Groundwater methane in relation to oil and gas development and shallow coal seams in the Denver-Julesburg Basin of Colorado

Example of a wellbore failure (Graphic: Sherwood et al., PNAS 2016)

Abstract: Unconventional oil and gas development has generated intense public concerns about potential impacts to groundwater quality. Specific pathways of contamination have been identified; however, overall rates of contamination remain ambiguous. We used an archive of geochemical data collected from 1988 to 2014 to determine the sources and occurrence of groundwater methane in the Denver-Julesburg …

Methane contamination of drinking water accompanying gas-well drilling and hydraulic fracturing

There is systematic evidence for methane contamination of drinking water associated with shale gas extraction in the aquifers above the Marcellus and Utica shale formations in the U.S. Northeast. Regulation is needed to ensure the sustainable future of shale-gas extraction and to improve public confidence in its use. Bibliography: Stephen G. Osborn, Avner Vengosh, Nathaniel …

Coalbed Methane: Clean Energy for the World

This article sheds a light on the special geology and production requirements of coal bed methane (CBM). It describes some challenges of drilling and cementing in CBM plays, but unfortunately the authors waste no thought on risks of CBM production like groundwater contamination or massive methane leakage which further damages the climate. From the article …
