Abstract: A method of identifying hydrocarbon production information is disclosed. In in a first hydrocarbon management environment, a first audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprint is stored in a memory, along with identifying information associated with the first signal. A second audio signal is detected and a characteristic acoustic fingerprint is identified therefrom. The fingerprints are compared, and if the fingerprints match the identifying information of the first audio signal is assigned to the second audio signal. A notification regarding the matching of the characteristic acoustic fingerprints of the first and second audio signals is issued.

Abstract: Methods of increasing efficiency of plunger lift operations and hydrocarbon wells that perform the methods are disclosed herein. The methods include monitoring an acoustic output from the hydrocarbon well. The methods also include calculating a plunger speed of a plunger of the hydrocarbon well as the plunger travels toward a surface region and calculating a discharge duration of a liquid discharge time period during which liquid is discharged from the hydrocarbon well.
