Salt Drilling Problems in North Dakota
… four major formations encountered in oil well drilling are the Prairie Evaporite of Devonian age, Mississippian Charles, Permian Opeche, and the Spearfish of Triassic age. A variety of drilling muds including gypsum, lime, high PH, barium carbonate, and saturated salt base muds have been used …

Development of an innovative and environmentally sustainable solid waste stream treatment process.
… from oil and gas exploration and d) Oil based drilling muds . The petroleum sludge wastes typically are water-in-oil emulsion that are stabilised by fine solids. The Hazardous Waste Directive classifies oily sludges and oil contaminated solids as hazardous waste due to its carcinogenic nature. …

The Environmental Sensitivity of Cold-water Corals Lophelia pertusa
… (NAA)), and to look for evidence of exposure to drilling muds and cuttings (discharges). In addition, live corals were exposed to 4-h sedimentation events of increasing rates and polyp behaviour analysed. Sediment removal mechanisms were also examined. Finally, skeletal characteristics and …

Physical characteristics and aquatic settlement properties of offshore drill-cuttings.
Drilling operations have been proven to cause pollution in the marine environment. From these environmental concerns, regulations and drilling muds evolved towards more environmental orientated operations. The environmental impact assessment is now compulsory and made public. In order to carry out …

Contaminant migration of oil-and-gas drilling fluids within the glaciated sediments of north-central North Dakota
… reclamation in North Dakota is to bury the drilling muds in shallow trenches near the borehole. These muds are saltwater based (between 100,000 and 300,000 mg/L of NaCl) and can contain high concentrations of chromium, lead, and other. toxic trace metals. </p><p>Two reclaimed oil and gas …

NMR response of liquids and of natural gas mixtures
This research relates T 1 and T 2 to thermodynamic and transport properties, such as composition and possibly density and viscosity, for types of reservoir fluids that have not previously been systematically studied using nuclear magnetic resonance (NMR). NMR measurements, which provide …

The effect of oil-and-gas well drilling fluids on shallow groundwater in western North Dakota
… of an oil-and-gas well in North Dakota the drilling fluid is buried in the reserve pit at the site. Reclamation of the drill site is expedited by digging a series of trenches which radiate out from the reserve pit, The majority of buried drilling fluid is ultimately contained within these …
