Seismic shot hole drilling is a critical part of Oil Exploration programs. The process consists of drilling a series of vertical holes, up to 90 feet deep, at approximately 200 yard intervals. The holes are then loaded with explosives and detonated in a precisely controlled sequence. Geophones are placed to read the rebound energy from a detonation and the data is processed by the geophysical company at a later date to interpret the structural formation. Dynamite is one of the two primary energy sources used for seismic programs.
