Meddy image GOLR012. Regional Project

VSA Author: Richard Hobbs
Scenes: 1
Interpretations: 1
Date Created: 2010-03-31

Profile shows a cross-section though an anti-cyclonic eddy of warm, saline Mediterranean water formed in cooler, fresher North Atlantic water in the Gulf of Cadiz to the south of Cape St. Vincent, a so-called "Meddy". The reflections are largely determined by the short wavelength changes in temperature with depth. The strong reflectivity over the top of the Meddy is formed by alternat...

Visualising seismic data in 3D - Gulf of Mexico 1, West Cameron 1 Regional Project

VSA Author: Alan Roberts
Scenes: 0
Interpretations: 0
Date Created: 2010-03-05

This image shows two seismic probes, within the same 3D data volume, plus an interpreted horizon surface. The probe on the left is a variable amplitude display and normal fault traces can be seen on both vertical surfaces and on the horizontal time-slice. The probe on the right is a coherency display and the fault traces are particularly clear on the horizontal upper surface. The inte...

Scenes: 0
Interpretations: 0
Date Created: 2010-06-06

Plan view of small arcuate slump scars that characterize the inner face of levees bounding a Pleistocene deep-water channel in approximately 2000 m of water in the northeastern Gulf of Mexico. This channel lies approximately 80 m below the sea floor and was characterized by flows from right to left. Colors indicate time structure, with warm colors representing bathymetric highs and co...

Scenes: 1
Interpretations: 1
Date Created: 2010-01-28

This is a dip attribute map created from merged bathymetric data from the northern art of the Sinu accretionary prism, offshore Colombia. The northern part of the image shows depositional features of the lower Magdalena fan. See Survey for details of the source etc of this image. The associated scene is 2D seismic profile across the margin.

All Namibian Margin Balancing - overview Interpretation

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

This interpreted section shows arbitrary picks and designation of units in the extensional domain, and two markers in the contractional domain. Note that the vertical exaggeration is approximately 7:1 . assuming a mean seismic velocity of 2.7 km/s. See the scenes for this image for further comments.

Bight Basin, scene 3 -interpretation Interpretation

Date Created: 2010-10-29

Interpretation of the seismic image, showing a laccolith and an associated volcano.

FIRE 2 interpretation Interpretation

VSA Author: Taija Torvela
Date Created: 2010-01-12

Interpretation by Nironen et al. (2006). The FIRE 2 (and 2A) deep seismic reflection profiles were designed to study the relationships between the arc complexes of western and southern Finland and their internal structures (see docs & links for a location map). FIRE 2 begins in the central part of the arc complex of western Finland in the north, within the Central Finland Granitoid Co...

3D perspective of spectral decomposition of interpreted horizon. See associated scenes.

Reef platform and outliers, time structure map Regional Project

VSA Author: Henry Posamentier
Scenes: 3
Interpretations: 0
Date Created: 2010-06-06

Time structure map of the surface bounding the top of the Kujung 1 carbonate deposits. The southern part of the study area is characterized by a broad carbonate platform topped by reefs ranging from 3 to 5 km diameter. Outlier buildups up to 8 km in diameter are observed to the north and northwest. Image presented at the "Frontiers of Seismic Geomorphology" showcase held at the Geol...

Scenes: 0
Interpretations: 1
Date Created: 2009-09-20

This seismic line was calibrated by wells Czlopa 1, Czlopa 2 and Czlopa 3 that were correlated using tie lines of the same survey. For all these wells check-shot data are available facilitating good well-to-seismic ties. Published in Krzywiec (2006; see docs & links).

DRUM filtered 2 Regional Project

VSA Author: Taija Torvela
Scenes: 0
Interpretations: 0
Date Created: 2016-05-02

The original seismic is filtered with 8x8 (trace x sample) dip-steered median filter of Opendtect with a maximum seismic dip of c. 40 degrees, this reduces 1D noise and also removes some steep coherent noise while enhancing signal continuity. This filtered seismic is then overlain with the cosine of phase attribute of the dip-steered data, in order to enhance the signal geometries fur...

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...

Seismic stratigraphy for post Messinian section Interpretation

VSA Author: Rob Butler
Date Created: 2018-04-17

This simple interpretation identifies strata relationships in the younger section and interprets them with respect to deformation of the top-Messinian (M) reflector and the younger depositional events. Note that there is a gradational passage out from the syn-kinematic to post-kinematic section ...

Architecture and image characteristics of a normal fault - Inner Moray Firth Interpretation

VSA Author: Rob Butler
Date Created: 2015-01-28

These interpretations display a correlation of units across the fault zone - which has synthetic splays and an offset relay structure at depth. The growth strata are chiefly of upper Jurassic in age - with the deepest identified unit par of the middle Jurassic (locally) pre-rift stratigraphy. The annotations identify some "typical" characteristics of faults imaged in 2D seismic data. ...
