Abstract
A method of digitizing a well log includes identifying automatically with a computational circuitry a legend and at least one graph of the well log; determining based on a machine learning a parameter of the at least one graph indicated in the legend; and digitizing the at least one graph based on the parameter.
Claims20
A method of digitizing a well log, the method comprising:
- identifying automatically with a neural network a legend and at least one well trace graph of a well log image associated with the well log, the well trace graph associated with measurements from a log of a well;
- applying optical character recognition and an identification engine to the legend to determine from the legend parameters associated with the at least one well trace graph, the parameters including a starting depth of a domain of the at least one well trace graph, a range of values represented by the at least one well trace graph, one or more cell dimensions of a grid shown in the at least one well trace graph, and a testing technique represented in the at least one well trace graph;
- and
- determining a set of paired measurements from the at least one well trace graph using the parameters to measure a domain value, a range value, and a unit of measurement for a paired measurement of the set of paired measurements.
