Numerical Investigation on Gas Hydrate Production by Depressurization in Hydrate-Bearing Reservoir

Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2016
Gas hydrates are anticipated to be a promising energy source with global distribution underneath the oceans and in permafrost regions. Hydrate dissociation referring to the phase transition of the solid gas hydrate into gas and liquid water, can occur due to altered environmental conditions like increase in temperature, decrease in pressure, or the ...

Experimental Characterization of Production Behavior Accompanying the Hydrate Reformation in Methane Hydrate Bearing Sediments

Canadian Unconventional Resources and International Petroleum Conference, 2010
Abstract The paper analyzed experimentally the production characteristics of hot-brine stimulation accompanying the hydrate reformation in the presence of methane hydrate. Many attempts have been to recover commercially the methane hydrate such as depressurization, thermal stimulation, and inhibitor injection.

Gas Hydrates: Occurrence, Production, and Economics

Proceedings of SPE Production Operations Symposium, 1991
Abstract Gas Hydrates – Occurance, Production and Economics Gas hydrates are crystalline compounds stable under particular conditions of low temperature and high pressure. Relatively large quantities of methane can be trapped in small volumes of hydrates, which represent a substantial in-situ natural reserve and ressource ...

Characterization of hydration products of mineral trioxide aggregate

International Endodontic Journal, 2008
AbstractObjective  To characterize the hydration products of white mineral trioxide aggregate (MTA).Methodology  Mineral trioxide aggregate, white Portland cement and bismuth oxide were evaluated using X‐ray diffraction (XRD) analysis and Rietveld XRD. The cements were tested un‐hydrated and after hydration and curing for 30 days at 37 °C.

Numerical Studies of Gas Production from Methane Hydrates

SPE Gas Technology Symposium, 2002
Abstract EOSHYDR2 is a new module for the TOUGH2 general-purpose simulator for multi-component, multiphase fluid and heat flow in the subsurface. By solving the coupled equations of mass and heat balance, EOSHYDR2 can model the non-isothermal gas release, phase behavior and flow of fluids and heat under conditions typical of common ...

Methane hydrates as potential energy resource: Part 2 – Methane production processes from gas hydrates

Energy Conversion and Management, 2010
Abstract Three processes have been proposed for dissociation of methane hydrates: thermal stimulation, depressurization, and inhibitor injection. The obvious production approaches involve depressurization, heating and their combinations. The depressurization method is lowering the pressure inside the well and encouraging the methane hydrate to ...
