... Abstract Gas hydrates are acquainted as a significant topic to the oil and gas flow assurance, as it creates pipelines occlusions. The formation of gas hydrates can create many functional issues such as: stop of production, high preservation expenditures, environmental dangers and even loss...

... Abstract CO 2 exchange method is one of the extraction techniques that is under development for the production of methane from gas hydrate resources, and the mechanisms and kinetics of the CO 2 -CH 4 exchange process still remain unclear. We model this process with molecular dynamics (MD...

... Abstract India with the largest gas hydrate deposits in the world have potential of being the biggest global producer of NGH (a solidified form of gas lying on oceanic floors). 1.08 trillion cubic metres of the proven conventional natural gas reserves in India is around 1700 times less than...

... Abstract Gas hydrate is a crystalline solid consisting of gas molecules, each surrounded by a cage of water molecules. They produce 160 times their volume of methane which is an infinite source of energy waiting to be tapped, but the technology to recover these hydrates is at its infancy...

... Abstract As hydrocarbon exploration and development moves into deeper water and onshore arctic environments, it becomes increasingly important to quantify the drilling hazards posed by gas hydrates. To address these concerns, a 1D semianalytical model for heat and fluid transport...

... Abstract The main components in producing natural gas hydrate (whether for gas storage or for transportation), are water and natural gas, at low temperatures and high pressures. Each variable has a significant effect on the formation of gas hydrate. It is therefore critical to analyze...

... issue for many countries. Natural gas is a much cleaner fuel than oil and coal especially for electricity generation. Interest in gas hydrate being used as a means of transporting natural gas has increased over the last decade. New technology development has been focusing on using gas hydrates as a way...

... Recovery of gas from hydrates requires the dissociation of the hydrates by changing the thermodynamic conditions to a state where the hydrate phase is unstable. Dissociation of gas hydrates can be accomplished in at least three ways. The first method is thermal stimulation , the second...

... crystals and even nuclei, while there is no sign of hydrate formation from monitoring system pressure. The results are very encouraging and could potentially change the industrial approach to gas hydrate control strategy. This work is part of a comprehensive project which covers monitoring the degree...

... Abstract Natural gas hydrate (NGH) technology is an attractive alternative to capture associated gas on FPSO's to solve the stranded and marginal gas problem in the oil industry. Based on estimates for land-based plants, the capital cost of hydrate technology is considerably lower than LNG...
