Abstract
A method for optimizing the production of a petroleum well is provided. The petroleum well includes a borehole, a piping structure positioned within the borehole, and a tubing string positioned within the borehole for conveying a production fluid. Production of the well is optimized by determining a flow rate of the production fluid within the tubing string and determining a lift-gas injection rate for the gas being injected into the tubing string. The flow rate and injection rate data is communicated along the piping structure of the well to a selected location, where the data is collected and analyzed. After analysis of the data, an optimum operating point for the well can be determined.
