A method and apparatus for drilling a wellbore in the earth from a location in a body of water wherein the drilling operation generates a substantial amount of a mixture of solid drilling cuttings, water, and at least one hydrocarbonaceous oil, wherein the water and oil are removed from the solid drilling cuttings so that the cuttings are put into a condition in which they can be disposed of in the body of water or elsewhere without adverse effects.
