Elastic parameter estimation

A system comprising:

• a processor;
• memory accessible by the processor;
• and
• processor-executable instructions stored in the memory that are executable to instruct the system to:
• receive information that comprises elastic property information and that comprises sonic data acquired via a tool disposed at a plurality of depths in a bore in a subterranean environment that comprises at least one anisotropic formation;
• process the information to generate processed information wherein the processed information comprises variance information associated with the elastic property information and wherein the processed information comprises velocity information and orientation information associated with the sonic data;
• perform an inversion based at least in part on the processed information;
• and
• output values for elastic parameters based at least in part on the inversion.

One or more computer-readable storage media comprising computer-executable instructions to instruct a system to:

• receive information that comprises elastic property information and that comprises sonic data acquired via a tool disposed at a plurality of depths in a bore in a subterranean environment that comprises at least one anisotropic formation;
• process the information to generate processed information wherein the processed information comprises variance information associated with the elastic property information and wherein the processed information comprises velocity information and orientation information associated with the sonic data;
• perform an inversion based at least in part on the processed information;
• and
• output values for elastic parameters based at least in part on the inversion
