The increasing U.S. energy demands, decreasing conventional crude oil reserves, and decontrol of crude oil prices have resulted in significant numbers of projects in U.S. tar sands. Data are reported for 62 projects involving in situ, mining and plant extraction, modified in situ and upgrading technologies. The data include operator name, project location, project status (completed, current, or planned), project type (commercial or pilot), reservoir and oil characteristics, and estimated product costs. The cost estimates per unit of produced oil provide encouragement of the commercialization of the U.S. tar sand resource.
