My understanding of methane under pressure is that it rapidly forms a heavy soft-crystalline structure that sinks. It is entirely stable at the temperatures that are found below 4-500 feet (150m).

So, any methane that isn't transported by rising oil to the daylight zone is unlikely to provide a problem for us in this geological cycle.

As TBG says, the accelerating release of the Siberian clathrates are the problem we're facing right now.
