Analyzing the State of Oil Field Development Based on the Fisher and Shannon Information Measures

Abstract

For the time series that describe the amounts of crude and load oil, the Fisher and Shannon entropies as well as other information measures are calculated. Their dynamics are used for performing an early diagnosis of the temporal limits of the oil field evolution, including its separate zones, and also for evaluating the state of oil production in response to planned bed stimulation. The suggested method is tested on the Forties Oil Field data. In accordance with the experimental results, oil field exploitation without considering the dynamics of these information measures reduces oil production, increasing the output of water-cut oil and causing an inefficient mode of bed stimulation.
