After graduation, Karl-Heinz Wolf worked from 1983 for two years on different assignments, varying from field exploration in Scandinavia, through banking, to geo-engineering activities. In 1985, when following post-academic courses in Reservoir-Engineering at Delft University, he joined the Faculty of Mining and Petroleum Engineering. He started as research assistant in Petroleum Geology (till 1988), followed by Petroleum Engineering (till 1996) and continued as Associate Professor in Applied Geophysics and Petrophysics. From 2011 on he is head of the Geoscience and Engineering Laboratories. This department section has 14 technicians supporting research, field work and educational projects in geology, geophysics, reservoir engineering and geo-engineering.
This career was encouraged by his continuous development of multi-disciplinary societal relevant research programs and projects. Through his career he improved and used petrophysical techniques to develop rock texture characterisation and quantification for reservoir engineering and rock mechanics programs. He works on the interfaces between geology, reservoir engineering and geophysics. It started with themes regarding clean coal technology, such as in-situ coal combustion, natural coal fires, In-situ oil (shale) combustion and CO2 enhanced coalbed methane production. After ten years environmental research was included through carbon-dioxide storage with an extension to the additional benefits of CO2-EOR/EGR. The expertise he obtained was transferred to gas shale, oil shale and carbonate-acid research in the past ten years. All activities have been associated to large experimental set-ups for scaled tests. Realizing two decades ago that image analysis is an essential tool for rock and pore texture characterisation, he started an image laboratory, which now includes all services needed to quantify images from outcrop scale to micro-CTS scale.
