Factorio currently comes with two campaigns, "First Steps" (3 levels, the tutorial) and "New Hope" (4 levels), for a total of 7 levels. (Internally, these are called "demo" and "beta".)

It also has the Scenario Pack, which contains two more "side campaigns", Transport Belt Madness (3 levels) and Tight Spot (5 levels) -- giving you a grand total of 15 levels.

I omit water requirement as not important.

Should you crack oil?

You can transform 2 heavy, 2 petroleum or 1 light to 1 solid fuel.
You can crack oil products: 4 heavy → 3 light → 2 petroleum.

Heavy oil gives you 0.5 solid fuel per heavy unit. Heavy cracked to light gives you 0.75×1 = 0.75 solid fuel per heavy unit.

Light oil gives you 1 solid fuel per light unit. light cracked to petroleum gives you 0.66×0.5 = 0.33 solid fuel per light unit.

Result: You should crack heavy into light, but avoid cracking light into petroleum.

Basic or advanced oil processing?

Best values you can get per oil product unit: heavy → 0.75 solid fuel, light → 1 solid fuel, petroleum → 0.5 solid fuel

Basic oil processing gives 3 heavy, 3 light and 4 petroleum per 10 crude.
Advanced oil processing gives 1 heavy, 4.5 light and 5.5 petroleum per 10 crude.

Total solid fuel per 10 crude:

• Basic oil Processing: 3×0.75 + 3×1 + 4×0.5 = 7.25 solid fuel
• Advanced oil Processing: 1×0.75 + 4.5×1 + 5.5×0.5 = 8 solid fuel

Result: It is better to use Advanced Oil Processing to maximize solid fuel yields.
