Follow-up on the previous article, this one from Arthur Berman for Naked Capitalism :
Prolonged low oil prices will prove that tight oil plays need at least $75 per barrel to break even. When oil prices recover to that level, only the best parts of the tight oil core areas will be competitive in the global market. As production declines from expensive tight oil, oil sand and ultra-deep-water plays, inexpensive Saudi oil will gain market share.
Saudi Arabia is not trying to crush tight oil plays, just the stupid money that funded the over-production of tight oil. Too much supply combined with weak demand created the present oil-price collapse. Saudi Arabia hopes to prolong low prices to benefit their long-term needs for market share and higher demand.
