Title: Method of wellbore operations
Inventor: PETER JOHN WATSON
IPC: E21B47/11
Filed: 2020-09-02
Abstract: A method of estimating a real time production flowrate from a well by estimating a real time flowrate of a marker fluid in the well and comparing the estimated flowrate with a baseline marker fluid flowrate. The baseline marker fluid flowrate correlates to baseline production fluid flowrate obtained by introducing an amount of a marker fluid in the well, monitoring the time over which the marker fluid travels a set distance, and estimating a flowrate of the marker fluid based on the monitored time and amount of marker fluid. The real time production flowrate is obtained by extrapolating the baseline production fluid flowrate by an amount derived from a comparison of the baseline and real time marker fluid flow rates. In a gas lift assisted well, the marker may be a slug of higher density production fluid 52 formed by interrupting the gas lift and its effect on pressure is measured between sensors 54, 58 at spaced taps 56, 60. The slug velocity may be modified by a slip coefficient.
