Curvature for visualization of seismic geomorphology
Geological Society, London, Special Publications, 2007Abstract We illustrate the use of curvature attributes for defining stratigraphic features of interest on horizons mapped in three-dimensional seismic data. Curvature is a two-dimensional property of a curve that quantifies how much the curve deviates from a straight line.

Abstract Globally, Lower Cretaceous carbonate platforms form important hydrocarbon reservoirs. An exceptional seismic dataset allowed us to examine controls on the stratigraphy, seismic geomorphology, facies architecture and along-strike variability of a Lower Cretaceous platform.

Seismic Geomorphology and Connectivity of Deepwater Reservoirs
SPE Reservoir Evaluation & Engineering, 2006Summary Assessing reservoir connectivity and permeability heterogeneity is essential for predicting reservoir performance. Because reservoirs are 3D entities, there is little value in trying to predict reservoir connectivity on the basis of 2D data such as geological sections or maps.

Applied Mechanics and Materials, 2011
Seismic stratigraphy and seismic geomorphology provides an indication of a carbonate platform’s internal and external architecture. High quality 3D seismic data integrated with wireline logs and core materials furthers detailed depositional element analysis, lithology prediction and diagenetic modification of the stratigraphic section, which help to ...

Proceedings, 2014
The application of seismic stratigraphy and geomorphology hinges on the identification of reflection patterns, and consequently the interpreter’s ability to leverage those patterns to predict suburface lithology. Predicting lithology prior to drilling centers on seismic pattern recognition, a process that involves the iterative interpretation of ...

Some considerations concerning seismic geomorphology and paleoseismology
Tectonophysics, 2005Abstract Seismic geomorphology studies landforms which developed in connection with earthquakes. Among them, two different end members may be distinguished: 1) seismo-tectonic landforms, including surface faults and fractures, land uplift and subsidence at different scales, surface bulges, elongate ridges, and any other permanent ground deformations ...

Geomorphology and seismic risk
Earth-Science Reviews, 1991Abstract The author analyses the contributions provided by geomorphology in studies suited to the assessment of seismic risk: this is defined as function of the seismic hazard, of the seismic susceptibility, and of the vulnerability. The geomorphological studies applicable to seismic risk assessment can be divided into two sectors: (a) morpho ...

Geomorphological controls on seismic recordings in volcanic areas
2020<p>In volcanoes, topography, shallow heterogeneity, and even shallow morphology can substantially modify seismic coda signals. Coda waves are an essential tool to monitor eruption dynamics and model volcanic structures jointly and independently from velocity anomalies: it is thus fundamental to test their spatial sensitivity to ...

Fluvial seismic geomorphology: a view from the surface
Geological Society, London, Special Publications, 2007Abstract Three-dimensional seismic data enable geoscientists to image the stratigraphic record along selected stratal or time slices. These slices provide detailed images of the planform geometry of ancient depositional systems and environments.
