The article deals with the approach to gas pricing analysis based on the use of optimization models of gas supply systems. The object of the study is the Northeast Asian gas market. The model of the excessive gas supply system in Northeast Asia is described. The primal problem of the model is to minimize the sum of gas production and transportation costs under the infrastructure constraints. The solutions to the primal problem are the volumes of gas produced in each production point and transported via each route. The solutions to the dual problem (dual variables or shadow prices) are node prices in the points of gas supply system, the producers’ rent and the transporters’ rent. It is highlighted that the dual analysis plays an important role. It allows evaluating price relations between the points of gas supply system, identifying export routs characterized by the highest rent, evaluating the competitiveness of suppliers in the different scenarios of technological development, energy policy and market environment. The analytical capacities of the dual analysis are illustrated by the study of the impact of “unconventional” gas development in the importing countries on the Northeast Asian gas market environment. When the costs of unconventional gas production rise, gas trade patterns change, more competitive players enter the market, and gas prices in all consumption points as well as producers’ rents increase. It is concluded that if importers seek to lower import dependency while keeping the same price level, they have to lower the costs of unconventional gas production by technological development and/or to subsidize the industry to make it more competitive.

The paper presents a tool to optimize gas infrastructure systems and analyses some aspects of modelling related to autonomous gas consumers. A model of national gas infrastructure creation in Mongolia is proposed. The model is linked with the model of the regional Northeast Asian gas market and the financial models of gas infrastructure facilities. The model determines the optimal design of the national gas infrastructure system, i.e. the number of the facilities, their capacities, locations and the transport modes for connecting the consumption centres. The role of autonomous consumers is considered by introducing the demand for liquefied natural gas separately from the demand for pipeline gas. The scope of the model application is demonstrated by an illustrative example. The results show the rational natural gas import and distribution patterns. The need for expanding the energy cooperation between Mongolia and the other Northeast Asian countries to create gas industry in Mongolia is highlighted.

This paper proposes taking into account new properties of gas supply systems in a mathematical model of flow distribution in comparison with the traditional formulation. The approach suggests introducing an arc coefficient, which allows for changes in the magnitude of gas flow passing along the arc, a vector of an increase in the arc throughput, and lower constraints on the gas flow along the arc. We also propose considering a new economic environment, namely, new criteria for optimizing the flow distribution and setting fictitious gas prices for consumers. These criteria enable us to take account of the priority gas supply to a definite group of consumers. As an example, the calculation of gas flows for the aggregated Unified Gas Supply System (UGSS) for 2030 is considered. This calculation takes into account the arc coefficients and the increase in the throughput of arcs.

The sharp growth in unconventional gas production in North America has turned the gas market on its head. Unconventional gas (coal bed methane, tight gas and shale gas) is present in large volumes throughout the world—it offers the potential to continue to reshape global gas dynamics. Many expect the North America experience of sharp unconventional gas growth to be repeated elsewhere and are forecasting the perpetuation of a global gas surplus. Is this likely? We consider the impact of its development, identify some of the issues that will constrain its growth and address some of the implications for upstream suppliers, resource holders, buyers and policy makers. No post-Conference paper or slides are available for this presentation.

Introduction. A promising direction in the development of gas supply systems, which is widely used in the developed countries of the world, is the use of an alternative energy source — biomethane. The effective use of biomethane requires the development of scientific provisions and recommendations for the use of biomethane gas supply systems, taking into account technical and economic factors. Therefore, it is urgent to develop an economic and mathematical model for choosing a gasification method and determining the area of rational use of gas supply systems with biomethane. Materials and methods. To develop an economic and mathematical model for choosing a method for gasification of settlements, methods of mathematical modeling and parametric optimization were used. The implementation of the economic and mathematical model was carried out in the Mathcad software package. Mathematical and graphic processing of the results obtained was carried out. Results. An economic and mathematical model was developed for determining the rational area of application of biome­thane for gas supply to settlements. The model is based on the technical and economic calculation of the reduced costs for gas supply systems with network natural gas and biomethane. Using the developed model, the technical parameters of the biomethane gas supply system were determined: the critical length of the gas pipeline branch, the radius of the biomethane plant, the biomethane consumption, the length of the gas pipeline for the biomethane supply, and the reduced costs to the gas supply system. A graph of the dependence of the critical length of the gas pipeline branch on the population size has been obtained, which makes it possible to determine the area of rational use of biomethane for gas supply to settlements. It was found that for a rural settlement with a population of 5,000 people, the critical length of the gas pipeline branch is 24.820–28.044 km, for an urban-type settlement with a population of 15,000 people, the length of the gas pipeline branch is 50.923–64.677 km, and for a city with a population of 30,000 people — 89.617–127.279 km. Conclusions. The results obtained can be used for the development and design of gas supply systems based on biomethane for the gasification of settlements remote from the main gas pipelines. The use of biomethane makes it possible to gasify settlements in developed agricultural regions and to increase the efficiency of the gas transportation system of the Russian Federation.

The work is devoted to the urgent problem of using an alternative energy source of biomethane for gas supply to settlements. The effective use of biomethane in gas supply systems requires scientific substantiation, considering the entire range of technological parameters and operating conditions. The methods of graphs and parametric optimization are used to minimize the total reduced costs to the gas supply system to carry out the research. Based on the analysis of gas consumption by the municipal districts of the Belgorod region, a graphical dependence is built and an expression is obtained to determine the annual gas consumption by the population on the population size. The calculation of the mass of organic waste and the density of substrate formation is made, on the basis of which the potential for biomethane production in the municipal districts of the Belgorod region is determined. It has been established that the potential volume of biomethane in the Belgorod region is 633194 thousand m3 / year, or 11% of the total gas consumption. A diagram of the location of biomethane plants and gas pipelines for supplying biomethane to gas networks has been built. The optimal values of the technological parameters of the biomethane gas supply system have been established: the operating range of the biomethane plant depending on the substrate formation density, the length of the gas network for biomethane supply, depending on the gas consumption density.

The topical issues of development of automated control systems of gas control stations (GCS) and ways of reliable and economical functioning of the gas supply system in modern conditions have been considered in the article. The implementation of European innovative technologies, which are associated with using the modern equipment, telemetry tools to transmit the equipment operation parameters to the dispatcher control panel are the one of the ways to increase the safety and efficiency of GCS performance. The characteristic of the modern complex of telemetry, the raising of efficiency, reliability and safe operation of the gas supply systems due to the possibility of monitoring, technological control and management from the central dispatcher control room are given. The complex of telemetry helps to prevent emergency situations at facilities and to ensure control over unauthorized entry into the GCS premises by unauthorized persons. The article discusses the use of the automated system of operative-dispatching management (ASODM). It is a multi-level automated system that ensures the reliable functioning of the gas supply system at all levels of the hierarchy. It has been shown that the result of the creation of the ASODM are equipping of the control object with microprocessor control and management devices, the integration of various automation tools into a single information management system. It has been proven that the development of ASODM of GCS on the basis of local control and management modules using traditional approaches to creation of automation systems and using the cellular telephone communication as data transmission channels based on GSM-technologies are most rational. The digital control device, which is made on the technological platform of the programmable logic integrated circuit (PLIC), is the main element of the local control and management module. Digital control device (PLIC controller) is a relatively inexpensive and reliable equipment in an automated local GCS control system. The method of data transmission via GSM / GPRS wireless communication channel is considered. The use of GSM-modems and GPRS technology allows to remove restrictions on the distance of data transmission, as well as allows to fully automate the process of transmission and processing of information. The use of GSM / GPRS-technologies in the vehicles of the emergency dispatch service is also shown. The dispatcher can fully monitor the movement of the car with registration on the map of the city where the car is located.

Eastern Australia is now reliant on coal-seam gas (CSG) for its domestic gas supply; in 2018, it accounted for two-thirds of total eastern coast gas production. Australia has seen a rapid transition from relying on ‘conventional’ resources to relying on ‘unconventional’ gas supply. As legacy conventional supply sources mature and decline, exploration has been insufficient to keep up with market demand. This has created the opportunity for Australia’s vast CSG resources to fill the gap. But the development of CSG has been neither easy nor straightforward. And the costly requirement to drill hundreds, if not thousands, of wells in every single development has driven up the cost of supply. Most CSG reserves will be produced for the Pacific Basin LNG market via the three LNG projects on the east coast of Queensland. However, it is the resources beyond these LNG projects that will need to be developed, so as to ensure future supply to the east coast gas market. It is these other resources, both CSG and shale, that we evaluated to gain a picture of future gas supplies and costs. Our indicative economics showed that alternative CSG resources and Beetaloo shale both have high well-head break-even costs. In addition, the infrastructure required to get them to market will be expensive. The high costs, coupled with the demand from the LNG plants of Gladstone leads us to conclude that eastern-coast gas prices are likely to remain closely linked to global LNG prices for the foreseeable future.

This paper addresses opportunities for producers in the Victorian gas market arising from the ongoing reform of the Australian gas industry. Much of the impetus of the change has occurred in Victoria but to date there has been little evidence of the benefit of market reform to producers. This is expected to change.Until recently, Esso/BHPP had a secure hold on gas production into the Victorian market. The renegotiation of their gas supply agreement with Gas and Fuel has created opportunities for limited production from new producers in the short term and significant market options in the long term.Gas marketing companies are preparing to change the way they do business. Rigid long-term gas supply contracts will be balanced with alternative arrangements with producers such as financing of field development, equity investment in projects, alliances, commodity exchanges and the use of underground gas storage and LNG.The formation of a spot market for gas will allow a transparent market place to evolve where forward physical and paper transactions can take place. Trading of gas futures and options will provide a mechanism for producers to take up any risk position that meets their corporate strategy.In the light of market growth forecasts, flexible supply arrangements and market restructure, the potential for supply of natural gas by producers into the Victorian market is considerable.
