  • Fracking & Shale Gas

    Unconventional natural gas production (shale gas) by hydraulic fracturing - Quantification of the Environmental Footprint Due to the global decline of fossil energy reserves and resources, unconventional natural gas production has become increasingly important in the last decade. In this context, unconventional natural gas production means the production of shale gas, tight ...

  • Living near a fracking well means more asthma attacks

    It's probably telling that the word ‘fracking’ sounds just shy of a curse word. Researchers at the Johns Hopkins Bloomberg School of Public Health have found that people who live near active, unconventional natural gas wells operated by the fracking industry were significantly more likely to suffer from asthma attacks. It’s the latest in a string of studies that has linked the ...

Goldstein is senior vice president, water and environmental systems at Louis Berger. He recently shared his insights with us on fractured rock characterization and what he is looking ...

  • Locating Groundwater Wells for Fracking Operations in West Texas - Case Study

    In June 2014, our clients used AGI resistivity imaging tools to successfully locate a 125-gallon-per-minute groundwater well in West Texas as well as geohazards that could, if left unlocated, cause significant damage to property and increase costs. Process Our clients used the ...

  • Removal of calcium and magnesium ions from shale gas flowback water by chemically activated zeolite

    Shale gas has become a new sweet spot of global oil and gas exploration, and the large amount of flowback water produced during shale gas extraction is attracting increased attention. Internal recycling of flowback water for future hydraulic fracturing is currently the most effective, and it is necessary to decrease the content of divalent cations for eliminating scaling and maintaining ...

  • Solution blooming for fracking spills?

    Blooming salts may clean up after brine spills North Dakota's oil boom can have a salty side-effect. Wastewater from oil drilling and hydraulic fracturing – or fracking – is often laden with salts and can spill, contaminating soils. In 2014, for example, 42 such brine spills per week, on average, were recorded in North Dakota. Brine spills introduce so ...

  • World Oil: Proppant-sized solid inhibitors improve flow assurance in fraced wells

    The economic value of a hydraulically fractured well is highly dependent upon flow assurance—that is, maintaining unimpeded flow of hydrocarbons from the formation to the surface. Flow assurance issues occur in hydraulically fractured wells, as a result of the deposition and buildup of naturally occurring particulates that are present in the system during hydrocarbon production. Scale is ...

  • Barnett Shale Fault Detection

    OBJECTIVE OF THE PETRO-SONDE SURVEY: To delineate faults within Barnett Shale Barnett Shale deposits within the Ft. Worth Basin produce primarily gas from fracture porosity. Strata in the Johnson county area dip and thicken to the northeast in response to the Central Texas uplift bordering the Ft. Worth Basin to the southwest. Faulting is common in the area and generally trends NW-SE. To ...

  • 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 ...

  • INCREASED OIL COMPETITION: SURVIVAL OF THE FITTEST

    Is the U.S. shale oil industry in trouble? No, it is engaged in a high-stakes competition for market share. As oil flooded the market in 2014-15, prices dropped dramatically and producers began burning midnight oil to manage the downward economic pressures. While some overleveraged companies won’t survive the economic challenge, in true Darwinian fashion, the fittest will prevail. ...

  • 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 ...

  • 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 ...

  • The value of fracking wastewater treatment and recycling technologies in North Dakota

    The oil boom in North Dakota is aided by hydraulic fracturing, often referred to as fracking. Fracking uses a pressurized water, sand, and chemical mixture to break through layers of rock and release oil and gas. This procedure produces hundreds of truckloads of wastewater for each fracked well. In this study, we analyze the financial feasibility of a system of wastewater recycling and reuse to ...

  • The Middle East should think twice about fracking

    Securing energy resources is critical for fuelling development, but deciding which types of energy to invest in will affect a country’s future in many ways — and not all are good when it comes to shale gas. Four countries in the Middle East and North Africa (MENA) ...

  • Why many experts missed this: Cheap oil can hurt US economy

    WASHINGTON (AP) - If there was one thing most economists agreed on at the start of the year, it was this: Plunging oil prices would boost the U.S. economy. It hasn't worked out that way. The economy is thought to have shrunk in the January-March quarter and may barely grow for the first half of 2015 - thanks in part to sharp cuts in energy drilling. And despite their savings at the gas pump, ...

  • Persistent Drought Challenges Fracking

     Feature Article CleantechIQ.com - Executive Commentary Freshwater has historically been the base fluid essential for fracking, sweeping, and oil sands recovery because it has been abundant and readily available, and because of its low cost. Unfortunately, all of that is now changing due to a longer than expected global drought, and the industry is examining new options and ...

  • Managing the impact from shale gas drilling

    Shale gas has transformed the energy market in the United States where drilling is underway in 17 states, with more than 80,000 wells drilled or permitted since 2005. Deposits elsewhere in the world are under varying degrees of exploration. The main environmental impacts of the process are water usage, waste water management, methane emissions, groundwater and soil contamination. These are ...
