3D visualization technology makes full use of 3D seismic information and properties. Using 3D graphics to describe all kinds of complex data fields and the data relation can be easily perceived, it is an important method of seismic and geological research. In petroleum exploration, the high performance graphics workstations are deployed to complete the interpretation work. The traditional appli...

Abstract In both industry and academic, the seismic exploration does not yet have the capability of illuminating the physical dynamics with high resolution and in real-time, as it involves collecting the raw seismic data from sensors to data loggers then manually retrieving data for post processing which may take months to complete. This study presents InsightTomo, a In-Situ Seismic Tomographic...

Heavy crude oil is known as oil that is highly viscous and of a higher density than that of conventional oil. Sand reservoirs containing heavy oil generally consist of unconsolidated sediments deposited at a shallow burial depth, with high porosity and permeability. In seismic exploration, acoustic impedance inversion is a commonly used tool in reservoir prediction. However, due to the unconsol...

Geophysical techniques coupled with the modern computer workstation have not been widely used in environmental geology. The Kansas Geological Survey is investigating the application of the computer workstation in a number of projects underway that involve environmental questions and problems associated with salt dissolution. The computer workstation provides an efficient approach to integrate g...

ABSTRACT: Frequent occurrence of seismic activities has drawn attention of various researchers, cutting across science and engineering discipline. The domain of earthquake geotechnical engineering has extended from determination of attenuation of seismic wave to providing suitable foundation under liquefied and unliquefied soil conditions. The seismic data can be fully intrepreated by use of se...

Imaging subsalt structures under the complex overburdens is a challenging task in seismic exploration due to the poor illumination of seismic waves. To solve the illumination problem, geophysicists designed the wide azimuth acquisition. Moreover, WAZ acquisition improves the signal to noise ratio by increasing the azimuthal fold, and reduces multiple interferences in the final images (Etgen, 20...

When accompanied by the appropriate algorithmic approach, seismic imaging is an application that can take advantage of massively parallel computer systems. Three-dimensional (3D) prestack time migration (PSTM) and pre-stack depth migration (PSDM) are key components of seismic imaging and require very large computing resources. In this paper, we show that execution of these algorithms can be dra...

We examined the feasibility of using seismic reflections to image the upper 10 m of the earth’s subsurface quickly and effectively by attaching geophones to a wooden board at 5-cm intervals. The shallow-seismic-reflection information obtained was equivalent to control-test data gathered using classic, single-geophone plants with identical 5-cm intervals. The results were surprising: We found li...

Megafans (100-600 km radius) are very large alluvial fans that cover significant areas on most continents, the surprising finding of recent global surveys. The number of such fans and patterns of sedimentation on them provides new mesoscale architectures that can now be applied on continental fluvial depositional systems, and therefore on . Megafan-scale reconstructions underground as yet have ...
