I am QC-ing some old wells which are logged with Russian logging technologies.
it is challenging for me to understand some of the log types.
I know AK is sonic log (equivalent to DT
But I am not sure what AKA1, AKA2, AKLA.
The log unit for AKA1 and AKA2 are in "V" and the unit for AKLA is not specified.
Could you please help me understand what type of logs these are
