1. A method for analyzing a subterranean structure configuration, the method comprising:
obtaining a radial acoustic log at a computing system having one or more processors, the radial acoustic log captured using a radial sensor of an acoustic logging tool deployed within a first structure, the first structure disposed within a second structure in a subterranean environment;
determining, with the one or more processors of the computing system, a radial symmetry using the radial acoustic log; and
determining, with the one or more processors of the computing system, an eccentricity of the first structure relative to the second structure based on the radial symmetry.
