dooseis

Dooseis is a term used in seismic exploration to refer to a seismic source that is a single, isolated seismic shot. This contrasts with a "swarm" of shots, which would be multiple sources fired in close succession or in a coordinated manner. In the context of seismic surveys, a dooseis is essentially a single detonation or energy release designed to generate seismic waves that travel through the earth and are recorded by geophones or other seismic sensors. The term is not widely used in academic literature but appears in some industry contexts.

The purpose of a dooseis is to create a discrete seismic event that can be analyzed to understand the subsurface geology. By recording the arrival times and characteristics of the seismic waves, geophysicists can infer properties of the rock layers, such as their thickness, composition, and structure. This information is crucial for identifying potential hydrocarbon reservoirs, understanding geological hazards, and conducting various types of earth science research. The isolation of the shot in a dooseis allows for a clear, unambiguous seismic response to be generated and recorded, which can be advantageous in certain survey designs or for specific types of analysis.
