The cuttings are treated in a treatment stage comprising a fluidized bed treater to reduce oil content of the cuttings to less than 1% by weight. The cuttings are provided to the treatment stage from a preparation stage that lowers oil content of the cuttings to a suitable range for the treatment stage and sizes the cuttings to a suitable dimension range for the treatment stage. ## Claims ### Claim 1 A method, comprising: reducing oil content of solids in a dryer; reducing a size of a portion of the solids in a sizer; and treating the solids in a fluidized bed treater in a treatment stage to reduce oil content of the solids to less than 1% by weight. ### Claim 2 A method, comprising: reducing oil content of solids in a dryer; using a separator to separate solids from oil recovered in the dryer; reducing a size of a portion of the solids in a sizer; routing solids recovered in the separator to the sizer; and routing solids from the sizer to a fluidized bed treater in a treatment stage to reduce oil content of the solids obtained from the sizer to less than 1% by weight. ### Claim 3 A method, comprising: reducing oil content of solids in a dryer to a target; using a separator to separate solids from oil recovered in the dryer; reducing a size of a portion of the solids in a sizer; routing solids recovered in the separator to the sizer; and routing solids from the sizer to a fluidized bed treater in a treatment stage to reduce oil content of the solids obtained from the sizer to less than 1% by weight, wherein the target is matched to a capacity of the fluidized bed treater. ### Claim 4 (depends on 1, 2, 3) The method of any of claims 1 to 3, wherein reducing the size of the portion of the solids comprises reducing a maximum dimension of the solids to 3.5 mm. ### Claim 5 (depends on 1, 2, 3, 4) The method of claims 1 to 4, further comprising collecting hydrocarbon separated from the solids and using the hydrocarbon to provide hot gas to the fluidized bed treater. ### Claim 6 (depends on 1, 2, 3, 4, 5) The method of any of claims 1 to 5, further comprising applying heating radiation to the solids in the fluidized bed treater. ### Claim 7 (depends on 1, 2, 3, 4, 5, 6) The method of any of claims 1 to 6, further comprising recycling hot gas of the treatment stage. ### Claim 8 (depends on 7) The method of claim 7, wherein recycling hot gas of the treatment stage comprises converting hydrocarbons in the recycled gas. ### Claim 9 (depends on 8) The method of claim 8, wherein treating the solids in the fluidized bed treater comprises heating a treatment gas using a hot gas source, and converting hydrocarbons in the recycled gas comprises combusting the hydrocarbons in the hot gas source. ### Claim 10 (depends on 9) The method of claim 9, wherein treating the solids in the fluidized bed treater comprises heating a treatment gas using a hot gas source, and converting hydrocarbons in the recycled gas comprises oxidizing the hydrocarbons in a converter. ### Claim 11 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) The method of any of claims 1 to 10, further comprising providing a catalytic layer within the fluidized bed treater and obtaining thermal energy by converting organic molecules using the catalytic layer. ### Claim 12 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 11) The method of any of claim 1 to 8 or 11, wherein treating the solids in the fluidized bed treater comprises heating a treatment gas in an electrical heater. ### Claim 13 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) The method of any of claims 1 to 12, further comprising recovering fines from an effluent of the fluidized bed treater and combining the recovered fines with solids exiting the fluidized bed treater. ### Claim 14 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13) The method of any of claims 1 to 13, further comprising recovering heat from the solids exiting the fluidized bed treater. ### Claim 15 (depends on 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14) The method of any of claims 1 to 14, further comprising condensing condensable materials in gas from the fluidized bed treater.
