Characteristics of the PR Spring Tar Sand deposit, Uinta Basin, Utah, U.S.A. | The Laramie Energy Technology Center (LETC) conducted a seven-corehole drilling program in the PR Spring tar sand deposit, southeastern Uinta Basin, Utah, during the summer of 1980. Three main tar sand zones in the southwestern and west-central portion of the deposit were correlated by cross section... | 1984 | |

Pilot plant recovery of bitumen from oil-wet tar sands | The world's tar sand deposits appear to be divided into two basic types, characterized by the way in which the tar and sand are associated within the ore structure. In the first, the tar or bitumen in the ore is separated from the silica sand grains by a film of water. These sands are designated wat... | tar sand deposit; ore structure; bitumen; Enercor | 1982-02-17 |

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 |

Influence of chemical factors on primary processing of Utah tar sand bitumen | Research of recovery and processing technology applicable to Utah tar sands is currently in progress. Development of this hydrocarbon resource has not yet occurred, principally because of high costs associated with present recovery methods. The processing of bitumens is also expected to be relativel... | chemical factors of processing tar sand bitumen; Utah tar sand bitumen; tar sand bitumen; primary peocessing of tar sand bitumen | 1978-01-01 |

A preliminary estimate of world heavy crude oil and bitumen resources | Since the First International Conference on the Future of Heavy Crude and Tar Sands was held in Edmonton, Alberta, Canada, in June 1979, several significant events have occurred bearing upon future development of these resources. Positive factors include the following: (1) a second conference was he... | 1984 |
