The container has interior hinging baffles for dividing the container into compartments and preventing the contents in the container from moving around during transport. The container has a tailgate that is connected to the baffles such that pivoting the tailgate causes the baffles to pivot. The container also includes a sealable lid that can be opened for loading contents into the container and closed for preventing spillage of the contents during transportation. A cleaning system and heating system for the container are also described.
This application relates to an apparatus and method for cleaning drill cuttings recovered from a wellbore. Specifically, the apparatus includes an effective system for handling and washing drill cuttings at a well site to remove hydrocarbon contaminants. The system successively washes hydrocarbon contaminated drill cuttings in organic solvent and water to remove and recover the hydrocarbon contaminates, and produce cleaned drill cuttings that may enable disposal of clean drill cuttings without further treatment.

This application describes a method and apparatus for cleaning drill cuttings from a wellbore. Specifically, the apparatus includes an effective system for handling and washing drill cuttings in a modular system adapted for use at a well site. The system successively washes hydrocarbon contaminated drill cuttings in organic solvent and water to remove and recover the hydrocarbon contaminates enabling disposal of clean drill cuttings.
