A method is provided for evaluating the performance of a plurality of oil wells which were established to produce from a common reservoir beneath the earth's surface comprising inputting information about the reservoir into a computer and establishing a time interval and time steps within that time interval over which performance of the wells will be evaluated, determining the total oil which is accessible during each time step in each time interval, and then individual recovery factor for each time step is determined. A composite recovery factor is determined using the individual recovery factors. The composite recovery factors are preferably normalized to the best well in the field and used to determine if a well is under performing. |
