Inversion, North Sea Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-19

Volcanic geometries - Browse basin Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-19

An interpretation of the volcanic bodies imaged offshore NW Australia. Note relative timing of the sill complex (later) to the volcanic edifies (earlier), as implied by the onlapping post volcano units, which show growth related to the "blister" fold directly above the sill complex....

Interpreting a deepwater thrust system: offshore Namibia Scene

VSA Author: Rob Butler
Interpretations: 1
Date Created: 2021-02-18

This image can be used as a simple interpretation exercise in structural geology. There is a debrief pdf in the doc and links that goes through an interpretation workflow - leading to the associated interpretation uploaded here. The aim here is to build an interpretation of stratigraphic horizons through a thrust belt. Three horizon are identified. trace these through the array of th...

Interpreting a deepwater thrust system, offshore Namibia Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-18

An interpretation of a deepwater thrust belt. See associated scene if you'd like to use this to run a simple seismic interpretation exercise. The clean "scene" has, via its docs and links, a pdf that goes through an interpretation workflow.

Contourite drift, Western Rockall margin Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-11

A contourite drift, showing internal architecture indicative of apparent (in this orientation) up-slope migration of the sediment body. Significant active deep-marine currents are recorded for this part of the NE Atlantic.

Detail of basal surface of two slope channels, with cross sections of the levees Scene

VSA Author: Zoltan Sylvester
Organization: Shell
Interpretations: 0
Date Created: 2010-05-24

This is a 3D view of the basal surface of two slope channel-levee systems (see parent regional project), draped with seismic amplitude (red = high amplitude, blue = low amplitude). The channel to the right widens as it enters a slide scar. Thicker levees develop in this area. Seismic data is courtesy of CGGVeritas. Image presented at the "Frontiers of Seismic Geomorphology" showcase h...

Faults and graben (less VE version), offshore Tunisia Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-06

A rather better representation of faults and graben structure, with less vertical exaggeration. See the alternate interpretation for comparison.

Seismic stratigraphy exercise Interpretation

VSA Author: Julien Moreau
Date Created: 2013-09-12

Correction of a seismic interpretation exercise I gave. The interpretation is uniquely based on reflection termination picking which indicate bounding surfaces. No model is involved. Colours between two successive bounding surfaces have no genetic meaning they only give a sort of chronology through the repetition of a colour cycle (blue, pink, green,yellow) . The objective of the exer...

VSA Author: Rob Butler
Interpretations: 1
Date Created: 2021-02-09

Detail of clinoforms seen at the shelf-break, offshore Morocco. These image links to an exercise in seismic stratigraphy interpretation. See linked interpretation for ... the interpretation!

Closely spaced faults - and imaging issues, offshore NW Morocco Interpretation

VSA Author: Rob Butler
Date Created: 2021-02-01

This and associated interpretation (annotated) shows array of "synthetic" normal faults offsetting high-frequrency reflectors (probable contourites).

Basal grooves, another composite image Scene

VSA Author: Henry Posamentier
Interpretations: 0
Date Created: 2010-06-07

Illuminated horizon with time structure overlain (warm colors indicate bathymetric highs and cool colors indicate bathymetric lows), with associated transverse seismic amplitude section, illustrating deep erosional scour at the base of a mass-transport deposit.

A high resolution version of the thrust belt, Namibia Scene

VSA Author: Rob Butler
Interpretations: 0
Date Created: 2009-08-17

High quality seismic reflection data reveal thrust and fold structural geometry offshore Namibia. The lack of image distortion and amplitude variations associated with structures indicates a generally simple seismic velocity structure that is a function of depth rather than stratigraphy. Note the preservation of amplitude up to the thrust cut-offs, with almost no loss in data quality....
