Abstract

In the present study a numerical model, representative of a real gas-lifted oil well, is used to perform flow simulations under different states of the oil reservoir. The simulations results helped to establish correlations between the well state and the measurable parameters at the well head. The uniqueness of these correlations, allows the reliable diagnosis of the state of the well by inferring the anomalies affecting it based on easily measureable parameters with no need to stop the oil production.
