53847520, Jan 24, 1995

Filed:

Apr 6, 1993

Appl. No.:

8/043267

Inventors:

Richard E. Duren - Spring TX
Kenneth D. Andersen - Kingwood TX

Assignee:

Exxon Production Research Company - Houston TX

International Classification:

G01V 128
G01V 136

US Classification:

367 38

Abstract:

A method of correcting a seismic pulse waveform for use in deconvolution of reflected pulse data. The source pulse waveform is measured by a hydrophone positioned vertically beneath the acoustic source. The phase error is calculated based on the depth of the source and the depth of the measuring hydrophone. The calculated error is subtracted from the phase spectrum of the measured waveform. The resulting waveform provides an accurate representation of the true far field waveform, leading to an improved expression of the waveform actually incident upon the marine floor.
