Can disclosure rules clarify what’s in our groundwater? Enhesa’s US consultant Rachel Degenhardt on hydraulic fracturing & groundwater contamination in ELQ
This month, Enhesa US Regulatory Consultant, Rachel Degenhardt, was published on the issue of hydraulic fracturing and groundwater contamination in Berkeley’s Ecology Law Currents, an online publication of Ecology Law Quarterly, one of the nation’s most respected and widely read environmental law journals. “The U.S. EPA is working to increase transparency regarding the ...

Effect of shear rate on the activity of enzymes used in hydraulic fracture cleanup of tight unconventional reservoirs
Injection of polymeric solutions in order to propagate a fracture and carry proppants to keep the fracture open is a common practice in hydraulic fracturing of ultra–tight formations. Polymeric fluids open and extend the already existing network of fractures. Considering the low permeability of the formation, small width of the micro–fractures, and the importance of fracture cleanup during the ...

New York governor pauses `fracking`
New York Gov. David Paterson has signed an executive order halting the controversial natural gas drilling process called hydraulic fracturing until July 1. The process --- also known as "fracking" -- has come under scrutiny because of its alleged harmful effects on underground drinking water and the environment -- although industry leaders have insisted it's safe. The governor's order -- which ...

EPA Considering Rule to Require Reporting Of Chemicals Used in Hydraulic Fracturing
The Environmental Protection Agency is considering a rulemaking that might require chemical manufacturers and processors, as well as oil and gas exploration companies, to report on chemicals used in hydraulic fracturing. In an advance notice of proposed rulemaking, the EPA said it is seeking information from industries, state agencies and others on the range of data the agency should obtain ...

Optimizing Water Management in Hydraulic Fracturing for Shale Oil and Gas Production
Centralized treatment of wastewater is emerging as a viable solution for long-term efficiency in managing water sourcing and wastewater treatment in hydraulic fracturing. The number of hydraulic fracturing (fracking) shale oil and gas wells in the United States continues to increase. Within the Bakken Shale formation alone, in North Dakota and Montana, upwards of 15,000 hydraulic fracturing ...

Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

Systematic approach to numerical simulation and modelling of shale gas reservoirs
With the rapid development of unconventional resources in the USA and its contribution by diminishing energy dependency on foreign supplies, reservoir simulation technology is facing new challenges in providing key information to be utilised for long-term development decisions. Therefore, growth in shale gas reservoir development necessitated new approach to reservoir simulation. In this paper, ...
