There is a big problem with counting the Chevron Oil strike in the Gulf of Mexico because of its depth. This hit that is estimated to be large is also inaccessible using current equipment. Chevron and two other companies had to go 7,000 feet below the warm water layer of the Gulf of Mexico, and then drill miles below the sea floor for a total depth
of 28,175 feet. For comparison this is cruising altitude for an airliner, compare that depth to the 69 foot depth of the first commercial oil well in the USA. We need to first design and build tools that will let us design and build the drilling equipment needed. Let us say around ten years in the good side to get this alleged huge deposit running. The dry tundras in Canada are no picnic either since the oil production is dependant on ability to supply water and heat to the shales and tars. The easy oil is running out.
