As part of a multidisciplinary investigation designed to assess the implications of coal-bed methane development on water resources for the Powder River Basin of southeastern Montana, six wells were drilled through Paleocene-age coal beds along a 31-km east–west transect within the Tongue River drainage basin. Analysis of geophysical logs obtained in these wells provides insight into the hydrostratigraphic characteristics of the coal and interbedded siliciclastic rocks and their possible interaction with the local stress field. Natural gamma and electrical resistivity logs were effective in distinguishing individual coal beds. Full-waveform sonic logs were used to determine elastic properties of the coal and an...

These ArcView shapefiles contain representations of the Hanna 77, 78, 79 and 81 coal drill hole locations. These shapefiles were created specifically for the National Coal Resource Assessment of the Northern Rocky Mountain and Great Plains Fort Union Coal Resources Area, and can be viewed in relation to other relevant themes in this area.

This dataset is field boundary polygons of Coalbed Methane (CBM) based on producing wells in the USA. Field outline polygons were created by buffering wells from each field. Buffered well polygons from each field were then unioned into a single polygon record (may contain multiple rings). A smoothing algorithm was applied to the polygons. Features are colored by Basin. Fields are coded with Geologic Ages, Formations, and Coal Names. Age Codes are Exxon Mobil Age Codes.
