I found a way to get a Xeno to knock me through the end door of the refinery after the first lift. This may work with other doors, but as the corridor goes left, there's less chance you'll fall out of the map.

It does mean you need that one specific Xeno to come through the ventilation or it won't work. I was messing around and threw a flare, so it might be even quicker without it.

You can skip using the computer and waiting for Tequila to ramble on about Karl Bishop Wayland before you can leave.

It saves around 40 seconds.
