We examine the conventional methodology for tying wells to processed seismic data and show why this methodology fails to allow for reliable interpretation of the seismic data for stratigraphy. We demonstrate an alternative methodology that makes the tie without the use of synthetic seismograms, but at the price of measuring the seismic source signature, the cost of such measurements being about...

APPROACH In July-August 1998 aboard the USNS Bowditch, we collected sediment cores, CTDs and XBTs, 3.5 kHz subbottom profiles, and high-resolution 48-channel seismic profiles. This survey covered as much of the Gulf as possible given the restrictions that reefs, oil fields and territorial limits have on ship operations. The approach was to seismically map Neogene stratigraphy and tie this struc...

Seismic reflector interfaces in the subsurface are typically idealized as zero-order discontinuities. According to this model, the Earth’s subsurface is represented by a spiky reflection coefficient sequence for which deconvolution methods have been derived. However, multiscale analysis on sedimentary basins reveals the existence of accumulation of varying-order singularities in the subsurface....

Shallow seismic reflection marine profiles were collected in the area of Balaton Lake in Hungary using high frequency boomer techniques, in order to get information about the stratigraphy of the sedimentary layers. The noise in these shallow marine seismic reflection data is analyzed, and a series of traditional seismic data processing techniques is applied to improve the S/N ratio and coherenc...

One of the key issues associated with the understanding of large scale impacts is how the observable complex crater structural features (e.g., central peaks and pits, flat floors, ring shaped ridges and depressions, tratigraphic modifications, and faults) relate to the impactor's parameters (e.g., radius, velocity, and density) and the nonobservable transient crater measures (e.g., depth of pen...

Re ection patterns play an important role in seismic sequence stratigraphy, therefore making their quantitative description essential for the construction and validation of sequence stratigraphic models from seismic data. The characteristics of a seismic re ection pattern can be elicited from the data by representing the data as a joint function of time and frequency. Developments in the eld of...

Seismic coherence is widely used in seismic interpretation and reservoir characterization to highlight (with low values) faults and stratigraphic features from a seismic image. A coherence image can be computed from the eigenvalues of conventional structure tenors, which are outer products of gradients of a seismic image. I have developed a simple but effective method to improve such a coherenc...
