Reuse of stabilized petroleum drilling wastes as sub-bases

Abstract

Most petroleum drilling wastes contain varying amounts of petroleum hydrocarbons, organic and inorganic chemicals and metals. The presence of these pollutants affects the physical and chemical process in soil and water after the release is completed. Petroleum drilling wastes are disposed of in open pits known as ''mud-pit'' These wastes are stabilized in the laboratory to find economical proportions of drilling waste, fly ash, Lime and cement. After laboratory investigations were completed, the field study was conducted as a joint effort by researchers at Anadolu University and Turkish Petroleum Corporation (TPAO). In this study, petroleum drilling wastes were stabilized with a pozzolanic lime, fly ash and cement. This stabilization produced chemically and physically stable and mechanically handable new products. These products were then used as sub-base material in the pilot field study. The parameters that are involved in such a determination are strength, permeability, durability, leachate, pH, oil and total metal content of stabilized mixtures.
