EIA Annual Energy Outlook 2018 – Reference Case 11
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
