Abstract
A method can include detecting instability of multiphase fluid flow in a multiphase fluid production system using sensor measurements from the multiphase fluid production system; and, responsive to the detection of instability, increasing gas injection into the multiphase fluid production system until a variation metric of the sensor measurements decreases to a level indicative of stable multiphase fluid flow in the multiphase fluid production system.
Claims20
A method comprising:
- detecting instability of multiphase fluid flow in a multiphase fluid production system using sensor measurements from the multiphase fluid production system;
- and
- responsive to the detection of instability, increasing gas injection into the multiphase fluid production system until a variation metric of the sensor measurements decreases to a level indicative of stable multiphase fluid flow in the multiphase fluid production system.
A system comprising:
- a processor;
- memory accessible by the processor;
- and
- processor-executable instructions stored in the memory wherein the instructions comprise instructions to instruct the system to:
- detect instability of multiphase fluid flow in a multiphase fluid production system using sensor measurements from the multiphase fluid production system;
- and
- responsive to the detection of instability, increase gas injection into the multiphase fluid production system until a variation metric of the sensor measurements decreases to a level indicative of stable multiphase fluid flow in the multiphase fluid production system.
One or more computer-readable storage media comprising computer-executable instructions executable by a computer, the instructions comprising instructions to:
- detect instability of multiphase fluid flow in a multiphase fluid production system using sensor measurements from the multiphase fluid production system;
- and
- responsive to the detection of instability, increase gas injection into the multiphase fluid production system until a variation metric of the sensor measurements decreases to a level indicative of stable multiphase fluid flow in the multiphase fluid production system.
