METHOD AND SYSTEM FOR SIMULTANEOUS ACQUISITION OF PRESSURE AND PRESSURE DERIVATIVE DATA WITH GHOST DIVERSITY

摘要

A marine streamer spread (800) for acquiring seismic data, the spread including a streamer (801) having a first portion (808) and a second portion (810); the first portion (808) including both first pressure sensors (902) and pressure derivative sensors (904) for acquiring the seismic data; and the second portion (810) including second pressure sensors (902). The first portion (808) imparts ghost diversity to the seismic data by having a variable-depth profile and the pressure derivative sensors (904) impart polarity diversity to the seismic data.
