Method for re-cycling wellbore cuttings

A method for remediating wellbore cuttings on an offshore rig, the method comprising

• transporting a system for remediating the cuttings to the offshore rig in transportable containers wherein each container weighs 20,000 pounds or less, the system including a thermal treatment system and a condensing system,
• stacking the transportable containers on the offshore rig so they occupy an area 10'.times.25' or less,
• feeding a slurry of the cuttings with oil, fine particulates, volatilizable contaminants and water to the thermal treatment system and heating the cuttings therein producing heated cuttings and volatilized oil and water,
• discharging the heated cuttings from the thermal treatment system,
• feeding the volatilized oil and water to a filter system, and
• filtering out fine particulates from the oil and water
• feeding the volatilized oil and water from the filter system 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.
