Mechanical and Hydraulic Aspects of Rock-Proppant Systems : Laboratory Experiments and Modelling Approaches

Andreas Reinicke
[...] In context of this work, a new damage mechanism is proposed: the mechanically inducedfracture face skin. This new mechanism results from mechanical interactions between the proppants and the reservoir rock, due to the increasing stress on the rock-proppant system during production. Proppant embedment into the fracture face and proppant crushing leads to fines production and can impair the fracture performance. In order to achieve sustainable, longterm productivity from a reservoir, it is indispensable to...

Geo-Energie: Konventionelle und unkonventionelle fossile Ressourcen

Brian Horsfield, Rolando Di Primio & Hans-Martin Schulz
Despite the upcoming shift in energy sources towards the environmentally friendly and renewable, conventional oil and gas resources should not be neglected. Fossil fuels are the current main energy source worldwide, accounting for over 75 % of the total energy budget. Though considerable investments in renewable energy have been made in recent years the dominance of fossil fuels will remain for many years to come. The long-term availability of fossil fuels depends on both effective...

Geologische CO2-Speicherung am Pilotstandort in Ketzin - sicher und verlässlich

Michael Kuehn, Thomas Kempka, Axel Liebscher, Stefan Lueth, Sonja Martens & Cornelia Schmidt-Hattenberger
In the context of climate policy, the storage of carbon dioxide (CO2 ) in deep geological formations is seen as a potential means to reduce anthropogenic greenhouse gas emissions and mitigate respective global warming effects. However, residents living near possible storage sites are concerned about this technology: Is it feasible to store CO2 safely and on the long term without endangering humans or the environment? Science and technology can provide answers to this question. In...
