"Visualization of Methane Gas Hydrate Formation and Dissociation Using Micromodel"

 

Abstract

Understanding of Gas Hydrate formation, dissociation, and stability in the sediments are essential for modeling these systems both concerning global warming and in schemes of CH4 recovery and/or CO2 storage.

 

In this work, pore-scale visualization of CH4 hydrate, formation, and dissociation in sedimentary rock is carried out using the micromodel and image analysis.

 

The primary purpose of the research work is to visualize and evaluate CH4, hydrate formation, and dissociation containing different saturations.

 

Pore level visualization is carried out in transparent, etched, micromodel of sedimentary pores of a 2D thin section of the actual sandstone rock. Based on the micromodel experiment, the hydrate formation mechanism is visualized and discussed.

 

The effect of temperature and free gas in the system on dissociation is also studied and will be presented.
