Abstract

A twelve channel vertical seismic cable has been constructed, tested, and a full scale 3-D acquisition program in the Gulf of Mexico has been completed. The basic vertical cable concept, in the marine environment, is to deploy the receivers vertically instead of horizontally as is the usual case. The vertical cable had its genesis in walkaway Vertical Seismic Profile (VSP) with the important difference that it constitutes VSP without, the borehole, the tube waves or expensive standby rig time. Construction of a vertical cable requires a different set of ocean engineering requirements than does astreamer. The oil filled jacket is replaced with a high-strength Kevlar stress member surrounding the conductors. The hydrophones are attached to the outside of the Kevlar cable and fairing is attached to the cable to reduce the drag of ocean currents.
