Abstract: A method can include calibrating a model using pressure and flow rate data to generate a calibrated model; receiving an upstream pressure value and a downstream pressure value that define a pressure differential across a flow device; and computing a flow rate through the flow device using the upstream pressure value, the downstream pressure value and the calibrated model.

Abstract: A method can include receiving a number of samples of liquid production values and associated gas-lift injection rates for one of one or more wells; determining a prospective optimal gas-lift injection rate for the one of the one or more wells via a regression that fits the number of samples; responsive to the prospective optimal gas-lift injection rate satisfying one or more gas-lift injection rate criteria, issuing an instruction to implement the prospective optimal gas-lift injection rate for the one of the one or more wells; receiving a new sample as a measured liquid production value for the implemented prospective optimal gas-lift injection rate and responsive to satisfaction of one or more compliance criteria; and replacing one of the number of samples with the new sample.

Abstract: A device includes a memory configured to store first executable code and a processor coupled to the memory. The processor is configured to calculate performance indicators for a sucker rod pump (SRP) based on performance data of the SRP, determine an operational frequency corresponding to operation of the SRP based on one performance indicator selected from the performance indicators, and initiate transmission of a control signal corresponding to the operational frequency to alter operation of the SRP to correspond to the operational frequency.

Abstract: A method can include receiving data for a well; determining a gas flow rate and a liquid level for the well; determining an amount of chemical to inject into the well based on the gas flow rate and the liquid level; and issuing a signal to chemical injection equipment to inject the amount of chemical into the well.

Abstract: An automated system for managing gas in an annulus of a production well at a well site, the automated system including: an electrically-controlled valve fluidly coupled to the annulus of the production well, wherein the valve is located at or near the surface at the well site; at least one well sensor configured to measure operational characteristics of the production well at or near the surface; and a gateway device, located at the well site and operably coupled to the valve and the at least one well sensor, wherein the gateway device is configured to collect first sensor data communicated from the at least one well sensor, and process the first sensor data in autonomous control operations that automatically generate and issue commands that are communicated from the gateway device to the valve to regulate the outflow of accumulated gas from the annulus of the production well over time.
