Abstract

This is a report of the SEG Subcommittee on Polarity Standards in exploration seismic recording. A Polarity Standard is recommended for analog and digital representations of seismic impulse signals. A four-bit polarity code is proposed to define: (1) the polarity convention for impulse-source systems; and (2) the relative polarity between a swept-frequency pilot signal and the recorded seismic data for vibratory-source systems. Polarity conventions are to be demonstrated by field tests and confirmed by computer analysis.
