With a history of less than two decades, the Portuguese natural gas sector is still growing. Consequently, the impact of regulatory reform is evidently recent. The aim of this paper is to assess the performance of the Portuguese gas distributors in order to define the efficiency targets for the regulatory period, 2010–2013. It also conducted further analysis in order to determine the best level of...
The Dutch gas distribution grid faces several changes in the near future. Among others, the share of green gas will grow, the interaction with the electricity distribution grid and local heat grids will increase, and the grid will transform from a mono-gas system to a multi-gas system. The gas distribution grid is likely to be expanded with novel components, e.g. blending stations, gas storage sites,...
TOU price is an effective measure to achieve short-term balance of natural gas market, and a reasonable adjustment of natural gas price is the key to the implementation. Based on related research, some parameters are described through probability distribution, and use the price elasticity to reflect the customers' response to TOU prices, then consider the uniformity of gas using, take Monte-Carlo...
At present, there has a problem that the gas source in Vehicle CNG stations(VCS) supplied in short in the domestic vehicle market which has huge potential. This paper suggests Gas company proposed the organization, environment-friendly energy fund(EEF), that corporate money market funds to gather plenty of private capital to make or pay the smooth implementation of this economic strategy, thus ensuring...
Gas transmission and distribution system, the gas load is the main parameter to impact the project planning, which determines the capacity of equipments and operation program. Therefore, accurate prediction of gas load is of extremely important significance for gas companies to improve safety and reliability of gas supply. The forecasting method of tradition gas load would not meet the requirement...
This study continues the issue of Russian economic reform in the study by Quast and Locatelli (1997) and extends the same reform in many aspects. In this article, in-depth study is also made in the reform strategies (vertical and horizontal integration and diversity) and the business performance of Gazprom, Russia's natural gas company, as Russian had tried to save its domestic political and economic...
The comprehensive numerical simulation and analysis of flow field in the three-dimensional model of cyclone in three-phase test separation were performed by Fluent. Using RSM, the turbulence numerical simulation method, the relationship was researched between each parameter and the separation efficiency of cyclone, such as pressure, coning, overflow pipe diameter, then select the appropriate parameter...
Proven natural gas reserves are identified through continuous development of knowledge of geological models. The geological setting is the basis of reserves, and knowledge of geological models is a determining factor. The improvement of exploration techniques is a controlling factor, and the market demand is a stimulus. Exploration work required for discovery is a necessary factor, and Government...
Increased emphasis on national critical infrastructure protection has accelerated the need to respond to infrastructure assessment requests in a timely manner with reasonable certainty of system consequences following either natural or deliberate system disruptions. Natural gas supply, transmission, and distribution networks provide an important capability to dependent electric power, industrial,...
Since the pricing mechanism for natural gas prevailing in China being not conform to the development of natural gas market, a systematical analysis is employed in the study in term of the present situations and disadvantages on the market characteristics and the pricing mode. On the basis to the comparison with the rules of the pricing mechanism for natural gas in developed countries, a detail design...
Given the predicted global increase in energy demand, securing Europe's future energy needs will become of high geopolitical and strategic importance. Apart from the European strong dependence issue, another relevant issue involves the reliability of the infrastructures, as far as possible accidents and terrorist attacks are concerned. Indeed, vulnerability to oil and gas supply interruptions poses...
This paper proposes a mathematical model to manage natural gas supply and energy portfolio of a generation company. The model incorporates financial risks associated with the decision-making process of buying and selling both natural gas and electricity while keeping the interaction between the two markets. Using stochastic programming framework, the problem formulation considers uncertainties associated...
With the development of economy and the pressure of environment pollution, natural gas industry have been developing as fast as well in recent years in China. Because of the unbalance distribution of natural gas resources in China, transportation pipelines have been developing quickly. There is huge pressure energy stored in the pipeline networks. A gas-steam combined cycle recovering pressure energy...
In recent years, the world energy market has changed significantly. Especially, the demand of the oil has been increasing day by day. The natural gas was only the accessory of the crude since its discovery. Some expertise predicts that natural gas will be the first energy in the future. As one of the most potential future energy, natural gas will play an increasingly important role during the country's...
We examine the problem faced by owners of gas storage contracts of how to manage the injection/withdrawal schedule of natural gas, given historical price behavior and a predictive model of future prices. We describe a hybrid price prediction model that combines a support vector machine technique with a stochastic model for short and long-term gas prices, respectively. We present a theoretical result...
As the efficient clean natural resource, natural gas has become the world top choice of ameliorating environment and promoting sustainable development on economy. It is estimated by International Information Center of Natural Gas that in 2000 world primary consumption gross of natural gas is 2.5 tril cubes, which accounts for 22% of the total consumption of non-renewable resource. As a result of competitive...
In this article we expose the status and outlook of the market dynamics and its related infrastructure in the South East Europe (SEE). An important emphasis is given in the actual coalitions that will assist in the faster and more robust development of the gas sector in SEE, the existing infrastructure, the future projects that are under development on under study and the regulation that is needed...
In this paper, to set R&D priorities at sector level, a developed method is proposed which is combined of scenario planning and critical technologies method and then applied for prioritizing R&D issues of membrane technology in National Iranian Gas Company (NIGC). In the first phase (through 3 steps), scope of NIGC is mapped using national documents and viewpoints of experts and managers....
US and Canadian gas consumers are averse to long-term physical contracts - the traditional mechanism for securing LNG in the world market. While North America will become increasingly reliant on LNG, without committing to this form of natural gas supply, it may not be available if needed in the years ahead. We highlight the risk that in any given period, LNG flows could fall to low levels, even zero,...
There are currently a number of existing oil sand Mega-Projects as well as many other related projects planned and under construction in the Alberta oil sands region. There are many challenges facing the oil sands. The demanding climate conditions cost of extraction, environmental, energy constraints as well as the rising construction costs are examples. To develop this huge petroleum reserve, these...
