Numerical Model of Fluid Flow through Heterogeneous Rock for High Level Radioactive Waste Disposal
AIP Conference Proceedings, 2007An international consensus has emerged that deep geological disposal on land is one of the most appropriate means for high level radioactive wastes (HLW). The fluid transport is slow and radioactive elements are dangerous, so it's impossible to experiment over thousands of years. Instead, numerical model in such natural barrier as fractured underground

Recycling and Final Disposal of Waste Generated While Mixing Drilling and Completion Fluids
Proceedings of Latin American & Caribbean Petroleum Engineering Conference, 2007Abstract As the emphasis on safety and efficiency increases in the oil industry, there has been a corresponding improvement in the quality of packaging for chemical products. Examples of higher standards include plastic shrink-wrap covers, better-designed pallets, and fewer sacks loaded per pallet.

Useful Recycling and Safe Disposal Technology of Waste Oil Based Drilling Fluids and Its Application
International Petroleum Technology Conference, 2013Abstract Waste oil-based drilling fluids are hazardous wastes containing oil, heavy-metal and organic pollutants. However, the common treatment methods at home and abroad these methods not only waste many useful resources (because the oil is discarded rather than recovered) but also increase the pro-environment cost
