Geologic summary report of the 1988 exploration program, Sunnyside Tar Sands project, Carbon County, Utah--volume 1

The 1988 field program focused on completion and logging of twelve core drill holes and three measured sections. Five marker beds were established within the Parachute Creek Member and include the Wavy Bedded Tuff, Mahogany oil shale, R-5 oil shale, lower tuff and Blue Marker containing the R-2 oil shale. The field season extended from June 7-0ctober 21, and included 104.5 working days. A breakdown of these working days includes 10.5 days for organization; 12.5 days for field geology; 17 days at the drill sites for coordination of dozer work, drillers, well logger and surveyors plus stopping the holes; 44.5 days for logging core and 20 days for travel. The weather was abnormally dry and road conditions were generally excellent. Exceptions include a 12" snowstorm on September 12, heavy rains on September 21, and rain with 4" of snow on October 12. The normal wet season that occurs in late Augustearly September did not occur in 1988. This report focuses on the results of the 1988 drilling program and is a continuation of previous exploration reports. Seven photographs included in this volume are used to highlight aspects of the Sunnyside Tar Sands project. Volume II contains seven large maps. Volume III contains fifteen strip logs. Both core logging and field work were used to determine the lithologic characteristics and environments of deposition associated with the Sunnyside Tar Sands deposit, and this data is summarized in Table 5. This field and core data was used in conjunction with the gamma ray well logs to correlate and determine numbered tar zones. The numbered tar zones and bitumen content (analyzed by Core Labs, Inc.) appear on the strip logs and in Tables 8 and 9. The use of numbered tar zones has established continuity between the field data and drill hole data throughout the Sunnyside Tar Sands area.
