“…For example, in laboratory experiments conducted with a well sorted natural sand with an average grain size of 0.75 mm, deBoer et al (1985) observed that only 50% of the available pore space was filled with hydrates. Hydrate saturation values of less than 50% are often cited in the literature (Kamath, Godbole et al 1987;Goel, Wiggins et al 2001). Additionally, not only are the pore spaces in naturally occurring systems often unsaturated with respect to hydrates, but the hydrate structures themselves are often unsaturated with respect to gas.…”

Natural-gas hydrates have been encountered beneath the permafrost and considered a nuisance by the oil and gas industry for years. Oil-field engineers working in Russia, Canada and the USA have documented numerous drilling problems, including kicks and uncontrolled gas releases, in Arctic regions. Information has been generated in laboratory studies pertaining to the extent, volume, chemistry and phase behavior of gas hydrates. Scientists studying hydrates agree that the potential is great-on the North Slope of Alaska alone, it has been estimated at 590 TCF. However, little information has been obtained on physical samples taken from actual rock containing hydrates.This gas-hydrate project is a cost-shared partnership between Maurer Technology, Anadarko Petroleum, Noble Corporation, and the U.S. Department of Energy's Methane Hydrate R&D program. The purpose of the project is to build on previous and ongoing R&D in the area of onshore hydrate deposition to help identify, quantify and predict production potential for hydrates located on the North Slope of Alaska.

“…Considering the planet as a whole, the quantity of natural gas in sedimentary gas hydrates greatly exceeds the conventional natural gas resources 3 . A variety of different mechanisms have been proposed for economically developing gas hydrates as an unconventional gas source (e.g., see discussions in Goel et al 13 , 2001, Sawyer et al 14 , 2000, among others). Thus far, the only method that has been successfully used to economically produce gas from gas hydrates is the "depressurization method".…”

Gas hydrates sediments have the potential of providing a huge amount of natural gas for human use. Hydrate sediments have been found in many different regions where the required temperature and pressure conditions have been satisfied. Resource exploitation is related to the safe dissociation of the gas hydrate sediments. Basic depressurization techniques and thermal stimulation processes have been tried in pilot efforts to exploit the resource.There is a growing interest in gas hydrates all over the world due to the inevitable decline of oil and gas reserves. Many different countries are interested in this valuable resource. Unsurprisingly, developed countries with limited energy resources have taken the lead in worldwide gas hydrates research and exploration.The goal of this research project is to collect information in order to record and evaluate the relative strengths and goals of the different gas hydrates programs throughout the world. A thorough literature search about gas hydrates research activities has been conducted. The main participants in the research effort have been identified and summaries of their past and present activities reported. An evaluation section discussing present and future research activities has also been included.

Replacement of CH₄ in Hydrate in Porous Sediments with Liquid CO₂ Injection

The dynamics of the replacement of CH4 in hydrate in porous sediments with liquid CO2 was investigated using a self‐developed experimental apparatus at different temperatures and initial pressures. The pressure increases steadily as the replacement reaction processes. The amount of the replaced CH4 is almost the same as that of the CO2 forming hydrate in the early stage and gradually becomes somewhat less in the later stage. The initial pressure has minor effects on the replacement rate, and temperature reduction causes a lower replacement rate. The experimental results suggest that the replacement rate is not related to the region of the temperature‐pressure conditions but is mainly affected by the fugacity differences of CH4 hydrate decomposition and CO2 hydrate formation.
