  • 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 ...

  • 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 ...

  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • 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 to ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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) ...

  • Case study - Groundwater monitoring around hydraulic fracturing sites in Colorado

    Hydraulic fracturing or ‘Fracking’ has become more prevalent and controversial in the US in recent years. More than 90 percent of new wells in the US are completed using this method. While it is endorsed by some as a game-changer that promises an increase in the nation’s economy due to energy independence, job creation, and lower energy prices; others are calling for a temporary ...

  • Pressure behaviours and flow regimes of a horizontal well with multiple inclined hydraulic fractures

    Hydraulic fractures have become a common stimulation application in the oil and gas industry, especially in tight formations. Published models assume the hydraulic fractures are vertical and symmetric. However, recent studies have shown that fractures are asymmetric and inclined with respect to the vertical direction and the axis of the wellbore. This paper introduces new analytical models that ...

  • Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources

    Natural gas plays a key role in our nation’s clean energy future. The United States has vast reserves of natural gas that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies, which enable greater access to gas in rock formations deep underground. ...

  • 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 ...

  • In Situ Remediation Technology Status Report: Hydraulic & Pneumatic Fracturing

    The purpose of this document is to describe recent field demonstrations, commercial applications, and research on technologies that either treat soil and ground water in place or increase the solubility and mobility of contaminants to improve their removal by pump-and-treat remediation. It is hoped that this information will allow more regular consideration of new, less costly, and more effective ...


  • 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 ...

  • 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 ...
