introduction to seismic stratigraphy

Sediment cores are mostly collected from the ocean floor by organizations like the International Ocean Discovery Program (IODP) using a ship dedicated to drilling (Figure 5.1a). To be effective, it is necessary to teach geologists (and engineers) a bit of geophysics, and geophysicists (and engineers) a bit of geology.

Introduction Seismic stratigraphic techniques have evolved considerably since the underlying principals were first discussed over twenty years ago (e.g. Introduction to seismic data and best workflows for interpreting structures in the data. Self organizing maps (SOM) are especially well suited for improving stratigraphic resolution. Seismic waves have two main types: 1. body waves 2. surface waves 7. 2.

McQuillin , M. Bacon , W. Barclay Springer Netherlands , 1984 - Science - 287 pages When properly applied, seismic stratigraphy provides a powerful foundation for geohistory analysis, helping describe a basin's evolution and the resulting effects upon its spatial and temporal variation in hydrocarbon potential. The concept that primary seismic reflectors parallel bedding planes (time lines) and unconformities forms the basic principle of seismic stratigraphy and may be used to answer some fundamental stratigraphic questions critical to exploration. Jump to: navigation. BASICS OF SEISMIC STRATIGRAPHY I. Differentiates between bright spots, flat spots and dim spots on seismic sections, and explains what causes these direct hydrocarbon indicators. Seismic stratigraphy chronostratigraphically constrains both the sedimentological and fault-mechanical stratigraphy of a basin. The principles of seismic stratigraphy are briefly explained in section 4.2, including the recognition of seismic facies. Introduction to seismic stratigraphy. Seismic stratigraphy. Vail et al., 1977). Given a reasonably noise-free response, seismic wavelength limits the detail which can be seen in two dimensions: vertical, or the thickness of Stratigraphic units; and horizontal, or the areal size of features.
