Honoring uncertainties - a deep dive into the engine room of Multiple-Point Statistics

PhD defence, Tuesday 28th of June 2022. Óli Dagmann Jóhannsson.

Oli Dagmann Johannsson

During his PhD studies, Óli Dagmann Jóhannsson researched geostatistical methods, which have applications in a broad range of fields, from mineral prospecting to groundwater mapping etc.. A deep dive into the engine room of some of the modern methods, called Multiple-Point Statistics,has allowed developing a novel method to take into account the uncertainty of multiple data simultaneously, as well as a method to quickly estimate values based on geological knowledge while conditioned to data.

When uncertainties are correctly taken into account, risk of erroneous conclusions can be minimized, and this work contributes to that.

The PhD study was completed at Department of Geoscience, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
