Book Description
Hydrocarbon production in the Bluebell field is from three reservoirs in the Tertiary-aged Colton and Green River Formations: (1) overpressured Colton/Flagstaff, (2) lower Green River, and (3) upper Green River. Kerogen-rich shale and marlstone deposited in marginal and nearshore openlacustrine environments are the source of the waxy crude in the Colton/Flagstaff and lower Green River. Marlstone, or oil shale and possibly coal, are the sources for the asphaltic crude found in the upper Green River. Non-associated gas in the upper Green River could be from coaly deposits in the upper Green River, or migrated up from the lower Green River, or a combination of both. The lithology of all three reservoirs is similar; fractured sandstone, shale, limestone, and marlstone beds having generally low intergranular porosity and permeability. The strata were deposited in lacustrine and alluvial environments.

Book Description
The objective of this project is to increase the oil production and reserves in the Uinta Basin, Utah, by demonstration of improved completion techniques in the Bluebell field. Low productivity is attributed to gross production intervals of several thousand feet that contain perforated thief zones, water-bearing zones, and unperforated oil-bearing intervals. Geologic and engineering characterization and computer simulation of the Tertiary Green River and Wasatch Formations in the Bluebell field will determine reservoir heterogeneities related to fractures and depositional trends. This phase will be followed by drilling and recompletion of several wells to demonstrate improved completion techniques based on the reservoir characterization. Transfer of the project results will be an ongoing component of the project. Technical progress is described for: outcrop studies of the Green River Formation; subsurface studies of the Bluebell field; and engineering studies of the reservoirs in the Green River Formation and the Wasatch Formation.

Book Description
Wells in the Bluebell field are typically completed by perforating 40 or more beds over 1,000 to 3,000 vertical ft, them stimulating the entire interval with hydrochloric acid. This technique is often referred to as the shot gun completion. The shot-gun technique is believed to leave many potentially productive beds damaged and/or untreated, while allowing water-bearing and low-pressure (thief) zones to communicate with the wellbore. A two-year characterization study involved detailed examination of outcrop, core, well logs, surface and subsurface fractures, produced oil-field waters, engineering parameters of the two demonstration wells, and analysis of past completion techniques and effectiveness. The study was intended to improve the geologic characterization of the producing formations and thereby develop completion techniques specific to the producing beds or facies instead of a shot gun approach to stimulating all the beds. The characterization did not identify predictable-facies or predictable-fracture trends within the vertical stratigraphic column as originally hoped. Advanced logging techniques can identify productive beds in individual wells. A field-demonstration program was developed to use cased-hole advanced logging techniques in two wells and recompletion the wells at two different scales based on the logging. The first well was going to be completed at the interval scale using a multiple stage completion technique (about 500 ft per stage). The second well will be recompleted at the bed-scale using bridge plug and packer to isolate three or more beds for stimulation. These recompletion will show which logs are most effective in identifying productive beds and what scale of completion is most cost effective. The third demonstration will be the logging and completion of a new well using the logs and completion scale or technique most effective in the previous demonstrations.
