Oil recoil - J Curve, page-25

As reported the over-production from the Saudi's must stop at some point in time. I assume that when they officially cut production the price will begin to rise again. As their main goal seem to be to drive the U.S. shale producers out of the game I wonder at which point they consider the U.S. producers cripple enough??

Is the lack of new wells, rig counts or lower production enough for the Saudi's to be satisfied, or are they waiting for the majority of U.S. shale producers to be bankrupt thus ensuring they can not resume producing any time soon. I suppose that there is no point in losing all the money for years an then having U.S. shale resume production a few weeks later.

Would anybody like to take a guess when this point would be reached??
