  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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, ...

  • Not All Frac Sand is Created Equal

    Frac sand is the most commonly used proppant. The term “proppant” is used because it literally props open fractures enabling the oil or gas to flow out. Without proppant, there is no hydraulic fracturing, and without hydraulic fracturing there is no opening or stimulation of tight oil and gas plays. E&P (exploration and production) companies pump proppants based on ...

  • Utilizing unconventional water sources for industrial reuse

    Reclamation and reuse of unconventional wastewater sources for plant raw water, cooling water and process pre-treatment has increased substantially due to increases in the cost of drinking water, recurring water shortages that can impact business operations, and tightening government regulation. Water is required in almost every industrial sector for the processing and manufacture of products. ...

  • 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 ...

  • In Situ Physical/Chemical Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • MIOX bringing green tech to fracking

    Water purification firm MIOX Corp. is diving deep into the bowels of the oil and gas industry. The Albuquerque company, whose purification systems are used worldwide to clean water for municipalities and commercial businesses, will apply its technology for the first time to reduce toxicity and improve the efficiency of fluids that oil and gas companies use for hydraulic fracturing to crack open ...

  • Halliburton hunts new bacteria killer to protect Shale-gas boom

    Halliburton Co. and Schlumberger Ltd., trying to forestall a regulatory crackdown that would cut natural-gas drilling, are developing ways to eliminate the need for chemicals that may taint water supplies near wells. At risk is hydraulic fracturing, or fracking, a process that unlocked gas deposits in shale formations and drove gains in U.S. production of the fuel. Proposed regulations might slow ...

  • SEAB-issued recommendations present new challenges to shale gas industry

    The Secretary of Energy Advisory Board Subcommittee (SEAB) released its final report on Shale Gas Production, which calls on state, federal, and industry stakeholders to protect the environment while developing shale gas resources. The SEAB was charged by the U.S. Department of Energy and President Obama with drafting a report on immediate steps that can be taken to improve safety and ...

  • Questions And Answers About Saltwater Spills

    An estimated 1 million gallons of saltwater generated by oil drilling has leaked from a North Dakota pipeline, company and tribal officials say, and federal authorities are investigating whether any of the liquid reached Lake Sakakawea, one of the nation's largest man-made lakes. Here are some questions and answers about the spill and saltwater: Q: How does oil drilling produce ...

  • 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 ...

  • Answers to questions about oil waste in California aquifers

    California, the country's third-largest oil-producing state, has improperly given oil companies more than 2,500 permits to inject production fluids and oilfield waste into underground water supplies that are used for drinking water or irrigation, state records show. Nearly half of those disposal wells were approved or first started injections in the last four years under Gov. Jerry Brown, an ...
