    Mechanical and Hydraulic Aspects of Rock-Proppant Systems : Laboratory Experiments and Modelling Approaches (2011)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: [...] In context of this work, a new damage mechanism is proposed: the mechanically induced fracture 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 understand the hydraulic and mechanical interactions in the rock-proppant system. In order to analyse the hydraulic and mechanical interactions, laboratory experiments using three different flow cells were conducted. These flow cells were used to localise and quantify the mechanical damage at the fracture face, as well as to investigate the long-term stability of a rock-proppant system under in-situ reservoir conditions.

    Identification of kinematic boundary conditions triggering removal of material in tectonically erosive margins : insight from scaled physical experiments (2013)
    Deutsches GeoForschungsZentrum GFZ

    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: This study represents the first investigating potential kinematic boundary conditions for subduction erosion in a systematic manner. For the subduction erosional process, the aperture at the box's rear, which allowed rearward material loss, was shown to have the largest influence on obtained results. If the amount of material leaving the system was larger than the amount of material subducted at the wedge's toe, the margin evolved as erosional. We found the surface slope to be the second important parameter, which strongly controls the amount of basally eroded material.

    Mineralogical-geochemical effects during geological storage of CO2 : experimental investigations and geochemical modeling (2013)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: In order to analyze mineralogical-geochemical changes occurring in whole rock reservoir samples (Stuttgart Formation) from the Ketzin pilot CO2 storage site, Brandenburg/Germany as well as to investigate single fluid-mineral reactions laboratory experiments and geochemical modeling were performed. The whole rock core samples of the Stuttgart Formation were exposed to synthetic brine and pure CO2 at experimental P-T conditions and run durations of 5.5 MPa/40 °C/40 months for sandstone and 7.5 MPa/40 °C/6 months for siltstone, respectively. Mineralogical changes in both sets of experiments are generally minor making it difficult to differentiate the natural variability of the whole rock samples from CO2-induced alterations. Results of sandstone experiments suggest dissolution of analcime, anhydrite, the anorthite component of plagioclase, chlorite + biotite, hematite and K-feldspar. Dissolution of anhydrite, the anorthite component of plagioclase and K-feldspar is also observed in siltstone experiments. During equilibrium simulations best matching models were ranked based on a mathematical statistical dispersion relation. The best matching model comprises a mineral combination of the albite component of plagioclase, anhydrite, dolomite, hematite, and illite. The equilibrium modeling showed that it is difficult to match K+, Fe2+ and SO4 2- brine concentrations simultaneously. The best matching subsets of the equilibrium models were finally run including kinetic rate laws. These kinetic simulations reveal that experimentally determined brine data was well matched, but reactions involving K+ and Fe2+ were not completely covered. Generally larger mismatches for dissolved Al3+ and Si4+ in all the completed simulations are most likely related to the sampling strategy and respective inaccuracies in the measured concentrations of dissolved Al3+ and Si4+. The kinetic simulation suppressing mineral precipitation yields best matches with experimental observations. The modeling shows acceptably well matches with measured brine ion concentrations, and the modeling results identified primary minerals as well as key chemical processes. It was also shown that the modeling approach is not capable of completely covering complex natural systems. Experiments on mineral separates were conducted with 2 M NaCl brine and pure CO2 using siderite, illite and labradorite samples. Experimental P-T conditions were 20 (30) MPa and 80 °C; run durations were one (siderite), two (illite) and three weeks (labradorite), respectively. Based on the acquired set of mineralogical-geochemical data the distinct experiments show: (i) dissolution of ankerite and stable siderite, which is therefore interpreted to be a potential CO2 trapping phase, (ii) preferred dissolution of the Ca-smectite component out of the illite-smectite mixed-layer mineral and (iii) dissolution of labradorite, respectively. No mineral precipitates (e.g. carbonate phases) were detected in any of the conducted laboratory experiments, and only one single kinetic simulation predicts the formation of minute amounts of dolomite. Based on the data acquired during this dissertation the mineralogical-geochemical effects of CO2 are minor, and the (chemical) integrity of the Ketzin reservoir system is not significantly affected by injected CO2.

    Earth's magnetic field : observation and modelling from global to regional scales (2011)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report STR
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: The magnetic field of the Earth varies in space and time. Geomagnetism as research area that aims to describe and understand the sources of these variations is supported by two pillars: first, regular high-precision measurements in the global network of magnetic observatories and repeat stations are necessary to register the field and its variations at all. Second, mathematical methods are required in order to extract magnetic field models from this large data set. Methods applied to data offer insights in the mechanisms generating the magnetic field. This thesis covers both subjects. In a first part, following the description of the state of the art in observatory instrumentation, I explain in detail two instruments that have the potential to streamline the classical procedures: The Geomagnetic AUtomated SyStem GAUSS paves the way to automated absolute measurements, up to now only possible manually. The newly developed DI3 technique improves and simplies the standard manual measurements signicantly and thus reduces the requirements placed on observers. The second part deals with the mathematical tools available for geomagnetic field modelling. I focus on harmonic splines that can be derived from the classical approach of spherical harmonics. These base functions are interpolatory and have a localised shape while satisfying Laplaces equation. Hence, they are applicable to fit data regionally or globally. The harmonic splines are used with a data set made of repeat station and observatory measurements from Southern Africa. This region is of special interest because the field intensity is very low and and both spatial and temporal field gradients exist. Subdivided into an analysis of ancient (years 1961-2001) and recent (2005-2009) data, two continuous regional field models SAMS and X-SAMS are derived. From the analysis of the field models, a better understanding of the field behaviour is gained. Finally, the harmonic splines are used in a case study on globally distributed secular variation data. Rotating the data set in a system of coordinates aligned with the dipole axis and modelling it with the harmonic splines reveals the external origin of observed fast variations.

    In:  Scientific Technical Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: [...] In this thesis, data from seismic and infrasound stations were analyzed in order to see effects of tsunamis of the great Sumatra-Andaman 2004 and Tohuku-Oki 2011 earthquakes. Data used are from seismic stations of the Global Seismic Network (GSN) around the Indian and Pacific oceans and from infrasound stations of the International Monitoring System of the Comprehensive Test Ban Treaty Organization (IMS/CTBTO). In both data sets, seismic and infrasound, tsunami signals are observed in the period range of 500to2000s. These data may add to two new very useful observables for tsunami early warning systems.

    Combined evaluation of strong motion and GPS data for analyzing coseismic deformation caused by strong earthquakes (2013)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: We recover coseismic static surface deformation by double integration of strong motion accelerometric data. Compared to GPS measurement, the advantage of strong motion data is that they have the potential to provide real-time coseismic static displacements. Strong motion data, however, has the classic problem of baseline offsets which produce unrealistic displacements after double integration is applied. We adopted a bilinear line fitting of empirical baseline correction method to overcome such problem. We investigate the improvement methods of baseline correction that constrain the maximum flatness of the displacement trace and use the cumulative energy ratio as a threshold. We apply the methods to data sets of the 2003, Mw 8.3 Tokachi-Oki earthquake, the 2007, Mw 7.7 Tocopilla earthquake, the 2010, Mw 7.8 Mentawai earthquake and the 2011, Mw 9.0 Tohoku earthquake. We show that, in general, the results of strong motion derived displacements are comparable to nearby GPS data for most data sets, although for far-field data the method may lead to poor results. It confirms that cumulative energy ratio is appropriate to be used as a threshold of baseline correction method. The very large and very good quality of boreholes strong motion data of the Tohoku earthquake gives opportunity to investigate the method deeply. We analyze the dependency of the method on hypocenter distance, magnitude and rupture model of the earthquake. We found that the method has a strong dependency on the given parameters, particularly on hypocenter distance. We also show that the method should be distinguished for horizontal and vertical components. Using our improvement method in this study, the deviations of vector length between strong motion derived displacements and nearby GPS data either for horizontal or vertical components, are significantly minimized. Further study, we optimize the use of valuable rapid static displacement data obtained from strong motion or GPS near-source station. We introduce a centroid grid search method to calculate the moment magnitude by using Okada (1985) model. Our method calculates reasonable moment magnitude using data even only from single station. This method can be done very rapidly within about 5 minutes. It provides crucial information e.g. for making tsunami warning decision.

    Well-log based determination of rock thermal conductivity in the North German Basin (2013)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Technical Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: [...] The approach followed in this study is based on the detailed analyses of the relationships between thermal conductivity of rock-forming minerals, which are most abundant in sedimentary rocks, and the properties measured by standard logging tools (i.e., gamma ray, density, sonic interval transit time, hydrogen index, and photoelectric factor). By using multivariate statistics separately for clastic, carbonate and evaporite rocks, the findings from these analyses allow the development of prediction equations from large artificial data sets that predict matrix thermal conductivity within an error of 4 to 11%, without being affected by the limitations mentioned above.

    Publikationsdatum: 2020-02-12
    Beschreibung: Within this thesis, passive seismic data collected during the two-year TIPAGE deployment in Tajikistan and Kyrgyzstan from 2008 to 2010, are analyzed. This is the first modern digital seismological dataset for this politically unstable region, all previous studies either relied on globally recorded data or some short-term deployments of analog stations in Afghanistan during the late 1960s and 70s. Modern seismological techniques applied to the collected digital seismic data provide a wealth of new constraints on regional crustal and sub-crustal structure, leading to a better understanding of active tectonic processes.

    Publikationsdatum: 2020-02-12
    Beschreibung: The present work tries to condense the state‐of‐the‐art for the exploration and exploitation of geothermal energy. Although a lot of experiences from different sites worldwide are integrated in this study, some sections do reflect the German experience. For example, the German Renewable Energy Sources Act (EEG, see page 78) enables also a specific promotion and growth of the geothermal sector in Germany by guaranteeing special feed‐in tariffs for a 20‐years period. During the last years, several countries worldwide have introduced similar renewable energy promotion policies (some of them restricted to certain energy sources only or requiring a certain renewable energy quote), supporting investigations also in geothermal applications. Thus, the experiences in Germany may be of some value. Dependent on the political‐economical framework, the geothermal exploration and exploitation of deeper reservoirs represents an excellent option to extend geothermal applications also in areas where shallow geothermal reservoirs may not be able to match the local energy demand. Therefore, also challenges related to the exploration and exploitation of deep low‐permeability reservoirs are included in this study.

    Sensitivity analysis for future gravity satellite missions (2011)
    Deutsches GeoForschungsZentrum GFZ
    In:  Scientific Techncial Report
    Details
    Publikationsdatum: 2020-02-12
    Beschreibung: The theme of this thesis is to investigate the sensitivity of several different formations of future satellite gravity missions. The work has three main aspects. The first, and the most important, is the development and testing of a global directional wavelet transformation as a mathematical tool to analyse sensitivity of satellite gravity mission. This is done by propagating full covariance matrices w.r.t. the spherical harmonics functions onto the directional wavelet transform. For the first time, we are able to accurately quantify the stripes that are typical for the error pattern of the GRACE gravity mission. The second aspect is the simulation of a satellite gravity formation, in order to achieve accuracy information in the form of a full covariance matrix. The third aspect involves analyzing results from the GRACE mission, which is already in orbit and has been delivering data since 2002. We compare the simulations of GRACE to the data delivered by the GRACE mission. This way, we are able to establish a relationship between the simulations and real-life data and evaluate the quality of the simulations.
