Effective approaches to improve the deliverability of production wells have been scientifically substantiated and implemented, which makes it possible to increase the potential daily deliverability of UGS facilities in order to ensure the control over various fluctuations in gas consumption within the UGSS;

technologies for the mechanical removal of bridging agent by milling the production casing and further enlarging the well bore (for wells with perforated casing completion) or by enlarging the cavity diameter (for wells with extended-reach bottom-hole zones) have been adopted at seven UGSs;

a method for the diagnostics of a bottom-hole zone has been improved on the basis of gas dynamic-research data;

five technical devices and a method for extended-reach open-hole well completion ensuring the survival of artificial bottom-hole structure and preventing sand production have been developed and patented.

The implementation of the developed technology has significantly increased well productivity, while simultaneously reducing draw-down pressure (for instance, the well productivity rate at the Kaluzhskoye UGS has grown averagely 3.9 times, while draw-down pressure has decreased 2 times).

Creation of an automated document management system for Gazprom on the basis of a specialized hardware and software package

An automated document management system (hereinafter – ADMS) has been designed, developed and implemented at Gazprom on the basis of a specialized hardware and software package.

In the course of their work, the authors have accomplished the following tasks:

• unification and automation of document processing at all Gazprom's units;
• processing of incoming, internal, outgoing and administrative documents, as well as draft contracts, including documents with restricted access, completely in electronic format;
• the use of a mechanism for signing documents with electronic signature (e-signature) for internal documents and letters of instruction, as well as for approving draft documents using e-signature for internal, outgoing, administrative documents and draft contracts;
• automated registration and mailing of documents and letters of instruction, once they have been signed;
• increasing the processing speed of incoming, administrative and outgoing documents by applying batch scanning with the use of bar-coding technology;
• simplification of document search by using full-text recognition of documents and appendices;
• development and implementation of formal rules for the differentiation of managerial decision-making rights, such as signing, approving and giving assignments, depending on the level of document management;
• automation and formalization of the procedure for supervising the execution of documents and assignments;
• enhancing the efficiency of preparing analytical statements regarding the progress in the execution of documents and assignments as a result of the automatic generation of various reports.

Leading-edge solutions for the control of managerial information handling processes have been provided as part of the ADMS implementation.

The developed solution has proven its efficiency in terms of enhancing the quality and promptness of managerial decision-making, as well as reducing costs, including time expenditures, for the document management process at Gazprom as a benefit of transitioning to a paperless office. A similar positive effect can be achieved at the corporate level as a result of organizing electronic document exchange among the Gazprom Group companies with the use of the implemented ADMS.

Single economic and mathematical model for estimating the balances and flows of gas via the UGSS of Russia with splitting the general gas flow into supply lines and for calculating Gazprom’s economic indicators

A mathematical model that uses the algorithm for splitting the volumes of gas flows and estimating the amount of works for product transmission splitted by supply lines has been developed.

The model has been implemented as a large-scale optimization task (about 40,000 variables) with the use of graph theory methods and makes it possible to perform calculations with regard to various system tasks related to gas transmission via Gazprom's gas trunkline system. The Gas transmission plan for a medium-term planning period based on economic criterion is generated using the model.

A software application has been created on the basis of the model with the use of state-of-the-art software development tools. The software application has been fully implemented by Russian developers; the copyright for all source codes and software modules belongs to Gazprom; a number of software applications have been officially registered.

The use of the model is regulated by the directive document entitled “Guidelines for splitting the general volume of gas flow into supply lines” approved by Gazprom's order.

Upgrade of the GTK-25IR gas turbine unit in terms of power supply and environmental aspects using cutting-edge domestic solutions

The works on the upgrade of the GTK-25I(R) gas turbine unit in terms of power supply and environmental aspects have been performed with the use of cutting-edge domestic solutions.

A new regulation algorithm that makes it possible to maintain a constant specific rotation frequency of a turbo-compressor shaft and maximum temperature of combustion products has been developed and integrated into the automatic control and regulation system of gas compressor unit (GCU), which helps make the best use of the fuel economy potential available in the gas turbine unit configuration.

A special device that provides a stable output voltage in the whole range of generator operating modes has been applied in order to maintain the GCU's independence from power supply variations.

A low-emission premixed combustion chamber has been developed and integrated into the structure of the GTK-25IR gas turbine unit, which provides the required conditions for the automatic maintenance of optimal mixture composition in the local part of combustion area.

The implementation of the optimal regulation algorithm in the GTK-25IR gas turbine units operated by Gazprom Transgaz Yugorsk makes it possible to save the amount of fuel gas equal to 126 million Nm3 per year.

The integration of premixed combustion chambers into gas turbine units of the GTK-25IR series helps reduce the gross emissions of nitrogen oxides by more than 10,000 tons per year.

The developed solutions are patented.

Development and launching the production of domestic plasma technologies and equipment for metal cutting & gouging and insulation stripping for the use during repair operations at gas trunklines

Air-plasma machines for cutting & gouging of pipe metal and plasma stripping of insulation coatings, which are classified as equipment for on-site (field) repairs of trunklines, have been developed and put into production.

The use of plasma technologies for metal processing in field conditions makes it possible to significantly increase the pace of such production processes as cutting and removing defective metal during repair operations at welds, as well as when repairing corrosion and stress corrosion defects, and to reduce the labor intensity during the installation and start-up of the technological equipment.

The use of the created technologies and equipment is stipulated by the regulatory documents (standards, guidelines, instructions, etc.) developed by the authors of the research work.

Development and implementation of the methodology for increasing gas supplies to consumers via gas distribution stations in excess of their design capacity without investment in reconstruction

Approaches to re-estimating the technological capabilities of existing gas distribution stations (GDSs) as regards the increase of their throughput capacity above the designed level so as to reach the best technically possible value have been scientifically substantiated and implemented at Gazprom.

A set of measures has been developed to formally transfer GDSs to the increased throughput capacity that exceeds their design capacity in accordance with the legislation of the Russian Federation.

In the course of the research work, a comprehensive analysis of the technical characteristics of GDS equipment has been performed using multivariate thermal and hydraulic calculations in accordance with the specially designed mathematical model.

The developed methodological approaches are regulated by the standard of Gazprom Transgaz Moscow entitled “Guidelines for estimating the technically possible throughput capacity of GDSs.”

The extension of said development throughout Gazprom will make it possible to eliminate the costs for the reconstruction of GDSs that is planned in the near future in order to enhance the throughput capacity of GDSs in excess of their design value and to increase Gazprom's profit thanks to additional gas supplies via the existing GDSs.
