Seismic imaging

Identification of fracture zone is a challenging task without the image log data. There are many brownfields around the world where the image log has not been acquired; therefore, there must be an alternative way of fracture identification. In this paper, a conventional log response technique for fracture delineation has been discussed. The study area lies in the Upper Indus Basin of Pakistan, which is sub-divided into the Kohat and Potwar basins. Minwal-X-1 of Joya Mair area, which lies in the Potwar Basin, is selected for this purpose.

The dataset used in this study is the Maui 3D seismic volume from Taranaki basin, offshore New Zealand. A stack of 400 continuous stratigraphic horizons is produced from the Maui RGT model, even for complex areas where classical methods failed to achieve or would take a long time to complete. Integrated with seismic attribute mappings such as RMS amplitude and/or spectral decomposition, the horizon stack enables to navigate the seismic volume in stratigraphic order.

In this study, diffraction imaging is employed in an effort to identify and enhance the fault system inside the basement. The comparison of the study result with various standard post-stack attribute approaches shows the effectiveness of the diffraction imaging method. an oil field in Cuu Long basin.

Searching for hydrocarbon reserves in deep subsurface is the main concern of wide community of geophysicists and geoscientists in petroleum industry. Exploration seismology has substantially contributed to finding and developing giant fields worldwide. The technology has evolved from two to three-dimensional method, and later added a fourth dimension for reservoir monitoring.

This acoustic imaging has identified a canyon system at the slope and a shallow marine fan, which contains shelf incisions extending the İstanbul Strait incision. Multibeam bathymetry, ultra-high resolution seismic profiling and coring correlations on this subaqueous fan area allowed reconstruction of morphology and patterns of sediment distribution indicative of high energy sediment transport processes.

The geology of the Çankırı Basin has been studied using multi-source data including satellite images, aerial photos, gravimetric data and seismic sections, which are subsequently used to generate maps and a 3D model of that part of the basin covered by the seismic sections.

VSP techniques provide information in the vicinity of the borehole. VSP is a class of seismic measurements that can obtain high resolution images near the wellbore (Hardage, 2000). VSP acquisition utilizes sensors deployed within a borehole and sources located at the surface, whereas crosswell tomography uses sources and receivers both deployed in boreholes. The advantage of VSP, crosswell seismic, and other high resolution methods is to obtain more precise estimations of the CO2 induced effects on seismic properties.

Seismic – At the Weyburn Field, multi-component 3-D surface seismic time-lapse surveys were conducted at intervals of approximately 12 months, starting prior to the commencement of CO2 injection in 2000, and repeated in 2001 and 2002. The resultant time-lapse images (primarily seismic amplitude changes) acquired at Weyburn clearly map the spread of CO2 over time within the reservoir, fulfilling a key objective set at the outset of the project.

Signal processing has been playing an increasingly important role in remote sensing, though most remote sensing literatures are concerned with remote sensing images. Many data received by remote sensors such as microwave and geophysical sensors, are signals or waveforms, which can be processed by analog and digital signal processing techniques.

Used as the cost of seismic risk. In the figures, horizontal and vertical axis represents the seismic forces and the total cost and the white and blue parts shows that the initial construction costs and cost of seismic risk, respectively. Each figure presents the results for a fractile hazard curves 0.16, 0.50 or 0.84. The arrows in each image showed the lowest total cost, or seismic design forces the target.

Digital filters are widely used in processing digital signals of many diverse applications, including speech processing and data communications, image and video processing, sonar, radar, seismic and oil exploration, and consumer electronics. One class of digital filters, the linear shift-invariant (LSI) type, are the most frequently used because they are simple to analyze, design, and implement. This chapter treats the LSI case only; other filter types, such as adaptive filters, require quite different design methodologies....
