If Africa do have a lot of oil reserves then it'll probably come from them. There were rumours of building a rail way under the sea between Gibraltar and Morocco a while ago, pipes for carrying gas would be easier to place and if the EU are serious on sanctioning Russia then it'd probably be worthwhile to sponsor those countries and provide them infrastructure.

There might also be attempts to increase the number of rigs there are for companies like bp and Shell to be able to extract more oil (the UK government has a habit of nationalising/buying things when the private sector makes them too expensive too which might be another thing that happens).
