I tend to use productivity modules exclusively outside of oil wells. Everything from Refineries to Assembly Machines to Electric Furnaces.
That is until I run out of power, and don't have the space to conveniently expand my solar... then I start not filling all the slots

Don't forget to cram as many 2 x Speed3 beacons around clusters of pumpjacks. More speed!

I actually don't do that when a beacon will only cover one well. I do place beacons at all the locations that they will cover more than one though.
If my oil supply isn't fast enough, the resources are much better spent on expanding to another oil patch, than on a bunch of beacons with a single recipient.
