1. (WO2018132037) A METHOD FOR THE HYDRODYNAMIC CHARACTERISATION OF MULTI-RESERVOIR WELLS
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS

1 . A method for the determination of hydrodynamic parameters for each flowing reservoir, including:

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 and recording acoustic noise generated by reservoir fluid flow;

noise power calculation using reservoir fluid-flow noise logging data and subsequent multi-phase hydrodynamic modelling to determine hydrodynamic parameters for each identified reservoir.

2. A method according to Claim 1 in which fluid flow is characterised by measuring at least wellbore pressure.
