This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1977 G.S.I. collected a three dimensional seismic survey over a gas producing salt dome offshore Louisiana. The purpose of this study was to test the 3D seismic system as a development tool to aid bringing new fields into production. The producing structure in this area contains one of the larger gas fields in the United States with reserves of 1.5 trillion cubic feet. The field was discovered in 1950 and has a total of forty-nine wells, thirty-seven producers and twelve dry holes. In this study the well log analysis and the seismic interpretation were carried out completely independent of each other. Direct hydrocarbon indicators, in this case flat spots (hydrocarbon-water contact reflections), were used to seismically determine the extent of the gas accumulation. Thick gas sands in young offshore clastic basins, like the Gulf of Mexico, are the easiest reservoirs to identify using direct hydrocarbon indicators such as bright spots or flat spots. The high density surface coverage associated with a 3D survey enhances flat spot detection. The structure of the reservoir units as well as the hydrocarbon extent in two of the major reservoirs were studied both seismically and by using the wells drilled in the field. These two independent study methods yielded very similar interpretations. With the larger survey area and the higher density surface coverage, the 3D seismic survey yielded a more refined structural interpretation than the well log analysis. In areas of good well control both the interpretations are the same; where the well control diminishes there are some discrepancies. Two additional faults which affect the hydrocarbon accumulation in the D sand were identified using the 3D survey. A major growth fault which controlled the deposition of the reservoir units was mapped more accurately using the 3D survey. The seismic estimates of the hydrocarbon extent are found to be a little conservative compared with the proven producing areas. The reason for this conservative estimate is that the seismic data is low frequency 10-20 Hertz. With data of this bandwidth a significant gas thickness (approximately 100 feet) is required before a gas-water contact reflection can be reliably mapped. Thinner gas pays near the outer producing boundaries were not detected using the 3D survey. In this study the 3D seismic system was used to accurately map the structure and hydrocarbon extent in two of the major reservoirs. Wells producing from these reservoirs confirm findings. If this survey was done in the early 1950’s at least three dry holes could have been prevented during the development of this field. The 3D seismic system is an excellent development tool and in most cases its use will reduce the number of dry holes drilled while defining the limits of new discoveries.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal exploitation of deltaic reservoirs needs detailed facies and architectural element analysis as a base for a comprehensive geological model. To date, very few studies have evaluated regional shelf-margin deltaic systems using 3D seismic data and 3D seismic geomorphologic and seismic stratigraphic analysis. High-resolution 3D seismic data, covering an area of 8,000 km2 offshore Louisiana at the modern shelf edge of the central northern Gulf of Mexico, was used to reconstruct the distribution and evolution of the paleo-Mississippi shelf-margin deltaic system during the last full cycle of fall and rise in sea level, which spans the last 125,000 years. Three-dimensional seismic geomorphological analysis was complemented with computed seismic attributes, including coherence, curvature, spectral components, sweetness, and amplitude gradient, with the objective of identifying shelf-margin geological features not typically observed in seismic profiles. The results show that salt tectonism in the Gulf of Mexico controlled the morphology of the shelf and the slope, forcing the paleo-Mississippi deltaic system to split, and concentrate its progradation and deposition in four separate along-strike salt-withdrawal minibasins. Each minibasin shows different deltaic constructional patterns. Progradation and aggradation patterns vary from minibasin to minibasin due to the response of the sediment supplied by the paleo-Mississippi delta, variations on sea level, the morphology of the seafloor, the arrival angle when the delta reaches the upper slope minibasin, and the shape of the minibasin. The 3D reconstruction of the system shows lateral variation of the deltaic processes from wave- to fluvial-dominated; wave-dominated deltaic strandplains were identified in the western minibasins and fluvial distributary channels were recognized in the eastern minibasins. This research highlights the importance of lowstand wave-dominated deltaic strandplains as important elements for the transport of sediment from the shelf to the slope in a salt-controlled setting like the Gulf of Mexico. The fluvial dominated shelf-margin delta is also related to direct transfer of sediment from the shelf to the slope

Available in PDF, EPUB and Kindle. Book excerpt: Elements of 3D Seismology, third edition is a thorough introduction to the acquisition, processing, and interpretation of 3D seismic data. This third edition is a major update of the second edition. Sections dealing with interpretation have been greatly revised in accordance with improved understanding and availability of data and software. Practice exercises have been added, as well as a 3D seismic survey predesign exercise. Discussions include: conceptual and historical foundations of modern reflection seismology; an overview of seismic wave phenomena in acoustic, elastic, and porous media; acquisition principles for land and marine seismic surveys; methods used to create 2D and 3D seismic images from field data; concepts of dip moveout, prestack migration, and depth migration; concepts and limitations of 3D seismic interpretation for structure, stratigraphy, and rock property estimation; and the interpretation role of attributes, impedance estimation, and AVO. This book is intended as a general text on reflection seismology, including wave propagation, data acquisition, processing, and interpretation and will be of interest to entry-level geophysicists, experts in related fields (geology, petroleum engineering), and experienced geophysicists in one subfield wishing to learn about another (e.g., interpreters wanting to learn about seismic waves or data acquisition).

Available in PDF, EPUB and Kindle. Book excerpt: 3-D seismic data have become the key tool used in the petroleum industry to understand the subsurface. In addition to providing excellent structural images, the dense sampling of a 3-D survey makes it possible to map reservoir quality and the distribution of oil and gas. Topics covered in this book include basic structural interpretation and map-making; the use of 3-D visualisation methods; interpretation of seismic amplitudes, including their relation to rock and fluid properties; and the generation and use of AVO and acoustic impedance datasets. This new paperback edition includes an extra appendix presenting new material on novel acquisition design, pore pressure prediction from seismic velocity, elastic impedance inversion, and time lapse seismics. Written by professional geophysicists with many years' experience in the oil industry, the book is indispensable for geoscientists using 3-D seismic data, including graduate students and new entrants into the petroleum industry.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis interprets and maps some key stratigraphic and structural elements of Garden Bank (GB) Block 191 applying both geological and geophysical techniques. The area is located in the Gulf of Mexico 160 miles southwest of Lafayette. Three-dimensional seismic data and some well logs were integrated and analyzed to construct a reasonable geological subsurface image. GeoFrame software from Schlumberger was used in this research. A spatial attention was given to salt diapers [i.e. diapirs]. Their influence on sand accumulations and hydrocarbon traps were investigated. Two Pleistocene sands accumulations (4500-ft & 8500-ft) were examine thoroughly in this research. Time and amplitude maps were produced. In addition, a wave-theoretical model that describes salt tectonic activities within the area was reconstructed in order to understand the influence of these dynamical forces on the overlaying strata.
