(Skolkovo Institute of Science and Technology (Skoltech)) Researchers from Skoltech have designed and conducted experiments measuring gas permeability under various conditions for ice-containing sediments mimicking permafrost. Their results can be useful both in tracing methane emission in high latitudes and in modeling and testing techniques for gas production from Arctic reservoirs.The study also showed that the dissociation of gas hydrates can lead to permeability increase. This, in turn, will lead to methane emissions into the atmosphere, causing a variety of environmental and technological impacts.
