')Then I came across this report from a USGS employee; this paper was never released by the USGS, because Leigh Price passed away before it could be finalized. Leigh Price's paper is, in my opinion, the definitive study on the amount of oil in the Bakken shale formation.
He estimated that there was 400 to 500 billion barrels of oil in the Bakken. There is a summary of the various Bakken estimates of oil in place (.pdf) on the North Dakota state website. If you figure the industry could produce 4% to 6% of this oil that is in place, this would put the producible oil at 16 billion to 30 billion barrels of oil just in the Bakken.
Therefore, after going through all this data and assigning estimated barrels of oil to various basins and shale oil plays plus including an estimate of yet to be discovered shale oil, I came to an estimate of oil in place. This estimate was also influenced by Leigh Price's paper on the Bakken. My estimate of oil in place in the continental US is from about 3 trillion to 5 trillion barrels of oil not including the 3 trillion barrels of oil shale. See this shale play website for a partial list of Shale oil plays and basins in the US. I know this seems very high, but it was only a few short years ago that we were going to need to import huge amounts of liquefied natural gas to meet our demand for natural gas, and now we have a glut of natural gas in the market place because of all the shale natural gas.
We should be able to produce at least 150 billion barrels of oil to maybe 1.0 trillion barrels of oil if the majority of these plays can be water flooded and CO2 injected as in the Canadian Bakken. I used 5% for the low estimate of 3 trillion barrels and 20% of the high estimate 5 trillion barrels figuring they could do some water flood and CO2 tertiary treatment to a large part of this land. For this oil to be recovered, it will require that the oil price stays above $70 a barrel so the economics are in place to fully develop these areas. We need to have some university professors in geology do some research instead of a retired, former CPA on this matter, because it becomes very important for the nation to determine what is a good projection of possible oil production.
