I have a few questions about oil production

[Heisenberg]

Hello, I have a few questions about oil production:

Oil platform: what does 80% well quality mean exactly?
Production of 7 tons of oil per day would then only be 3.5 tons at a quality of 50%, or how is that calculated?

Oil refinery: Consumption at max. production. Is that per day?
With 500 workers, that would be 250 tons of oil, 125 tons of fuel or 75 tons of bitumen per day. Example with 50 workers 25 tons of oil and with 5 workers 2.5 tons of oil?
What does oil tank (import) 450 t oil or oil tank (export) 340 t fuel, oil tank (export) 250 t bitumen mean?

Oil power plant: 15 workers produce 1050 MWh, so 5 workers a third? So then only a third of the 8.8 t oil consumption per day
What does oil tank (import) 200 t oil mean?

Many thanks for your help

Yes, all that are correct.
Tank import/export means that the building has internal storage. On one hand, you can deliver up to 450t oil to not working refinery. On the other hand, refinery can work even if you do not transport out produced products, while export tanks have space to store bitumen and fuel.

For any mined resource, the expected output is the maximum daily production times the source quality, provided the facility is working with maxed inputs. For your 80% source quality pump jack in this instance, you should expect 5.6 tons of oil a day from it, provided you can meet its energy needs.

Effectively, you can think of "quality of source" as simply how efficiently the facility can produce the output for the inputs. Also, production rates are always listed as per day.

Factories and refineries production rates seem to be like a bell curve when it comes to employment. Most facilities will not function at all with only a couple of workers (some need both university educated and basic educated workers to work), whereas maximum production rate will be achieved with less than maximum workers. Keep in mind that citizen productivity will also influence this.

Power plants and heating plants seem to work at 100% so long as they have more than a set percentage of their maximum workforce; below that, it probably won't be working. This is hard to notice with low heat/power demand.

Facilities with internal storage can pull/push to other directly connected storage. Export means it will push the goods to other storage that can accept the goods to the point that there is an equal percentage of the goods in each storage (for example, a food factory that made 70t of food will push 65t of food into a sole adjacent warehouse and keep 5t of food in its storage; both are at 20% of their respective storages). Import is similar, but works in reverse. Storage marked neither export nor storage, will just hold its goods.

There are some exceptions (vehicle production lines will not push their production to connected vehicle/container storage yards unless their internal (export) storage is filled).

There are also "pumps" like liquid pumps for oil, conveyor engines for aggregates, and forklifts/trucks for general goods. These "pumps" will ignore storage behavior and move goods from an input storage to an output storage.

Direct connections can also be used pull/push goods, but it seems to affect production rates of some facilities, notably the container packing facility.

Thank you very much for the great explanation, you really helped me

You're welcome.

I also noticed that and thought I was crazy, but it does make sense to not have linear productivity based on active workforce. Cheers for sharing all this arcane knowledge. I wonder whether it wouldn't be wise to start some sort of Wiki (on fandom.com or some other public wiki site) and collate all such interesting information. I remember another user moa who used to share very intricate and arcane information regarding citizen logic.

All this tribal knowledge known just by a few deserves to be publicised.

a really great idea I just can't do something like that

Now that I read it again, I think a logistic or logarithmic curve would be more accurate than a bell curve (which implies the production rate declines with too many people).
