This book was released on 2011 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: In June 2009, a 2.2 square mile 3-D high resolution seismic reflection survey was shot in southeastern Illinois in the Phillipstown Consolidated oilfield. A well was drilled in the 3-D survey area to tie the seismic to the geological data with a synthetic seismogram from the sonic log. The objectives of the 3-D seismic survey were three-fold: (1) To image and interpret faulting of the Herald-Phillipstown Fault using drillhole-based geological and seismic cross-sections and structural contour maps created from the drillhole data and seismic reflection data, (2) To test the effectiveness of imaging the faults by selected seismic attributes, and (3) To compare spectral decomposition amplitude maps with an isochron map and an isopach map of a selected geologic interval (VTG interval). Changes in the seismic attribute values in the selected interval and along various time slices throughout the whole dataset correlate with the Herald-Phillipstown faults. Overall, seismic attributes could provide a means of mapping large offset faults in areas with limited or absent drillhole data. Results of the spectral decomposition suggest that if the interval velocity is known for a particular formation or interval, high-resolution 3-D seismic reflection surveys could utilize these amplitudes as an alternative seismic interpretation method for estimating formation thicknesses. A VTG isopach map was compared with an isochron map and a spectral decomposition amplitude map. The results reveal that the isochron map strongly correlates with the isopach map as well as the spectral decomposition map. It was also found that thicker areas in the isopach correlated with higher amplitude values in the spectral decomposition amplitude map. Offsets along the faults appear sharper in these amplitudes and isochron maps than in the isopach map, possibly as a result of increased spatial sampling.

Available in PDF, EPUB and Kindle. Book excerpt: The Wabash Valley Seismic Zone (WVSZ), or Wabash Valley Fault System (WVFS), is an intraplate region of higher-than-average seismicity located within the Illinois Basin. This region has produced three 5.0+ magnitude earthquakes within the last 50 years, and recent paleoseismological studies have also shown evidence for 7.0+ magnitude events occurring within the history of the fault system. The prominent faults within the system have very little surface expression, so available data of the orientation, trend, and extent of the fault system comes from seismic reflection data and are observed at depth within mine shafts throughout Illinois. The Wabash Valley faults are contained between the LaSalle Anticlinal Belt, a prominent Precambrian complex of en echelon folds to the north, and the junction of the east/west trending Cottage Grove and Rough Creek faults to the south. Most of the faults trend to the NE and can display vertical offsets into the hundreds of meters, penetrating the Precambrian basement rock at depth. Though there are some similarities in fault orientation and trend to the faults contained within the New Madrid Seismic Zone to the SE, the possible connection to and the tectonic setting of the Wabash Valley Seismic Zone is ambiguous. As part of the Earthscope project to map the crustal structure of the North American continent, data was passively collected along a 400-kilometer Flexible Array across Illinois and Indiana for the purpose of wide angle and deep seismic profiling in the form of tomography. Utilizing a new ray tracing methodology based on Dijkstra's algorithm, tomograms of the study area were created by inverting for Vp data collected from this array. Our tomograms show no evidence for a rift pillow system under the Wabash Valley as predicted, but there is evidence for a dipping fast anomalous zone that has been previously hypothesized from reprocessed COCORP data. We consider this COCORP reflector as an upper layer of eclogite above old, subducted crust with a higher impedance contrast than the surrounding mantle material. Further investigation is warranted, particularly with respect to ray directionality as rays arriving from north of the array do not travel through the fault system itself, whereas southern rays do. It is our hope that further studying including only southern ray paths may illuminate a supposed rift pillow system.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project, at the Savannah River River Site (SRS) was to acquire, process, and interpret 28 km (17.4 miles) of high resolution seismic reflection data taken across the trace of the Pen Branch fault and other suspected, intersecting north-south trending faults. The survey was optimized for the upper 300 ft of geologic strata in order to demonstrate the existence of very shallow, flat lying horizons, and to determine the depth of the fault or to sediments deformed by the fault. Field acquisition and processing parameters were selected to define small scale spatial variability and structural features in the vicinity of the Pen Branch fault leading to the definition and the location of the Pen Branch fault, the shallowest extent of the fault, and the quantification of the sense and magnitude of motion. Associated geophysical, borehole, and geologic data were incorporated into the investigation to assist in the determination of optimal parameters and aid in the interpretation.

Book Synopsis Simultaneous Source Seismic Acquisition by : Ray Abma
Download or read book Simultaneous Source Seismic Acquisition written by Ray Abma and published by SEG Books. This book was released on 2020-12-31 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces simultaneous source technology and helps those who practice it succeed. Although the book does not include all developments, which would have entailed a much longer treatise, this work is written through the lens of decades of experiences and allows readers to understand the development of independent simultaneous sourcing. The relationships between data acquisition and data processing are discussed because never before have they been so intertwined as in this area. In addition to describing the underlying technologies, this book also is a user-guide which discusses survey design and acquisition and decribes the sensitivities of the processing algorithms which can allow simultaneous source technology to succeed. The audience for this book includes acquisition and processing geophysicists who will work with these data as well as those who require only an overview of the state of the art; and, even though they may not need the full technical details, they may want to know the limitations and advantages of using simultaneous sources.
