Only a handful of the thousands of waste disposal wells across the United States have been linked to induced or triggered earthquakes. Still, two well-documented cases—Rocky Mountain Arsenal, Colorado, in the 1960s (Healy et al. 1968) and Paradox Valley, Colorado, in the 1990s (Ake et al.

Abstract Secondary calcite residing in open cavities in the unsaturated zone of Yucca Mountain has long been interpreted as the result of downward infiltration of meteoric water through open fractures. In order to obtain information on the isotopic composition (δD and δ 18 O) of the mineral-forming water we studied fluid inclusions from this calcite.

SPE International Conference on Health, Safety, and Environment in Oil and Gas Exploration and Production, 1998
Abstract During the next decade and beyond, a large number of wells will be drilled in Eastern Venezuela in order to produce very heavy oil. Because of both the nature of the reservoir and the length of the horizontal section, water based drilling fluids will become contaminated with anywhere from 3–20% crude oil during the drilling ...

Hazardous Waste Disposal by Supercritical Fluids
Separation Science and Technology, 1997In the presence of water or carbon dioxide in the supercritical state, organic materials can be oxidized by oxygen practically completely within seconds. The report contains descriptions of test rigs and experimental findings. Additional R&D work is necessary for technical-scale application in cleaning organically polluted liquid effluents.

Subseabed disposal of radioactive waste: effects of consolidational fluid flow [PDF]
Environmental Geology, 1996 Subseabed disposal of radioactive waste applies a multiple-barrier concept with the sediment being the most important barrier for preventing a release of nuclides into the biosphere. While many investigations have been carried out to analyze the risk potential in this type of disposal, the effects of sediment consolidation and associated fluid flow ...

Advances in E-Waste Recycling: Physical and Chemical Treatment Methods
Highlights in Science Engineering and Technology, 2023The unprecedented rise in production and consumption of electronic devices has resulted in staggering amounts of electronic waste (e-waste). Improper recycling and disposal of e-waste can cause severe environmental and public health repercussions due to ...

Durability of Zirconolite in Hydrothermal Fluids: Implications for Nuclear Waste Disposal
MRS Proceedings, 2000ABSTRACTSynthetic zirconolite (CaZrTi2O7) doped with rare earth elements (REEs) and Hf has been subjected to corrosion tests in a closed system at elevated temperature and pressure in fluids with various compositions. Together with previous studies, the results indicate only a very weak corrosion below 250°C at a pressure of 50 MPa.

The Use of Biotreatment Technology to Dispose of Offshore Drilling Waste Oily Fluids
Advanced Materials Research, 2012Disposing of oil-based drilling fluid with biotreatment technology has many advantages: it is only 30-50% of the expense of conventional chemical or physical processing technologies, has a low impact on the environment, with no secondary pollution, and utilizes local control and entails simple operations.
