ABSTRACT:
A method for providing improved measurement of oil, water, and gas flow rates in producing wells using thru-tubing wireline inflatable and retrievable packers or plugs to systematically isolate producing zones within a wellbore. Surface flow rates are measured before and after zonal isolation, with the zonal production rate determined by the measured difference in flow rate before and after isolation. Surface measurement of individual production zones allows greater accuracy in measuring multiphase flows, while at the same time allowing evaluation of reservoir properties of the lower, isolated zones.
