Provides consultancy on field development planning, technology strategies and IOR/EOR methodologies. He focuses on understanding the physics and chemistry of the recovery mechanisms and from this understanding being able to select the best recovery process, given operating conditions, risks and life cycle opportunities.
Conducted, supervised and coordinated many full field (re)development studies, mainly for Shell, but also for other companies. This included developing models, either analytical or simulation based, for the whole production stream from reservoir to pipeline, for oil and gas fields.
Over 40 years experience, mainly working for Shell. Focuses on research on SCAL techniques, with numerous peer-reviewed papers, and on teaching SCAL, EOR, geothermal. Interpretation-by-simulation of laboratory data has been the continuous factor in his career. Developed the SCAL simulator SCORES on jgmaas.com.
Ad has over 40 years of experience in exploration and production, including a long career with Shell in technical, commercial, and managerial roles worldwide. Trained as a production technologist and petroleum engineer, he has held senior positions in well, reservoir, and asset management. Since 2016, he has worked as a consultant on geothermal, hydrocarbon, and CO₂ storage projects, including offshore field evaluations and CCS development.
Wim is a geoscience advisor, asset and project manager, and mentor with over 35 years of international experience. As Director of KOIGEOS Ltd, he provides geoscience, asset management, and staff development services across hydrocarbons, CCS, and geothermal projects. His expertise spans geological and geophysical interpretation, petroleum systems analysis, asset management, and delivery of multidisciplinary seismic and drilling projects worldwide.
Mia Van Steenwinkel is a senior petroleum geologist and leadership trainer with over 35 years of E&P experience at Shell, PDO, and as an independent.

Arie is a senior geoscientist with extensive experience in regional subsurface geology and hydrocarbon play evaluation. After an early academic career, he spent nearly three decades with Shell in senior exploration, advisory, and learning roles. Since 2010, he has supported multiple energy companies through exploration studies, staff development, and management assignments, and continues to lead and develop integrated geological field studies.
Researcher with 30+ years of experience, specialised in the interpretation of NMR core and log data. Experienced in other Petrophysics subjects, ranging from research into tool physics to development of new petrophysical applications: e.g. log deconvolution, thin bed analysis, core analysis, sponge coring, EOR trials.
All-round petrophysicist and wellbore geomechanicist with extensive hands-on experience in international oil and gas projects (Netherlands, Oman, Norway, Russia, Canada), and more recently in Dutch geothermal developments. Experienced in clastic, carbonate and unconventional reservoirs, covering exploration through production monitoring. Also involved in unitisation studies. Founded his independent consultancy in 2019.
Ap is a senior petrophysicist with a long career at Shell, where he worked in operational, field development, quality assurance, and discipline improvement roles across Europe and the Middle East, with global project exposure. His expertise covers core petrophysics, integrated reservoir modelling, uncertainty analysis, and saturation modelling. Since 2015, he has worked as an independent consultant, delivering pragmatic, value-driven solutions and mentoring professionals.
Herman is a senior geophysicist with nearly 38 years of experience in seismic processing at Shell, combining hands-on technical roles with senior management positions.
