1. A method comprising:
identifying a set of values included in a set of wellbore log data, the set of values associated with material characteristics of a wellbore;
generating a first spatial domain function associated with the set of values when preparing to convert the first spatial domain function into a frequency domain function based on a neural operator;
converting the first spatial domain function into the frequency domain function based on the neural operator;
converting the frequency domain function into a second spatial domain function; and
identifying the material characteristics of the wellbore based on application of the second spatial domain function.
