RADIOACTIVE WASTE DISPOSAL BY HYDRAULIC FRACTURING.

摘要: The petroleum industry has developed, largely since World War II, the technique of hydraulic fracturing to increase oil recovery that is today almost universally used in reservoir rocks low permeability. Single injections 100,000 gal containing 250,000 lb sand are not unusual. Much same equipment and procedure may be for waste disposal, although there certain significant differences. disposal well at Oak Ridge was drilled cased a depth 1,000 ft shale by using standard oil-field method. casing slotted near bottom, self-hardening mixture paste, Portland cement, clay pumped down under high pressure form widespread, thin horizontal fracture which sets up solid. After 4 into slot, totaling roughly 500,000 gal, bottom plugged new slot cut some 10 higher well. (Abstract only - original available)
