How Scottish oil could reshape British war power

How would Saudi-scale oil reserves discovered in Scotland during the 1920s affect the Second World War?

Britain would gain enormous wealth and domestic energy security, reducing tanker and import burdens while accelerating rearmament, mechanization, industrial output, and operational flexibility.

Saudi-scale Scottish reserves would reduce vulnerable tanker voyages and give Britain a secure domestic fuel supply. Oil revenue could ease the effects of the Depression and provide more money for rearmament. Synthetic rubber, mechanization, civilian transport, and food distribution would also benefit from abundant energy. The result would be a different wartime economy with greater freedom to sustain ships, aircraft, and land forces.
