Full textThe Jaca basin (Spanish Pyrenees) is a classical example of a foreland basin, where the sedimentary filling and the calendar of thrust activation have been extensively studied. It remains to understand the paleohydrology and the thermal history of the basin, so as to provide a fluid flow model related to its formation and deformation (Paleoecene-Oligocene). To do this, this work proposes to analyze the distribution of fracturing, to study the conditions of formation of syn-tectonic veins and to characterize the maturity of organic matter throughout the Jaca foreland basin, from hinterland to external areas.Petrographical, geochemical and microthermometric analysis of veins show that the vast majority of mineralizing fluids are at the isotopic and thermal equilibrium with the host-rock. In detail, we identified two main events of vein precipitation in the inner part of the basin (Sierras Interiores), probably related to major basement thrust activations. We suggest that fluids flow along decollement levels and are expelled over short distances (<10 km), through fracture networks towards the foreland basin. The other part of the basin mainly record local fluids, sometimes associated with the infiltration of meteoric water. Analysis of burial temperatures (50 °C to 250 °C), which includes Δ47 data, shows a relatively homogeneous N-S organization from the Sierras Interiores (gas window) to Sierras Exteriores (immature), with strong longitudinal anomalies. Thermal 1D modelling of 9 virtual wells suggest that the maximum temperatures of Sierras Interiores result from sedimentary accumulation, whose a large amount is now eroded. We propose that this eroded thickness corresponds to late-orogenic conglomeratic deposits near the axial zone. The data suggest an inhomogeneous distribution of the deposits along an E-W axis, involving more complex sedimentary transfers than usually discussed. Given our results and previous studies, the paleohydrological and thermal model of the Jaca basin, and on a larger scale, of the South Pyrenean fold and thrust belt, is compartmentalized both in space and in time, in response to the propagation of and oblique deformational front, which controls the opening of the system. The paleohydrological and thermal model of the South Pyrenean fold and thrust belt is therefore a potential analogue to fold and thrust belt including shortening due to an oblique convergence

Full textIn metallogeny, it is now obvious that fluids are the main vectors of metals and that fluids and deformations are closely associated in the mineralizing processes. This work deals about this two main aspects in the porphyry and epithermal environment. Fluid studies, realised in the epithermal district of Shila (SW Peru), allow to state a mineralizing model at the district scale. The differences observed in the PVT properties of the fluids seem to explain the different types and styles of mineralization. At Apacheta, studies of the vertical evolution of the physico-chemical parameters of the fluids in parallel to the mineralization show that differences, observed between deep levels (Pb-Zn) and shallower levels (AuAg), is directly linked to a fractionation of gases present in fluids during a boiling event. The geochemistry (crush-leach) of the fluids associated to this type of mineralization in various districts (Shila, Pero; Baia Mare and Apuseni Moutains, Romania; Pongkor, Indonesia) are similar whatever their geodynamic context and are comparable with the fluids associated to geothermal systems. Analyses of fracture networks has been realised at macroscopic scale on different (mineralized or not) vein systems. They allow in a first time to establish a new methodology to characterize paleostresses taking into account the influence of the fluid pressure. Applied on the Soultz-sous-Forêts vein system, this method gives realistic paleostress magnitudes linked to the reopening of quartz veins. The mineralized stockwerk of the Rosia Poieni porphyry copper (Apuseni Mts, Romania) has been chosen for a statistical and hydraulic characterization in order to understand how mineralized vein system evolve and grow. A 1D sampling of the stockwerk has been realized on 2000 fractures distributed on five levels of the open pit (910, 940, 1000, 1045 and 1060 ml. Various statistical analyses has been applied and heterogeneities observed in the stockwerk (metric scale) express directly variations in the copper content. Statistical description of the stockwerk properties seems thus to be a very powerful prospective tool. Estimation of hydraulic conductivities developed by veins has been realized and show equally heterogeneities at the quarry scale. The mean permeability developed by all the veins on each profile decrease from the deeper and more mineralized level (910m) to the highest level (1060m). High permeabilities developed on the 910 m profile are linked to the presence of major drains and the clustered organization of veins. The level 1060 m, characterized by numerous and thin veins with a homogeneous spatial repartition, develop a more pervasive permeability

Full textThe objective of this work is to evaluate the environmental impacts related to hydraulic fracturing operations by studying the adsorption mechanisms of chemicals additives used in fracturing fluids and to predict the evolution of these additives injected in large quantities into the shale. Based on the results obtained, it appears that bentonite has a high adsorption capacity of xanthan additive compared to other minerals contained in the shale. The three-model matrices bentonite, calcite and kaolinite have the same adsorption capacity of sp breaker additive. It also appears that xanthan is a biodegradable product, unlike sp breaker, which is a non-biodegradable product, requiring other treatment methods other than the biological method. These two results allowed us to conclude that Bentonite can be used as an adsorbent for the treatment of return water for the elimination of the two products (xanthan and sp breaker), both of which are present in significant quantities in the return water (flow back) and present a fairly significant environmental problem. The results obtained by the rheology studies showed that the gelling agent (xanthan) has a high viscosity when applied under low shear stress and a low viscosity when applied under high shear stress. This shear stress tends to increase for the samples conserved for 24 hours and needs more energy to be injected into the shale. The water-gelling agent mixture behaves like a rheofluidifying fluid with a critical flow stress and flow is only observed when the applied shear stress is above this critical value. In addition, analytical, numerical and experimental hydraulic fracturing tests carried out in the laboratory on a number of cylindrical samples of synthesized PMMA showed that the flow rate and the initial crack size has more impact than viscosity on breakdown pressure. A good agreement was obtained between the results of the analytical and numerical models compared to the experimental results. The results of the numerical simulation study are nearly the same as the experimental (real) results compared to the analytical study, because the analytical study only takes into account the depth of the crack, but the numerical simulation, which considers the shape of the semi-elliptical crack (half-length and depth).

Full textThis research study aims at developing a lattice-type numerical model allowing the simulation of crack propagation under fluid injection in a quasi-brittle heterogeneous medium. This numerical tool will be used to get a better understanding of initiation and propagation conditions of cracks in rock materials presenting natural joints where the coupling between mechanical damage and fluid transfer properties are at stake. If the final goal of the study does concern natural rocks, the model has been validated by different comparisons with experimental results obtained on cementitious materials mimicking natural rocks in term of mechanical and transport behaviours but presenting heterogeneities which are better controlled. The first part of the manuscript presents a general state of the art. The second part of the manuscript is dedicated to the study of crack propagation in quasi-brittle materials where a significant fracture process zone is evolving upon failure. Only the solid phase is studied here and a statistical tool based on Ripley’s functions is adapted in order to extract a characteristic length representative of the correlations appearing between a set of point undergoing mechanical damage. This tool is then used in the context of numerical and experimental fracture tests on 3 point bending concrete beams. The results show that the lattice-type numerical model is able to capture the global fracture process – in term of force vs. crack opening mouth displacement – but also the local fracture process – in term of dissipated energy and correlation length evolution between damage points. Moreover, this statistical tool shows how the solicitation mode may influence the development of damage within a structure. The third part presents a new elasto-plastic damage constitutive law for joint modelling. The originality of the model lies in the coupling between mechanical damage under normal strain and plasticity under tangential strain. This new constitutive law is able to reproduce indirect shear experimental tests performed on mortar specimens presenting a plaster joint where a classical Mohr-Coulomb criterion fails. The fourth part is dedicated to the representation of the full hydro-mechanical coupling within the lattice-type numerical model. The hydro-mechanical coupling is introduced through a poromechanical framework based on the intrinsic and dual hydro-mechanical description of the lattice model, which is based on a "hydraulic" Voronoï tessellation and a "mechanical" Delaunay triangulation. The total stress links the mechanical stress and the pore pressure through the Biot coefficient of the medium whereas the local permeability, which drives the hydraulic pressure gradient, depends on the local crack openings. The numerical results are compared with analytical solutions from the literature for "bi-wings" shape cracks and it is shown that both approaches present similar results for a perfect straight crack. Once the lattice-model has been successfully validated within the former parts of the manuscript, its fifth and last part is dedicated to the numerical simulation of the fully hydro-mechanical coupling problem of a free crack propagation due to fluid injection and its interaction with a natural joint in an heterogeneous rock medium. Different crack paths, which are not pre-meshed a priori, and different pressure profiles are obtained and compared for different joint inclinations. Finally, our statistical tool, which has been primarily developed for the analysis of the failure behaviour of the solid phase, is used to characterise the evolution of correlation lengths between points undergoing damage upon the crack propagation and its interaction with a natural joint. It is shown that the hydro-mechanical lattice model is able to represent different mechanism of crack stop and restart from a joint depending on its inclination

Full textThis work is focused on interpretation of data obtained on the hot fractured rock geothermal research site of soultz-sous-forêts, during reservoir development and forced circulation tests. The density contrast between fresh cold injected water and hot salted formation fluid implies complex field observations that could be treated by considering the two fluids as immiscible fluids. It was consequently decided to enhance the numerical code fracas, based on a discrete fracture network approach, in order to allow multiphase flows in fractures. The final purpose of this study is to underline eventual density driven flow and to evaluate the invaded reservoir volume during circulation tests

Full textMetallogenic deposits within paleproterozoic basins depend on generation and migration of fluids. The aim of this study is to provide a better understanding of tectonic, sedimentological and diagenetic setting of the uranium deposits in the Franceville basin and to characterize hydraulic fracturing impact on fluid migration processes in sandstone reservoirs.Tectonic study define the N180-170° transfer faults, associated with Archean tectonic and the N110-120° longitudinal normal faults. These two fault directions split the Franceville basin into small sub-basins. The longitudinal normal faults are associated with footwall anticlines and hanging wall synclines. The uranium deposits of Franceville basin are located in footwall anticlines of longitudinal normal faults.Sedimentological analysis allows to describe four depositional environments: Fluvial (lower FA), deltaic (middle FA), tidal (upper FA), and open marine environments (FB). Facies distribution in the FA-FB transition promotes the establishment of permeability barriers. These latter are responsible of the increase in fluid pressure and of the formation of fluid pressure structures (dykes, stylolites, quartz veins), in footwall anticlines of longitudinal normal faults. Increase in fluid pressure allows the migration of uranium-fluids, and hydrocarbon from the deep basin to the footwall anticline. Hydraulic fracturing processes lead the precipitation of uranium mineralization, associated with bitumen, in microfractures
