Here is what I use for my Oil Production Rules. They add bonus income which can be used for Research and Development, Purchasing more units, and Infrastructure development if desired. As a note I use the Global War 39 XL map in my games so some of the territories would need to be adjusted for an A&A Global 40 Map. I generally use the Bonus income for Research and Development to help build up my R&D Labs early in the game. This way I have a good chance getting some really helpful technologies mid game.

Oil Derricks and Refinery Rules
#1. These units are fixed at game start and can’t be moved.
#2. These units can be strategically and tactically bombed. Three hit points renders these facilities inoperative.
#3. If the oil producing territory is captured it takes 2 turns for an Oil Derrick to start producing again and 3 turns for a refinery to produce again. The turns to full production are represented as hit point counters placed under facility same as other bombed facilities.
#4. Domestically produced Oil with a clear supply route to the Capital via land or Sea is produced at full production. However Domestic or Foreign produced Oil that doesn’t have a clear supply route to Capital is reduced to half capacity. The Exception is a territory with only an Oil Derrick or Refinery which will have no point value for that turn and again until a clear supply route is obtained.
