Abstract
To determine properties of multiple oil and gas wells, oscillations at different test frequencies are applied to the flow rate and/or pressure of multiple wells. Measurements of flow rate and/or pressure and temperature in flows downstream of a production header of the multiple wells are then obtained. Such measurements from the flows of the multiple wells are subjected to a frequency analysis of the pressure, flow rate and/or temperature measurements to determine pressure, flow rate and/or temperature variations induced by the applied oscillations. Properties of the different wells of the multiple wells based on the results of the frequency analysis are thus determined.
