This study used the well-log data belonging to
two wells in the Thrace region drilled by the Turkish Petroleum Company (TPAO).
A scale function was created from the correlation of sonic and resistivity logs
in only one of these wells and the non-linear equation it defined was obtained
to derive a pseudo velocity log. With the aid of this equation, a pseudo
velocity log was derived for the second well drilled in the area using only
resistivity log values. Additionally the % error values were calculated for
both wells and the similarities between them investigated.

The true sonic logs and derived pseudo velocity
logs from both wells were compared in the study. For both wells, the logs were
observed to be similar. This study reveals that for any area with the aid of
the non-linear equation based on the correlation between sonic and resistivity
logs taken from one well, pseudo velocity logs can be derived using only
resistivity log values for other wells in the region without requiring new
sonic log measurements.
