ABSTRACT:
The process for environmental pacification of drill cuttings which contain drilling fluid residue is characterized by mixing said cuttings with dehydrated limestone coke ash in the presence of water. Upon mixing the drilling fluid residue becomes entrapped into a non-leaching solid. Following treatment of drill cuttings with dehydrated limestone coke ash the resulting product has particular use as a road or work area base in connection with a topping which includes calcium sulfate hemihydrates.
