Fracking by the numbers: Experience after 10 years

In a single year, fracking wells across the country released at least 5.3 billion pounds of the potent greenhouse gas methane, as much global warming pollution as 22 coal-fired power plants. This statistic is one of many in a new study by Environment America Research & Policy Center that quantifies the environmental harm caused by …

Concurrence of aqueous and gas phase contamination of groundwater in the Wattenberg oil and gas field of northern Colorado

Concurrence of aqueous and gas phase contamination of groundwater in the Wattenberg oil and gas field of northern Colorado Li H, Son JH, Carlson KH. Abstract The potential impact of rapid development of unconventional oil and natural gas resources using hydraulic fracturing and horizontal drilling on regional groundwater quality has received significant attention. Major concerns …

Towards a Road Map for Mitigating the Rates and Occurrences of Long-Term Wellbore Leakage

Towards a Road Map for Mitigating the Rates and Occurrences of Long-Term Wellbore Leakage Key findings: “… the severity of the problem is not known because neither industry or oil and gas regulators are collecting the data.” Natural gas seeping from 500,000 wellbores represent “a threat to environment and public safety” due to groundwater contamination, …

Environmental Impacts of Fracking Related to Exploration and Exploitation of Unconventional Natural Gas Deposits (part 2)

This report issued by German authorities shows that exposure and health outcomes research related to unconventional oil and gas operations is urgently needed and that community engagement is essential in the design of such studies. Bibliography: Uwe Dannwolf, Anke Heckelsmüller (editors), Nikolaus Steiner and Carola Rink (Anwaltskanzlei Steiner), Dirk Weichgrebe, Katrin Kayser, Ralph Zwafink, Karl–Heinz …
