    Land Seismic Acquisition Techniques and Survey Design

    The course is designed to familiarize the student with the basics of 3D Land seismic acquisition before moving on to cover the more recent developments: high channel-count single sensor (point receiver) simultaneous source – high productivity vibroseis, broadband techniques (boosting the low and high freqencies) and wireless nodal systems. Learning is supported through numerous case histories that illustrate the value of each acquisition technique. Central to the success of these techniques is how the surveys are designed to deliver fit-for-purpose data in a cost-effective manner.

    In the second half of the course the students are taken through the principles of survey design. Learning is supported via hands-on practice where participants work together to design solutions to typical survey objectives and challenges.

    At the end of the course, students will be familiar with: all current and emerging land seismic acquisition technology and techniques; the principles and workflows employed to design land seismic surveys; how to make a “first-pass” assessment of whether a proposed survey design will be successful and economic; and how and what to recommend as further areas of investigation if required.

    Geophysicists with limited experience of seismic acquisition, or more experienced staff including Interpreters and Operational Geophysicists who need to keep up with the rapidly developing field of modern seismic acquisition techniques.
