Well testing apparatus and methods for measuring the properties and performance of oil and gas wells

摘要

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.
