WELL TESTING AND MONITORING

摘要

A technique facilitates testing and monitoring of a well. An artificial lift system is operated to produce a well fluid, and data is collected as the artificial lift system is operated at different flow rates. The data collected at the different, e.g. varying, flow rates is used in estimating flow performance and to enable continued monitoring of the well. In some applications, the data may be obtained by utilizing a virtual flow metering technique.

主权项

1. A method for monitoring a petroleum well, comprising:
operating an electric submersible pumping system in a wellbore to produce a fluid at a well flow rate; varying the well flow rate; calculating a flow rate of the electric submersible pumping system using a virtual flow metering technique; analyzing the calculated flow rate at different well flow rates to establish a differential in the calculated flow rates; and using the differential in the calculated flow rates to determine a performance parameter of the petroleum well.
