CORIOLIS DIRECT WELLHEAD MEASUREMENT DEVICES AND METHODS

摘要

Coriolis direct wellhead measurement devices and methods are provided. The devices and methods allow for continuous monitoring, more frequent data, and greater accuracy in quantitative and qualitative measurements of well performance. In an embodiment: an entrained gas severity of a wellhead is determined based on a determined drive gain threshold, at least one variable is output based on the determined entrained gas severity, and a respective confidence indicator correlating to the at least one variable is output. One mode of operation includes continually averaging the at least one variable over a predetermined time interval and out-putting a respective single averaged data value. Another mode of operation includes outputting at least one instantaneous variable at predetermined and uniform time intervals. Diagnostic information and user alerts are also output to provide reliable decision making information to an operator.

主权项

1. A method for direct wellhead measurement of at least one well, the method comprising:
determining an entrained gas severity of the at least one well, where the entrained gas severity is based on the amount of entrained gas exceeding a determined drive gain threshold; and outputting at least one variable based on the determined entrained gas severity.
