Abstract
A hydrocarbon mud log and a natural gamma-ray mud log are recorded for well drilling operations. A natural gamma-ray wireline log is run in the well following drilling operations. The natural gamma-ray mud log and natural gamma-ray wireline log are correlated to identify the correct depth interval of gas shows on the hydrocarbon mud log.
