The Entropy Analysis of Changes in the Distribution of the Formation Fluid Filtration Characteristics for Oilfield Development Management

Abstract

Nowadays it is difficult to imagine control over the development of oilfields and increase of reservoir stimulation measures efficiency without the use of digital technologies. Availability of regularly updated database, digitalization of oil production facilities localization, developed data processing information technologies make it possible to create an online monitoring system under consideration objects work. Using digital algorithms makes it possible to monitor in real time all the information about the research object and the activities carried out current state, to assess their effectiveness, timeliness and compliance with standards, and to find reserves for improvement. Timely information about the need to carry out some actions is one of the most important elements of such a system, because it allows to carry out the process of oil production regulation in accordance with the set goals. The approach proposed in this article allows to promptly assess, using standard measured current well productivity data, the current distribution of hydrodynamic indicators along the strike in the pilot zone at any time. Comparative analysis of the distribution of indicators before and after the impact on the reservoir using the proposed method allows to increase the reliability of information about the current state of the reservoir system in the interwell space and to assess the effectiveness of the measures taken.
