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. The methods further include correlating the plunger speed and the discharge duration to a discharge volume of liquid discharged from the hydrocarbon well.

Abstract: A hood that envelopes a hardhat and an air conduit assembly. The hood has a viewing window and defines a breathable air zone for a user. An aperture in the back of the hood allows a coupling port, which is part of the air conduit assembly, to extend out of the hood and couple to a source of filtered supplied air.

Abstract: A hardhat having a brim of variable elongation circumscribing its base is oriented such that the most elongate brim portion is associated with the back of a user's head. A source of supplied air is brought into an area proximate the back area, and an air conduit directs the air toward an area or areas of the hardhat having a less elongate brim.

Abstract: A hardhat having an outer major surface, and an air conduit coupled to the outer major surface. The air conduit has a geometric shape that generally follows the exterior of the hardhat, to deliver supplied air from the back of the hardhat to the front of the hardhat and closer to a breathable air zone of a user.

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 facilitating human interpretation of a plurality of time-series datasets generated from operation of hydrocarbon wells. The methods include obtaining the plurality of time-series datasets and displaying a vector map. The plurality of time-series datasets is generated from an operation of the hydrocarbon well and includes a first time-series dataset and a second time-series dataset, and optionally may include a third time-series dataset.

The memory stores instructions executable by the processor to, upon determining that a first fluid level in a vehicle container is below a threshold based on fluid level sensor data, determine a second fluid level based on a fluid consumption signal and the fluid level sensor, and to navigate the vehicle based on the determined second fluid level.

Abstract: A method and controller system are described for automatically tuning a controller of a drilling rig. The controller system includes a controller that determines a moving average of measured values, determines a moving standard deviation of the measured values, defines an outer zone of measured values with the determined moving average and the determined moving standard deviation, defines an inner zone of measured values with the determined moving average and the determined moving standard deviation, monitors the measured values for the occurrence of statistical events with respect to the outer zone and inner zone. Based on the detected statistical event, the controller adjusts the gain of the controller the based on the statistical event being associated with the outer zone or inner zone.
