Full textThis integrated study provides significant insight into parameters controlling (1) the acoustic and reservoir properties of microporous limestone and (2) the mechanical behavior of such rocks. This work improves the knowledge of the relationships among rock physic and rock mechanic on one hand, and the microstructural content on the other hand.(1) Petrophysical properties measured from laboratory and logging tools (porosity, permeability, electrical conductivity and acoustic properties) have been coupled with thin section and SEM observations on the EST205 borehole from the Oxfordian limestone aquifer of the Eastern part of the Paris Basin. A major achievement is the establishment of the link between micrite microtexture types (particle morphology and nature of inter-crystal contacts) and the physical response. Fluid-flow properties are enhanced by the progressive augmentation of intercrystalline microporosity and associated pore throat diameter, as the coalescence of micrite particle decreases between relatively coarser tight morphologies and microporous morphologies. The slow increase of P-wave velocity can be seen as a reflection of crystal size and growing contact cementation leading to a more cohesive and stiffer micrite microtexture. By applying poroelasticity theory on our samples, we show that velocity dispersion can be a very useful tool for data discrimination in carbonates. Finally, a possible origin of high porous levels in neritic limestones is a mineralogical dissolution of carbonates through freshwater-related diagenesis during subaerial exposure time.(2) Regarding rock mechanic, conventional triaxial experiments were performed on samples from the Oolithe Blanche formation (Middle Jurassic Limestone, Paris basin) to investigate the effect of different microstructural parameter on the mechanical behavior of microporous carbonate rocks. Type A samples display two different microporosity distributions within the grains (uniform versus rimmed microporosity) and type B samples are based on the presence/absence of an isopachous cement around the ooids. This work is of primary importance since the Oolithe Blanche formation, a deep saline aquifer, is a possible target for CO2 sequestration and geothermal production in the center of the Paris Basin. Experiments were performed under saturated state with respectively two sets of experimental conditions: (1) a 5 MPa pore pressure and a 28 MPa confining pressure with a temperature of 55°C for Type A carbonates to mimic in-situ conditions in the Center of the Paris Basin; and (2) a 0.5 MPa pore pressure and a 1.5 MPa confining pressure for Type B samples. Sample types have similar facies and composition (oolithic microporous grainstone with a 500µm average grain size), and porosity ranges from 17% to 20%. Permeability values are also very similar and range from 10-2 mD to 10-1 mD.(1) Type A samples with a rimmed porosity display a typical behavior of the brittle failure regime with stress-strain curves reaching a peak (138 MPa) beyond which strain softening was recorded, and strain localization on a shear fracture. (2) Type A samples with a uniform porosity display a ductile behavior with no localization of the deformation.(2) Type B samples with isopachous cement show a brittle behavior with stress drop (16 MPa to 18 MPa) and localization on a shear fracture. When isopachous cements are absent, a more ductile type of behavior is observed. Our set of data suggests that those two microstructural parameters have a significant control on the mechanical behavior of carbonate rocks

Full textDiagenesis refers to all the physicochemical processes that transform sediments. In the Mississippian Limestone, the rocks have been submitted to a complex geological and diagenetic history that makes its hydrocarbon exploitation difficult. Now, the oil and gas industry faces important challenges to keep production plateau and identify remaining productive areas. Therefore, the characterization and interpretation of diagenetic processes are crucial in order to understand the evolution and distribution of porosity and permeability properties. Moreover, diagenesis is rarely taken into account in the standard modeling of carbonate reservoirs. This can be explained by the difficulties in the modeling of diagenetic overprints and the complexity added in the historical adjustment of production data. This work addresses the diagenesis characterization and modeling of carbonate rocks, applied to a core extracted from the Mississippian Limestone. And an innovative methodology is proposed to incorporate the diagenetic phases inside the geological model as part of the modeling and the history-matching workflow

Full textThe present study is an experimental and numerical work on the propagation of seismic waves in carbonate rocks at the laboratory-scale. We aim at producing seismic data that are comparable with field data so as to transfer the knowledge and techniques acquired and developed in field into the laboratory. In return, well-controlled laboratory-scale data can contribute to benchmarking tests on the latest imaging approaches as well as data processing procedures. Ultrasonic probes on natural rocks are fairly common in numerous engineering fields such as geophysical logging, civil engineering and materials science. In terms of ultrasonic sources, both the conventional piezoelectric transducer (PZT) and the laser-ablation pulse are used as a seismic source in our experimental configurations. In terms of receivers, a single-point Laser Doppler Vibrometer (LDV) is employed in most of the experimental setups. Additionally, a 3D wavefield-scan LDV has been used to perform multi-component measurements. The originality of this work consists in the comprehensive characterization of the laser source in a geophysical context and its use as a point-like megahertz source on the carbonate cores, which enabled us to propose original and efficient core-probing configurations for both experimentation and simulations. We developed and validated an experimental prototype featuring PZT-LDV or Laser-pulse-LDV as source-receiver configurations for high-resolution measurements. As to the numerical simulation, we adapted a Fortran code, initially dedicated to method developments at the field-scale, to the numerical production at the high-frequency (HF) laboratory-scale. We will show the results of calibrations on both the experimental and numerical tools including the polarization analysis on multi-component data, the results of the laser pulsed source characterization and the main tomography results from the First Arrival Travel-time (FAT) Tomography (FATT) featuring multi-grids, along with the parallelized 2D/3D simulations featuring the Interior Penalty Discontinuous Galerkin method (IPDGm). A brief demonstration of anisotropy analyses from FAT will also be given at the end. The latest generation of imaging method involves both the observed and synthetic data, such as the promising Full Waveform Inversion (FWI) that can push further the resolution limits of the classical tomography, which is the key motivation of our studies involving both the experiment and simulation

Full textThe aim of the present work is to study the structural, mechanical and vibrational properties of calcium carbonate and strantianite. These two rocks belong to the carbonate family and they are abandonment in the earth 's crust. They are subject to geological constraints that expose them to high pressures, which may reach several GPa. It is then interesting to predict their behaviour in these extreme cases by studying the evolution of their elastic properties as a function of pressure. To do this we have used the molecular dynamics method based on knowledge of an appropriate potential. The physical quantities used to characterize the behaviour of these two kinds of rocks are: the elastic wave velocities, the vibrational modes of phonons and the variation of enthalpy. For CaCO3 the potential parameters employed allow us to evaluate ail mechanical properties. The obtained values are in good agreement with experimental results for aragonite and post-aragonite phases. The variation of the enthalpy as a function of pressure has shown that the post-aragonite phase was stable for pressures above 35 GPa. ln addition to the enthalpy, the structural phase transition from aragonite to post-aragonite phase is confirmed by further results. These latter are the variation of the transversal wave velocities and the variation of trequency of the soft mode, which shows a abrupt jump at the transition pressure. For the SrCO3 we have followed the same procedure as for CaCO

Full textThe mechanical behaviour of limestones is brittle at low confining pressure and becomesductile with the increase of the confining pressure. The brittle behaviour is characterisedby a macroscopic dilatancy due to crack propagation, leading to a stress drop when crackscoalesce at failure. The ductile behaviour is characterised by a a diffuse deformation due tointra-crystalline plasticity (dislocation movements and twinning) and microcracking. The aimof this work is to examine the influence of temperature, pore fluid, strain rate, and time onthe mechanical behaviour. Triaxial deformation experiments were performed on white Tavellimestone (porosity 14.7%). The macroscopic behaviour is then modelled.Constant strain rate triaxial deformation experiments and stress-stepping creep experimentswere performed. Elastic wave velocities were inverted in term of axial crack densities. Themechanical behaviour is brittle for constant strain rate deformation experiments performed atPc · 55 MPa. In this case, inelastic deformation is due to cracks propagation. For Pc ¸ 70 MPa,elastic compaction is followed by an inelastic compaction. Porosity collapse is due to intracrystallineplasticity and micro-cracking. After some inelastic compaction, volumetric strainturns to dilatancy because crack nucleate at dislocation pile-ups and their contribution to thestrain becomes predominant compared to plastic pore collapse. In the brittle regime, watersaturationdecreases the differential stress at the onset of crack propagation and enhancesmacroscopic dilatancy. Temperature decreases the confining pressure at the brittle-semibrittle(ductile) transition. A model describing the macroscopic behaviour is derived from (1) a crackpropagation law, (2) a plasticity law for a porous medium, and (3) a law for nucleation of newscracks due to local dislocation pile-ups. The model predicts the volumetric strain, the stresstensor, and the evolution of damage, as a function of applied deformation. Theoretical resultsare in good agreement with experimental observations
