What is seismic data processing?

Seismic Data Processing. GEOS 469/569 – Spring 2006. ∎ GEOS 469/569 is a mix of digital filtering theory and. practical applications of digital techniques to assemble. and enhance images of subsurface geology.

What is 3D seismic data acquisition?

A set of numerous closely-spaced seismic lines that provide a high spatially sampled measure of subsurface reflectivity. In particular, 3D seismic data provide detailed information about fault distribution and subsurface structures.

What types of spreading are used in seismic acquisition?

The geometrical pattern of groups of geophones relative to the seismic source. The output from a single shot is recorded simultaneously by the spread during seismic acquisition. Common spread geometries include in-line offset, L-spread, split-spread and T-spread.

What is a seismic line?

Definition: Geophysical measurement used to record acoustic response of seismic sources along a line in order to define seismic properties in a cross section of the earth. Geophysics.

What kind of waves can a seismologist record and study?

Seismic waves travel through and around the Earth and can be recorded with seismometers.

What are seismic waves types?

There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.

What are the different types of seismic data?

There are three types of seismic data: Reflection (including 2-D and 3-D) Shear wave Refraction

Seismic data processing involves the compilation, organization, and conversion of wave signals into a visual map of the areas below the surface of the earth.

What is explosive seismic data?

explosive seismic data. 1. n. [Geophysics] Surface seismic data acquired using an explosive energy source, such as dynamite. See: acquisition , impulsive seismic data , vibratory seismic data.

seismic line. 1. n. [ Geophysics ] A display of seismic data along a line, such as a 2D seismic profile or a profile extracted from a volume of 3D seismic data. A seismic section consists of numerous traces with location given along the x-axis and two-way traveltime or depth along the y-axis.
