Abstract

See full text

A method is provided for determining the frequency of a multi-rate well testing operation in a gas-lifted hydrocarbon well. A well performance characteristic of the well is monitored using single-rate well tests. The monitored well performance characteristic is compared to a current well model performance characteristic. If the monitored well performance characteristic differs from the current well model performance characteristic by less than a predetermined amount, an amount of gas is injected into the well based on the current well model performance characteristic. If the monitored well performance characteristic differs from the current well model performance characteristic by more than a predetermined amount, a multi-rate well test is initiated the results of the multi-rate well test are fitted to a revised well model performance characteristic, and an amount of gas is injected into the well based on the revised well model performance characteristic.
