Yes, anything that flows can technically be called a stream. Even if it flows a few inches every million years.
Nobody that I know of would describe an oil-charged rock as a pond.
Once the oil comes forth to see the sun what is the projected recovery rate with todays technogoly? If I remember correctlly it used to be said that we only recovered something like 15 % or so of the oil from the well. The remainder stayed down hole.
What's the price/bbl needed to make steam injection a viable recovery method today?
