Abstract
Abstract Common depth point seismic prospecting is accomplished by sequentially producing seismic waves at transmitting locations spaced apart the distance A, and detecting resulting seismic waves at a first plurality of detecting locations along the traverse spaced apart a distance A from the transmitting location corresponding thereto and a second plurality of transmitting locations spaced apart a distance 2A, the second plurality of detecting locations beginning at the end of the first plurality.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
240 words
In the method of reflection seismography wherein there are produced a plurality of seismic records having events thereon resulting from seismic waves reflected from common reflecting locations on subsurface reflecting horizons and wherein such seismic records are summed to enhance reflection events, the improved method of producing such seismic records comprising: a. locating along a seismic traverse a plurality of seismic wave transmitting and detecting stations evenly spaced apart by a distance A; b. producing a first seismic disturbance at a first transmitting location located on a seismic traverse; c. detecting resulting seismic waves at a first plurality of first detecting locations linearly spaced apart a distance A along said traverse beginning at a distance A from said transmitting location, and at a second detecting location spaced apart a distance 2A along said traverse, said second detecting locations being located on the opposite side of said first detecting locations from said first transmitting location; d. recording the detected signals to produce a first seismic record; e. producing another seismic disturbance at another transmitting location spaced a distance 2A from the preceding transmitting location; f. detecting seismic waves resulting from another seismic disturbance at detecting locations corresponding to said first and second detecting locations but moved a distance 2A in the direction of said second seismic disturbance location from said first transmitting location recording the detected signal to produce another seismic record; and g. repetitively repeating steps d, e, and f.

Claim 3
Dependent Claim
21 words
