Dr Arnout is a renowned expert 3D static reservoir modeller with 30 years experience building models of carbonates, clastics and unconventionals (CBM). He has particular strengths in seismic constrained reservoir modelling and in uncertainty analysis and management. He has authored several papers on these topics published in scientific journals and/or at international conferences.

Besides his 3D geomodeller skills, Arnout is also fully versatile in seismic interpretation, seismic attribute analysis including AVO and rock physics analysis, depth conversion and mapping. He can also perform routine petrophysical analysis.

Dr Arnout has a sound academic background in structural geology and extensive experience in applied structural geology to renewable energy and oil and gas projects. He can work with industry-standard tools and techniques but he has also a suite of niche tools specifically tailored to faultseal and structural geology assessment in exploration settings with sparse data.

In recent years, Dr Arnout has built considerable knowledge and experience in assessing geothermal resource potential and screening of notional development concepts for geothermal exploitation - in particular "sedheat" (hot porous aquifers), EGS (Enhanced or Engineered Geothermal Systems also known as Hot Dry Rock) and Closed-Loop wells. Besides the capability to perform the required subsurface reservoir characterization (assessment of geothermal gradients, mapping of geothermal reservoirs and their properties, characterization of fracture networks, definition of applicable geothermal play-types), he also has developed a range of bespoke tools, for example to quantify geothermal resources, assess the thermal-yield potential of different well and completion configurations and estimate the anticipated time of cool-water breakthrough from injectors to producers. For EGS systems, he deploys industry-standard analytical methods to assess the likely range of thermal recovery efficiencies and thermal heat yield of EGS wells.

For closed-loop wells, Dr Arnout has fit-for-purpose tools to help identify the optimum tubing and insulation configuration (minimizing overall system friction-losses by balancing losses across annulus and tubing), to assess initial thermal yield and to assess the impact of near-wellbore cooling and mitigation options such as cyclic production.

Over the last few years there has been increasing interest into natural hydrogen occurrences and their potential as a source of low-cost hydrogen supply for the energy transition. Whilst most ongoing research is focused towards understanding potential sources of hydrogen in the subsurface, Dr Arnout’s interest is more towards the technical development potential of natural hydrogen. That is, for the finds reported to date and/or speculated about: 1) how much hydrogen might be recoverable; 2) at what rates could natural hydrogen be produced from such finds; and 3) what would a development encompass in terms of welltypes, well counts and spacing, fluids produced alongside hydrogen etc etc. Arnout gave keynote papers on the topic at several conferences (e.g., EAGE-GET 2024; 3rd ASEAN Green Hydrogen Conference, May 2025; Geological Society of London, July 2025). He conducted an online seminar via EnergyNews.biz on the topic of Natural Hydrogen Development Potential, accessible via this link, wrote a landmark paper on resource-assessment methodologies (https://doi.org/10.1016/j.ijhydene.2025.05.357) and upon invitation, joined the Hydrogen Science Coalition (https://h2sciencecoalition.com/). Arnout's research on this topic continues to progress.
