Abstract:Gas export is one of the considerable choices in gas consumption to obtain foreign ex-change direct income by the government. Gas can be transformed and exported by various forms such as LNG and GTL. All forms of gar transformation and its export row gas with a convertible coefficient. Therefore, gas export means the total gas export through pipelines, LNG on the other forms of g...

I use daily futures price data to examine the behavior of natural gas and crude oil price volatility in the U.S. since 1990. I test whether there has been a significant trend in volatility, whether there was a short-term increase in volatility during the time of the Enron collapse, and whether natural gas and crude oil price volatilities are interrelated. I also measure the persistence of shock...

Natural gas demand in the United States has been increasing for the last 15 years and is projected to grow substantially in the next 20 years. Meeting this growing demand will require an accompanying increase in supply, which is expected to come mostly from additional production in the United States. The prospect of increased U.S. production has led to ongoing efforts both to better assess our ...

Gas hydrates form when water and natural gas combine at low temperatures and high pressures — for example, in regions of permafrost and in marine subseafloor sediments. They exist in abundance worldwide and some estimates suggest that the total amount of natural gas bound in hydrate form may exceed all conventional gas resources, or even the amount of all hydrocarbon energy — coal, oil and natu...

Abundant availability and potential for lower CO2 emissions are drivers for increased utilization of natural gas in automotive engines for transportation applications. However scarce refueling resources for on-road vehicles impose an infrastructure limited barrier on natural gas use in transportation. A novel ‘bimodal’ engine which can operate in a compressor mode has been developed that allows...

Gas compressibility factor (z-factor) is an important parameter widely applied in petroleum and chemical engineering. Experimental measurements, equations of state (EOSs) and empirical correlations are the most common sources in z-factor calculations. However, these methods have serious limitations such as being time-consuming as well as those from a computational point of view, like instabilit...

in this paper, a model based on gmdh type neural network, is used to predict gas price in the spot market while using oil spot market price, gas spot market price, gas future market price, oil future market price and average temperature of the weather. the results suggest that gmdh neural network model, according to the root mean squared error (rmse) and direction statistics (dstat) statistics ...

This study examines the pre-announcement performance of Canadian takeover targets and measures the relation between performance and the turnover rate of target firm top managers (Chief Executive Officers or Presidents) following the announcements. We find negative correlation between pre-announcement performance and the turnover rate. We find that the pre-announcement performance of targets tha...
