Adaptive Sweep Method and Device for Seismic Exploration

摘要

Controller and method for adapting a frequency sweep for a vibro-acoustic source element that is configured to generate acoustic waves during a seismic survey. The method includes driving (800) a seismic source element to generate a current frequency sweep; recording (802) seismic data with plural seismic sensors in response to the current frequency sweep; selecting (804), during the seismic survey, a data subset of the seismic data, wherein the data subset has a size less than 10% of the seismic data; calculating (806) with a processing device an attribute based on the data subset; and calculating (808) a new frequency sweep based on the attribute
