Seismic exploration (reflection and refraction) 2. endobj This velocity After the geology of the area to be studied is … 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. Acquisition of seismic data is the first phase of the three main phases in the seismic industry, which are: 1. Seismic prospecting has become the most valuable technique to reduce exploration risk of being unsuccessful in locating a prospect. Seismic exploration primarily makes use of compressional waves (P waves), whose velocities in rocks range from 0.4–0.5 to 7–8 km/sec. seismic-exploration purposes, where measurements are taking place at the surface, the di erent arrivals of direct waves, re ected waves and refracted/head waves are discussed.
