Neste trabalho estudam-se as propriedades físicas e mecânicas das rochas da Bacia do Rio do Peixe (BRP), provenientes do furo estratigráfico 1-BSB01-PB. Esta bacia, localizada no extremo oeste do estado da Paraíba, tem se tornado alvo de estudos exploratórios, face à ocorrência de óleo próximo a superfície, à NW da cidade de Sousa. Em sua caracterização faciológica, identificam-se cinco fácies sedimentares: calcilutito vermelho, calcilutito cinza, arenito, folhelho negro e marga. Por meio de ensaios de propagação de ondas sísmicas, experimentos de petrofísica básica, e ensaios mecânicos de compressão uniaxial com o martelo de Schmidt, determinam-se para as amostras de rochas da BRP, a porosidade, as densidades total e de grão, as velocidades sísmicas, a resistência mecânica e as constantes elásticas estáticas e dinâmicas, destacando-se o módulo de Young. Os resultados obtidos mostram que as rochas em estudo apresentam valores de porosidade entre 0,5 e 20%, resistência à compressão uniaxial de 18 a 93 MPa, módulos de Young dinâmicos entre 9 a 58 GPa, desde 1,1 até 6 vezes maiores que os correspondentes módulos estáticos. As correlações observadas para as diferentes propriedades físicas e mecânicas mostram-se fortemente influenciadas por características como presença de material carbonático, matéria orgânica, óleo e estruturas sedimentares e tectônicas, evidenciando a complexidade das rochas analisadas.
In this paper, studies on physical and mechanical properties of rocks from the stratigraphic hole 1-BSB01-PB, in the Rio do Peixe Basin (BRP), are performed. This basin, located in the far west of the state of Paraíba, has become the subject of exploration studies due to the occurrence of oil near the surface, in the NW of Sousa city. In his facies characterization is possible to identify five sedimentary facies: red calcilutite, gray calcilutite, sandstone, black shale and marl. From seismic wave propagation tests, experiments of basic petrophysics, mechanical tests on uniaxial compressive with Schmidt’s hammer, are determined for samples of BRP rocks the porosity, the bulk and grain densities, the seismic velocities, the mechanical strength and the static and dynamic elastic constants, highlighting the Young's modulus. The results obtained show that the studied rocks have porosity values between 0.5 and 20%, uniaxial compressive strength from 18 to 93 MPa, dynamic Young's modulus between 9 and 58 GPa, from 1,1 to 6 times greater than the corresponding static modules Correlations observed for the different physical and mechanical properties shows strongly influences by characteristics such as the presence of carbonate material, organic material, oil and sedimentary and tectonic structure, showing the complexity of the analyzed rocks.

A petrofísica computacional é uma técnica que vem sendo utilizada cada vez mais na indústria do petróleo para caracterizar reservatórios e simular computacionalmente o seu comportamento físico. Através dessa técnica é possível caracterizar um elevado número de amostras, sob diferentes condições ambientais, em um tempo relativamente curto. Este trabalho propõe um modelo de estimativa de permeabilidade que utiliza parâmetros petrofísicos retirados de imagens de microtomografia de raios x (µCT) e os compara com parâmetros petrofísicos medidos em laboratório. Foi analisado um conjunto de 19 amostras com características deposicionais, diagenéticas e texturais diferentes entre si, pertencentes às bacias do Araripe, Potiguar e Sergipe-Alagoas. Delas, 14 são de calcário, 2 de tufa calcária, 2 de caliche e 1 de dolomito. Em laboratório foi utilizado um permoporosímetro a gás para medir os parâmetros porosidade e permeabilidade. As amostras de µCT foram adquiridas com resolução em torno de 2,0 µm. O conjunto de imagens criado foi tratado no software Avizo Fire e foram extraídos os parâmetros porosidade, permeabilidade, conectividade e diâmetro equivalente de poros. Um modelo estatístico foi estabelecido para predição da permeabilidade a partir dos parâmetros do espaço poroso extraídos das imagens de µCT. Os resultados indicam que a conectividade dos microporos, inferida a partir do cálculo do Número de Euler em imagens 3D, é o parâmetro que exerce maior influência na estimativa da permeabilidade, seguida pela porosidade dos macroporos e pela conectividade dos macroporos. O modelo preditivo proposto apresentou um coeficiente de determinação de 0,994, mostrando-se bastante confiável para o grupo de amostras investigado.
Computational petrophysics is a technique that has been increasingly used in the petroleum industry to characterize reservoirs and to simulate computationally its physical behavior. Through this technique it is possible to characterize a big number of samples, under different environmental conditions, in a relatively short time. This work proposes a model of permeability estimation that uses petrophysical parameters taken from x - ray microtomography images (µCT) and compare them with petrophysical parameters measured in the laboratory. It was analyzed a set of 19 samples with different depositional, diagenetic and textural characteristics, belonging to the Araripe, Potiguar and Sergipe - Alagoas basins. Of these, 14 are limestones, 2 of tufa limestone, 2 of caliche and 1 of dolomite. In the laboratory a gas permoporosimeter was used to measure the porosity and permeability parameters. µCT samples were obtained with a resolution of about 2.0 μm. The set of images created was treated in Avizo Fire software and the porosity, permeability, connectivity and pore diameter parameters were extracted. A statistical model was established to predict permeability from pore space parameters extracted from µCT images. The results indicate that the connectivity of micropores, inferred from the calculation of the Euler Number in 3D images, is the parameter that exerts the greatest influence in the estimation of permeability, followed by the porosity of the macropores and the connectivity of the macropores. The proposed predictive model presented a coefficient of determination of 0.994, being very reliable for the group of samples investigated.

Повний текст джерелаO objetivo deste estudo foi ampliar o conhecimento em mecânica de rochas evaporíticas e aplicar a mecânica computacional na modelagem numérica do comportamento estrutural de poços de petróleo em zonas de sal. Amostras de rochas evaporíticas de anidrita, halita, carnalita e taquidrita pertencentes à sequência evaporítica Ibura da Formação Muribeca, testemunhadas em poços de petróleo, foram submetidas a ensaios laboratoriais de mecânicas de rochas, em especial a ensaios triaxiais de fluência sob diferentes condições de estado de tensões e temperaturas. Nas mesmas condições de ensaio triaxial de fluência a taquidrita desenvolveu deformação axial específica de cerca de 107 vezes maior que a halita e 2,7 vezes maior que a carnalita, sendo que a anidrita permanece essencialmente indeformável. Para os ensaios triaxiais de fluência com a halita na temperatura de 86 graus Celsius foi possível definir o mecanismo duplo de deformação por fluência, enquanto que para a carnalita e a taquidrita isto ocorreu nas temperaturas de 130 e 86 graus Celsius, respectivamente. A taxa de deformação por fluência em regime permanente obtida por simulação numérica reproduziu fielmente os resultados experimentais dos ensaios triaxias de fluência, com erro relativo inferior a 1 por cento. Através dos ensaios laboratoriais foram obtidos os parâmetros geomecânicos de fluência das rochas ensaiadas e a seguir aplicados nos modelos numéricos de simulação, construídos para avaliar a influência de diversos parâmetros nos estudos de estabilidade de poços e integridade de revestimentos. A desconsideração da interação geomecânica entre estruturas salíferas e o maciço hospedeiro pode conduzir a falhas na perfuração de poços próximos a tais estruturas devido ao processo de halocinése do sal que altera o estado de tensões gravitacional.
The aim of this study was to increase knowledge of evaporitic rock mechanics and apply computational mechanics in numerical modeling of structural behavior of oil wells in areas of salt. Evaporitic rock samples of anhydrite, halite, carnallite e tachyhydrite and belonging to the evaporitic sequence Ibura from the Muribeca formation, coring in oil wells, were subjected to laboratory tests of rock mechanics, especially the triaxial creep under different states of stress and temperature. Under the same conditions of triaxial creep tachyhydrite developed specific axial strain rate about 107 times that of halite and 2.7 times that of carnallite, and anhydrite remains essentially undeformed. For the triaxial creep of halite in the temperature of 86 degrees Celsius it was possible to define the double mechanism creep law, while for carnallite and tachyhydrite this occurred at temperatures of 130 and 86 degrees Celsius, respectively. The creep rate in steady state condition obtained by numerical simulation accurately reproduced the experimental results of the triaxial creep tests, with a relative error less than 1 percent. Through laboratory tests geomechanical creep parameters of the tested rocks were obtained and then applied in numerical simulation models, designed to evaluate the influence of various parameters in the well stability and casing design. The lack of consideration of the geomechanical interaction between the salt structures and the host rock can lead to drilling failures in wells near such structures due to the salt halokinesis process that changes the gravitational stress state.

Hydraulic fracturing is an essential tool used to enhance connectivity in shale gas reservoirs by maximizing the intersection between the hydraulic fracture (HF) and pre-existing natural fractures (NF) or faults. The technique is most effective when the hydraulic fracture crosses natural fractures rather than arresting on them. Experiments conducted to examine the interaction between HF and artificial pre-existing faults suggest that the coupling of diffusivity and fault slip is an important element of the HF-fault interaction problem. Fault slip, once activated is associated with an apparent increase in diffusivity. Whether the hydrofracture crosses or arrests on the pre-existing fault is also affected by surface roughness, differential stresses, and fault slip mode (i.e., stable or stick-slip sliding). Calibrated piezoelectric transducers were used to measure acoustic emissions (AE) generated during HF and fault slip.
Moment tensor analysis of these events was used to distinguish pure tensile, shear, and possibly closure events during the experiments. Seismic moment magnitudes were approximately -7 for events during the initiation of the HF and about -5 for events during fault slip. Such a low ratio of seismic moments for tensile and slip events may explain the small numbers of tensile events recorded during reservoir stimulations. I also studied the time-dependent behavior in shales to gain insight into the post-stimulation efficiency of exploitations. Shale experiences strain hardening and compaction during loading by both isostatic (pressure-driven) and differential stress (shear-driven). Transient creep strain increased linearly with log(time), possibly transitioning to constant rate in timescale of several days. Motivated by the multi-scale nature of heterogeneities in shales, I examined the micromechanics of deformation using the nano-indentation technique.
Elastic and creep moduli found in nano-indentation and triaxial tests agreed within a factor of 2, but within that factor, the creep strength may depend on spatial scale.

Computational rock mechanics becomes more and more popular. New programs are constantly under development, and the modelling process has become a natural part of the planning process for many caverns and tunnels, as well as for the mining and petroleum industry.
When to use continuous modelling in preference to discontinuous modelling and vice versa, is an important question that has been discussed for a long time.
For this purpose, in this work continuous and discontinuous modelling is applied in order to analyze the stability of the Gjøvik Olympic Mountain Hall. The large span cavern (62m) was built in connection with the XVII Winter Olympic Games 1994 at Lillehammer, and is a unique case study because of the large amount of available input data from a comprehensive stress and deformation monitoring program carried out during and after the excavation, as well as thorough pre-investigations. Phase2, a two-dimensional non-linear finite element program, and the Discontinuous Deformation Analysis (DDA) are used as representative tools for continuous and discontinuous modelling, respectively. DDA is both a theory and a computer program. The modelling procedure is similar to the distinct element modelling, while it more closely parallels the finite element method with respect to: i) Minimizing the total potential energy to establish equilibrium equations, ii) Choosing displacements as unknowns of the simultaneous equations and iii) Adding stiffness, mass and loading submatrices to the coefficient matrix of the simultaneous equation.
In general, the decision to use either continuous or discontinuous modelling should be based on data from the geological field mapping process. Mapping techniques which remove subjectivity from the results, for example scanline/area mapping or semi-automatic mapping, are recommended. If the rock mass is basically free of discontinuities, or if the discontinuities are very closely spaced in comparison to the dimensions of the problem to be analysed, continuous modelling is preferable. If large deformations including slip, rotation and separation are dominant, as for rock slope stability problems, discontinuous modelling may be selected. If the problem to be analysed cannot be classified within one of the two groups, the quality of required input parameters and the purpose of the modelling should be taken into consideration.
For underground hard rock problems as the Gjøvik Olympic Mountain Hall, continuous modelling is strongly recommended. Today’s mapping techniques are not good enough to give satisfactory information about the required and most crucial input for discontinuous modelling, namely the joint pattern, and the process for implementation of measured discontinuities into a numerical model is based on too many approximations. In addition, the discontinuous modelling process is very time consuming. A fast and high capacity computer is required.
Crucial input parameters for continuous modelling are strength and deformability parameters of the rock mass, and estimation of these parameters is dependent on the selected failure criterion, usually either Mohr-Coulomb or Hoek-Brown.
The magnitude of in-situ stresses, particularly the horizontal stresses, may have crucial influence on the general stability, and independent of whether continuous or discontinuous modelling is selected, in-situ stress measurements are strongly recommended in order to estimate a reasonably correct stress level for the problem to be analysed.
It is very difficult to estimate reliable input parameters for numerical modelling and a critical evaluation of the analysis results is absolutely recommended. Thus, analysis results should be considered as valuable additional input to field observations, in-situ and laboratory measurements, and experience rather than a precise answer for the given problem.
