    basalt layer seismic processing canada. Mar 16 2018 · Abstract Imaging below the basalt for hydrocarbon exploration is a global problem because of poor penetration and significant loss of seismic energy due to scattering attenuation absorption and modeconversion when the seismic waves encounter a highly heterogeneous and rugose basalt layer The conventional short

  • Sub-basalt imaging problems and the application of,

    01.12.2001· In this situation, standard seismic processing is often unable to resolve the structure beneath such basalt layers. For this reason, alternative techniques are sought to improve imaging of sub-basalt strata and aid the delineation of the bottom basalt. Acquisition techniques, developed for this purpose, include two-ship shooting, which produces very long offset data

  • Experience with the issue of seismic surveying over basalts

    basalt layers is very complex and conventional reflection seismic surveying is less effective, producing sub-surface images of variable quality. Figure 1 and Figure 2 present two shot gathers and one 2D seismic stack section from Peabody’s North Goonyella Mine. The basalt is located at the right end of the section. The data clearly shows that the basalt-cover seriously affects the
