A Universal Simultaneous Shooting Technique

A-04 A UNIVERSAL SIMULTANEOUS SHOOTING TECHNIQUE ROB DE KOK and DIANA GILLESPIE 1 Summary A novel method for the simultaneous recording of seismic data from two or more sources is presented. The coding for the different sources consists of the introduction of either polarity or time delay changes in the field. Separation is achieved through polarity decoding followed by averaging and/or interpolation during processing. For purposes of averaging not only dedicated techniques but also standard processes such as stacking and migration can be relied on. The method is applicable to all possible types of sources and has no restriction as
