Drilling for oil and gas produces a constantly increasing amount of oil containing drill cuttings worldwide. In some cases, drill cuttings even contain other hazardous components like mercury or NORM (Natural occurring Radioactive Material) that require special attention. Therefore, the treatment of drill cuttings is required for both the recovery of valuable drilling oil, as a major economical factor, and assuring environmentally sound disposal of the drill cuttings. VacuDry® is the only drill cuttings treatment process where drilling fluid is recovered in highest quality. The drilling fluid fulfils the requirement for drilling operations and therefore can be reused or sold to the drilling industry. By this, one can turn waste into a valuable resource – reducing waste, minimizing environmental impact, and boosting the business model. This reduces reliance’s on fossil fuel, oil imports, disposal costs and landfills.
Our VacuDry® technology ensures both by safely separating oil, water and mercury from the solids, allowing reuse of the oil, and safe disposal of water, mercury and solids.

Drilling fluid
VacuDry® is the only drill cuttings treatment process where drilling fluid can be recovered in its highest-quality form. The recovered fluid fulfils the requirement for standard drilling-operations and therefore can be reused, or resold to the drilling industry.
The quality is able to remain stable during the VacuDry® process due to:
- Vacuum (below 100 mbar(abs))
- Absence of oxygen (nitrogen blanketing)
- Low temperatures (less than 200 °C)
