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, …

Evaluating a groundwater supply contamination incident attributed to Marcellus Shale gas development

New techniques of high-volume hydraulic fracturing (HVHF) are now used to unlock oil and gas from rocks with very low permeability. Some members of the public protest against HVHF due to fears that associated compounds could migrate into aquifers. We report a case where natural gas and other contaminants migrated laterally through kilometers of rock …

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 …

Independent panel review of the Canadian natural Primrose flow to surface causation report

In 2013, there have been four Flow to Surface (FTS) events at Canadian Natural’s Cyclic Steam Stimulation (CSS) operation at Primrose. The bitumen seeped into a lake, muskeg and the forest for more than a year, killing wildlife and polluting the landscape. As it turned out, industry-induced fractures penetrated “generally impermeable shales” and passed through …

CO2, Methane, and Brine Leakage Through Subsurface Pathways: Exploring Modeling, Measurement, and Policy Options

Subsurface pathways, such as abandoned oil and gas wells and faults, can serve as leakage pathways for CO2 , methane, brine, and other fluids. These pathways allow fluids from deep subsurface formations to migrate into shallow groundwater aquifers or to the atmosphere. Between 200,000 and 970,000 abandoned wells in the state of Pennsylvania likely account …

An evaluation of water quality in private drinking water wells near natural gas extraction sites in the Barnett Shale Formation

An evaluation of water quality in private drinking water wells near natural gas extraction sites in the Barnett Shale Formation Author(s): Brian E. Fontenot (UT Arlington) Date: 07.2013 Source / Publisher: Environmental Science & Technology Key findings: The study found arsenic levels in groundwater within 3 km of gas installations at levels nearly 18 times …
