Seismic Geomorphology and Connectivity of Deepwater Reservoirs

SPE Reservoir Evaluation & Engineering, 2006
Summary 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.

Integration of Seismic Stratigraphy and Seismic Geomorphology for Prediction of Lithology - Applications and Workflows

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 ...

Geomorphology and seismic risk

Earth-Science Reviews, 1991
Abstract 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 ...

Some considerations concerning seismic geomorphology and paleoseismology

Tectonophysics, 2005
Abstract 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 ...

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, 2007
Abstract 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.

Seismic geomorphology-based facies classification

The Leading Edge, 2004
Seismic facies analysis is a powerful, yet largely subjective, methodology for hydrocarbon exploration and development. The term “seismic facies” means different things to different people. For this study, however, seismic facies is defined as a seismic description of depositional facies confined in a seismically thin bed at a normal seismic sampling ...

The use of the refraction-seismic techniques in geomorphology

CATENA, 1976
Summary The portable refraction seismograph provides a useful research tool for determining the characteristics and thickness of surficial waste covers. Several types of instruments are described here. The operation of the portable seismograph and the interpretation of data are discussed including several examples of its use in the field.

Quantitative seismic geomorphology of channel reservoir of the Laizhouwan sag

Global Meeting Abstracts, 2011
This paper documents the application of techniques in seismic geomorphology in quantifying the morphometrics and architecture of a Neogene channel system in Laizhouwan Sag, Bohai Bay Basin, China. The principal goal of our study is to assess the relationship between five morphometric parameters including channel width, meander-belt width, meander ...
