<p>In accordance with an illustrative embodiment of the present invention, a method is disclosed for processing production logging data in order to determine, in a two-phase, water-oil, flow, the flowrate of one of the phases at different depths of a production well. At each depth, data representative of the total flowrate and of the proportion of total cross section of pipe occupied by one of the phases, designated "hold up," is generated. For each depth, the slippage velocity between the two phases is computed from the data representative of hold up and of a parameter which is a function of the difference in density between the two phases. The flowrate of each phase is then computed from the previously computed values of slippage velocity and from the data representative of total flowrate and hold-up. This method gives precise quantitative data making it possible to determine the operations required to improve the production of the well.</p> |
