SUMMARY 2-D scale models and synthetic seismograms have been used to study diffraction artifacts and interpretation pitfalls on seismic profiles over two classes of simple-shaped structures: a vertical fault model and a rectangular mound model. The f

Guided seismic waves are generated at lateral discontinuities in coal seams as an integral part of the mechanics of scattering downgoing body waves from a surface energy source. Numerical and laboratory model studies undertaken for both thin and thic

Hydrocarbon reservoirs sometimes occur within low velocity channels, thus forming potential seismic waveguides. The waveguide might be excited at its discontinuities (faults) by seismic waves travelling downward from a surface source. Given that a wa

SUMMARY This paper presents a modified form of polarization position correlation (PPC) operator which can be used to separate P- and S-waves in a multicomponent seismic profile. the essence of the method (in seeking S-wave extinction) is to form a do

A multicomponent seismic laboratory experiment was conducted to examine the seismic signature of a simulated ore-body structure. The data were processed using a new form of controlled direction reception (CDR) filter, which operates in tau-p-polarisa
