Nick obtained his BEng degree in Mining & Metallurgical Engineering at the National Technical University of Athens in 2017. His thesis, utilising a set of analytical techniques, debated the (at that time) current deposit classification of a pyrite ore deposit, leading to a conference paper (1st CAJG). He then obtained a full scholarship from Hellenic Petroleum S.A. to attend the Petroleum Exploration & Engineering postgraduate course at the Technical University of Crete in 2018, from which he graduated with a 1st class degree. He conducted his postgraduate thesis and then remained as an intern at the National Centre for Scientific Research “Demokritos” – Institute of Nuclear and Particle Physics. His project involved the numerical analysis of partitioning inter-well tracing testing aimed at establishing remaining fluid saturations prior to Enhanced Oil Recovery applications. Thereupon, Nikolaos was employed as a Junior Field Engineer, at the coal mine area of Kozani-Ptolemais (Public Power Corporation of Greece) in the light-equipment front opening section.
Afterwards, he attended the Petroleum Engineering MSc course at the University of Aberdeen, graduating with a 1st class degree in 2020. His MSc thesis (compositional numerical modelling) focused on the effects of molecular diffusion, gas type, and matrix permeability on cyclic huff n’ puff gas injection of unconventional reservoirs, thereby attempting to fine tune the various cycles’ durations, as well as to delineate the recovery mechanisms being involved. He also investigated the numerical efficiency of existing foam models in continuous foam injection in tight oil reservoirs. After his graduation he joined the Hellenic Army serving as an act. Staff Sgt in engineering units related to fuel supply. Right after his decommissioning, and prior to commencing his PhD studies, Nikolaos collaborated with researchers from the University of Aberdeen and the Institute of Geo-Energy in Greece (IG/FORTH) on a project concerning the hydrocarbon and storage potential of the Forth Approaches Basin in Scotland. The early results of this study reflected positive results for the potential of this underexplored basin (82nd EAGE annual conference)..
