1. A method of digitizing a well log, the method comprising: determining a set of possible connections between a cluster and two or more adjacent clusters in a well log image modified to remove grid lines, each connection of the set of possible connections connecting the cluster to one adjacent cluster of the two or more adjacent clusters; providing the set of possible connections to a trained trace analysis engine, for each connection of the set of possible connections, the trained trace analysis engine determining a probability that a select connection of the set of possible connections is associated with a select well trace of a set of well traces; allocating the select connection to the select well trace when the probability that the select connection is associated with the select well trace is greater than a probability that the select connection is associated with other well traces of the set of well traces, the select connection defining a portion of the select well trace to include the cluster and an adjacent cluster to which the cluster is connected by the select connection; and determining a digital paired value including a range value and a domain value of the cluster according to a position of the cluster within the well log image and allocating the digital paired value to the select well trace.
