Aspects of material transport and polycrystal growth in fractures
The thesis investigates fracture sealing processes from micro- to basin scale. Chapter 2 describes the microstructural evolution of fracture sealing using a self-designed see-through apparatus. Analogue material is used to visualize and model sealing processes on a microscale, which is quantified …

Degradable nanocomposite preformed particle gel for chemical enhanced oil recovery applications
… is an elastomeric rubber gel as a potential fracture-sealing agent. An elastomeric rubber gel has been synthesized from degraded preformed particle gel crosslinked with Poly (ethylene glycol) diacrylate and bentonite clay. Elastomeric rubber gel formed using 0.5% degraded preformed particle …

The effect of testing conditions on lost circulation materials' performance in simulated fractures
… the difficulties of testing and monitoring LCM sealing processes in the field, LCM evaluation in the laboratory is often used to prove and assure successful treatment. Investigating LCM behavior and the causation of obtaining different results would expand the reliability of the laboratory …

Rb-Sr Alter und Sr-Pb Isotopencharakteristik von Gangmineralisationen in paläozoischen Gesteinen am Nordrand des linksrheinischen Schiefergebirges (Raum Stolberg-Aachen-Kelmis) und Vergleich mit den rezenten Thermalwässern von Aachen-Burtscheid
… flow. The brecciated zone 1 marks the first fracture sealing process. It contains fragments of galena crystals, chalcopyrite, bornite, quartz, dolomite, ankerite and blocks of the wall rocks fixed in a calcitic matrix. The second fracture sealing phase (zone 2) is composed exclusively of …
