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.

Seismic imaging for seismic geomorphology beyond the seabed: potentials and challenges

Geological Society, London, Special Publications, 2007
Abstract A successful study of seismic geomorphology depends not only on knowledge of sedimentological, geomorphological principles and the local geological setting, but also on quality of the seismic geomorphological imaging. A thorough understanding of how seismic waves respond to geomorphology of depositional sequences and facies is ...

Seismic geomorphology of a salt‐controlled deltaic depositional system

SEG Technical Program Expanded Abstracts 2007, 2007
For the past decade, volumetric seismic attributes have been used to help define depositional systems (Nissen et al., 1999, Posamentier, 2003). Seismic attributes provide the geometry of paleo-environments, particularly in settings where there is a sharp contrast in the geometry of adjacent systems, for instance in channel belts and associated systems.

The seismicity, geomorphology and structural evolution of the Corinth area of Greece

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1985
Abstract In the eastern Gulf of Corinth, geological structure is closely reflected in the topography. In the 1981 Corinth earthquakes ground deformation accentuated existing geomorphological patterns. We explore the relationship between seismicity and landforms in space and time.

Geomorphology – Understanding the Near-surface Impact on Seismic Data

71st EAGE Conference and Exhibition - Workshops and Fieldtrips, 2009
Surface seismic data are significantly affected by the properties of the near-surface strata. We propose to integrate information extracted from geomorphology into the seismic processing workflow. Topography classification of the elevation and lithology information of satellite imagery allows mapping formation tops, which in turn, provide the basis for

3D seismic geomorphology of fluvial systems

2010
Fluvial sandstones constitute one of the major clastic petroleum reservoir types in many sedimentary basins around the world. This is especially true in the Tertiary basins of Southeast Asia, which display a wide range of fluvial channel reservoir types. This study is based on the analysis of high-resolution, shallow (seabed to ca.

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 ...

Seismic Geomorphology and Evolution of Submarine Channels from the Angolan Continental Margin

Journal of Sedimentary Research, 2007
Abstract Three-dimensional seismic data from the shallow subsurface of the continental margin offshore Angola reveal two end-member morphological styles of submarine channel: (1) high-gradient, low-sinuosity, narrow channels with gull-winged levees, and (2) lower-gradient, deeply incised systems with moderate- to high-sinuosity ...

Buried Fluvial Channels: 3D-Seismic Geomorphology

1997
Fluvial channels potentially occur within the Quaternary stratigraphy of continental shelves world-wide, as a consequence of repeated glacioeustatic lowerings of relative sea level. Buried channels are well-suited to imaging by 3D-seismic methods due to a combination of contrast with surrounding materials and spatial resolution of their distinctive ...
