Characteristics of tar sand bitumen asphaltenes and the effect of asphaltenes on conversion of bitumen by hydropyrolysis | Asphaltenes derived from tar sand bitumen are similar to petroleum derived asphaltenes in that the geochemical history is similar for these sources. It has been shown that tar sand bitumen possesses an unusually high average molecular weight when compared with petroleum residues of similar initial b... | tar sand bitumen asphaltenes; characteristics of tar sand bitumen; effect of asphaltenes; bitumen conversion; hydropyrolysis; tar sand bitumen | 1979 |

Radio-frequency heating to recover oil from Utah tar sands | The IITRI RF Process for tar sands consists of two steps: first, the deposit is volumetrically heated with radio frequency energy to lower the viscosity of the bitumen; and the second, the bitumen is produced by one of several petroleum recovery methods. The RF (radio frequency) heating step is acco... | IITRI RF Process; Utah tar sands; oil recovery; raidio-frequency heating; heavy crude | 1979 |
