Effects of Coalbed Methane Production on Stream Flow

Coalbed methane production has the potential to reduce instream flows in Powder River Basin streams. Quantifying this effect is difficult, but important, for water users in both Wyoming and Montana. Isotope tracing of coal aquifer groundwater entering the streams can help.

Effects of Enhanced Oil Recovery on Production Engineers, Elm Coulee Field, Bakken Reservoir, Richland County, Montana

This presentation describes research at Montana Tech to improve oil recovery rates in the Elm Coulee Oil Field in the Bakken Reservoir, Richmond County, Montana. The slides display current recovery rate predictions, enhanced oil recovery methods, reservoir model building and history matching strategies. Recommended development strategies include implementing hydrocarbon gas injection operations to improve current oil recovery rates by more than 75%. The impact of increased production on Production Engineers is also described. The Principal Investigators include John Evans, Leo Heath, David Reichhardt and Burt Todd in the Petroleum Engineering Department.

Water Quality Issues in the Williston Basin, Montana and North Dakota

The Williston basin has been producing oil and gas since the 1950s, but production has increased recently due to use of hydraulic fracturing and horizontal drilling technologies to extract oil and gas from the Bakken and Three Forks Formations. As concern about effects of energy production on surface-water and groundwater quality increases, the characterization of current water-quality conditions is highly important to the scientific community, resource managers, industry, and general public.
