Introduction to a New Apparatus for Hydraulic Fracturing Tests
A new apparatus for hydraulic fracturing tests, on which the seepage and force boundary conditions can be controlled strictly, is briefly introduced here. Some test results obtained by using this apparatus are presented as an example. These results were compared with theoretical results obtained from rigorous mechanical analysis to illustrate the advantage of this ...

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 ...

Hydraulic fracturing facts presented by Chesapeake energy- points to biolargo opportunity
About Hydraulic Fracturing Hydraulic fracturing, commonly referred to as fracing, is a proven technological advancement which allows natural gas producers to safely recover natural gas from deep shale formations. This discovery has the potential to not only dramatically reduce our reliance on foreign fuel imports, but also to significantly reduce our national carbon dioxide (CO2) emissions and ...

CRS report on hydraulic fracturing and NEPA
Abstract This CRS report was prepared for members and committees of Congress. The National Environmental Policy Act (NEPA) requires federal agencies to consider the potential environmental consequences of the actions they propose to take by preparing one of three NEPA documents. Actions that fit within a categorical exclusion (CE) undergo a relatively low level of review because these are actions ...

Shale gas - Information on hydraulic fracturing (`fracking`)
Shale gas is natural gas – mainly methane – trapped within the micropores of shale formations or adsorbed onto the shale (sedimentary rock). In Europe, known deposits exist in the UK, France, the Netherlands, Germany, Poland, the Baltic States and Scandinavia. In Switzerland, deposits are suspected to lie in the Permo-Carboniferous trough of Northeastern Switzerland, below Lake ...

US EPA announces nationwide plans to study fracking impacts
Department’s state presence could influence future federal & state regulation As a follow-up from Enhesa’s June 2011 Flash coverage on recent U.S. concerns over hydraulic fracturing (“fracking”), Enhesa would like to share additional developments on this issue that heighten the probability of more stringent federal and state regulation. Ongoing concerns raised by ...

Cracking down on Fracking: The US Regulatory Trend and what that means for Oil Companies
In June 2011 Enhesa is focusing on an emerging Oil & Gas issue, which has recently become a major concern for Oil Companies in the United States. Hydraulic fracturing or “fracking” has long been used for natural gas and oil production in the United States. However, due to growing concern on its environmental impacts, the US Federal Government and various states are assessing the ...

The Stats on Fracking: The Real Numbers of Hydraulic Fracturing
Hydraulic fracturing, sometimes referred to as “fracking,” is among the largest and most influential trends in the global energy sector today. By injecting highly pressurized fluid into underground formations containing oil and natural gas, hydraulic fracturing makes it possible to exploit fossil fuel reserves that were previously too expensive or too difficult to reach with more ...

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, ...

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 ...

2015 Water and Hydraulic Fracturing Report
Over the past decade, the combination of horizontal drilling techniques and multi-stage hydraulic fracturing has led to a technological revolution in oil and gas development. It has given rise to a huge North American expansion of oil and gas development from unconventional (tight) resources. This rapid expansion has spurred evolution in industry practice, requiring a parallel development, or ...

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 ...

Treatment of hydraulic fracturing wastewater by wet air oxidation
Wastewater produced by hydraulic fracturing for oil and gas production is characterized by high salinity and high chemical oxygen demand (COD). We applied a combination of flocculation and wet air oxidation technology to optimize the reduction of COD in the treatment of hydraulic fracturing wastewater. The experiments used different values of flocculant, coagulant, and oxidizing agent added ...

Environmental solutions for the natural gas industries
As domestic natural gas production continues to grow, the industry faces unique air pollution control challenges that require custom-designed solutions. This White Paper examines two aspects of the natural gas exploration and production industry: Production of “frac sand” used in hydraulic fracturing and operation of dehydration units. America‟s natural gas industry continues ...

A review of non–renewable energy options in Illinois
The State of Illinois has the largest non–renewable (fossil) energy reserves among all the states in the USA. We report our studies on coal, oil and gas energy resources, conversions, consumptions and carbon dioxide sequestration advances in Illinois from the point of view of sustainability in energy and environmental. This includes reserves and characteristics of coal, oil and gas in the ...

Pumps that thrive under pressure
The Evolution of Hydraulic Transmission Technology in the Pressure Pumping Market. Fracking technology is driving transformation of North American energy production capabilities. Since 2005, most of the increase in domestic natural gas production resulted from ongoing development of horizontal drilling and hydraulic fracturing technology. Producers developed more efficient ways to extract gas ...

Hydraulic Fracturing and the Environment Whitepaper - Analytical and Measuring Instruments
The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...

Global Shale Gas Development: Water Availability & Business Risks
This report analyzes water availability across all potentially commercial shale resources worldwide.It also reveals that water availability could limit shale resource development on every continent except Antarctica. Shale resources are unevenly distributed worldwide and, for the most part, not located where freshwater is abundant. For example, China, Mexico, and South Africa have some of the ...
