	Seismic interpretation of H-SENSE data and sub-bottom characterization using chirp sonar technology (Site not responding. Last check: 2007-11-02)
		This is done by interpreting the seismic data and with the use of derivations from the reflection coefficient generated by the sub-bottom profiler.
		The results of the seismic interpretation of the sediment thickness and sub-bottom characterizing are presented as maps using standard contouring software to interpolate between the traverse line pints.
		The results are hard to interpret as the video delay function had to be adjusted very often and probably the reflectors are immigrated requiring specialist software to correct for distortions as a result of the steep slopes.

	USC Sequence Stratigraphy: Exercise in Seismic Interpretation using synthetic wiggle trace from well tied to seismic (Site not responding. Last check: 2007-11-02)
		These inferences and sequence stratigraphic analyses are often based on seismic cross-sections, well logs and outcrop studies of sedimentary rocks and are used to predict the continuity and extent of their lithology.
		Usually seismic provides the regional control on the geometries of sequences and wells are used to determine the lithology of these geometries.

		The three younger units are interpreted from the SOCAL wells to range from marine to non-marine and progress in age from Neogene to late Pleistocene.

	GCPitfalls in 3-D Seismic Interpretation, by Alistair R. Brown, #40146 (2005).
		Seismic section with dry hole and good well penetrate high amplitudes, but only the latter with red-over blue (trough-over-peak) is representative of low-impedance prospective sand.
		I believe that every seismic interpreter, with an objective beyond structure, has the responsibility to determine or verify the phase and polarity of his or her data.
		As interpreters we must be continuously learning to improve our understanding of geophysics and our skills in using the workstation.

	LAB 5: Subsurface Information from Interpretation of Seismic Record Section (Site not responding. Last check: 2007-11-02)
		Structural interpretation is based on the changes in the arrival times of reflected wavelets from a particular seismic interface.
		Zones or horizons of interest on the seismic record sections can be defined by correlating actual well data to the seismic record by use of synthetic seismograms and/or well velocity information.
		It is important to realize that seismic reflections do not always necessarily arise from the tops and bottoms of formations but often from surfaces within a formation, i.e.

	Interpretation of Incised Valleys Using New 3D Seismic Techniques: A Case History Using Spectral Decomposition and ...
		New 3D seismic interpretation techniques such as spectral decomposition and coherency have been shown to enhance interpretation of stratigraphic features in Tertiary, poorly lithified rocks, but their use has not been as well documented on older, more consolidated sediments.
		The seismic cross-section illustrates the difficulty of interpreting the Red Fork incised valley using traditional seismic interpretation techniques (auto-picking horizons, amplitude mapping, isochron mapping etc.).
		Interpretations of borehole, spectral decomposition and coherency data were combined in the geologic interpretation of seismic cross-sections.

	The University of Melbourne - 625-304 Applied Geophysics - Seismic
		Seismic exploration is the conduit for most expenditure in geophysical exploration by a wide margin.
		This is a response to the recognition of the highly effective way seismic data images the geometry of subsurface rocks, especially in sedimentary provinces, over almost all scales and in most environments on and off shore.
		Processing of seismic data enables the recognition of even details of past depositional environments from the features preserved as differences in the elastic properties of rocks.

		This greatly reduces the time involved in generating seismic interpretations, in that interpretations no longer need to be digitized from paper records.
		However to accurately interpret the geology of an area correlations must be made between the surficial sediment characteristics acquired by sidescan-sonar and groundtruth techniques, and the underlying structure acquired through use of seismic reflection techniques.
		Two components of this interpretation are displayed in the figures to the right: the surficial sediment distribution, and the thickness of Holocene sediment based on seismic interpretations.

	Schlumberger, Petrel Seismic Interpretation
		The Seismic Interpretation module combines the simplicity of interpreting in 2D with the QC advantages that only 3D can bring.
		You gain the unique advantage of working in a strong and mature modeling environment as you rapidly interpret seismic data and compare the results with all other data residing in your project.
		2D seismic interpretation demands a very flexible and dynamic project data management structure in order to cope with the size and number of lines involved in traditional 2D interpretation workflows.

	Seismic Interpretation 1
		Seismic interpretation, whether for hydrocarbon exploration or geotechnical studies, is the determination of the geological significance of seismic data.
		Synthetic seismograms are artificial seismic traces used to establish correlations between local stratigraphy and seismic reflections.
		In principle, the horizontal resolution of migrated seismic data is equal to the spatial Nyquist wavenumber (i.e., twice the CMP trace spacing - typically about 10 m).

		Interpretation will emphasise the evaluation of the seismic data quality in the development of a consistent and believable integrated sedimentological and reservoir model.
