    Description / Table of Contents: This book is a useful guide for researchers in ecology and earth science interested in the use of accelerator mass spectrometry technology. The development of research in radiocarbon measurements offers an opportunity to address the human impact on global carbon cycling and climate change. Presenting radiocarbon theory, history, applications, and analytical techniques in one volume builds a broad outline of the field of radiocarbon and its emergent role in defining changes in the global carbon cycle and links to climate change. Each chapter presents both classic and cutting-edge studies from different disciplines involving radiocarbon and carbon cycling. The book also includes a chapter on the history and discovery of radiocarbon, and advances in radiocarbon measurement techniques and radiocarbon theory. Understanding human alteration of the global carbon cycle and the link between atmospheric carbon dioxide levels and climate remains one of the foremost environmental problems at the interface of ecology and earth system science. Many people are familiar with the terms ‘global warming’ and ‘climate change’, but fewer are able to articulate the science that support these hypotheses. This book addresses general questions such as: what is the link between the carbon cycle and climate change; what is the current evidence for the fate of carbon dioxide added by human activities to the atmosphere, and what has caused past changes in atmospheric carbon dioxide? How can the radiocarbon and stable isotopes of carbon combined with other tools be used for quantifying the human impact on the global carbon cycle?

    Description / Table of Contents: This book seeks to enhance the cultural dimension of sustainable development and particularly focuses on minor historic centers and their natural and rural landscapes. In a society becoming ever more globalized, without territorial restrictions in the production of goods and able to reproduce in China the goods and product characteristic of South American crafts (to mention just two extremes), the only element that can still be contextualized is heritage identity: the result of close integration between cultural assets, intangible assets and settled communities. Thus, heritage identity is one of the few elements, together with natural resources, which has the potential for economic development that is still firmly rooted in places and local populations.These towns are often the centerpiece of urban landscapes and geographical areas with original features, not always but often as individual places within networks of minor historical centers linked by shared history, traditions and/or natural elements (rivers, forests, river systems or other natural elements). They are outside the major tourist networks, even if now there is a budding interest in the touristic exploitation of these environments. So, they are the right places to pursue a sustainable and local development with a cultural perspective. This book is a product of the VIVA_EASTPART project (Valorisation and Improving of management of Small Historic Centres in the eastern PARTnership region), under the EU-funded “ENPI Eastern Partnership” program. It complements the more practically-focused work that is in production from this group, more focused on empirical approaches to the development of minor historic centers of the nations involved. Though the book has been influenced by this research and working experience, the authors are solely responsible for the content and opinions presented.

    Description / Table of Contents: This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.

    Description / Table of Contents: This book will take an evidence-based approach to current knowledge about biomolecules and their place in our lives, inviting readers to explore how we know what we know, and how current gaps in knowledge may influence the way we approach the information. Biomolecular science is increasingly important in our everyday life, influencing the choices we make about our diet, our health, and our wellness. Often, however, information about biomolecular science is presented as a list of immutable facts, discouraging critical thought. The book will introduce the basic tools of structural biology, supply real-life examples, and encourage critical thought about aspects of biology that are still not fully understood.

    In: Theory and applications of transport in porous media, Volume 27
    Description / Table of Contents: This book treats the mechanics of porous materials infiltrated with a fluid (poromechanics), focussing on its linear theory (poroelasticity). Porous materials from inanimate bodies such as sand, soil and rock, living bodies such as plant tissue, animal flesh, or man-made materials can look very different due to their different origins, but as readers will see, the underlying physical principles governing their mechanical behaviors can be the same, making this work relevant not only to engineers but also to scientists across other scientific disciplines. Readers will find discussions of physical phenomena including soil consolidation, land subsidence, slope stability, borehole failure, hydraulic fracturing, water wave and seabed interaction, earthquake aftershock, fluid injection induced seismicity and heat induced pore pressure spalling as well as discussions of seismoelectric and seismoelectromagnetic effects. The work also explores the biomechanics of cartilage, bone and blood vessels. Chapters present theory using an intuitive, phenomenological approach at the bulk continuum level, and a thermodynamics-based variational energy approach at the micromechanical level. The physical mechanisms covered extend from the quasi-static theory of poroelasticity to poroelastodynamics, poroviscoelasticity, porothermoelasticity, and porochemoelasticity. Closed form analytical solutions are derived in details. This book provides an excellent introduction to linear poroelasticity and is especially relevant to those involved in civil engineering, petroleum and reservoir engineering, rock mechanics, hydrology, geophysics, and biomechanics.

    Description / Table of Contents: This report examines the scientific basis for the use of remotely sensed data, particularly Normalized Difference Vegetation Index (NDVI), primarily for the assessment of land degradation at different scales and for a range of applications, including resilience of agro-ecosystems. Evidence is drawn from a wide range of investigations, primarily from the scientific peer-reviewed literature but also non-journal sources. The literature review has been corroborated by interviews with leading specialists in the field. The report reviews the use of NDVI for a range of themes related to land degradation, including land cover change, drought monitoring and early warning systems, desertification processes, greening trends, soil erosion and salinization, vegetation burning and recovery after fire, biodiversity loss, and soil carbon. This SpringerBrief also discusses the limits of the use of NDVI for land degradation assessment and potential for future directions of use. A substantial body of peer-reviewed research lends unequivocal support for the use of coarse-resolution time series of NDVI data for studying vegetation dynamics at global, continental and sub-continental levels. There is compelling evidence that these data are highly correlated with biophysically meaningful vegetation characteristics such as photosynthetic capacity and primary production that are closely related to land degradation and to agroecosystem resilience.

    Description / Table of Contents: PREFACE During the so-called Mid-Cretaceous interval, approximately 100 million years ago, the earth experienced a dynamic phase in its geologic history. Enhanced global tectonic activity resulted in a major rearrangment of the continental plates; accelerated spreading rates induced a first-order sea level highstand; intense off-ridge volcanism contributed to a modeled high atmospheric CO 2 rate; climatic conditions fluctuated; and major changes occurred in biologic evolutionary patterns. With the initiation of a gradual change from an equatorial, east-west directed current-circulation pattern to a regime, dominated by south-north and north-south directed current systems, the earth's internal clock was set for Cenozoic, "modern" times. The Mid-Cretaceous dynamic phase is recorded in a suite of sediments of remarkable similarity around the globe. Shallow-water carbonate platforms drowned on a global scale; widespread sediment-starved, glauconite and phosphate- rich sequences developed; and consequently, pelagic sedimentary regimes "invaded" shelf and epicontinental sea areas. This typical "deepening-upward" pattern is well-documented in Mid-Cretaceous sequences along the northern Tethys margin. Shallow-water carbonates are overlain by condensed glauconitic and phosphatic sediments, which, in turn, are blanketed by pelagic carbonates. In this volume, the example of the western Austrian helvetic Alps, built up of inner and outer shelf sediments deposited along the northern Tethys margin, is used to elucidate the paleoceanographic conditions, under which the Mid-Cretaceous triad of platform carbonates, condensed phosphatic and glauconitic sediments, and pelagic carbonates was formed. In the first part, the evolution of this sequence is traced from the demise of the platform (Aptian) to the return of detritus-dominated deposition (Upper Santonian). The second part includes a discussion of the reconstructed paleoceanographic and tectonic variables, their possible interaction, as well as their influence on sediment properties during this period. Special attention is paid to (1) subsidence behavior of the inner, platform-based shelf and the outer shelf beyond the platform, (2) ammonoid paleobiogeography, (3) the northern tethyan current system and its impact on sediment patterns, (4) the influence of an oxygen minimum zone, (5) sediment bypassing mechanisms on the inner shelf, (6) condensation processes, (7) phosphogenesis, (8) relative sea level changes, (9) genesis and the development of unconformities, (10) tectonic phases and their impact on sediment configuration, (11) drowning of the shallow-water carbonate platform, and (12) "asymmetric" sedimentary cycles. The detailed reconstruction of the development of sedimentary patterns both in time and space in this particular area, and its environmental interpretation, given in this volume, may serve as a contribution to a better understanding of the Mid-Cretaceous dynamic phase in earth's history...

    Description / Table of Contents: INTRODUCTION Over the past 18 years the author and several colleagues have developed a mathematical model designed to predict the propagation characteristics of acoustic waves in marine sediments. The model is based on the classical work of Maurice Biot who developed a comprehensive theory for the mechanics of porous, deformable media in a series of papers spanning the time period from 1941 to 1973. Since our objective was to develop a practical working model that could be used as a guide in planning and interpreting experimental work, we began with the simplest possible form of the model and added various complexities only as they were needed to explain new variations in the data that were obtained. Thus the number of material parameters that had to be measured or assumed at any stage in the development of the model was kept to a minimum. Since the first version of the model was introduced in 1970, we have published over twenty technical papers covering various stages of its development and many papers have been published by colleagues who have utilized our work in various ways. This monograph is an attempt to summarize the development and use of the model to date. Acoustic waves in ocean sediments may be considered as a limiting case in the more general category of mechanical waves that can propagate in fluid-saturated porous media. The general problem of wave motion in this kind of material has been studied extensively over the past thirty years by engineers, geophysicists and acousticians for a variety of reasons. In some cases, interest is focused on low-frequency waves of rather large amplitude, such as those that arise near the source of an earthquake or near a building housing heavy, vibrating machinery. At other times, the main interest is in waves of low frequency and amplitude that have traversed long distances through the sediment. In still another category, high-frequency waves that are able to resolve thin layering and other fine structural details are of interest in studying near-bottom sediments. Thus the full spread of frequency and amplitude has been studied for geological materials ranging from soft, unconsolidated sediments to rock. Because of the almost limitless combinations of different types of sediment, stratification and structure, accurate mathematical description of the wave field produced by a particular source can be constructed only if accurate descriptions of the acoustic properties of individual components can be specified. These properties depend on the geological history of the sediment deposit, on the frequency content of the wave field and on a number of other factors that depend on the environment in situ. A survey of the literature suggests that there are a number of parameters that play principal roles in controlling the dynamic response of saturated sediments...

    Description / Table of Contents: INTRODUCTION The evaporite deposits of the Werra district, especially in the Hattorf mining field, are considered a worldwide unique location for the occurence of numerous basalt dikes and magmatic fluid phases fixed in salt rocks. In spite of the great number of studies dealing with the magmatites in the Werra region, previous investigations have rarely attempted more than a predominantly 'qualitative' description of the basaltic rocks and the effects of volcanism on the evaporites (see Chapter 2). The method of interpreting the mineralogical and chemical composition of the evaporites at the basalt contact is based on previous works (KNIPPING 1984; KNIPPING & HERRMANN 1985). This study should contribute to understanding (i) the mechanism of intrusion of the basaltic rnelts and (ii) the metamorphic processes occurring in the evaporites caused by mobile phases during volcanism. Hence, the following methods were applied: The mineralogical and chemical description of the basaltic rocks with recent nomenclature including the possible differences between individual dikes and between surface- and subsurface-exposed basalts. Seven surface and 48 subsurface exposures at the Hattorf mine of Kali & Salz AG were studied. Application of the most recent knowledge on basalt genesis for interpreting observational and experimental results. Studies on the sulfur and carbon isotope distributions of the native sulfur from several subsurface exposures and the enrichments of gases (predominantly CO2) in the evaporites. Calculation of the spatial and temporal temperature distribution in the evaporite rocks following intrusion of the basaltic melts. For purposes of clarity a few of the terms which will be used frequently here will first be defined: basalt - all of the intrusive rocks studied can be assigned mineralogically and chemically to the basalt family in a broader sense. Thus, the terms basaltic rock or, in short, basalt will be used for these rocks. rock salt - instead of the term salt for halitic rocks the term rock salt is used. Besides, the evaporites are generally designated as host rocks (for the basalt dikes) as well. gases - especially in the German literature the term carbon dioxide or carbonic acid (= Kohlensäure) is frequently used for the gases enclosed in the evaporites of the Werra-Fulda district. ACKERMANN et al (1964) found, in addition to carbon dioxide, considerable amounts of nitrogen and minor amounts of methane. In the following therefore the terms gas mixture or gas will be used. The various basalt dikes found in the Hattorf mining field are described here in terms of their mineralogy and geochemistry for the first time. In doing so it is necessary to number them from east to west. To avoid confusion with older numerations (e.g. SIEMENS 1971) the various dike systems are designated by capital letters (A to P).

    Description / Table of Contents: PREFACE In a densily populated industrialized country, waste disposal must be compatible with the requirements of the environment. This is one of the indispensable requirements to guarantee an effective protection of the environment. In the past years the waste disposal industry has been given increasing attention by the general public as well as the authorities. This confirms the necessity of adapting the quality of waste disposal to the technological standard of the production. While in the past, waste disposal performance was more or less evaluated in terms of short-term costs, there is at present a reorientation in the direction of a science-based waste disposal industry. These new tendencies are taking into account ecological factors as well as the long-term consequences - i.e., for decades and centuries to come - of waste disposal methods. In this light, particular attention is given to the depositing of residues whose utilization does not appear meaningful from an ecological point of view, or would require disproportionate ressources. It is an important concern of the Federal Authorities to encourage the rapid materialization of disposal solutions which can function as ultimate deposits, and which will therefore cause neither water pollution nor gaseous emissions. In view of this goal it is necessary to establish criteria and regulations for the wastes to be deposited as well as for the characteristics of the deposits. This field confronts science with an urgent but rewarding challenge and calls for close collaboration between many different specialized disciplines...

    Description / Table of Contents: INTRODUCTION Sediments are increasingly recognized as both a carrier and a possible source of contaminants in aquatic systems, and these materials may also affect groundwater quality and agricultural products when disposed on land. Contaminants are not necessarily fixed permanently by the sediment, but may be recycled via biological and chemical agents both within the sedimentary compartment and the water column. Bioaccumulation and food chain transfer may be strongly affected by sediment-associated proportions of pollutants. Benthic organisms, in particular, have direct contact with sediment, and the contaminant level in the sediment may have greater impact on their survival than do aqueous concentrations. Following the findings of positive correlations between liver lesions in English Sole and concentrations of certain aromatic hydrocarbons in Puget Sound (Washington) sediment, it can be suspected that such substrates may also be responsible for a host of other serious and presently unrecognized changes at both the organismal and ecosystem levels (Malins et al., 1984). Modern research on particle-bound contaminants probably originated with the idea that sediments reflect the biological, chemical and physical conditions in a water body (Züllig, 1956). Based on this concept the historical evolution of limnological parameters could be traced back from the study of vertical sediment profiles. In fact, already early in this century Nipkow (1920) suggested that the alternative sequence of layers in a sediment core from Lake Zürich might be related to variations in the trophic status of the lake system. During the following decades of limnological research on eutrophication problems sediment aspects were playing only a marginal role, until it was recognized that recycling from bottom deposits can be a significant factor in the nutrient budget of an aquatic system. Similarly, in the next global environmental issue, the acidification of inland waters sediment-related research only became gradually involved. Here too, it is now accepted that particle-interactions can affect aquatic ecosystems, e.g. by enhancing the mobility of toxic metals. In contrast to the eutrophication and acidification problems, research on toxic chemicals has included sediments aspects from its beginning: Artificial radionuclides in the Columbia and Clinch Rivers in the early sixties (Sayre et al., 1963); in the late sixties heavy metals in the Rhine River system (De Groot, 1966) and methyl mercury (Jensen & Jerne- 16v, 1967) at Minamata Bay in Japan, in Swedish lakes, in Alpine Lakes, Laurentian Great Lakes and in the Wabigoon River system in Canada; organochlorine insecticides and PCBs in Lakes St. Clair and Erie during the seventies (Frank et al., 1977); chlorobenzenes and TCDDs in the Niagara River system and Lake Ontario in the early eighties (Oliver & Nicol, 1982; Smith et al., 1983). In the present lecture notes, following the description of priority pollutants related to sedimentary phases (Chapter 2), four aspects will be covered, which in an overlapping succession also reflect the development of knowledge in particle-associated pollutants during the past twenty-five years: - the identification, surveillance, monitoring and control of sources and distribution of pollutants (Chapter 3); - the evaluation of solid/solution relations of contaminants in surface waters (Chapter 4); - the study of in-situ processes and mechanisms in pollutant transfer in various compartments of the aquatic ecosystems (Chapter 5);- The assessment of the envlroD-mental impact of particle-bound contaminants, i.e. the development of sediment quality criteria (Chapter 6). A final chapter will focus on practical aspects with contaminated sediments. Available technologies will be described as well as future perspectives for the management of dredged materials. Here too, validity of remedial measures can only be assessed by integrated, multidisciplinary research. In the view of the growing information on the present subject and owing to the limitations in the framework of this monography, the reader is referred to additional selected bibliography, which is attached at the end of this Chapter i. Additional information on the more recent publications on contaminated sediments is given in the annual review volume of the Journal of the Water Pollution Control Federation, June edition.

    Description / Table of Contents: PREFACE It is increasingly necessary to develop industrial and hydraulic engineering constructions under unfavourable geological or geotechnical conditions. Furthermore, it becomes more and more important to build effectively and economically and to find optimal solutions for a long-term steady function of the constructions. This emphatically demands exhaustive information on the structural situations and engineering parameters of local site assessments by areal investigations of the sites and the petrophysical parameters in situ. This requires, however, the use of geophysical techniques. During the last two or three decades international applied geophysics has systematically developed new possibilities for site investigations for the determination of petrophysical parameters in situ as well as for observation of the system building and site. As in "New techniques in engineering", geophysical methods make it possible to develop areal models of subsurface conditions of building sites, to quantify relevant engineering parameters in situ, as well as to analyze the longterm behaviour of the buildings, which are influenced by internal or external factors. With regard to the broad spectrum of applied geophysics, there are few methods, that especially favour application in engineering and groundwater studies. These methods are distinguished by a relatively simple measuring technique and good measuring progress, e.g. the geoelectrical self-potential method, the geoelectrical resistivity method as well as a newly developed devices for geothermic measurements. There exist numerous publications, broadly scattered in the technical literature, concerning the theoretical bases and applications of these methods, but until now, there have been only a few meetings to exchange experience and results on an international level. This was the aim of the symposium "Detection of Subsurface Flow Phenomena by Self-Potential/Geoelectrical and Thermometric Methods", held in Karlsruhe from 14-18 March 1988. An outstanding part of the symposioum was represented by the results of a research project, coordinated by the University of Karlsruhe (Department of Geology and Institute of Soil and Rock Mechanics) and the Federal Waterway Engineering and Research Institute (BAW), Karlsruhe. Regarding the subject "Experiments to ascertain the relations between hydraulic potentials in the underground and the geoelectrical and thermic potentials set off by these", the research work took four years. The project was sponsered by the Volkswagen Foundation/Hannover. The goal was to develop and test objective techniques for detecting leakages in dams, locating, demarcating and designating quantitatively inhomogeneous spheres in dams with the aim of detecting damage and subsurface flow phenomena as soon as possible. The symposium consisted of a three-day lecture meeting with about 40 papers and a summarizing respectively closing roundtable discussion, a visit to the laboratories and to the in situ constructions within the area of BAW developed in the frame of the research project. This included a technical excursion to the Rhine-Staustufe Iffezheim with its very impressive waterway constructions and an excursion to the Geophysical Observatory near Schiltach (Black Forest). The Observatory belongs to the Universities of Karlsruhe and Stuttgart. Approximately 80 scientists from 15 countries participated the symposium. They were welcomed by the Rector of the University, Professor Dr. A. Kunle and the representative of the Federal Ministry of Traffic, Dr. G. Schröder. Professor Dr. H. Hötzl elucidated the scientific problems and the economical importance of the project as a speaker of the research group. The following papers dealt with the fundamental aspects of geoelectrical and thermometric measurements, with the theory of these methods, the state and developing ter~dencies concerning devices, data acquisition, processing and interpretation as well as noise effects. It became clear that the solution of the complex scientific-technical problems of waterway constructions and environmental protection requires broad, interdisciplinary cooperation and international collaboration. Thus it would be possible to minimize the personnel, temporal and economic efforts. The intended cooperation of geoscientists, engineering geologists, building engineers and representatives of other disciplines make it possible, not only to exchange experiences and results relating to international problems unsolved until now, but also to determine new guidelines with regard to the scientific organization of further investigations. Thus in order to inform all interested parties of the main topics of the symposium and to advance international cooperation in the future, the present review includes a part of the papers and reports of the excursions recommended by the participants of the meeting, which have been divided into the following topics: - Introduction to engineering-geophysical problems and attempts at their solution; - Geoelectrical self-potential measurements; - Geoelectrical resistivity measurements; - Geothermic measurements; - Case histories; - Some topics of the roundtable discussion; - Reports concerning the excursions. The editors wish to thank very much all those, who contributed to the success of the symposium and to the publication of the present report. Finally they venture the note, that the authors theirselves are responsible for the content of their papers.

    Description / Table of Contents: PREFACE Our planet is evolving and changing; its surface is capable of unleashing great violence as its crust is created and destroyed. Quite remarkably, it has been only recently that the fundamental elements of this evolution were fully appreciated, and only within the last decade have there been technologies capable of directly meastLring the global motions of the Earth's crust which are one of the most visible manifestations of these processes. Before the advent of space technologies, the nature of contemporary global plate motions went largely unobserved. These motions were understood from the geological records, and plate rates for million year averages were established_ Fortunately, the revolution in geophysics brought about by the general acceptance of plate tectonic theory has been paralleled by significant advances in space geodesy oceanography and geophysics. New space technologies have rapidly matured, yielding new insights and capabilities for more completely understanding the dynamical properties of the Earth, its oceans and atmosphere. Likewise, the evolving earth sciences capabilities from space are fostering new questions and goals made possible through the creative exploitation of satellite missions. A workshop entitled "The Interdisciplinary Role of Space Geodesy" was held in Erice, Italy, on the island of Sicily on July 23-29, 1988, to discuss the directions and challenges of space geodeys for the decades to come. This international gathering was made possible by the E. Majorana Centre for Scientific Culture int he framework of tis International School of Geodesy. The workshop was sponsored by the Italian Ministry of education, the Italian Ministry of Scientific and Technological Research, the Sicilian Regional Government, the Italian National Institute of Geophysics, and the National Aeronautics and Space Administration of the United States. This volume is the result of the dedicated effort undertaken by an international group of scientists and administrators who have contemplated the challenge of the future of space-based earth science for the next decade. Recognizing the need for defining new milestones both in science and technology, they have developed a detailed report of what could be achieved and what challenges remain after twenty fertile years of space exploration...

    Description: The International Continental Scientific Drilling Program (ICDP) performed a dual-phase scientific drilling project to investigate mountain-building processes called Collisional Orogeny in the Scandinavian Caledonides (COSC). The borehole COSC-1 was drilled through the Lower Seve Nappe, as the first of two 2.5 km deep drill holes close to Åre, central Sweden. The recovered rocks comprise a 1650 m thick suite of high grade gneisses and amphibolites with clear Seve Nappe affinities, while the lower 850 m com-prise rather homogenous mylonitic gneisses with interfingered K-rich phyllonite bands of cm to several m size and some intercalated amphibolites. The different lithologies all crosscut the core in a subhorizontal direction with foliation of gneisses and phyllonites in the same direction. Albite and garnet porphyroblasts with pressure shadows show syn-deformational growth and the same sub-horizontal alignment. The focus was to detect chemical and mineralogical differences in mylonitic and host rocks and to relate these differences to either metasomatism and deformation or inher-ited source rock variance. Another goal of this work is to compare chemical core scanning instruments. For this purpose, two different μ-Energy-Dispersive X-Ray Fluorescence (μ-EDXRF), Laser Induced Breakdown Spectroscopy (LIBS) and hyperspectral imaging tech-niques served to measure seven samples from the lower 850 m of the COSC-1 core. This report will explain the data sets gained during this study. The metadata will be pre-sented in an additional file including XRF data from the AVAATECH XRF core scanner in a text file as well as data sets of the other used devices in original file formats.

    Description: Radial water jet drilling uses the power of a focused uid jet, which is capable of drilling multiple laterals of about 100 m length out of an existing well and thereby stimulating the well with full control on the operational parameters like initial direction of the lateral, length, uid pressure etc. In contrast to hydraulic stimulation treatments, this technology can potentially provide a network of enhanced uid pathways around a geothermal well to intersect with existing high permeable structures like fracture or karst systems within the reservoir, independent of the ambient stress eld. Applying RJD, laterals typically have a diameter ranging from about 25 mm to 50 mm, depending on jetting parameters like pressure and ow rate as well as rock properties. Drilling a single lateral in a cased well requires approximately 12 hours, as the casing has to be penetrated using a coiled tubing operated milling bit before jetting into the formation. In case the target zone is open-hole, jetting a lateral is considerably faster. Compared to conventional hydraulic stimulation treatments with required uid volumes of more than 1000 m3, only a fraction of this is needed for RJD (〈 1 m3). In addition, no pressure will be applied to the reservoir, thereby reducing environmental risk as well as the risk of induced seismicity considerably. Although RJD is investigated and applied in the hydrocarbon industry, applications in geothermal wells are very rare. If the technology can be shown to increase the eciency of a geothermal well, it will provide an interesting alternative to conventional hydraulic stimulation treatments. RJD shows highest eciency in terms of performance increase in reservoirs with low permeability (〈 10 mD). The most important criteria for the well are the minimum diameter (4 1/2" OD casings) and maximum along hole depth (about 5 km). So far, RJD operations have been performed in wells with a an inclination of up to 46 . Technologies, however, have been developed to perfom RJD operations even in horizontal well sections. Depending on the initial production; for tight gas reservoirs the gas production can be improved with a factor 4-7, simulation for geothermal wells suggest a potential performance increase by a factor of up to 3 when 8 laterals of 100 meter are successfully drilled and geological conditions are favourable. Since the potential increase depends on the type of the geothermal reservoir as well as its properties, the improvement factor has to be conrmed by eld experiments. Currently no major hazards to the well have been identied. The main risk associated with a RJD treatment appears to be sand production from the open-hole completion. However since the amount of experience and well-documented cases is limited, not all risks may have been identied at this moment in time. Major uncertainties in the production estimates are the long-term (〉1 year) stability of the jetted laterals and the eect of sub-surface heterogeneity. The jet-ability of typical geothermal reservoir rocks is also not well documented. As the jet-ability strongly depends on physical rock properties and in-situ reservoir conditions, which are signicantly dierent to typical hydrocarbon reservoirs, the feasibility of RJD in dierent geological settings has to be evaluated. Although, RJD presents a low cost stimulation method with currently no major identied risk to the well nor to the environment, experience with RJD in the geothermal industry is rare. Field applications are therefore key to evaluate the potential of the RJD stimulation technology for geothermal applications.

    Description: Developing ow paths or expanding existing pathways in deep geological strata is generally referred to as "stimulation". To extract heat from geothermal reservoirs, stimulation treatments are carried out by injecting water at high pressure into the formation (hydraulic stimulation), by dissolution of certain mineral components, mostly carbonates, thus increasing the hydraulic pathways (chemical stimulation), or by cooling of the rock to induce tensile stresses which helps the fracture expansion (thermal stimulation). The achieved factor of productivity increase by conventional stimulation treatments is reported to be between 1.3 and 25. In petrolium industry a significant decline of the production increase occurs already during the first year after stimulation. The time to refracturing is typically 4 to 7 years. It is not clear whether these values are also appropriate for geothermal applications. The sustainability of the increase in permeability due to thermal stimulation depends on the situation: for an injection well the increase remains for few years. For production wells, the longevity of the stimulation depends on the self-propping ability of the rock. After reviewing the current situation in the field of deep geothermal energy in Europe, dierent stimulation techniques are discussed. Furthermore, case studies of stimulation treatments in deep geothermal reservoirs are presented. In the subsequent chapters the authors present the methods of stimulation treatment in deep geothermal wells to show the increase of productivity, to explain the potential benefits and risks and estimate the economic performance.
