Abstract
A method for estimating the gas-oil ratio (GOR) of a flowing oil well in real-time includes installing a first pressure downhole monitoring system in a flowing oil well, and installing a second pressure downhole monitoring system in a flowing oil well such that a pressure gradient can be calculated between a pressure measured by the first pressure downhole monitoring system and a pressure measured by the second pressure downhole monitoring system. Then the pressure is measured at the well-head of the oil well, and previous production test results of the oil well are reviewed in order to collect a liquid flow rate from the measured well-head pressure. Finally, known correlations between liquid flow rates and pressure gradients at constant GOR values are used to determine the GOR of the well.
