NS 2.6 Near-surface velocity gradients and their effect on shallow reflection data
Near-surface velocity gradients can be large enough to inhibit normal moveout corrections on a single pass of a complete shallow velocity function during routine shallow seismic reflection processing flows. Stretch artifacts that are the result of inversion and compression within the highest rate of velocity change portion of the shot gather can stack coherently on CMP sections. The constant ve...
متن کاملThe Effects of Thin, Near-surface Layers on Seismic Signals
Signals generated by moving tracked vehicles can be significantly affected by near-surface materials including pavements, compacted soils, shallow bed rock, and the water table. The ways that seismic signals depend on these surface layers are examined by analyzing impulsive point forces applied at the earth-air interface. Fields are calculated using a plane layered frequency domain wavenumber m...
متن کاملNear-surface VSP surveys using the seismic cone penetrometer
We have found that high-quality vertical seismic profile (VSP) data can be collected for near-surface applications using the seismic cone penetrometer. Conemounted accelerometers are used as the VSP receivers, and a sledgehammer against the cone truck baseplate is used as a source. This technique eliminates the need to drill a borehole, thereby reducing the cost of the survey, and results in a ...
متن کاملApplication of Near Surface Mounted (NSM) technique for Seismic Retrofitting of Heritage Buildings
The high vulnerability of the cultural buildings due to seismic actions urged researchers to retrofit them using reversible and compatible techniques. The application of fiber reinforced polymer (FRP) for enhancing the structural behavior of masonry buildings, under seismic actions, has been studied by many researchers. The near-surface mounting (NSM) technique is a relatively new retrofitting ...
متن کاملHigh-resolution seismic reflection survey near SPR surface collapse feature at Weeks Island, Louisiana
Shallow high resolution 2-D and 3-D seismic reflection techniques are assisting in the subsurface delineation of a surface collapsc feature (sinkhole) at Weeks Island. Louisiana. Seismic reflection surveys were conducted in March 1994. Data from walkaway noise tests were used to assist selection of field recording parameters. The top of the salt dome is about 180 ft below ground surface at the ...
