Summary & Outlook  We are producing from sweet spots using primary production, similar to the oil industry of 100 years ago  Tight oil recovery factors are 5-10%  There is a large technology upside, which might include o State of the art well construction o New reservoir contact paradigms o Some form of enhanced oil recovery
