Approaching a pressurized oil pocket

[QuQuasar]

I have a geyser that has spawned in the middle of a highly pressurized oil pocket. And I don't mean a normal pressurized oil pocket, I mean this monster, spawned as a result of a modified worldgen algorithm. At a guess I'd say there's about 10 times as much oil in this pocket as there should be, and it's a *big* pocket. 

So here's an engineering challenge: in survival, how do I enter an oil pocket with this much pressure without it exploding back up the tunnel and deep frying us all?

I'm currently leaning towards this old design, which I recently dug up and which I've never actually had an excuse to use in survival until now...

 

... but I'm open to suggestions. The mechanical waterproof airlock is cool, but it's also bulky and may be difficult to build in survival.

Just a normal v-lock would work perfectly, use doors instead of tiles and profit. It's only 90c so water would be fine ?

Crude oil is heavier than water, so wouldn't it just flow into the lock and displace the water? Unless I'm misunderstanding what you're suggesting.

One element per tile remember, 1 gram of anything (except maybe oil in this case  ) can stop any amount of oil providing it has nowhere to go.

I'll have to test it in sandbox mode. 

My expectation was that the pressurized oil would either swap tiles with the water, due to being heavier than it, or push it out of the way as it tries to expand into the space the water occupies.

The oil could (and most likely will) sink below the other liquid, as the two liquids will swap with crude falling below.  You can use an escher waterfall (two different gasses trapped), or even a similar contraption with several stacked liquids on a ladder directly down into the oil. Lots of fun ways to abuse the 1 element per tile mechanics.  Have fun playing.  Report what you find.

Seems simple enough

Good luck building with neutronium in survival though

Thanks for the tips folks, I guess I underestimated the quirkiness of the 1 tile per element mechanic, I really thought the pressure would just spit the water out.

In the end I took a mechanical approach, though. More fun to design, and I really liked how the airlock ended up connecting up perfectly with the existing ruins.

Won't that design break if a two dupes try to enter from both sides at the same time?

Nope. Unlike gasses, liquid flow in ONI isn't fast enough to push oil from one side to the other before the doors and gravity start forcing it down. I've not been able to break it in sandbox mode, even with multiple dupes running backwards and forwards through it.

 

The worst case scenario (it's never happened to me even in sandbox, but it's theoretically possible and I had to do it during construction) would be that two dupes stand in the airlock doors long enough for the central chamber and all 6 tiles of the door pump to fill with oil, causing the door pump to stay open indefinitely. If that does happen, though, it's trivial to fix: just flick the hydro sensor on and off manually a couple times to pump the oil out.

Right, liquid lock not gas lock.
