Underground gas storage is the practical means of making available the increased supplies of natural gas that are needed in Indiana in winter periods of peak demand. To date, 21 gas storage projects providing an estimated storage capacity of 48 billion cubic feet have been initiated. Expansion of storage capacity is anticipated. Basic geologic factors and availability of subsurface information ...

Natural gas markets are incomplete due to physical limitations and low liquidity, but most valuation approaches for natural gas storage contracts assume a complete market. We propose an alternative approach based on indifference pricing which does not require this assumption but entails the solution of a highdimensional stochastic-dynamic optimization problem under a risk measure. To solve this...

Carvões ativados (CA) são caracterizados por elevadas áreas superficiais específicas e elevados volumes de poros. Os principais processos de obtenção destes materiais consistem na ativação de precursores com elevado teor de carbono, como por exemplo, o coque de petróleo (CP). Neste trabalho CP foi ativado quimicamente com hidróxido de potássio (KOH). O produto foi caracterizado por meio de adso...

Carbon Dioxide Storage in Natural Gas Reservoir — The general idea of CO2 disposal in gas reservoirs is that the underground volume of the ultimately recoverable hydrocarbons (gas and condensate) is replaced by CO2. This paper investigates the feasibility of carbon dioxide disposal in depleted gas reservoirs. Gas reservoirs are a practical storage site for the carbon dioxide, because the presen...

adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. carbon nanotubes can be introduced as a new candidate for natural gas storage. in this study, adsorption of methane was firstly studied on the as-prepared multi-walled carbon nanotubes, and then chemical and physical treatment of mwcnts was performed to enhance the methane adsorption...

Previous literature suggests that daily changes in US natural gas (NG) futures prices and their variance can be explained by oil volatilities, storage announcements, temperature shocks. These studies measure shocks using the National Oceanic Atmospheric Administration definitions of heating degree day (HDD) cooling (CDD). We show how hourly temperatures used to better long as well much depart a...
