to create void space Recent technology advances are expected to improve the viability of oil shale technology, leading to commercialization Of importance in the in situ processing option is the characteristic that oil shale is relatively hard impermeable rocks through which fluids will not flow Also of interest is the specific gravity of the oil shale since much of the inorganic material must be disposed The specific gravity of the Green River kerogen is approximately 105 and the mineral fraction has an approximate value of 27 (Baughman, 1978) In situ processes can be technically feasible where permeability of the rock exists or can be created through fracturing The target deposit is fractured, air is injected, the deposit is ignited to heat the formation, and resulting shale oil is moved through the natural or man-made fractures to production wells that transport it to the surface (Fig 62) However, difficulties in controlling the flame front and the flow of pyrolized oil can limit the ultimate oil recovery, leaving portions of the deposit unheated and portions of the pyrolized oil unrecovered

Thus, in situ processes avoid the need to mine the shale but require that heat be supplied underground and that product be recovered from a relatively nonporous bed As such, the in situ processes tend to operate slowly, behavior that the Shell in situ process (Fig 63) exploits by heating the resource to around 650 F (343 C) over a period of 3 to 4 years

CHAPTER SIX
The process involves use of ground-freezing technology to establish an underground barrier called freeze wall around the perimeter of the extraction zone The freeze wall is created by pumping refrigerated fluid through a series of wells drilled around the extraction zone The freeze wall prevents groundwater from entering the extraction zone, and keeps hydrocarbons and other products generated by the in situ retorting from leaving the project perimeter High yields of liquid products, with minimal secondary reactions, are anticipated (Mut, 2005; Karanikas et al, 2005) In situ processes avoid the spent shale disposal problems because the spent shale remains where it is created but, on the other hand, the spent shale will contain uncollected liquids that can leach into ground water, and vapors produced during retorting can potentially escape to the aquifer (Karanikas et al, 2005) Modified in situ processes attempt to improve performance by exposing more of the target deposit to the heat source and by improving the flow of gases and liquid fluids through the rock formation, and increasing the volumes and quality of the oil produced Modified in situ involves mining beneath the target oil shale deposit prior to heating It also requires drilling and fracturing the target deposit above the mined area to create void space of 20 to 25 percent This void space is needed to allow heated air, produced gases, and pyrolized shale oil to flow toward production wells The shale is heated by igniting the top of the target deposit Condensed shale oil that is pyrolized ahead of the flame is recovered from beneath the heated zone and pumped to the surface The Occidental vertical modified in situ process was developed specifically for the deep, thick shale beds of the Green River Formation About 20 percent of the shale in the retort area is mined; the balance is then carefully blasted using the mined out volume to permit expansion and uniform distribution of void space throughout the retort (Petzrick, 1995) In this process, some of the shale was removed from the ground and explosively shattered the remainder to form a packed bed reactor within the mountain Drifts (horizontal tunnels into the mountain) provided access to the top and bottom of the retort The top of the bed was heated with burners to initiate combustion and a slight vacuum pulled on from the bottom of the bed to draw air into the burning zone and withdraw gaseous products Heat from the combustion retorted the shale below, and the fire spread to the char left behind Key to success was formation of shattered shale of relatively uniform particle size in the retort, at reasonable cost for explosives If the oils shale contains a high proportion of dolomite (a mixture of calcium carbonate and magnesium carbonate; for example, Colorado oil shale) the limestone decomposes at the customary retorting temperatures to release large volumes of carbon dioxide This consumes energy and leads to the additional problem of sequestering the carbon dioxide to meet global climate change concerns
