Abstract
The apparatus and method provide for the removal of well fluids from well cuttings and a method of disposal thereof. A vibratory separator mechanically shakes the well fluids from the cuttings into a first compartment and the well cuttings fall into a second compartment. Once the well cuttings are dried, cement kiln dust (CKD) is added to neutralize any remaining well fluids on the well cuttings. The neutralized well cuttings are applied to the roadbed of a gravel or dirt road.
