Title: Recent government efforts regarding tar sands

Journal Article · · Interstate Oil Compact Comm. Com. Bull.; (United States)
OSTI ID:6717973

Conclusions from a workshop on tar sands are discussed. The workshop participants came to 3 conclusions: any oil-impregnated rock that is mined or quarried and then processed on the surface should be considered tar sands; some physical parameter should be used to differentiate tar sands from heavy oils, e.g., viscosity; and the dividing line between tar sands and heavy oil should be a point above which there is not currently significant commercial production. The resulting definition states that tar sand is any consolidated or unconsolidated rock other than coal, oil shale, or gilsonite, that contains a hydrocarbonaceous material with a gas-free viscosity, measured at reservoir temperature, greater than 10,000 cp, or contains a hydrocarbonaceous material that is extracted from the mined or quarried rock. Some consideration of resuming tar sands leasing also is discussed.
