Format: this course consists of video lectures, reading material, quizzes, a discussion forum and 4 live interactive webinars with the instructor. The live webinars will take place in the first two weeks of the course as indicated in the schedule below. During this time the instructor will be available for questions. After that, participants will have time to study independently, review the course materials and complete the assignments. The discussion forum will remain available for offline Q&A with the instructors during the entire duration of the course.

Note this is an estimation of the time required to go through the course, including watching/reading lectures, attending webinars and completing quizzes.
After purchasing this course, you will have access to the intake quiz and introductory course materials. All course materials and assignments will be available after the course starts. You will have access to the course for a total period of 1 month after the start of the course. Make sure to complete all the requirements for the achievement of the certificate by this date.
A certificate of completion will be available upon completion of all course requirements. After the end of the course, your certificate will remain available for download in your Profile page.
Brief course description
Non-Seismic methods such as gravity and magnetics provide valuable complementary information about the subsurface that is not provided by Seismic methods. In this course you will learn about these techniques and their use in the search for hydrocarbons, ores, salt-fresh water boundaries, etc.
Course outlinePart 1: Gravity
- Geophysical Methods
- Gravity Anomaly
- Depth Estimation
- Gravity Response
- Inversion of Gravity Data
- Gravity Resolution
Part 2: Magnetics
- Geo-Mag Signatures
- Magnetic Modelling
- Magnetic Anomaly
- Inversion of Magnetic Data
- Gravity and Magnetic Response
- Geomodel Inversion
Upon completion, participants will understand the use of gravity and magnetics data, how they are acquired, the benefits of employing them in geophysical acquisition projects and how to decide how much money to spend on a Non-Seismic Project.
The course assumes a reasonable understanding of Physics.

About the instructor
I obtained a Bachelors in Geology at the University of Leiden, a Masters in Theoretical Geophysics at the University of Utrecht and a PhD in Theoretical Geophysics at the University of Utrecht.
My PhD in Utrecht was on “Full wave theory and the structure of the lower mantle”. This involved forward modelling of Pand S-waves diffracted around the core-mantle boundary and comparison of the frequency-dependent attenuation of the signal with those obtained from major earthquakes observed at long offsets in the “shadow zone” of the core. These observations were then translated into rock properties of the D” transition zone. After my PhD I joined Shell Research in The Netherlands to develop methods to predict lithology and pore-fluid based on seismic, petrophysical and geological data. Subsequently I worked in Shell Expro in London to interpret seismic data from the Central North Sea Graben. As part of the Quantitative Interpretation assignment I was also actively involved in managing, processing and interpreting Offshore Well Seismic Profiling experiments (from drilling rigs and production platforms). After my return to The Netherlands I headed a team for the development of 3D interpretation methods using multi-attribute statistical and pattern recognition analysis on workstations. After a period of Quality Assurance of “Contractor” software for seismic processing, I became responsible for Geophysics in the Shell Learning Centre. During that time I was in addition part-time Professor in Applied Geophysics at the University of Utrecht. From 2001 till 2005 I worked on the development of Potential Field Methods (Gravity, Magnetics) for detecting oil and gas. Finally I became a champion on the use of EM methods and became involved in designing acquisition, processing and interpretation methods for Marine Controlled Source EM (CSEM) methods. After my retirement from Shell I founded my own company (Breakaway), specialised in courses on acquisition, processing and interpretation of geophysical data (seismic, gravity, magnetic and electromagnetic data). In addition to still providing support to the Shell Learning Centre I give my own courses to International as well as National energy.
