second largest oil producer after the u.s. has declined to cutback oil production. is this aimed at pricing expensive to produce shale oil mostly from this country and canada and get identity out of the market lays. >> in some sense the saudis didn't have much of a choice. if they cutback production the u.s. was growing at a million barrels per day per year. the u.s. would keep growing and offset a lot of the saudi production cut. and the saudis aren't going do it alone they will do it with other members of peck and none-opec countries. they are trying to slow down the growth of u.s. shale but more so non-u.s. supply like the arctic, ultradeepwater, oil sands and that's work. $300 billion in global capital investment cutback. >> i want to just be clear on your biography. you're a former senior adviser
