Drill cuttings waste, Microwave treatment, oil Contamination, Oil-based mud treatment


Drilling waste is a vital and persistent problem found in the petroleum industry which is mainly related to drilling and oil production. When drilling fluids ruminants are discharged on the ground, human health is affected by the toxic of oil contamination and the chemicals of liquid fraction ruin organisms functional and contaminate the groundwater as a result of seeping. A microwave technique was used to treat the remain drill cuttings resulting from drilling fluid. Whereas amounts of drill cuttings were taken from the southern Rumaila oilfields, prepared for testing and fixed with 100 gm per sample and contaminated with two types of crude oil, one from the southern Rumaila oilfields with Specific gravity of 0.882 and the other crude oil from the eastern Baghdad oilfield of Specific gravity 0.924. The concentrations of 7.5%, 10%, 12.5% ​​and 15% w/w in mass was chosen to be the pollution percentage. Samples were treated in the microwave with different power applied of 180, 540, and 900 watt and a time period of 50 minutes is divided into 5 parts for analysis 0, 10, 20, 30 and 50 min. the purpose of this study was trying to reach the zero-discharge concept treatment or near. It was found that the results of 22 sample reached below 1% w/w in mass, except for two samples of 180-watt power applied and oil contamination of 15% w/w in mass they reached about 1.5-1% w/w in mass. The results show a great declination in oil contamination even with highest pollution with lower power applied.
