Welltest 103: Acoustic Well Sounder Surveys

While we’re featuring #AWS surveys, who remembers these 10 Point Calipers for reading paper charts? Google doesn’t even seem to know anything about them. They make counting collars easier, and more accurate, as sound waves actually speed up with well depth, thus joint reflections become closer together. Be sure to mark every 10 joints for double-checking chart interpretation and #welltest quality control.
