Key Points
• Natural declines in oil & gas fields mean significant volumes of new supply need to be brought online every year to keep up with global energy demand
• The world still gets more than 80 per cent of its energy from fossil fuels, despite trillions of dollars of investment into renewables
• Some Canadian oil sands projects have near-zero decline rates, making them an ideal source of supply for as long as the world needs oil

We don’t talk about oil and gas depletion rates very much. It is a discussion worth having, especially considering that half a Saudi Arabia’s worth of oil production – about 6 million barrels per day – needs to be brought online every year to replace declines in current global supply [1]. This also translates to more than an entire Canada’s worth of new oil production annually just to keep global oil supply flat.
But how do these declines in existing oil and gas fields happen anyway?
