  • Patent number: 11066881
    Abstract: A method and composition for stabilizing drill cuttings commences by providing precipitated calcium carbonate (PCC). The PCC is dried to a moisture level of about 10% or less. Drying by heat not to exceed 400° F. is preferred to prevent changes in the PCC. The dried PCC is blended with kiln dust to compose a generally uniform admixture. In the admixture, the kiln dust is not to exceed 40%. The admixture is introduced to the drill cuttings to initiate a nucleation reaction within the commixture of drill cuttings and the admixture.
    Type: Grant
