Petroleum related wells in Montana, North Dakota, and South Dakota

The the Williston Basin has been a leading petroleum producer for over a half century with development beginning around the turn of the 20th century. The spatial and temporal spread of the associated wells is important from both an economic perspective but also a natural resource view. These data were gathered from the state/province oil and gas divisions for use by USGS researchers and their collaborators in water resource specific studies. Each state/province provides slightly different information for each well, with some providing more information and others less. We attempted to create a spatial cross-walk that allowed each database to be merged to one another to create a final regional spatial database. Each...

Strontium isotope detection of brine contamination in the East Poplar Oil Field, Montana

Brine contamination of groundwater in the East Poplar oil field was first documented in the mid-1980s by the U.S. Geological Survey by using hydrochemistry, with an emphasis on chloride (Cl) and total dissolved solids concentrations. Supply wells for the City of Poplar are located downgradient from the oil field, are completed in the same shallow aquifers that are documented as contaminated, and therefore are potentially at risk of being contaminated. In cooperation with the Office of Environmental Protection of the Fort Peck Tribes, groundwater samples were collected in 2009 and 2010 from supply wells, monitor wells, and the Poplar River for analyses of major and trace elements, including strontium (Sr) concentrations...
