Methods and systems for enhancing well flow rate signal

A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:

• receiving flow rate data comprising a plurality of data values from a device measuring a flow rate of a fluid in a pipeline;
• receiving process variable data;
• determining a plurality of delta values by taking the difference of temporally adjacent data values;
• detecting discontinuities in the flow rate data by comparing the plurality of delta values to a continuity threshold;
• correcting data values associated with detected discontinuities with an interpolation method;
• identifying erroneous data values;
• determining a condition of the pipeline associated with each identified erroneous data value by evaluating the process variable data;
• correcting erroneous data values based on the condition of the pipeline;
• compiling unaltered data values and corrected data values into enhanced data flow rate data;
• and
• determining a daily production of hydrocarbons in the pipeline based on the enhanced data flow rate data.

A system, comprising:

• an oil and gas field;
• a flow metering device coupled, physically or virtually, to a pipeline in the oil and gas field, wherein the flow metering device measures a flow rate of a fluid in the pipeline and outputs the measured flow rate as flow rate data;
• a computer communicably connected to the flow metering device and comprises:
• one or more computer processors, and
• a non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:
• receiving the flow rate data comprising a plurality of data values;
• receiving process variable data;
• determining a plurality of delta values by taking the difference of temporally adjacent data values;
