Rock physics models for fluid and stress dependency in reservoir rocks are essential for quantification and interpretation of 4D seismic signatures during reservoir depletion and injection. However, our ability to predict the sensitivity to pressure from first principles is poor. The current state-of-the-art requires that we calibrate the pressure dependence of velocity with core measurements. A major challenge is the fact that consolidated rocks often break up during coring, and hence the stress sensitivity is likely to be overpredicted in the laboratory relative to the in-situ conditions (Furre et al., 2009). For unconsolidated sands, acquisition of core samples is not very feasible due to the friable nature of the sediments. One physical model that has been applied to predict pressure sensitivity in unconsolidated granular media is the Hertz-Mindlin contact theory. Several authors (Vernik and Hamman, 2009, among others) have suggested empirical models with fitting parameters that correlate with microcrack intensity, soft porosity, and aspect ratio of the rock, and feasibility studies can be undertaken based on assumptions about these parameters. These models may not be easy to use for poorly to moderately consolidated sandstones with contact cement, where crack parameters and aspect ratios are difficult to quantify. © 2011 Society of Exploration Geophysicists.

European manufacturing industry faces increasing product variances resulting as a consequence of frequent innovation, short product lifecycles, small series production, and shrinking production cycles. At the same time, production cost must be continuously reduced. Agile, transformable and re-usable automation and robotics is be a key enabler to manage those trends. However, few robotic components are designed for easy adaptation and reuse. To overcome those shortcomings, R5-COP focuses on agile manufacturing paradigms and specifically on modular robotic systems. Based on existing and newly developed methods for a formal modeling of hardware and software components, R5-COP will support model-based design, engineering, validation, and fast commissioning. Furthermore, using existing interface and middleware standards such as ROS, R5-COP will strongly facilitate integration of components from various suppliers. The proposed modular approach will not only be more flexible than state-of-the-art solutions, but will also reduce design, setup, and maintenance costs. Flexible use of robots naturally includes their close cooperation with humans. Therefore, robustness and safety are crucial requirements which will be assured by dedicated verification and validation methodologies. The formal specification framework will support component suppliers in efficiently verifying and certifying their modules. R5-COP will help to identify and develop reconfigurable key hardware and software components, and to show the feasibility and capability of the approach in living labs in manufacturing and service demonstrator environments.

In order to unlock the full potential of Europes offshore resources, network infrastructure is urgently required, linking off-shore wind parks and on-shore grids in different countries. HVDC technology is envisaged but the deployment of meshed HVDC offshore grids is currently hindered by the high cost of converter technology, lack of experience with protection systems and fault clearance components and immature international regulations and financial instruments. PROMOTioN will overcome these barriers by development and demonstration of three key technologies, a regulatory and financial framework and an offshore grid deployment plan for 2020 and beyond. A first key technology is presented by Diode Rectifier offshore converter. This concept is ground breaking as it challenges the need for complex, bulky and expensive converters, reducing significantly investment and maintenance cost and increasing availability. A fully rated compact diode rectifier converter will be connected to an existing wind farm. The second key technology is an HVDC grid protection system which will be developed and demonstrated utilising multi-vendor methods within the full scale Multi-Terminal Test Environment. The multi-vendor approach will allow DC grid protection to become a plug-and-play solution. The third technology pathway will first time demonstrate performance of existing HVDC circuit breaker prototypes to provide confidence and demonstrate technology readiness of this crucial network component. The additional pathway will develop the international regulatory and financial framework, essential for funding, deployment and operation of meshed offshore HVDC grids. With 35 partners PROMOTioN is ambitious in its scope and advances crucial HVDC grid technologies from medium to high TRL. Consortium includes all major HVDC and wind turbine manufacturers, TSOs linked to the North Sea, offshore wind developers, leading academia and consulting companies.

New concepts for high-temperature geothermal well technologies are strongly needed to accelerate the development of geothermal resources for power generation in Europe and worldwide in a cost effective and environmentally friendly way. The GeoWell project will address the major bottlenecks like high investment and maintenance costs by developing innovative materials and designs that are superior to the state of the art concepts. The lifetime of a well often determines the economic viability of a geothermal project. Therefore, keeping the geothermal system in operation for several decades is key to the economic success. The objective of GeoWell is to develop reliable, cost effective and environmentally safe well completion and monitoring technologies. This includes: - Reducing down time by optimised well design involving corrosion resistant materials. - Optimisation of cementing procedures that require less time for curing. - Compensate thermal strains between the casing and the well. - Provide a comprehensive database with selective ranking of materials to prevent corrosion, based on environmental conditions for liners, casings and wellhead equipment, up to very high temperatures. - To develop methods to increase the lifetime of the well by analysing the wellbore integrity using novel distributed fiber optic monitoring techniques. - To develop advanced risk analysis tools and risk management procedures for geothermal wells. The proposed work will significantly enhance the current technology position of constructing and operating a geothermal well. GeoWell aims to put Europe in the lead regarding development of deep geothermal energy. The consortium behind GeoWell constitutes a combination of experienced geothermal developers, leading academic institutions, major oil&gas research institutions and an SME. These have access to world-class research facilities including test wells for validation of innovative technologies and laboratories for material testing.

Rhizocorallium is one of the oldest known trace fossils, with wide distribution through the Phanerozoic and all over the world. Originally introduced from the epicontinental Triassic of central Germany, its high morphological lability gave reason for the subsequent erection of about twenty ichnospecies. The study of newly collected material from the type area and many specimens from various collections permits the conclusion that Rhizocorallium jenense and Rhizocorallium commune are the only valid ichnospecies of Rhizocorallium. The type ichnospecies, R. jenense, is a comparatively small, inclined and heavily scratched firmground burrow with passive fill, while R. commune consists of extensive, more or less horizontal burrows with occasionally scratched marginal tubes and an actively filled spreite between the tubes. The faecal pellets Coprulus oblongus are typically associated with R. commune. Morphological variations of R. commune are captured in ichnosubspecies and varieties of this ichnospecies and can aid a refined reconstruction of palaeoenvironments. A review of more than 180 records from the literature reveals the common confusion of both ichnospecies, which has consequences for the application of Rhizocorallium in facies interpretations. The end members of both ichnospecies may be linked by transitional forms, which suggests the same kind of trace maker. Polychaetes are the most likely producers of marine Rhizocorallium, based on their long-ranging occurrence, morphological features, appearance of faecal pellets, associated soft-body remains, and modern analogues. R. commune occurs from Early Cambrian to Holocene, while R. jenense just appears after the end-Permian mass extinction, probably as a consequence of an adapted firmground burrowing lifestyle of its producer. Fluvial R. jenense are probably produced by mayfly larvae in homology to marine polychaete burrows. A consequent application of the newly established classification scheme allows for a more rigorous application of Rhizocorallium in the reconstruction of palaeoenvironments. Thus, Palaeozoic and Mesozoic R. commune are restricted to the Cruziana ichnofacies of shallow-marine environments, while in Cenozoic time similar forms are also found in deep-marine deposits. R. jenense, on the other hand, is a constituent of the widespread Glossifungites ichnofacies and, aside from continental environments, occurs in peritidal to deep-marine deposits. Several studies have demonstrated the value of Rhizocorallium for interpreting sequence-stratigraphical surfaces, current directions, and fluctuations in salinity and oxygen. © 2013 Elsevier B.V.
