“…The intermittent and variable nature of oil spill collection operations tend to discourage interest in such approaches, even if technically feasible. Some research, however, has been carried out in an analogous situation; research has shown that it is feasible to recover oil from waste drilling fluid (Zhu et al 2011b). In the cited study, oil recovery was found to be greatly enhanced by the use of a nonionic surfactant (demulsifier) with either calcium chloride or aluminum sulfate (coagulant), followed by nonionic or cationic acrylamide polymer (flocculant).…”

“…As indicated by the studies conducted thus far, the heavy metals contained in drill cuttings occur mainly in the form which is hardly available for living organisms, which is indicated by low percentage of their leaching (Mikos-Szymańska et al 2018; Cel et al 2017). In the studies by Zhu et al (2011) conducted on the drill cuttings containing the residues of oil-based drilling uid, the highest leachability -amounting to 1.61% -was observed in the case of copper, whereas for cadmium and lead it was lower, reaching 0.51% and 0.20%, respectively (Zhu et al 2011).…”

A greenhouse experiment was carried out to evaluate the influence of drill cuttings addition on the accumulation of heavy metals in soil, in plant biomass (Trifolium pretense L.) cultivated on soils with the addition of this type of waste. The transfer and transformation of heavy metals in the soil with drill cuttings– Trifolium pretense L were discussed.Drilling waste in the amount of 2.5%, 5%, 10% and 15% of dry weight were added to acidic soil. The concentrations of heavy metals in the soil and plant materials were determined by an inductively coupled plasma mass spectrometry method. Results indicated that drilling wastes addition had a positive influence on the growth of Trifolium pretense L. However, the concentrations of heavy metals increased in the prepared mixtures along with the dose of drilling wastes. The drilling wastes addition also changed the metal accumulation capacity in plant parts. Nevertheless, the concentrations of heavy metals in soils and above-ground parts of plants did not exceed the permissible values in respective legal standards. The values of the heavy metals bioconcentration coefficient in Trifolium pretense L at the highest dose of drill cuttings were as follows: in the above-ground parts Cd>Cu>Ni>Cr>Pb>Zn, in roots Cd>Ni>Cr>Zn>Pb>Cu.An artificial neural network model was developed in order to predict the concentration of heavy metals in the plants cultivated on the soils polluted with drill cuttings. The input (drill cuttings dose, pH, organic matter content) and the output data (concentration of heavy metals in the shoot cover) were simulated using an artificial neural network program. The results of this study indicate that an artificial neural network trained for experimental measurements can be successfully employed to rapidly predict the heavy metal content in clover. The artificial neural network achieved coefficients of correlation over 90%.

“…Oil-based drilling fluids have been widely used in oil and gas drilling because of its excellent properties of viscosity stability, heat-resistance, inhibition ability to shale and lubricating ability. The use of oil-based drilling fluids brings great convenience, but also produces oily drilling cuttings which belong to hazardous waste (Zhu et al 2011;Siddique et al 2017). Petroleum hydrocarbons in oily cuttings are the main components that are likely to seriously affect ecosystems such as soil and water on land (Siddique et al 2017).…”

Thermal desorption disposal of oily drilling cuttings was tested on the developed medium sized experimental system. The thermal desorption unit adopted electromagnetic induction heating during continuous conveying of materials by double screws, and the handling capability was 250 L/h. Thermal desorption test at different temperatures (300-550 °C) were carried out in conditions of residence times of 7 min and 12 min respectively. Total petroleum hydrocarbon (TPH) content of samples after treatment reduced to less than 1% when heating temperature up to 450 °C, and the oil removal rate was about 95%. The residual content of TPH dropped to 0.3% when heating temperature at 550 °C and residence time reached to 12 min. The temperature distribution of the material in heating bed obtained by numerical simulation based on test operating conditions. A temperature rising lag area of materials in filling section of barrel was found when heating. The material temperature in this area was only about 55-65% of the setting value when residence time reach to 12 min, while the other areas temperatures could up to above 90%, and the deviation between the material temperature and the setting value became obvious when the temperature is higher.
