How much oil is left in the oil sands?

Published in Oil Sands Resources 2 mins read

As of current estimates, 161 billion barrels of oil are considered economically recoverable from the oil sands using existing technology.

Understanding Oil Sands Reserves

The vast oil sands deposits contain a significantly larger amount of oil in total, but only a fraction of it can be extracted and processed economically with current methods. This distinction is crucial when discussing the overall resource versus what is practically available.

Here's a breakdown of the estimated oil quantities in the oil sands:

Category Estimated Quantity Description
Total Oil in Place 1.8 trillion barrels The entire estimated volume of oil contained within the oil sands deposits.
Economically Recoverable Less than 10% The percentage of the total oil in place that can be extracted profitably with current technology.
Recoverable Reserves 161 billion barrels The calculated amount of oil that is considered economically viable to recover.

Why Aren't All Barrels Recoverable?

The challenge in extracting oil from the oil sands lies in its form. Unlike conventional crude oil that flows easily, oil sands bitumen is a very heavy, viscous form of petroleum. Recovering it requires energy-intensive processes, such as mining or in-situ (in-place) methods that involve injecting steam to reduce viscosity and allow flow.

Several factors influence what is deemed "economically recoverable":

  • Technology: Current extraction technologies have limitations in terms of depth, type of deposit, and efficiency. Advancements in technology could potentially increase the recoverable percentage in the future.
  • Economic Viability: The cost of extraction, processing, and transportation must be less than the market price of the oil to be considered economically recoverable. Fluctuations in global oil prices significantly impact this viability.
  • Environmental Considerations: The energy and water intensity of oil sands extraction, along with associated greenhouse gas emissions, contribute to the overall cost and feasibility, and influence regulatory frameworks.

The 161 billion barrels represent the current estimate of the portion of this immense resource that can be effectively brought to market under existing technological and economic conditions.
