Abstract

A

By direction shooting is understood a method of continuous seismic profiling with shots distributed along the total length of the geophone spread, the shots being fired either with time delays in the field, or, recorded singly on magnetizable material and composited with time‐delays. Therewith, the subsurface can be probed in any desired direction, enhancing reflections from these directions and attenuating or eliminating events from all other directions. For each reflection, the correct delay can be found by a simple procedure from a single trial record.

A complete description of the method is given, inclusive of all procedures and proofs pertaining to it. Synthetic examples and field examples illustrate the efficiency of the method and its resolving power.
