Reflection seismology, more commonly referred to as "seismic reflection" or abbreviated to "seismic" within the hydrocarbon industry, is used by petroleum geologists and geophysicists to map and interpret potential petroleum reservoirs. The size and scale of seismic surveys has increased alongside the significant increases in computer power ...
His theoretical work on the form of seismograms and their application (e.g., seismic tomography) has contributed to the study of the Earth's mantle, particularly in Australia. He has developed comprehensive models of propagation velocities of seismic waves that serve as a basis for determining the epicenter of an earthquake , including the ...
Depth conversion is an important step of the seismic reflection method, which converts the acoustic wave travel time to actual depth, based on the acoustic velocity of subsurface medium (sediments, rocks, water). Depth conversion integrates several sources of information about the subsurface velocity to derive a three-dimensional velocity model:
Seismic data is sorted by common midpoint and then corrected for normal moveout. In reflection seismology, normal moveout (NMO) describes the effect that the distance between a seismic source and a receiver (the offset) has on the arrival time of a reflection in the form of an increase of time with offset.

On June 4, 1971, the Geophysical Society of Oklahoma city erected a monument in the front lawn of Belle Isle Library, recording how in 1921 Karcher and his team recorded their first seismic data, and "proved the validity of the reflection seismograph as a useful tool in the search for oil." [9]
Modern seismic reflection surveys are designed and acquired in such a way that the same point on the subsurface is sampled multiple times, with each sample having a different source and receiver location. The seismic data is then carefully processed to preserve seismic amplitudes and accurately determine the spatial coordinates of each sample.
In reflection seismology, a seismic attribute is a quantity extracted or derived from seismic data that can be analysed in order to enhance information that might be more subtle in a traditional seismic image, leading to a better geological or geophysical interpretation of the data. [1]
The term Seismic stratigraphy was introduced in 1977 by Vail [2] as an integrated stratigraphic and sedimentologic technique to interpret seismic reflection data for stratigraphic correlation and to predict depositional environments and lithology. This technique was initially employed for petroleum exploration and subsequently evolved into ...
