Abstract:
Through series of dynamic triaxial tests, the relationships of soil deformations under irregular seismic loading and fixed-number constant amplitude loading are analyzed. The effect of loading amplitudes on the relationships is presented. The results shows: (1) soil deformation under irregular seismic loading obviously differs from that under constant amplitude sinusoidal loading, and the strain history is mainly controlled by the performance of ground motion; (2) if 20 cycles of constant amplitude loading is employed instead of irregular seismic loading to correct residual deformation under real seismic loading, loading amplitudes have no effect on soil deformation under irregular waves and fix-number waves.

Abstract:
Seismic data are rich in information about subsurface formations and their pore content. This information can be retrieved from the amplitude or frequencies of seismic signals. Spectral decomposition is a seismic interpretation technique that enables interpreters to decompose the broadband of seismic signals into constituent frequencies. Likewise, amplitude components analysis (ACA) is an approach proposed to compute amplitude constituent components as a function of offset. The approach uses amplitude-variation-with-offset approximations to extract amplitude components that compose the amplitudes in stacked sections. ACA can be used to screen seismic data for possible hidden anomalies that may be associated with hydrocarbons. ACA also helps predict seismic responses at angles where data are not recorded or are of poor quality. Because abnormal expressions associated with hydrocarbons can be observed in clastic and carbonate formations, the approach can look for the expressions in both types of reservoir rocks.

Abstract:
The partition of plane seismic waves at plane interfaces introduces changes in seismic amplitude which vary with angle of incidence. These amplitude variations are a function of the elastic parameters of rocks on either side of the interface. Controlled‐amplitude processing is designed to obtain the true amplitude information which is geologic in origin. The offset‐amplitude information may be successfully used to predict the fluid type in reservoir sands. Various tests were carried out on a seismic profile from the Gulf Coast. The processing comparison emphasized the effects and pitfalls of trace equalization, coherent noise, offset, and surface‐related problems. Two wells drilled at amplitude anomaly locations confirmed the prediction of hydrocarbons from offset‐amplitude analysis. Furthermore, controlled‐amplitude processing provided clues in evaluating reservoir quality, which was not evident on the conventional relative amplitude data.

Abstract:
Compensating for the effects of an acquisition footprint can be one of the most daunting problems when using seismic attributes for quantitative interpretation. This is especially true for unconventional plays because they are on land with accompanying irregular acquisition geometries. Additionally, in such plays, the physical property changes are often small, making the seismic amplitude fidelity critical. We have developed a methodology that integrates a 1D elastic prestack synthetic model with 3D acquisition geometry to accurately model the seismic footprint produced by irregular or insufficient sampling of primary reflectivity. The stacked amplitude response of the modeled survey is then used to mitigate the poststack footprint on the field seismic. Modeling and removing this element of the acquisition footprint quantitatively improve the interpretive value of the mapped seismic amplitudes. In our study area, correlation between seismic amplitudes and well control increased from an [Formula: see text] of 0.053 before correction to an [Formula: see text] of 0.629 after. Our approach is especially effective in situations in which the spatial frequency of the footprint overlaps that of the geologic signal.

Abstract:
Abstract The article is devoted to the role of digital automatic amplitude control in increasing the depth of seismic exploration. It is noted that the depth of productive strata is gradually increasing, at the same time, more powerful explosive sources are being replaced by relatively weak non-explosive ones. Naturally, during processing, it is necessary to pay close attention to the choice of parameters for adjusting the amplitudes. The article provides basic information about the form and amplitude of seismic vibrations, lists the main empirical formulas that characterize the dependence of the amplitudes of seismic vibrations on time. It is noted that when registering seismic vibrations, one has to deal with minimal soil displacements caused by the arrival of a seismic wave at the observation point, which must be amplified millions of times and their adjustment. In this regard, in the digital processing of seismic data, a technique was developed for recovering the true amplitudes, more precisely, the true amplitude ratio. Adjustment while maintaining the true ratio of amplitudes is used only when it is required to study the dynamics of the wave field (dynamic digital processing). The optimal choice of the length of the adjustment operator (or window) is of paramount importance, since with a small adjustment interval (less than 0.1 s), a loss of dynamic expressiveness of the recording may occur, and this is clearly shown in model studies. The article considers the efficiency of choosing the length of the optimal adjustment operator on the example of the Kurovdag area, which has complex both surface and deep seismogeological conditions. A summary of the Kurovdag field is given. An amplitude compensation function for spherical divergence is given, and to compensate for the effects associated with changes in reception and excitation conditions, a surface-matched amplitude adjustment was performed after removing amplitude bursts. A fragment of the time section is given before and after the optimal adjustment of the amplitudes according to the seismograms of the Kurovdag area, which clearly demonstrates how the information content of the time section increases and, thereby, the depth of the seismic exploration: before the optimal digital automatic adjustment of the amplitudes at times of 3.25 - 3.5 sec, no seismic horizons, while after this procedure, dynamically well-defined seismic horizons appear at the same times, reflecting the structure of the medium at great depths.

ABSTRACT*Zefara* Field formation Baturaja on South Sumatra Basin is a reservoir carbonate and prospective gas. Data used in this research were 3D seismik data, well logs, and geological information. According to geological report known that hidrocarbon traps in research area were limestone lithological layer as stratigraphical trap and faulted anticline as structural trap. The study restricted in effort to make a hydrocarbon accumulation and a potential carbonate reservoir area maps with seismic attribute. All of the data used in this study are 3D seismic data set, well-log data and check-shot data. The result of the analysis are compared to the result derived from log data calculation as a control analysis. Hydrocarbon prospect area generated from seismic attribute and are divided into three compartments. The seismic attribute analysis using RMS amplitude method and instantaneous frequency is very effective to determine hydrocarbon accumulation in *Zefara* field, because low amplitude from Baturaja reservoir. Low amplitude hints low AI, determined high porosity and high hydrocarbon contact (HC). Keyword: Baturaja Formation, RMS amplitude seismic attribute, instantaneous frequency seismic attribute

Abstract:
The results of the lithofacial analysis of data from the Moracz 3D seismic survey were among the main premises leading to the positioning of the new petroleum exploration well in that area. Unfortunately, the reservoir properties of the drilled part of the Main Dolomite carbonates differed significantly from those anticipated by the analysis of the amplitudes of the seismic signal recorded. Such surprisingly negative results impelled the reinterpretation of 3D seismic data. Hence, a number of analyses of the amplitudes, the frequencies, and the variability of phase shift were carried out in order to determine the influence of these parameters on the lithofacial interpretation of seismic data. The results revealed a fundamental error of amplitude with the extraction maps. It appeared that the distribution of amplitudes is not essentially controlled by the reservoir properties of the Main Dolomite carbonates but by the fault shadow effect coming from Mesozoic graben in the overburden. In addition, a large diversity of frequency spectra was found, which, combined with the small thickness of the exploration level, could have contributed to incorrect identification of seismic reflections. There was also a change in seismic signatures from the same reflection in different parts of the survey, raising doubts about the distribution of the phase rotation. In order to recognize phase rotation diversity, a new seismic data analysis was based upon the selected Triassic sediments of high impedance. The obtained maps demonstrated significant variability within the data volume due to attenuation. The reinterpreted data from the Moracz 3D seismic survey proved the uneven and unstable distribution of amplitudes, frequencies, and phase which resulted in erroneous conclusions of petroleum exploration. After modeling with the use of different frequency ranges, an analysis of the amplitude extraction of the horizons related to the Main Dolomite was performed. Then the amplitude ratio attribute was selected which eliminated the influence of the regional amplitude and frequency distribution and showed the distribution of dolomite properties more reliably than the amplitude extraction maps.

Abstract:
Seismic amplitude anomalies are attractive exploration targets in the Krishna-Godavari Basin offshore India. These bright spots mostly have very high amplitudes, so confident interpretations have been possible. We distinguished between hydrocarbon-bearing sands, water-bearing sands, and high-impedance nonreservoir bodies. Also, we mapped channel architecture and accurately predicted reservoir thickness. Strong amplitude anomalies, prospective seismic character based on an understanding of data phase and polarity, flat spots, and amplitude versus offset have all provided valuable evidence.

Abstract:
A non-linear singularity-preserving solution to the least-squares seismic imaging problem with sparseness and continuity constraints is proposed. The applied formalism explores curvelets as a directional frame that, by their sparsity on the image, and their invariance under the imaging operators, allows for a stable recovery of the amplitudes. Our method is based on the estimation of the normal operator in the form of an ’eigenvalue’ decomposition with curvelets as the ’eigenvectors’. Subsequently, we propose an inversion method that derives from estimation of the normal operator and is formulated as a convex optimization problem. Sparsity in the curvelet domain as well as continuity along the reflectors in the image domain are promoted as part of this optimization. Our method is tested with a reverse-time ’wave-equation’ migration code simulating the acoustic wave equation.

In this paper, we recover the amplitude of a seismic image by approximating the normal (demigrationmigration)operator. In this approximation, we make use of the property that curvelets remain invariant under the action of the normal operator. We propose a seismic amplitude recovery method that employs an eigenvalue like decomposition for the normal operator using curvelets as eigen-vectors. Subsequently, we propose an approximate non-linear singularity-preserving solution to the least-squares seismic imaging problem with sparseness in the curvelet domain and spatial continuity constraints.

A interpretação sísmica consiste em um conjunto de metodologias que visam compreender o modelo estrutural e estratigráfico de uma determinada região. Durante este processo, o intérprete analisa a imagem sísmica buscando identificar estruturas geológicas como falhas, horizontes e canais, dentre outras. Dada a baixa razão sinal-ruído, os algoritmos que dão suporte à interpretação precisam de uma etapa de pré-processamento onde o ruído é reduzido. Esta tese propõe um novo método de filtragem por difusão anisotrópica que melhor preserva as feições sísmicas de interesse. A formulação do processo de difusão permite que os atributos identificadores de horizontes e de falhas sejam incorporados ao método a fim de evitar que estas estruturas sejam corrompidas durante a difusão da amplitude sísmica. O método proposto implementado apresenta resultados aplicados a dados reais disponíveis na literatura. Para estes resultados, é apresentada uma análise da influência do método de filtragem anisotrópica proposta nas medidas de correlação ao longo de horizontes previamente rastreados. Finalmente, a tese apresenta algumas conclusões e sugestões para trabalhos futuros.
Seismic interpretation can be viewed as a set of methodologies to enhance the understanding of the structural and stratigraphic model of a given region. During this process, the interpreter analyzes the seismic imaging seeking to identify geological structures such as faults, horizons and channels, among others. Given the low signal to noise ratio, the algorithms that support the interpretation require a pre-processing stage where the noise is reduced. This thesis proposes a new filtering method based on the anisotropic diffusion of the amplitude field. The formulation of the diffusion process proposed here uses seismic attributes to identify horizons and faults that are preserved in the diffusion process. The proposed method implemented in this thesis also presents results applied to real and synthetic data. Based on these results, we present an analysis of the influence of the proposed method in correlation measurements over horizons previously tracked. Finally the thesis presents some conclusions and suggestions for future work.

Resumo: Entende-se por datum a superfície onde estão posicionados os pares fonte-receptor usados na aquisição sísmica. Este datum pode ser plano ou irregular e sua profundidade pode variar. O objetivo da redatumação é transformar o dado sísmico adquirido na superfície original em um dado simulado adquirido em outra superfície. Obtém-se assim um novo dado, como se tivesse sido adquirido em uma superfície de geometria e profundidade diferentes. A vantagem deste processo seria eliminar a propagação indesejada da onda sísmica em camadas com forte variação na velocidade. A transformação correta das amplitudes, do dado na superfície original para os dados no novo datum, é de importância fundamental. Um dado com esta propriedade poderia ser usado em diversos processos que necessitam de um dado com amplitude verdadeira, possibilitando melhor caracterização de possíveis reservatórios, por exemplo. Um destes processos seria a migração Kirchhoff em amplitude verdadeira. Na literatura, existem trabalhos que discutem e comprovam que uma transformação de configuração em amplitude verdadeira pode ser obtida encadeando os processos de migração e demigração com funções peso. Nesta tese, nós estendemos este resultado e derivamos um operador de redatumação em amplitude verdadeira, ao considerar que neste encadeamento podemos também mudar a profundidade dos pares fonte-receptor, tanto no dado sísmico de entrada quanto no simulado de saída. Processos Kirchhoff como este dependem de um bom modelo de velocidades para poder calcular as correções de tempo de trânsito de cada traço. Ao longo deste trabalho, foi possível verificar como a cinemática da redatumação independe da velocidade abaixo do novo datum. Esta velocidade afeta apenas a função peso que corrige as amplitudes. No entanto, após alguns testes foi possível verificar que pequenas incertezas inseridas nesta variável produzem pouco erro relativo na amplitude final
Abstract: The surface where the source-receiver pairs used in the seismic aquisition are positioned is called a datum. This datum can be flat or irregular and the depth may vary. The main goal of redatuming is to transform the seismic data acquired on the original surface into simulated data as if acquired on another datum. The advantage of this process is that it can eliminate undesired seismic wave propagation in layers with strong velocity variation or strong topography. The correct amplitude transformation, from the original surface data to the new datum, is of fundamental importance if the data are to be used in subsequent true-amplitude processes that allow better characterization of potential reservoirs, for example. One of these processes is the true-amplitude migration. In the literature, there are studies that argue and prove that a true-amplitude configuration transform can be obtained by chaining the weighted migration and demigration integral operators. In this thesis, we extend this result and derive a true-amplitude redatuming operator. For this purpuse, we consider that in this chaining procedure, we can also change the depth of the source-receiver pairs, either in the input or simulated output configuration. Kirchhoff processes like this one depend on a good velocity model in order to calculate traveltime corrections for each trace. Throughout this work, we demonstrated that the kinematics of redatuming is independent of the velocity below the new datum. This velocity affects only the weight function that corrects the amplitudes. However, our numerical tests indicated that small uncertainties inserted in this variable resulted in little relative error in the final amplitude

Abstract:
To make a prediction for seismic signal propagation, one needs to specify physical properties and subsurface ground structure of the site. This information is frequently unknown or estimated with significant uncertainty. This paper describes a methodology for probabilistic seismic ensemble prediction for vertically stratified soils and short ranges with no in situ site characterization. Instead of specifying viscoelastic site properties, the methodology operates with probability distribution functions of these properties taking into account analytical and empirical relationships among viscoelastic variables. This yields ensemble realizations of signal arrivals at specified locations where statistical properties of the signals can be estimated. Such ensemble predictions can be useful for preliminary site characterization, for military applications, and risk analysis for remote or inaccessible locations for which no data can be acquired. Comparison with experiments revealed that measured signals are not always within the predicted ranges of variability. Variance-based global sensitivity analysis has shown that the most significant parameters for signal amplitude predictions in the developed stochastic model are the uncertainty in the shear quality factor and the Poisson ratio above the water table depth.

LOW-CYCLE FATIGUE PROPERTIES OF AUSTENITIC STAINLESS STEEL S30408 UNDER LARGE PLASTIC STRAIN AMPLITUDE. The Hong Kong Institute of Steel Construction, March 2022. http://dx.doi.org/10.18057/ijasc.2022.18.1.10.

Full text
Abstract:
The application of stainless steel materials in civil structures for seismic protection lies in its low-cycle fatigue characteristic. However, the data of existing research are mainly based on the low-cycle fatigue in small strain amplitudes. To this end, we perform low-cycle fatigue testing of Austenitic stainless steel S30408, which has low yield point and good elongation performance, under the cyclic load with a maximum strain amplitude reaching up to 5%, to fill the gap. The stress-strain response characteristics of the stainless steel material under the cyclic load are analyzed; then, the parameters of the strain-fatigue life relationship and the cyclic-plastic constitutive model used for FEA simulation are extracted. Results show that the stainless steel’s stress-strain curve is nonlinear without a yield plateau, thus presenting a high strength yield ratio and ductility. The hysteresis loops of the material are plump with a shuttle shape and are symmetric to the origin, indicating a fine energy dissipation capacity. The skeleton curve under cyclic loading with cyclic hardening can be significantly reflected by the Ramberg Osgood model, which is affected by the strain amplitude and loading history; it is also different from the monotonic tensile skeleton curve. The strain-fatigue life curve fitted by the Baqusin Manson Coffin model can predict the materials’ fatigue life under different strain amplitudes. The mixed hardening model, including isotropic and kinematic hardening, based on the Chaboche model, is able to simulate the cyclic stress-strain relationship. Further, its parameters can provide basic data information for the seismic design of civil structures when Austenitic stainless steel S30408 is used.

EXPERIMENTAL STUDY AND NUMERICAL ANALYSIS ON SEISMIC BEHAVIOR OF ASSEMBLED BEAM-COLUMN JOINTS WITH CSHAPED CANTILEVER SECTION (ID NUMBER: 197). The Hong Kong Institute of Steel Construction, August 2022. http://dx.doi.org/10.18057/icass2020.p.197.

Full text
Abstract:
"A kind of assembled steel beam-column joint with C-shaped cantilever section was proposed. The influences of the lengths of cantilever sections and cover plates on seismic performance of the joints were discussed through low-cycle reciprocating loading tests and numerical simulations. Then the sensitivity analysis of key parameters such as thickness and width of flange plate ,bolt number and cover plate’s length were carried out. The results show that the joint consumed energy through warping deformations of end plate and the friction slippages between flange of beam, C-shaped cantilever section and cover plate. By reasonably increasing the lengths of C-shaped cantilevers section and cover plates, it can ensure that the joints have high bearing capacities, while significantly improving energy dissipation capacities of the joints. Parameter analysis showed that increasing thickness of the flange plate can effectively improve the stress concentration at root of the cantilever section. Reducing width of flange plate has a great impact on bearing capacity and initial stiffness of the joint with the maximum drop amplitude of 13.1% and 18.9%, respectively."
