RE:RE:US rigs drop 15 down to 555In general you are right but the devil is in details. US shale was estimated to have a capability to produce oil for 200 years, it all comes down to price and effort. Where we know shale is not profittable long term, however it will be used by the US governement to save petrodollar. They utilize many different tools to motivate oil producers to produce unprofittable oil. I wouldn't discount Permian at least yet.
