Sedimentary layers and gas migration pathways

Description

In this conceptual model, gas cannot easily reach the sediment surface of the continental slope without being transformed to gas hydrates or diverted upslope by impermeable hydrate-bearing sediment or glacial debris flows. Instead, gas migrates up through faulted sediment and upslope through permeable layers before reaching the sediment surface in the gas-flare region near the top of the continental slope.
