Characterization of drilling waste from shale gas exploration in Central and Eastern Poland.

摘要: The purpose of this research was to determine and evaluate the chemical properties drilling waste from five well sites in Central Eastern Poland. It found that spent fluids can contain high values nickel mercury (270 8.77 mg kg−1, respectively) exceed maximum permissible limits recommended by EC regulations for safety soils (75 mg kg−1 1.5 mg kg−1 mercury). heavy metal concentrations studied drill cuttings did not regulation. Drilling wastes macroelements (e.g., calcium, magnesium, potassium) as trace elements copper, iron, zinc, manganese) are essential plant growth. stated water extracts cuttings, according anions presence, had any specific constituents concern based on FAO irrigation guidelines, USEPA WQC, toxicity values. X-ray diffraction analysis used understand structure texture fluid solids cuttings. Analysis mineralogical character revealed they contained calcite, quartz, muscovite, sylvite, barite, dolomite, orthoclase. Drill calcite barium chloride.
