Abstract:
We present a preliminary investigation of compression of segmented 3D seismic volumes for the rendering purposes. Promising results are obtained on the base of 3D discrete cosine transforms followed by the SPIHT coding scheme. An accelerated version of the algorithm combines 1D discrete cosine transform in vertical direction with the 2D wavelet transform of horizontal slices. In this case the SPIHT scheme is used for coding the mixed sets of cosine-wavelet coefficients.

Abstract:
High-resolution 4D (HR4D) seismic data have the potential for improving the current state-of-the-art in detecting shallow ([Formula: see text] below seafloor) subsurface changes on a very fine scale (approximately 3–6 m). Time-lapse seismic investigations commonly use conventional broadband seismic data, considered low to moderate resolution in our context. We have developed the first comprehensive time -lapse analysis of high-resolution seismic data by assessing the repeatability of P-cable 3D seismic data (approximately 30–350 Hz) with short offsets and a high density of receivers. P-cable 3D seismic data sets have for decades been used to investigate shallow fluid flow and gas-hydrate systems. We analyze P-cable high-resolution 4D (HR4D) seismic data from three different geologic settings in the Arctic Circle. The first two are test sites with no evidence of shallow subsurface fluid flow, and the third is an active seepage site. Using these sites, we evaluate the reliability of the P-cable 3D seismic technology as a time-lapse tool and establish a 4D acquisition and processing workflow. Weather, waves, tide, and acquisition-parameters such as residual shot noise are factors affecting seismic repeatability. We achieve reasonable quantitative repeatability measures in stratified marine sediments at two test locations. However, repeatability is limited in areas that have poor penetration of seismic energy through the seafloor, such as glacial moraines or rough surface topography. The 4D anomalies in the active seepage site are spatially restricted to areas of focused fluid flow and might likely indicate changes in fluid flow. This approach can thus be applied to detect migration of fluids in active leakage structures, such as gas chimneys.

Abstract:
Manual fault mapping in 3D seismic interpretation is labor-intensive and time-consuming. Complex fault geometries and the distortion of the seismic signal close to faults complicate full automation of the fault-mapping process. We present a semiautomatic fault-tracking method for 3D seismic data that consists of fault highlighting followed by model-based fault tracking. Fault highlighting uses log-Gabor filters for emphasizing oriented amplitude discontinuities at faults in the presence of noise. Subsequent fault tracking fits an active contour to the highlighted fault voxels. The active contour searches for a connected, smooth curve which fits the data and disambiguates misleading or missing information. The fault tracker requires the interpreter to place the active contour close to a fault on one initial seismic inline (2D pick). The active contour deforms to the closest amplitude dis-continuity highlighted. This tracking result is then projected forward to the next inline, providing an initial fault pick on this section that is again optimized by the active contour. Tracking results on a series of successive seismic sections, finally, constitute a 3D fault surface. User interaction is solely required for an approximate fault pick on the first inline, and in cases where the fault line is lost due to insufficient signal. Use of the autotracker prototype provides a fast solution for the mapping of complete 3D fault surfaces of constant dip, and for the automated tracking of fault portions within distinct dip domains, if fault surfaces are curved (i.e., listric). The method was applied to a series of high-quality reflectivity sections extracted from a 3D seismic volume from shallow-offshore Nigeria, with the tracking results (generated within seconds) comparing well with manually interpreted fault surfaces.

Abstract:
When present, surface-consistent (shot and/or receiver) phase instability will generate surface-consistent time shifts that are at least partially removed from seismic data when surface-consistent residual statics corrections are applied. The phase instability will not be fully corrected and lingers undetected in the data throughout the remainder of the processing workflow. After processing finishes, seismic interpreters often need to apply laterally varying phase rotations to tie their onshore 3D seismic data to synthetic seismograms, before starting detailed stratigraphic interpretation projects. We have developed and tested a new surface-consistent seismic processing workflow that can be applied to increase the phase stability of our seismic data. It is run after the final pass of conventional surface-consistent residual shot and receiver statics corrections have been applied to optimally align the seismic traces. The phase stability corrections are estimated from an additional pass of surface-consistent residual shot and receiver statics corrections that are calculated on the phase-independent seismic trace envelopes. We demonstrate the application of the workflow using synthetic and real seismic data. We gained confidence that the workflow was performing as expected after we intentionally phase rotated a small subset of the shots and receivers in our seismic test data sets and observed that the workflow corrected these intentionally phase-rotated traces with a high level of accuracy.

Abstract:
The use of hydrocarbons is ubiquitous in modern society, from fuel to raw materials. Seismic surveys now routinely produce large, volumetric representations of the Earth's crust. Human interpretation of these surveys plays an important part in locating oil and gas reservoirs, however it is a lengthy and time consuming process. Methods that provide semi-automated aid to the interpreter are highly sought after. In this research, texture is identified as a major cue to interpretation. A local gradient density method is then employed for the first time with seismic data to provide volumetric texture analysis. Extensive experiments are undertaken to determine parameter choices that provide good separation of seismic texture classes according to the Bhattacharya distance. A framework is then proposed to highlight regions of interest in a survey with high confidence based on texture queries by an interpreter. The interpretation task of seismic facies analysis is then considered and its equivalence with segmentation is established. Since the facies units may take a range of orientations within the survey, sensitivity of the analysis to rotation is considered. As a result, new methods based on alternative gradient estimation kernels and data realignment are proposed. The feature based method with alternative kernels is shown to provide the best performance. Achieving high texture label confidence requires large local windows and is in direct conflict with the need for small windows to identify fine detail. It is shown that smaller windows may be employed to achieve finer detail at the expense of label confidence. A probabilistic relaxation scheme is then described that recovers the label confidence whilst constraining texture boundaries to be smooth at the smallest scale. Testing with synthetic data shows reductions in error rate by up to a factor of 2. Experiments with seismic data indicate that more detailed structure can be identified using this approach.

Abstract:
The importance of seismic anisotropy has been recognized by the oil industry since its first observation in hydrocarbon reservoirs in 1986, and the application of seismic anisotropy to solve geophysical problems has been keenly pursued since then. However, a lot of problems remain, which have limited the applications of the technology. Nowadays, more and more 3D multi-component seismic data with wide-azimuth are becoming available. These have provided more opportunities for the study of seismic anisotropy. My thesis has focused on the study of using seismic anisotropy in 3D multi-component seismic data to characterize subsurface fractures, improve converted wave imaging and detect fluid content in fractured reservoirs, all of which are important for fractured reservoir exploration and monitoring. For the use of seismic anisotropy to characterize subsurface fracture systems, equivalent medium theories have established the link between seismic anisotropy and fracture properties. The numerical modelling in the thesis reveals that the amplitudes and interval travel-time of the radial component of PS converted waves can be used to derive fracture properties through elliptical fitting similar to P-waves. However, sufficient offset coverage is required for either the P- or PS-wave to reveal the features of elliptical variation with azimuth. Compared with numerical modelling, seismic physical modelling provides additional insights into the azimuthal variation of P and PS-wave attributes and their links with fracture properties. Analysis of the seismic physical model data in the thesis shows that the ratio of the offset to the depth of a target layer (offset-depth ratio), is a key parameter controlling the choice of suitable attributes and methods for fracture analysis. Data with a small offset-depth ratio from 0.7 to 1.0 may be more suitable for amplitude analysis; whilst the use of travel time or velocity analysis requires a large offset-depth ratio above 1.0, which can help in reducing the effect of the acquisition footprint and structural imprint on the results. Multi-component seismic data is often heavily contaminated with noise, which will limit its application potential in seismic anisotropy analysis. A new method to reduce noise in 3D multi-component seismic data has been developed and has proved to be very helpful in improving data quality. The method can automatically recognize and eliminate strong noise in 3D converted wave seismic data with little interference to useful reflection signals. Component rotation is normally a routine procedure in 3D multi-component seismic analysis. However, this study shows that incorrect rotations may occur for certain acquisition geometry and can lead to errors in shear-wave splitting analysis. A quality control method has been developed to ensure this procedure is correctly carried out. The presence of seismic anisotropy can affect the quality of seismic imaging, but the study has shown that the magnitude of the effects depends on the data type and target depth. The effects of VTI anisotropy (transverse isotropy with a vertical symmetry axis) on P-wave images are much weaker than those on PS-wave images. Anisotropic effects decrease with depth for the P- and PS-waves. The real data example shows that the overall image quality of PS-waves processed by pre-stack time migration has been improved when VTI anisotropy has been taken into account. The improvements are mainly in the upper part of the section. Monitoring fluid distribution is an important task in producing reservoirs. A synthetic study based on a multi-scale rock-physics model shows that it is possible to use seismic anisotropy to derive viscosity information in a HTI medium (transverse isotropy with a horizontal symmetry axis). The numerical modelling demonstrates the effects of fluid viscosity on medium elastic properties and seismic reflectivity, as well as the possibility of using them to discriminate between oil and water saturation. Analysis of real data reveals that it is hard to use the P-wave to discriminate oil-water saturation. However, characteristic shear-wave splitting behaviour due to pore pressure changes demonstrates the potential for discriminating between oil and water saturation in fractured reservoirs.

A confiabilidade dos dados coletados diretamente ao longo do caminho de poços de petróleo é maior que a confiabilidade de dados sísmicos e, por isto, os primeiros podem ser utilizados para ajustar o volume de aquisição sísmica. Este trabalho propõe um ajuste dos volumes de amplitudes sísmicas através de uma algoritmo de três passos. O primeiro passo é a identificação de feições comuns através de um algoritmo de reconhecimento de padrões. O segundo passo consiste em gerar e otimizar uma malha alinhada às feições de interesse do dado sísmico voluméletrico através de um novo algoritmo baseado em processamento de imagens e inteligência computacional. E o terceiro e último passo é a realização de uma deformação volumétrica pontoa- ponto usando interpolação por funções de base radial para registrar o volume sísmico aos poços. A dissertação apresenta ainda resultados de implementações 2D e 3D dos algoritmos propostos de forma a permitir algumas conclusões e sugestões para trabalhos futuros.
Data acquired directly from borehole are more reliable than seismic data, and then, the first can be used to adjust the second. This work proposes the correction of a volume of seismic amplitudes through a three step algorithm. The first step is the identification of common features in both sets using a pattern recognition algorithm. The second step consists of the generation and the optimization of a mesh aligned with the features in the volumetric data using a new algorithm based on image processing and computational intelligence. The last step is the seismic-to-well registration using a point-to-point volumetric deformation achieved by a radial basis function interpolation. The dissertation also presents some results from 2D and 3D implementations allowing conclusions and suggestions for future work.

Será apresentada uma função de transferência que utiliza três tabelas de cores 1D para compor a uma tabela de cores 3D. O trabalho de Silva[30] sobre opacidade 2D serviu de motivação para o desenvolvimento da técnica de opacidade 3D e ao longo deste trabalho são feitas comparações entre ambos.

Abstract:
Full-waveform inversion (FWI) is a technique that seeks to find a high-resolution high-fidelity model of the Earth's subsurface that is capable of matching individual seismic waveforms, within an original raw field dataset, trace by trace. The method begins from a best-guess starting model, which is then iteratively improved using a sequence of linearized local inversions to solve a fully non-linear problem. In principle, FWI can be used to recover any physical property that has an influence upon the seismic wavefield, but in practice the technique has been used predominantly to recover P-wave velocity, and this is the route that is followed here. Full-waveform tomographic techniques seek to determine a highly resolved quantitative model of the sub-surface that will ultimately be able to explain the entire seismic wavefield including those phases that conventional processing and migration seek to remove such as refracted arrivals. Although the underlying theory of FWI is well established, its practical application to 3D land data, and especially to seismic data that have been acquired using vibrators, in a form that is effective and robust, is still a subject of intense research. In this study, 2D and 3D FWI techniques have been applied to a vibrator dataset from onshore Oman. Both the raw dataset and the subsurface model cause difficulties for FWI. In particular, the data are noisy, have weak early arrivals, are strongly elastic, and especially are lacking in low-frequency content. The Earth model appears to contain shallow low-velocity layers, and these compromise the use of first-arrival travel-time tomography for the generation of a starting velocity model. The 2D results show good recovery of the shallow part of the velocity models. The results show a low-velocity layer that extends across the velocity model, but lacking in a high-resolution image due to the absence of the third dimension. The seismograms of the final inversion models give a good comparison with the field data and produce a reasonably high correlation coefficient compared to the starting model. An inversion scheme has been developed in this study in which only data from the shorter offsets are initially inverted since these represent the subset of the data that is not cycle skipped. The offset range is then gradually extended as the model improves. The final 3D model contains a strongly developed low-velocity layer in the shallow section. The results from this inversion appear to match p-wave logs from a shallow drill hole, better flatten the gathers, and better stack and migrate the reflection data. The inversion scheme is generic, and should have applications to other similar difficult datasets.

Abstract:
The application of 3D seismic data to the study of fault evolution has greatly increased our understanding of how normal and thrust faults propagate. Specifically, by combining displacement distribution plots and a thorough analysis of the fault geometry, we can determine: linkage history, restrictions to fault growth, and blind versus emergent propagation. However, these methods have never been applied to strike-slip faults in seismic data due to the difficulty in imaging kinematic indicators or piercing points that quantify displacement. This thesis presents a novel technique that allows for the rapid identification of kinematic indicators in two 3D seismic datasets from the Levant Basin, Eastern Mediterranean, which enables the displacement distribution of strike-slip faults to be analysed beyond what has been accomplished by traditional field-based studies. The high quality of the data also enables the detailed investigation into the 3D geometry of strike-slip faults to be used in conjunction with the displacement data to better understand the upward vertical propagation history. Results indicate that high displacement faults show distinctly different geometries from low displacement faults, and that strain rate and propagation mode may be integral in controlling geometry type. Furthermore, the geometry of the naturally occurring examples presented here, shows distinct differences from analogue studies, and suggests future work should be applied to understanding what controls these discrepancies. The displacement distribution also allowed insight into fault network relationships at the regional scale, in addition to individual faults. In particular, the 3D geometry of conjugate intersections, branching intersections, and tip structures was explored. The results yielded very complex and confounding structural relationships, which suggest that deformation is rarely as simple as 2D interpretations show, and thus may have significant consequences to precious resource extraction.

Neste trabalho apresentamos um algoritmo baseado em agrupamento de dados para o mapeamento automático de horizontes e de falhas sísmicas a partir de dados sísmicos 3D. Apresentamos uma técnica para quantizar o volume sísmico de entrada a partir dos neurônios do grafo resultante do processo de treinamento de uma instância do algoritmo Growing Neural Gas (GNG). No conjunto de amostras de entrada utilizadas pelo GNG, cada amostra representa um voxel do volume de entrada, e retém informações da vizinhança vertical desse voxel. Depois da etapa de treinamento, a partir do grafo gerado pelo GNG um novo volume quantizado é gerado, e nesse volume possíveis ambigüidades e imperfeições existentes no volume de entrada tendem a ser minimizadas. A partir do volume quantizado descrevemos uma nova técnica de extração de horizontes, desenvolvida com o objetivo de que seja possível mapear horizontes na presença de estruturas geológicas complexas, como por exemplo horizontes que possuam porções completamente desconectadas por uma ou mesmo diversas falhas sísmicas. Também iniciamos o desenvolvimento de uma abordagem de mapeamento de falhas sísmicas utilizando informações presentes no volume quantizado. Os resultados obtidos pelo processo de mapeamento de horizontes, testado em volumes diferentes, foram bastante promissores. Além disso, os resultados iniciais obtidos pelo processo de extração de falhas sugerem que a técnica pode vir a ser uma boa alternativa para a tarefa.
In this work we present a clusterization-based method to map seismic horizons and faults from 3D seismic data. We describe a method used to quantize an initial seismic volume using a trained instance of the Growing Neural Gas (GNG) algorithm. To accomplish this task we create a training set where each sample corresponds to an entry volume voxel, retaining its vertical neighboring information. After the training procedure, the resulting graph is used to create a quantized version of the original volume. In this quantized volume both horizons and faults are more evidenced in the data, and we present a method that uses the created volume to map seismic horizons, even when they are completely disconnected by seismic faults. We also present another method that uses the quantized version of the volume to map the seismic faults. The horizon mapping procedure, tested in different volume date, yields good results. The preliminary results presented for the fault mapping procedure also yield good results, but needs further testing.

Abstract:
In this study 19 tunnel valleys within block 2/4 in the central North Sea basin have been mapped. Furthermore, the possibility for these valleys to act as migration paths for leaked gas has been evaluated. In January 1989 a kick occurred while drilling well 2/4-14 in the area of study, hence the pertinence of evaluating this hypothesis at this locality is evident. The work has been performed using multichannel 2D lines and a conventional 3D seismic survey. The quality of the 2D and 3D data is clearly dissimilar at shallow burial depths, as the 2D data is considered to be high-resolution while the 3D data is low-resolution. However, both data sets have proved to give valuable information on the valley morphology. Great details about the extent and basal morphology have been retrieved from the conventional 3D volume; whereas seismic characteristics of the valley infill have been interpreted from the 2D lines. Tunnel valleys are major, elongated incisions carved into sediments or permeable bedrock during glaciations. They tend to be sinuous in planform, but might also appear as straight valleys. Tunnel valleys often consist of several cut- and fill-structures, both laterally and vertically, and thus form a network of interconnected valleys. This has also been observed in the area of study. No sedimentological logs have been available in the study. Hence, the interpretations of valley fill lithologies are based on the seismic characteristics, and thereby they are quite cautious. The typical fill sequence observed correlates fairly good with similar valleys mapped in the area previously. A lower part of chaotic reflectors, believed to be glaciofluvial sands and gravels, is overlain by sub-horizontal layers of glaciomarine mud. Moreover, velocity pull-up effects are seen in the underburden of some of the valleys. These indicate relatively high velocities of the infill sediments, and hence, it is likely to be clayey tills. Even so, the possibility of gas migration within the tunnel valley system is believed to be conspicuous.

Abstract:
The objective of this work was to develop techniques that could be used to rapidly build a three-dimensional velocity-depth model of the subsurface, using the widest possible variety of data available from conventional seismic processing and allowing for moderate structural complexity. The result is a fully implemented inversion methodology that has been applied successfully to a large number of diverse case studies. A model-based inversion technique is presented and shown to be significantly more accurate than the analytical methods of velocity determination that dominate industrial practice. The inversion itself is based around two stages of ray-tracing. The first takes picked interpretations in migrated-time and maps them into depth using a hypothetical interval velocity field; the second checks the validity of this field by simulating fully the kinematics of seismic acquisition and processing as accurately as possible. Inconsistencies between the actual and the modelled data can then be used to update the interval velocity field using a conventional linear scheme. In order to produce a velocity-depth model that ties the wells, the inversion must include anisotropy. Moreover, a strong correlation between anisotropy and lithology is found. Unfortunately, surface seismic and well-tie data are not usually sufficient to uniquely resolve all the anisotropy parameters; however, the degree of non-uniqueness can be measured quantitatively by a resolution matrix which demonstrates that the model parameter trade-offs are highly dependent on the model and the seismic acquisition. The model parameters are further constrained by introducing well seismic traveltimes into the inversion. These introduce a greater range of propagation angles and reduce the non- uniqueness.

Abstract:

Seismic methods have been used in sedimentary environment for almost 80 years. During that time, exploration geophysicists have developed a number of techniques to handle specific aspects of working in sedimentary areas. This is not the case for studies in the hardrock environment, where significantly less time and money have been invested on seismic investigations. Therefore, there is still a need to develop the right techniques appropriate for working in hardrock environments. The research presented here, covers aspects of acquisition, processing and interpretation in hardrock environments. A cost-effective alternative for two-dimensional data acquisition is presented. Acquisition parameters are also discussed and recommendations for future work are given. The main effort of this thesis, however, was to find appropriate processing methods to address some of the different problems present in datasets acquired in the hardrock environment. Comparison of two computer programs for first arrival seismic tomography was performed in order to find the most suitable one for processing crooked line geometries. Three-dimensional pre-stack depth migration was also tested to find a detailed near-surface image. A processing method geared to enhance the signal-to-noise ratio was applied to the dataset with the lowest signal amplitudes to improve the quality of the stack. Finally, cross-dip analysis and corrections were performed on two of the three datasets included in this thesis. Cross-dip analysis was also applied as an interpretation tool to provide the information needed for estimation of the true dip of some of the reflectors related to geological structures. The results presented in this thesis indicate that cross-dip analysis and corrections are one of the most powerful tools for processing and interpretation in the presence of complex geology. Therefore, it is recommended to include this method as a standard step in the processing and interpretation sequence of data acquired in hardrock environments.

Abstract:
Abstract A 3D surface seismic data acquisition project was conducted simultaneously with 3D DAS-VSP data acquisition in one well in Jilin Oilfield of Northen China. The 3D surface seismic data acquisition project covered an area of 75 km2, and one borehole (DS32-3) and an armoured optical cable with high temperature single mode fiber were used to acquire the 3D DAS-VSP data simultaneously when the crew was acquiring the 3D surface seismic data. The simultaneously acquired 3D DAS-VSP data were used to extract formation velocity, deconvolution operator, absorption, attenuation (Q value), anisotropy parameters (η, δ, ε) as wel as enhanced the surface seismic data processing including velocity model calibration and modification, static correction, deconvolution, demultiple processing, high frequency restoration, anisotropic migration, and Q-compensation or Q-migration. In this project, anisotropic migration, Q-migration was conducted with the anisotropy parameters (η, δ, ε) data volume and enhanced Q-field data volume obtained from the joint inversion of both the near surface 3D Q-field data volume from uphole data and the mid-deep layer Q-field data volume from all available VSP data in the 3D surface seismic surveey area. The anosotropic migration and Q-migration results show much sharper and focussed faults and and clearer subsutface structure.
