Abstract
A method for identifying a shape of a borehole may comprise disposing a measurement assembly into the borehole, transmitting a pressure pulse from the at least one transducer, recording the echo with the at least one transducer producing data points based at least in part on the echo to determine a distance from an inner wall of the borehole to the measurement assembly; performing a kurtosis on the data points; comparing a result of the kurtosis to a pre-determined threshold; and producing one or more repositioning results based at least in part on the comparing the result of the kurtosis to the pre-determined threshold. A system may comprise a measurement assembly which may include at least one transducer connected to the measurement assembly and an information handling system.
