Production costs of $50/bbl are not believable unless the oil boys are importing costs from other regions.  Alaska paying the Oil Barons to haul off this valuable non-renewable resource and they are still losing money?  If so, Why do we/they continue to try to pump Alaska dry?  If everybody is actually losing or barely breaking even, then shut it in until both a rational tax policy and price point are realized.  This immensely profitable industry can carry on with the necessary repairs & maintenance until all involved obtain a "Fair Share".
