Abstract
A method for determining flow information of a well producing fluid from a subsurface formation comprising. The method comprises obtaining at least one first production measurement from the well. The method comprises obtaining, with a sensor, a first measurement generated by the fluid flowing through a device. The method comprises inputting the first measurement and the at least one first production measurement into a virtual flow meter. The method comprises determining, via the virtual flow meter, a multi-phase flow rate of the fluid based on the first measurement and the at least one first production measurement.

A computer-implemented method for determining flow information of a well producing fluid from a subsurface formation comprising:
- obtaining at least one first production measurement from the well;
- obtaining, with a sensor, a first measurement of an acoustic signal generated by the fluid oscillating in an asymmetric acoustic device, wherein the asymmetric acoustic device is configured to cause the fluid to oscillate as the fluid flows through the asymmetric acoustic device;
- inputting the first measurement and the at least one first production measurement into a virtual flow meter;
- and
- determining, via the virtual flow meter, a multi-phase flow rate of the fluid based on the first measurement and the at least one first production measurement.
A non-transitory computer-readable medium including computer-executable instructions comprising:
- instructions to obtain at least one first production measurement from a well producing fluid from a subsurface formation;
- instructions to obtain, with a sensor, a first measurement of an acoustic signal generated by the fluid oscillating in an asymmetric acoustic device, wherein the asymmetric acoustic device is configured to cause the fluid to oscillate as the fluid flows through the asymmetric acoustic device;
- instructions to input the first measurement and the at least one first production measurement into a virtual flow meter;
- and
- instructions to determine, via the virtual flow meter, a multi-phase flow rate of the fluid based on the first measurement and the at least one first production measurement.
A system comprising:
- a sensor;
- an asymmetric acoustic device configured to cause a fluid to oscillate as the fluid flows through the asymmetric acoustic device;

- a computer-readable medium having instructions stored thereon that are executable by the processor, the instructions including
- instructions to obtain at least one first production measurement from a well producing the fluid from a subsurface formation;
- instructions to obtain, with the sensor, a first measurement of an acoustic signal generated by the fluid oscillating in the asymmetric acoustic device;
- instructions to input the first measurement and the at least one first production measurement into a virtual flow meter;
- and
- instructions to determine, via the virtual flow meter, a multi-phase flow rate of the fluid based on the first measurement and the at least one first production measurement.
