This paper replicates the analysis in the paper 'What Drives Natural Gas Prices?" by Stephen P.A. Brown and Mine K. Yücel. The replication confirms the results of that analysis: a long-run relationship existed between natural-gas prices and crude-oil prices during the period from June 1997 to...

Over the years Bulgaria has remained strongly dependent on its import of oil products mainly due to the lack of oil resources on its territory. This import dependence poses a significant risk for the country’s energy security. In this research we analyse Bulgaria’s energy security in terms...

This paper examines how oil and gas companies' reserves growth affects their share price returns. In particular we examine three issues affecting the relation between reserves changes and oil and gas firm returns. First, we examine if investors value reserves replacement as a result of...

Underground gas storage (henceforth; UGS) is considered as a common method which resolves the seasonality problem of transportation and distribution of gas phase in the oil and gas industries. The main objective of this study is to simulate one of Iranian's depleted gas condensate reservoir and...

The ubiquitous consumption of hydrocarbon fuels in a vast majority of industrial purposes has been dramatically increased in the coming decades. Therefore, the reason why numerous studies experimental investigations are being done is to enhance the oil recovery factor. Low salinity water...

This research quantifies the impact that regular road traffic congestion has on the CO2 emissions of a real-world distribution network, and it studies the consequences when the number of distribution centers changes. For this purpose, this study makes use of a network model allowing for a...

Purpose: This work presents a general model in mixed integer programming that integrates the design of the territory and distribution route planning, seeking to minimize the total distance covered by the vehicle in each territory. Design/methodology/approach: In this work, a mathematical...

The main aim of following research paper is the definition of logistics coordination in the distribution network. Research paper also is aimed on distinguishing the further research steps. Research methodology focuses on the problematic of literature review in the conditions of coordination,...

A novel single-ended travelling wave fault location method applicable to the distribution network with multi-branches is presented in this paper. The method only depends on the arrival times of the initial aerial-mode and zero-mode travelling wave, and it can solve the truncation error problem...
