Offshore Drilling & Production Waste Treatment

Turning Waste
into Value

Provides the next generation of compact and easy to operate integrated mechanical separation equipment in combination with environmentally friendly chemicals and skilled operations personnel to serve the offshore industry in managing slop water, drilling mud and drill cuttings.

Key features

  • Value creation by changing and improving from traditional inefficient treatment technologies, equipment and chemicals including methods.
  • Compact treatment unit and environmentally friendly chemicals for the treatment and re-use of fracking wastewater, completion fluids, produced water and any other industrial wastewater.
  • Environmentally friendly chemicals to destabilise the drilling fluids, oil-based mud (OBM) and water-based mud (WBM) allowing for the gravitational separation of the three different main elements water/brine, oil and solids.
  • Chemical solutions to treat completion fluids onsite for re-use.
  • Treatment offsite and onsite and disposal of polluted wastewater.

The production and disposal of oily sludges are considered as one of the most critical environmental issues in the petroleum industry, particularly in the petroleum producer countries. Annually, large quantities of oily sludges (more than 60 million tons) are generated and more than 1 billion tons of oily sludge has been accumulated worldwide.

 

Oily sludge in refineries

In particular, the sludge generated during the petroleum refining process has received increasing attention in recent years. It has been estimated that one ton of oily sludge is generated for every 500 tons of crude oil processed. Oily sludge is a complex and variable hazardous waste depending on the quality of crude oil as well as the processes used for water-oil separation. In general, oily sludge is composed of 40-52% alkanes, 28-31% aromatics, 8-10% asphaltenes, and 7-22.4% resins by mass. In addition, the oily sludge contains the heavy metals such as Zn, Cd, Pb, Cr, Cu, Ni and V.

 

Because of variations in the chemical composition of oily sludges, its physical properties such as density, viscosity, and heat value can vary significantly. Based on the integrated waste management strategy, three approaches including source reduction, oil recovery and disposal using different technologies such as thermal processes and biodegradation have been reported for oily sludge treatment.

 

 

Economical and good news for the environment

The development of environmentally friendly and economical technology for oily sludge management and treatment has for years been on the agenda of being a necessary achievement of sustainable development in the petroleum industry.

Enhanced Oil Recovery with Mud Split from Norwegian Technology

The oily sludge treatment with the Norwegian Technology solution allows for the separation and recovery for reuse of the different components of the sludge, namely oil, water and solids. The process takes place at ambient and heated temperature with the use of proprietary chemicals.”Oily sludge is a complex emulsion of various petroleum hydrocarbons (PHCs), water, heavy metals, and solid particles. Due to its hazardous nature and increased generation quantities around the world, the effective treatment of oily sludge has attracted widespread attention. Many methods deal with PHCs in oily sludge either through oil recovery or sludge disposal.
