Jaap Mondt

Geophysical Consultants


Jaap Mondt (1947) obtained his Bachelors in Geology at the State University of Leiden after which he went to Utrecht to study Theoretical Geophysics. His PhD dealt with the determination of the Core-Mantle transition analyzing P and S waves diffracted around the liquid outer core.

Following his PhD in Utrecht on “Full wave theory and the structure of the lower mantle”, he joined Shell in The Hague to work on the prediction of lithology and pore-fluid based on seismic, petro-physical and geological input. During his subsequent 3-year stay with Shell Expro in London he interpreted seismic data from the Central North Sea area. He was also actively involved in seismic experiments from drilling rigs and production platforms.

Subsequently he joined Shell Rijswijk in 1977 to do research in Quantitative Interpretation based on seismic, petro-physical and geological data. After a posting in London where he worked on the interpretation of data of the North Sea Central Graben, he returned to Rijswijk to head a Quantitative Interpretation Team, developing 3D Interpretation Workstation methods. This was followed by an assignment to supervise Contractor Seismic Processing: software as well as actual projects. The next job was Course Director Geophysics in the Shell Learning Centre. At the same time he was for 5 years part-time Professor in Applied Geophysics at the University Utrecht in The Netherlands. After 4 years he went back to Rijswijk to work on applying Potential Field methods (Gravity, Magnetics and Electro-Magnetics).



From 2001 until 2005 he worked on the use of Potential Field Methods (Gravity, Magnetic fields) for detecting oil and gas, later extended with the use of electromagnetic fields. Finally, until his retirement he worked in Research on Electromagnetic methods (Controlled Source EM and Magneto-Telluric). After retiring from Shell he founded his own company (Breakaway), providing courses and advice on the acquisition and processing of geophysical data (seismic, gravity, magnetic and electromagnetic data. Currently he gives many courses at Universities as well as international and national energy companies.
