#Shale oil production improved US self Sufficiency. As well, they cut the Saudi off from traditional access to the gulf refinery; a hard hit for the @Saudi's. This left the Saudi fighting a 2 front price ware. #Primary was the @Chinese Indonesian gas plants who were selling LNG into the Saudi market at extremely low prices forcing the Saudi into a BTU war rather than an oil price war. Politics and embargo put the Russian Gazprom head on with the Saudi in the same market place. Hit from 3 sides they are/were in dire straights.
