Processing and interpretation of reflection seismic data from a basalt-covered area Significant parts of the Norwegian Sea and adjacent northeast Atlantic Ocean have a basalt cover at shallow depth. In much of this area there are prospective petroleum resources both beneath and intercalated with the basalt.Seismic properties of layer 2 basalts | Geophysical,,01-02-1997· In this paper the physical properties of oceanic layer 2 basalts are examined with the emphasis on microcrack porosity and alteration-related changes in physical properties. Over 160 core samples from some of the more significant Deep Sea Drilling Project/Ocean Drilling Program holes, including 417D, 418A, 504B and 801C are included in the present investigation.Seismic wave propagation through an extrusive basalt,,01-04-2016· Layers of basalt flows within sedimentary successions (e.g. in the Faeroe-Shetland Basin) cause complex scattering and attenuation of seismic waves during seismic exploration surveys. Extrusive basaltic sequences are highly heterogeneous and contain strong impedance contrasts between higher velocity crystalline flow cores (∼6 km s-1) and the lower velocity fragmented and weathered flow

This study demonstrates that appropriate acquisition and processing of marine seismic data from hydrophone,Coal seismic surveying over near-surface basalts,,sub-basalt imaging problem. PSDM is a seismic imaging processing technique often used for imaging complex structures with strong lateral velocity variation such as sub-salt imaging (Yilmaz, 2001). The use of this technique for sub-basalt imaging has been demonstrated by a

Enhancing Sub Basalt Imaging Using Depth Domain Processing

Processing of 2D long offset Seismic Reflection data for sub basalt Imaging still remains a challenge for the Processing Geophysicists. So far there is no commercial processing solution for meaningful imaging below basalt. Time domain processing has its limitations to process reflection events which are hyperbolic in nature. With careful,Sub-basalt imaging problems and the application of,,01-12-2001· In the presence of thick, laterally extensive basalt layers, seismic reflection sections are typified by a high amplitude top basalt reflector and the absence of base-basalt and sub-basalt events. From our tests, varying layer thickness and source frequency, a synthetic 2-D fractal model, which produces seismic similar to real sub-basalt seismic, has been created.Sub-basalt Imaging Using Broadside CSEM,below a basalt layer. However, due to shape irregularities and het erogeneities with high velocity contrasts around and within the basalts, it can be challenging for seismic processing to image the base of the basaltic layer and details of what is below .
