Abstract

This article includes an issue of applying a reservoir proxy model as a component part for geo-technological model of gas fields and underground gas storages. Authors have proposed an algorithm of applying the created proxy model into intelligent management system for gas fields and UGS. The task of proxy model creating is considered by the example of an underground gas storage “X” (the name of the object is encrypted commercial confidentiality reasons). All characteristics of the object “X” and the data on its actual operation mode, whereon model adaptation was performed, are given in the article. Authors have presented a detailed mathematical description of reservoir proxy model and considered the process of its creation, adaptation and integration into a geo-technological model complex of an object. Also, the limits of applicability of this method was determined. A Fully Functional Hydrodynamic (FFH) model of the “X” object was created in the commercial simulator «Schlumberger Eclipse» in order to assess the correctness of the reservoir proxy model, and a detailed comparison of the actual data and model calculations was conducted. In addition, the issue of using hydrodynamic models as a core of intelligent management system for reservoir development was considered in detail. The conclusions made by authors tell about the necessary of computing capacities, both for operation of the proxy model and the FFH model based on the commercial simulator. As a result of the research, conclusions about the applicability of the reservoir proxy model as an integral part of geo-technological model of gas fields and UGS were made.
