Ask them how much they utilize the descriptions (ie the non-mathematical materials) in correlation.
How do you know stratigraphers? Are you in the oil patch?
(Also it's a common joke within the geological community that we went into geology because we weren't great with the math needed for chemistry or physics! LOL.)
You are going to be a shitty stratigrapher if you are not looking at borehole, well, and log data numerically.
How are you going to recognize subsurface faults without quantifying vertical shortening and repeat sections?
Unless you are just drawing cartoons, how are you going to quantify net sand, net pay, isopachs from the stratigraphy?
How are you going to ensure the log data is acceptable, without quality control on the well deviation, datum, borehole depth, annular conditions?
How are you going to use resistivity, electrical, and nuclear logs by ignoring numerical values?
