In situ recovery projects in the Northwest Asphalt Ridge (Utah) tar sand deposit

Technical Report ·
OSTI ID:6320227
; ; ; ; ; ;
The Laramie Energy Technology Center (DOE) conducted three in situ recovery projects in the Northwest Asphalt Ridge (Utah) tar sand deposit. These projects included: a reverse-combustion project (TS-1C), a reverse/forward-combustion project (TS-2C), and a steamflood project (TS-1S). The chemical and physical properties of the oils produced during these three projects have been determined and these properties have been related to the method of production. The majority of the oil produced by the first combustion project (TS-1C) was quite similar to the original bitumen. This was because the highest temperature observed during the project was only about 177/sup 0/C (350/sup 0/F). However, the second combustion project (TS-2C) produced a total oil significantly improved in fuel quality with respect to the bitumen. The reason for the observed improvement in the produced oil is that this project experienced higher, more widespread temperatures (>538/sup 0/C (>1000/sup 0/F)); thus, resulting in more extensive thermal cracking of the original bitumen. The properties of the oil produced during the steamflood project (TS-1S) were very similar to those of the original bitumen. This was because after the viscosity of the bitumen was reduced by the injection of steam, the bitumen was then produced to the surface by a hot-water drive mechanism. 12 refs., 4 figs., 8 tabs.
