Common drilling procedures for oil and gas, used widely around the world, produce a consistently increasing amount drill cuttings containing oil. In some cases, drill cuttings even contain other hazardous components such as mercury or NORM (Natural occurring Radioactive Material), requiring special attention. Treatment of drill cuttings is therefore beneficial from both an environmental and an economic standpoint, allowing valuable drilling oil to be recovered, and ensuring environmentally sound disposal of the drill cuttings. Our VacuDry® technology is designed to safely separate oil, water and mercury from the solids (including NORM), allowing reuse of the oil and safe disposal of the water, mercury, solids and NORM.


Benefits of VacuDry® drill cuttings plants

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)
