Seismic Survey | A vital part of oil and gas exploration

Seismic Surveys are used to produce images of the various rock types and their location beneath the Earth's surface. Seismic information accurately plans the location and size of oil and gas wells, reducing the need for further exploration and minimising environmental impact.

Reflection seismology

Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator, commonly known by the trademark name Vibroseis.

Seismology: Notes: Seismic Waves

Seismic Waves. Waves that propagate through the earth as elastic waves are referred to as seismic waves.There are two broad categories of seismic waves: body waves and surface waves. Body waves - These are elastic waves that propagate through the Earth's interior. In reflection and refraction prospecting, body waves are the source of information used to image the Earth's interior.
