Passing gas through the hydrate stability zone at southern Hydrate Ridge, offshore Oregon

We present an equilibrium model of methane venting through the hydrate stability zone at southern Hydrate Ridge, offshore Oregon. Free gas supplied from below forms hydrate, depletes water, and elevates salinity until pore water is too saline for further hydrate formation. This system self-generates local three-phase equilibrium and allows free gas migration to the seafloor. Log and core data f...

Formation Kinetics of Structure H Gas Hydrate

This paper investigates the kinetics of structure H (sH) formation kinetics above and below the structure I (sI) formation equilibrium curve at temperatures of between 2°C and 6°C. Methane was used as a help gas and methylcyclohexane (MCH) was used as sH former. It was concluded that in the points above the sI formation equilibrium curve, at the first, the sI forms, and then converts to sH be...

Investigation of the Hydrate Formation Equilibrium Conditions of Natural Gas

One of the main problems in oil recovery via the gas injection is the formation of hydrates in thelines. In order to prevent the formation of hydrate in these lines, which leads to the blockage andsometimes explosion, at first, the equilibrium formation conditions must be determined and then toprevent its formation by changing the thermodynamic conditions or by adding the inhibitors. In thisres...

Effect of Overpressure on Gas Hydrate Distribution

The effect of overpressure on gas hydrate and free gas distribution in marine sediments is studied using a one-dimensional numerical model that couples sedimentation, fluid flow, and gas hydrate formation. Natural gas hydrate systems are often characterized by high sedimentation rates and/or low permeability sediments, which can lead to pore pressure higher than hydrostatic (overpressure). To q...

Evaluation of Empirical Correlations for Predicting Gas Hydrate Formation Temperature

One of the important, practical and simple methods for hydrate formation conditionis empirical equations, and so far many empirical equations have been presented to predict thetemperature and pressure of hydrate formation. In this study, the methods and empiricalcorrelations have been reviewed and their predictive capabilities have been evaluated with ...
