What is/are Three Dimensional Seismic?Three Dimensional Seismic - This study also estimates seismic moment releases of shallow VLFEs at the Japan Trench observed by onshore seismic stations using Green's function in a local three-dimensional seismic velocity model.  Then methods of deriving these quantities from well logs and three-dimensional seismic data were summarized.  Based on the analysis of three-dimensional seismic data in Hongqi sag, it is clear that the structure of the depression is controlled by volcanic mechanism, controlled subsidence fault and secondary fault.  Here, we present a three-dimensional seismic velocity model of an active fluid conduit beneath the Scanner Pockmark in the Central North Sea, derived from ocean-bottom seismometer data.  To validate the property model, an integrated assessment using wireline logs, microseismic, and three-dimensional seismic data was conducted.  Considering research outcomes of previous studies, this study used three-dimensional seismic and logging data to identify Y- or H-type and the en echelon distribution patterns of the fault plane, as well as identify the locations wherein the fault growth index value is greater than 1 in the study region, indicating the tectonic background of the fault transfer zone in the region.  Curvature analysis methods have lately been developed to assist this for analysing three-dimensional geological surfaces which do not need to assume cylindricity, but these methods are often applied to three-dimensional seismic horizons which have specific considerations that can affect scale analysis. 
In our work-flow, a merged three-dimensional seismic cube covering an area of approximately 50 x 40 km2 was analyzed: 7 master horizons and several proportional slices were delineated in different attribute maps (e. At the surface, further geophones were installed to shape a permanent three-dimensional seismic array.  Numerous paleo-pockmarks are identified and imaged using three-dimensional seismic reflection data and hosted by fine-grained sediments of the Middle Eocene Laing Formation.  This study investigates the internal configuration and stacking patterns of well-defined prograding clinothems within the middle Eocene Gialo Formation in the Assamoud Oilfield of the Sirte Basin through an integrated analysis of wire-line log and three-dimensional seismic data.  Here we show a possible roll-over slab beneath the Caroline microplate, revealed from its three-dimensional seismic velocity structure derived by analyzing teleseismic reverberating SS phases.  By using recently acquired three-dimensional seismic data, a series of unusual confined and semiconfined sedimentary units with seismic reflection patterns different from those of previous studies have been identified.  Based on the three-dimensional seismic dataset, we consider a key area in Beibuwan Basin, South China Sea, combined with quantitative analysis method, in order to define the features of transfer zone, and its temporal spatial development mechanism is revealed.  The proposed scheme was performed on two-dimensional synthetic data with a signal-to-noise ratio of 2 and three-dimensional seismic data containing fault events.  In this paper, the sequence stratigraphy, sedimentary characteristics and distribution characteristics of the granular shoal deposits of the southwestern section of the Kaijiang–Liangping Trough in the Sichuan Basin were investigated, through core observations, thin section analysis, and field profiles measurement and sampling, combined with well-logging data and interpretations of two and three-dimensional seismic data of the local area.  Analysis of two- and three-dimensional seismic data reveals that the channel was present only during the last ~3.  Borehole-controlled interpretation and analysis of two-dimensional and three-dimensional seismic data sets from the eastern Dampier subbasin indicate that a northeast-trending basement weakness zone was subjected to west-northwest–east-southeast oblique extension in the latest Triassic–late Middle Jurassic, resulting in systematic segmentation of the Rosemary fault system (RFS).  Three-dimensional seismic data acquired over the basin have helped greatly in imaging and visualization of stratigraphy and structure, leading to robust understanding of the subsurface.  The imaged three-dimensional seismic velocity structures were associated with the seismotectonical and geological context of the Ecuadorian margin to give insights about the main features controlling the occurrence of large megathrust earthquakes in the region.  In this study, based on the interpretation of three-dimensional seismic data, the structural characteristics of the Shun I strike-slip fault zone were identified.  Hydrocarbon migration patterns and pathways were studied on the basis of three-dimensional seismic interpretation, drilling, geochemistry, production performance, and other data.  In this study, three-dimensional seismic data, outcrops, cores, imaging logs, and thin sections were used to classify faults and fractures at multiple scales. 
In this work we analyzed the three-dimensional seismic site response of the Central Archaeological Area of Rome, which includes the Palatine Hill, Roman Forum, and Coliseum area. The main keystones during the modeling process based on the results of a comprehensive interpretation of three-dimensional seismic survey together with geological and geophysical data, which will significantly increase the reliability coefficient of forecasting ore deposits, are indicated.  Taking the Yulou oil-bearing sets in some experimental area of the West Depression in Liaohe Basin as an example, based on logs from 400 wells, cores from seven wells, three-dimensional seismic data, and analysis and test data, fine stratigraphic correlation and sedimentary facies analysis have been carried out.  Using three-dimensional seismic reflection data covering the outer fold-and-thrust belt of the Niger Delta, we determined the pathways of Miocene to Pliocene channels that crossed, at 173 locations, 11 fold-thrust structures for which the temporal and spatial evolution of strain rates has been constrained over a period of 11 m.  We transfer Bayesian m c mapping developed for natural seismicity to the context of induced seismicity, here adapted to local three-dimensional seismicity clouds.  Based on existing geological understanding, in this paper, the tracking attribute parameters of three-dimensional seismic data bodies are optimized by ant tracking technology.  Ant tracking was used to identify the subvertical basement-rooted faults from a three-dimensional seismic reflection survey.  Here, seafloor and subsurface data are reconciled through an integrated study of high-resolution bathymetry and three-dimensional seismic data imaging a ca 150 km stretch of the trench-axial Hikurangi Channel, offshore New Zealand.  Using the data of three-dimensional seismic interpretation, logging, core description and thin section identification, it is concluded that the formation of volcanic reservoirs in Santanghu Basin was controlled by many factors such as tectonics, lithology, lithofacies, fluids, volcanic apparatus, weathering and leaching, including fault rebuilt, unconformity, alkali metasomatism, dissolution, weathering and leaching and other formation mechanisms, 5 types of reservoir formation models are obtained according to the different superimposition modes of the depth mechanism for the formation of volcanic reservoirs in different periods, and five types of distribution law of effective volcanic oil and gas reservoirs are summarized from the understanding of reservoir types, accumulation models, and accumulation mechanisms.  We propose a new attribute of these signatures: namely, the ratio of the absolute peak and the absolute trough immediately below the peak, which is applied to the three-dimensional seismic data in the Moxi area.  This paper uses high-quality three-dimensional seismic data to investigate curved, strata-bound domino-style faults above which a pockmark field is observed and interpreted to be associated with their formation.  The adoption of three-dimensional seismic isolation system is effective to decrease the seismic loading on the structures.  For this assessment we use three dimensional seismic reflection data, borehole data from ancient deposits in the Maranon foredeep basin of Peru, as well as digital elevation and satellite imagery data from the present day fluvial systems of the Amazonian Basin in the same area of Peru.  In this study, based on the interpretation of three-dimensional seismic data, the structural characteristics of the Shun I strike-slip fault zone were identified.
