Seismic Surveys
Seismic surveys use reflected sound waves to produce a “CAT scan” of the Earth’s subsurface. Seismic surveys can help locate ground water, are used to investigate locations for landfills, and characterize how an area will shake during an earthquake, but they are primarily used for oil and gas exploration.
The basic principle of all seismic methods is the controlled generation of elastic waves by a seismic source in order to obtain an image of the subsurface. Seismic waves are pulses of strain energy that propagate in solids and fluids.
There are three basic types of seismic technologies used to help explore for oil and gas –
- 2D Seismic
- 3D Seismic
- 4D Seismic
