Pick Confidence is a subjective value assigned to each Strat Pick record to indicate of the “believability” of a particular Strat Pick. The Pick Confidence is assigned by the geologist at the time a new Strat Pick is entered. The purpose of Pick Confidence is to run queries of the Strat Picks that exclude values below a certain confidence level.
Caution. Values have not been systematically assigned to wells before 2001:
The values assigned to Pick Confidence are listed in the Pick Confidence Values Table.
