Flow rate optimizer

A processing system for hydrocarbon monitoring, the processing system being configured to:

• receive downhole measurements of a flowing fluid from a flowmeter;
• determine a standard phase fraction and a speed of sound (SoS) of a first phase of the flowing fluid based on the downhole measurements from the flowmeter;
• receive surface measurements of the flowing fluid;
• determine a surface phase fraction of the flowing fluid based on the surface measurements;
• compare the standard phase fraction to the surface phase fraction to generate a comparison;
• adjust, based on the comparison being greater than a predetermined threshold and using the surface measurements as a reference, the SoS of the first phase until a target value is achieved, to generate an adjusted SoS of the first phase;
• and
• receive additional downhole measurements of the flowing fluid from the flowmeter, the flowmeter being configured to operate using the adjusted SoS of the first phase for the additional downhole measurements.

A non-transitory computer-readable medium comprising instructions executable by a processing system to perform operations for hydrocarbon monitoring, the operations comprising:

• receiving downhole measurements of a flowing fluid from a flowmeter;
• determining a standard phase fraction and a speed of sound (SoS) of a phase of the flowing fluid based on the downhole measurements from the flowmeter;
• receiving surface measurements of the flowing fluid;
• determining a surface phase fraction of the flowing fluid based on the surface measurements;
• comparing the standard phase fraction to the surface phase fraction to generate a comparison;
• adjusting, based on the comparison being greater than a predetermined threshold and using the surface measurements as a reference, the SoS of the phase until a target value is achieved, to generate an adjusted SoS of the phase;
• and
• receiving additional downhole measurements of the flowing fluid from the flowmeter, wherein the flowmeter is operating using the adjusted SoS of the phase for the additional downhole measurements.
