Estimating subsurface subsidence and compaction

摘要

A method of processing first and second sets of data signals obtained through remotely sensing properties of the same subsurface area at different times comprising the steps of decomposing said first and second data sets into subvolumes of samples and generating subsidence estimates indicating the amount and direction the samples from said first data set need to be translated to obtain a new representation of said first data subvolume that maximally resembles said second subvolume. Preferably, the method further includes the step of derivating said subsidence estimates along the vertical direction in order to generate samples indicating the relative local compaction of the subsurface.
