Exploration Geophysics Applied to the Oil & Gas Industry

Exploration Geophysics Applied to the Oil & Gas Industry

Geophysics involves the use of physical techniques to study the earth's interior. It comprises of a range of disciplines, including seismic, gravity, magnetic and geo-electrical methods.

Exploration Geophysics is key to understanding the resource potential of the subsurface – whether it’s water, minerals, geothermal heat or hydrocarbon reserves. It is applied in engineering site investigations and environmental assessments.

The course provides the participant with a breadth of practical skills, underpinned by a theoretical understanding that allows the participant to become a professional in their chosen field.

The course starts with an overview of geophysical methods, then delves deeper into the methods used for oil and gas exploration. The course then moves on to cover wave propagation, followed by the Seismic Reflection Theory and its application in acquisition.

The course also covers data digitalization, sampling and how to avoid aliasing in the recorded data and during resampling in order to ensure optimum data quality. Seismic data acquisition parameters will be covered with practical examples and exercises in order to improve the participants’ skills in selecting the acquisition and processing parameters. This will be followed by an overview of the best practices and the most recent seismic 2D and 3D data acquisition techniques used onshore and offshore. The participants will then learn the theoretical biases of the most important terms of seismic processing: the Fourier transform, time and frequency domain, convolution, cross and auto-correlations. The participants will then learn how to build an optimum processing sequence in order to study the interpretation techniques, to see faults, reflections and diffractions, and to do contour maps parameters in their own operations and in different environments using the latest techniques.
