I think its great idea . Im mad when i have to find new resources of oil and then build whole new rafinery etc.We can have wagons whuch will transport oil to our base and we can process it there.We would need an extractor which will extract fluid from special wagon for pipes...
Until an official solution is added, there have been several solutions done via mods.
As part of my Logistics mod, several fluids can be stored in barrels, or bottles of some sort, which are items that can be transported, and unpacked at the other end, but my mod adds a lot more than just this, so it might not be for you.
There is also a tanker wagon mod that adds, basically what you're asking for. I don't have a direct link to it, but go look in the mods section.
Hope that helps.
