ABSTRACT:
Waste drilling mud is stabilized for earthern burial. The waste drilling mud may be treated by flocculating, aggregating, agglomerating and dewatering the waste drilling mud and separating out free water. The free water may be reused or disposed of in a disposal well. The thickened, dewatered drilling mud solids may be further treated with a water absorbing binder to produce a residue which has sufficient bearing strength to support an earthen overburden and may be disposed of by burial. Suitable flocculating, agglomerating and dewatering polyelectrolytes may be used, including polyacrylamides, quarternary amine polymers and mixtures thereof. The water absorbing binders may include inorganic and organic materials, such as natural and synthetic water absorbing gums, polymers and inorganic colloidal absorbers.
