Mathematical constraints of Backus averaging

We quantified mathematical constraints of Backus averaging.

 

Our quantification is based on approximation theory, and examines intrinsic approximations of Backus averaging, such as the average of a product expressed as product of averages.

 

Presently, seismologists can quantify the reliability of their interpretation based Backus averaging, which is a ubiquitous method of applied geophysics.
