The science rework is something I am really looking forward to! I feelt like the gab between level 2 and level 3 science is too big since I was a beginner. However I think the reason for this is different. The complexity of blue science is only a little bit too high. Mainly the filter inserters are a pain for the science pack 3, because they take a HUGE amount of ressources already and require the player to expand on ressource production heavily in addition to the complexity of the oil production.
So let us think about what the basic idea of the science pack 3 is. This is easy: Force the player to get into oil. And this is already hard enougth! No need to force him to increase heavily on ore production as well. That would be 2 steps at once. So to me it seems to be a smart idea to focus on oil only for this pack and keep the production cost a little lower instead.

The last one shows a possible reciept that focusses on oil completely, and reduced complexity slightly.
In general i think the science should less focus on very high ore cost's, but increased complexity.

Pumpjack is too easy to accomplish but very ressource intensive, also it's vintage tech at this point. How about the stack inserter instead? It adds a nice production chain and therefor complexity without ending up with astronimic ore cost's

Copper wires and batteries dont really fit into "hightech". Maybe an Accumulator instead? 3 Processing Units are really taking a long time. Personally i think 1 should be fine already, but 2 seem reasonable as well.
However in general i really like the idea overall! Good job there!
Still, I Hope I could explain my points reasonable and hope my feedback get heared in some way
