A problem of automation of P- and S-wave first-arrival time evaluation for wave sonic logs has been considered. Opportunity to apply the statistical method used for seismic wave first-arrival time evaluation based on the Akaike criterion for processing of the wave sonic logs has been evaluated. A modification of the method to replace the variance calculation with a Hilbert transform modulus squared one – which can reduce the calculation time considerably – has been proposed.
