Opis:
Drilling waste constitutes industrial waste produced during mining activities involving drilling holes for exploration and exploitation. In Poland, the growing interest in shale gas, and the necessity of extracting it from significant depths led to the production of approximately 80 thousand tons of drilling waste (in 2013). Only a small part of this waste is utilized in the production of construction materials. Over 80% of produced waste is deposited either at the drilling site or on landfills. Therefore, it is important to assess the environmental risk connected with utilization of this type of waste. Drilling waste from shale gas mining contains various kinds of toxic heavy metals, which may be released into the environment by leaching. The paper describes the performed studies and presented the results of leachability, i.e. potential heavy metal mobility, from two types of drilling waste produced through the use of water- and oil-based drilling muds. Standard 24-hour extraction test was performed in water with solid to liquid phase ratio of 1 kg: 10 dm3. It was proven that the susceptibility of heavy metals to leaching from drill cuttings with water-based mud decreases in the order Ba > Zn > Pb > Cu > Ni > Cr, while in the case of drill cuttings with oil-based mud, it changes in the order Ba > Zn > Cr > Ni > Pb > Cu.

Opis:
Poland, due to the estimated shale gas deposits amounting to 346–768 billion m3 has become one of the most attractive regions for shale gas exploration in Europe. Throughout the period 2010–2015, 72 exploratory drillings were made (as of 4.01.2016), while hydraulic fracturing was carried out 25 times. Employing new drilling and shale gas prospecting technologies raises a question pertaining to their impact on the environment. The number of chemical compounds used (approximately 2000) for the production of new technological fluids may potentially pollute the environment. The fact that the composition of these fluids remains undisclosed hinders the assessment of their impact on the environment and devising optimal methods for managing this type of waste. The presented work indicates the chemical compounds which may infiltrate to groundwater, identified on the basis of technological fluids characteristics, as well as the review of studies pertaining to their impact on potable water carried out in the United States. The study focused on marking heavy metals, calcium, sodium, magnesium, potassium, chlorides and sulphates in the surface waters collected in proximity of Lewino well.
