Abstract
A dynamic calibration system and method for measuring flow rates for individual petroleum wells in a well pad are provided. The dynamic calibration system and method include means for performing custom-calibration of said pressure sensor for each individual well to enhance the accuracy of the resulting flow rate measurements.
Claims17
A system for measuring flow rates for effluents of individual petroleum wells in a well pad, comprising:
- a multiphase flowmeter comprising a pressure sensor;
- a valve assembly connected between each of the individual petroleum wells and the multiphase flowmeter that connects and disconnects an effluent from a single selected individual well to the multiphase flowmeter;
- and
- means for performing custom-calibration of said pressure sensor for each individual well to enhance the accuracy of the resulting flow rate measurements.

A method for measuring flow rates for individual wells in a well pad by a single multiphase flowmeter, comprising:
- determining a pressure drop range for each of the wells in the well pad;
- selecting a first individual well for which a pressure drop range has been determined;
- calibrating a differential pressure sensor of said multiphase flowmeter with the pre-determined pressure drop range corresponding to the selected well, and
- measuring the flow rate of a fluid from the first selected well.
