Microwave Drying of Drilled Cuttings in the Context of Waste Disposal and Drilling Fluid Recovery

Energy Technology, 2014
AbstractThe use of drilling fluids in oil drilling process generates solid–liquid mixtures that must be separated. One of the aims of this process is compliance with environmental laws regarding to disposal of waste from drilling activities. The present study aims to investigate the microwave drying of contaminated drilled cuttings.

Fluid Bed Catalytic Oxidation: An Underdeveloped Hazardous Waste Disposal Technology

Hazardous Waste, 1984
ABSTRACT Fluid bed incinerators have been used to dispose of a wide variety of hazardous wastes including refinery waste streams, surplus explosives, PCB-contaminated transformer oil and oxychlorination process wastes. Both inert and catalytic solids have been employed separately and in mixed beds or sequential reactors.

O and H diffusion in uraninite: Implications for fluid–uraninite interactions, nuclear waste disposal, and nuclear forensics

Geochimica et Cosmochimica Acta, 2011
Abstract Diffusion coefficients for oxygen and hydrogen were determined from a series of natural uraninite–H 2 O experiments between 50 and 700 °C. Under hydrous conditions there are two diffusion mechanisms: (1) an initial extremely fast-path diffusion mechanism that overprinted the oxygen isotopic composition of the entire crystals regardless of ...

Offshore Disposal of Oil-Based Drilling-Fluid Wastes An Environmentally Acceptable Solution

SPE Drilling & Completion, 1993
Summary Oily cuttings and waste fluid are byproducts of oil-based drilling muds. In such difficult drilling environments as the Gulf of Mexico, where oil-based fluids often are preferred, personnel safety, environmental, and economic concerns are exacerbated by the necessity to transport these cuttings and fluids to shore for disposal ...

Simulation of Fluid Flow and Energy Transport Processes Associated With High‐Level Radioactive Waste Disposal in Unsaturated Alluvium

Water Resources Research, 1986
Many parts of the Great Basin have thick zones of unsaturated alluvium which might be suitable for disposing of high‐level radioactive wastes. A mathematical model accounting for the coupled transport of energy, water (vapor and liquid), and dry air was used to analyze one‐dimensional, vertical transport above and below an areally extensive repository.

An examination of metal inputs to the southern Beaufort Sea by disposal of waste barite in drilling fluid

Ocean Management, 1982
Abstract Barites often contain trace metal impurities. Oil exploration in the Beaufort Sea will require barite as a major component of drilling fluid, most of which will be disposed after drilling. The trace metal impurities Hg, Pb, Zn and Cu have been examined by considering the natural budget and residence time of these elements for the Beaufort ...
