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 ...
Bottom simulating reflectors (BSRs) are, on seismic reflection profiles, shallow seismic reflection events, characterized by their reflection geometry similar to seafloor bathymetry. [1]. They have, however, the opposite reflection polarity to the seabed reflection, [1] and frequently intersect the primary reflections. [2]
Whenever a new social game creator burst onto the scene with promises of "shaking up the status quo," it's tough not respond with a bit of skepticism. Perhaps it's cynicism. Maybe it's even the ...
A seismic sequence is defined as the stratigraphic interval between two consecutive sequence boundaries, representing two marine regression events with a marine transgression event at the middle. Thus a seismic sequence is further subdivided with a basal unit of regressive systems tract, a transgressive systems tract at the middle, and a ...
An air gun seismic source (30 litre) A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys. A seismic source can be simple, such as dynamite, or it can use more sophisticated technology, such as a specialized air gun.

In comparison to the typical seismic reflection survey, which is restricted to relatively small incidence angles due to the limited offsets between source and receiver, wide-angle reflection and refraction (WARR) data are acquired with long offsets, allowing the recording of both refracted and wide-angle reflection arrivals.
