The fastest, easiest way to solve the issue is to blend our light crude with heavy crude to have something usable in our refineries.
The cheapest, fastest and safest way to move oil is through a pipeline. The most geopolitically stable supplier of heavy and super heavy crude oil is just north of our border. Canada. The pipeline that was meant to bring their crude, the keystone pipeline was cancelled after its permits were revoked.
The con of Canadian oil is that some of it is produced by Steam Assisted Gravity Drain, a process were steam has to be injected into the reservoir to heat up and reduce the heavy oil’s viscosity, allowing it to drain into a horizontal well, drilled closely below the steam injecting well. This is an energy intensive process, and if the energy to produce the steam is derived from fossil fuels, it’s carbon footprint is large.
Another potential suppliers of heavy crude is Venezuela, but it’s dictatorship has mismanaged the industry to the point that they are importing crude and distillates.
There are no solutions, only trade offs.
