Abstract
A new technique is developed for generating a short seismic pulse from the bubble pulses which are radiated by an air‐gun. The new technique, which is useful in well velocity surveys and vertical seismic profiling, can be implemented by firing a single air‐gun several times at the same depth but with different chamber pressures.A record obtained by this procedure from a well‐geophone clamped at a depth of 2450 m gave a maximum peak‐to‐peak amplitude within the first 100 ms of the effective seismic pulse at least ten times any later peak‐to‐peak amplitude.Keywords
