It says it's 10 to 20 km below the ocean floor. Are we as humans been digging in the ocean floor that deep, or even at all? That sounds like sci-fi to me, I'd love to learn more if that's actually feasible.

Apparently the deepest oil well at sea was 10km deep, in the Mexico Gulf, drilled by the Deepwater Horizon rig
