Method for improving coupling with the ground of land based seismic sources

摘要

A process for improving the coupling of seismic sources with the ground by temporary consolidation thereof, consisting essentially in boring one or more injection holes in the vicinity of the successive locations of a seismic profile where it is desired to trigger off a seismic source and injecting into these holes a freezing fluid which freezes the ground and increases its resistance to compression and shearing. The method in particular minimizes the coupling losses at relatively high frequencies.
