Abstract

Many experts admit a big gap between reservoir simulation and daily management of oil and gas fields. Because only a limited number of specialists can use the results of modeling and models get out of date quickly. The necessity to reduce access and update time has driven to development of a Live Model concept. It will reduce the gap between modeling and practical oil and gas field management.

The targets of Live Model concept are:

  • use models as interactive means of teaching;

  • make models available to everyone, everywhere, anytime;

  • build updating and monitoring tools for models.

In accordance with Live Model concept we developed web-system which enables to perform model monitoring and analysis of reservoir simulation results. Using this tool any specialist by means of a web-browser can do the following:

  • make analysis of dynamics well data;

  • make maps, streamlines visualization;

  • estimate the quality of the models history matching;

  • create and calculate a simple model.

This web-system can act as an integral part of corporate information-engineering portal. Then we have opportunity to use dynamic production data, which is stored in corporate database, and automatically update Live Models. The interaction of web-system for models monitoring and analysis with the corporate database and models accessibility helps the oil and gas companies to use modeling results in the process of decision-making more efficiently. Another crucial factor is the opportunity to employ Live Models as training aids, which significantly reduces learning curve and increases the quality of training.

Introduction

Oil and gas field reservoir simulation plays a key role in:

  • the understanding of physical processes observed in the formation and in wells;

  • the working out of a strategy at initial stages of field development;

  • exercising control over the oil and gas fields at later stages of field development.

However in daily base fields performance monitoring and management we face with the several factors which prevent an efficient using of reservoir simulation. First of all, only a limited number of specialists can use the results of modeling and have an access to these models. In most cases only model creater has an access to models he created. So, reservoir engineer became a bottle-neck to the simulation results (see Fig. 1).
