Abstract
A method of treating drill cuttings containing a detectable amount of hydrocarbon-based drilling fluid comprises injecting a non-toxic additive to the cuttings and mixing the cuttings and additive to the point where the amount of hydrocarbon-based drilling fluid is less than 1% by weight. The method of treating cuttings includes the additional step of taking the mixture of cuttings and additive and disposing of the mixture directly to the soil, preferably in the immediate vicinity of the well site. A system is provided for carrying out the method, including structure for adding a quantity of an chemical additive to cuttings carrying a quantity of drilling fluid. The system further provides a controller to determine the cuttings load within the system, and controls to vary the quantity of treatment chemicals added to the cuttings according to the cuttings load.
