geophysicists and Petroleum engineers, involved in exploration and development of oil and gas fields and for those involved in projects related to the shallow subsurface. In addition, it would be useful for those dealing with the (geo)physical effects of production of a field.

Learning methods and tools

The course uses a user-friendly Learning Management System, called Moodle. In Moodle different modules provide study material, videos, and exercises. Also, each part contains a quiz using “mentimeter” which is meant to reinforce the learning.

Requirements

A reasonable level of understanding of geology and geophysics.

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.
