I didn’t phrase my question very well in the above post.

What I meant to ask is how does one know that he has drilled into or through a pocket of methane hydrates?

They ain’t going to still be hydrates when they get back to the surface.

Is it possible that this happened in the case under discussion here?

What would happen IF you pumped a bunch of cement into a hydrate formation while cementing a casing string for instance?

Will the cement flow normally in that situation?

Could a large hydrate pocket screw up a cement job and especially if the cement were of the foamed variety?

While we're asking questions I have one, FAR outside what I know anything about. If you drill into frozen methane hydrate and run hot, setting, cement, will it “defrost” the methane and perhaps cause this?
