Alberta alone is producing as much oil from sands as Texas is from traditional deposits:

Production in Alberta is up 61 percent over the past four years. This year, Alberta's oil sands are expected to produce 1.2 million barrels a day, roughly equal to the production of Texas.

But now that oil is $70/barrel the oil sand oil probably costs $100/barrel. Still infeasible.

This year, Alberta's oil sands are expected to produce 1.2 million barrels a day, roughly equal to the production of Texas.

An "infeasible" technology producing that much oil?

What is your definition of "infeasible?"
