Overwhelmed with Oil

So I am finally trying to build something in Blue Crater. I have 6 oil lines in the following manner:

600/min

300/min

150/min

600/min

600/min

300/min

I took the bottom 300 and ran it to 4 refineries triple shard making 50 plastic and 25 residue.

These 4 then go to 2 constructers making 100 empty canisters (x2) a minute with the plastic.

Those then go into 2 packagers with water making 200 packaged water a minute.

Finally it ends at 2 refiners making diluted packaged fuel at 90 a minute which then outputs to a depot and sink.

This is 1 line and I'm overwhelmed as hell. What do I do with all of the lines and is this one a dumb waste? I'm super overwhelmed and could use some guidance as I'd love a highly efficient oil field.
