• Following the pressure test, a temperature log will be run on the cemented portion of the <br />well to identify any deficiencies. <br />9. DESCRIPTION OF INJECTATE <br />The AMSO process involves injecting or recycling fuel oil and produced shale oil into <br />the heater section of the heater-producer well. <br />The fuel oil will be a standard #1 or #2 commercial product. About 70 barrels of fuel oil <br />will be used initially to start the surface facilities and to provide an oil pool for the <br />downhole heater. In addition to initiating the Pilot Test, fuel oil may also be used to <br />replenish the boiling pool of oil during the Pilot Test. A Material Safety Data Sheet for <br />fuel oil is included as Attachment 1. <br />The produced shale oil or a lighter distillation cut may be recycled from the surface to the <br />retort to maintain the boiling oil pool. The produced shale oil product is estimated to <br />have a specific gravity of about 0.84, a boiling range from approximately 40 °C to 500 <br />°C, and about 0.6 wt% organic sulfur, 0.7 wt% organic nitrogen, and <IOppm arsenic. <br />The distillation cut is expected to have a specific gravity of about 0.82, a boiling range <br />from approximately 40 °C to 400 °C, and somewhat less sulfur, nitrogen, and arsenic <br />content. <br />• <br />10. CHEMICAL ANALYSIS OF INJECTATE <br />Please see number 9 above. <br />11. EFFECT ON GROUNDWATER <br />Neither fuel oil nor shale oil described above will meet current drinking water standards. <br />Exceedances of current drinking water standards in USDWs are not anticipated as <br />AMSO's heater-producer well and retort are isolated from all USDWs. <br />Contamination of USDWs due to retorting will not occur. The Pilot Test will retort a <br />limited volume of oil shale surrounding the well bore within the RI zone. The retorted <br />volume will exhibit an increase in porosity and some loss of mechanical strength due to <br />the extraction of kerogen. Increased porosity can be expected to alter the hydraulic <br />properties of the rock mass within the immediate vicinity of the well bore. <br />A reasonable potential exists that the void will remain stable. However, some caving and <br />fracturing may occur above the retort until the resulting rubble can support the <br />overburden. Our plan is to prevent any caving or fracturing from altering the hydrologic <br />propertries of the nahcolitic oil shale above about 1900-ft, precluding the potential for <br />contamination of aquifers located hundreds of feet above the RI Pilot Retort zone. <br />C? <br />22
