Abstract

A method for remediating cuttings from a wellbore has been invented which, in certain aspects, includes transporting a system for remediating the cuttings to an offshore rig in transportable containers, the system including a thermal treatment system and a condensing system; feeding a slurry of the cuttings with oil and water to the thermal treatment system and heating the cuttings therein producing heated cuttings an a stream with oil and water; discharging the heated cuttings from the thermal treatment; feeding the stream with oil and water to a condenser system producing a liquid stream; and feeding the liquid stream to an oil/water separator producing an oil stream and a water stream. In another method for remediating cuttings according to the present invention, the method includes feeding a slurry of the cuttings with oil, fine particulates, and water to a thermal treatment system and heating the cuttings therein producing heated cuttings and a stream with oil and water, discharging the heated cuttings from the thermal treatment, feeding the stream with oil and water to the filter system, filtering out fine particulates from the stream with oil and water, feeding the stream with oil and water to a condenser system producing a liquid stream, and feeding the liquid stream to an oil/water separator producing an oil stream and a water stream.
