Drilling waste includes drilled rock or drill cuttings, spent drilling fluids, and drilling wastewater. Drilling also produces other wastes, but their volumes are relatively small. All three of these components of drilling waste contain water, particles of drilled rock, drilling mud components and sometimes oil (or other hydrocarbons) in varying proportions, which may be included in the waste when passing through oil-bearing formations or added as a lubricant to the drilling mud. The composition of drilling waste mainly depends on the geological section (rocks), type of drilling fluids and chemicals used to treat the drilling fluids.
In Ukraine, there are two methods of drilling oil and gas wells: pit and pitless. With pit drilling, drilling waste is collected, stored, neutralised, solidified and disposed of in waterproofed sludge pits directly at the drilling site. In the case of pitless drilling, drilling waste is accumulated in containers and metal tanks and transported to other locations (pits, storage facilities, landfills) for treatment or disposal.
