Great mod, I used it for a no mining scenarios but can up hard against the fact that there is no recipe for oil. It would be appreciated to add a recipe from ore to crude oil.

If you want a recommendation for ratios I would say 1 iron/copper is 10 crude oil with a 50% reduction for alien ore 2. IE AO1 cannot turn into oil, AO2 would turn into 5 crude oil, AO3 would turn into 20 crude oil and alien artifact would turn into 50 crude oil.
If you want a different ratio that works too, i just want to be able to convert alien ore into crude oil

Sure, it is a good point. I will include conversion to crude oil in next update.
I did not include that because I thought other ores are finite, but crude oil is infinite. But then I missed the case if there are no oil wells at all.

Yes, I appreciate recommendations, a lot. :-) It is much better than having me to try out a solution all by myself.
I have a "desired" value ratio of 1:2:4:10 between AO1:AO2:AO3:AA. And your suggestion sounds fitting perfectly.
I will try and test that a bit before releasing.

thanks

Just tested and made some calculations. I feel your value set is too favourable.
So I nerfed that and now testing 1 AO2 → 2 (Crude) Oil, 1 AO3 → 8 Oil, 1 AA → 20 Oil.

I based this on what can be done with one AO3 (as 1/s AO3) in rate can be converted to.
An electric mining drill (EMD) has base speed 0.5/s on normal ores + coal.
A pumpjack (PJ) has base speed 10/s on a "standard" oil well; or 2/s on a depleted 20% oil well.
1/s AO3 → 2/s Coal (or iron ore, copper ore), which is equivalent to 4 EMD.
1/s AO3 → 8/s Oil, which is equivalent to 80% overall yield, or as 4 PJ on depeleted wells.
So these corresponds to 4 miners each, somewhat comparable.

Using 1/s AO3 → 20/s Oil, it is equivalent to 200% overall yield, or 10 PJ on depleted wells. Guess it is too much.
(Especially as I take the reference of many late-game bases, where factories usually have much more EMD than PJ. So 1/s AO3 → 20/s Oil will overproduce oil a lot.)

If things go smooth, I will publish the update on Thursday. Crafting time options will be included too.

Just publish 0.17.7, hope the feature is useful to you.
