Title: A METHOD FOR THE HYDRODYNAMIC CHARACTERISATION OF MULTI-RESERVOIR WELLS
Abstract:
This invention relates to the oil-producing industry and can be used in operating multi- reservoir wells. A method for the determination of hydrodynamic parameters for each flowing reservoir that includes reaching at least one well operating mode with fluid flow through both the wellbore and one or more reservoirs, measuring at least one parameter that characterises fluid flow, recording its acoustic noise logging data, calculating noise power using reservoir fluid flow noise logging data, and subsequent multi-phase hydrodynamic modelling to determine hydrodynamic parameters for each identified reservoir. One independent claim, one dependent claim, six figures.
