Title: Experimental in situ retorting of oil shale at Rock Springs, Wyoming

Technical Report ·
OSTI ID:6541601

Preliminary results of an in situ oil shale retorting experiment conducted by the U.S. Bureau of Mines in a shallow bed of Green River oil shale at Rock Springs, Sweetwater County, Wyoming are described. Eleven wells were drilled into a 20-ft-thick section of the shale lying between 68 and 88 ft deep, and attempts were made to connect the wells through the shale with a fracture system created by application of high-voltage electricity (electro linking), hydraulic fracturing, and explosive fracturing. Ignition of the shale through the central well was easily achieved with a propane burner, and shale oil began to collect in 3 wells within 3 hr. Propane injection was discontinued after 7 days, and combustion continues, although attempts to control the direction of the combustion front have been unsuccessful. Production rates as high as 4-1/2 bopd have been recorded, but too little is known about underground conditions to permit an estimate of recovery efficiency at this time.
