From: Effects of interactions in natural gas/water/rock system on hydrocarbon migration and accumulation
The snapshots during the gas migration and accumulation process in the sand body. The blue represents the higher water saturation, and the green represents the higher gas saturation. When the natural gas migrates into the sand body from the bottom edge, the water mainly distributes in the upper part of the sand body. After a long geological history, the water mainly distributes at the bottom of the sand body.
