  • 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 ...

  • 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 ...

  • Optimize your completion by reducing proppant embedment

    Choosing the right proppant for the right application, instead of using the same proppant in every hydraulic fracturing application, can reduce cost per BOE. In a clay-rich, soft formation, for example, proppant choice is vital to reduce embedment. What is embedment? When completing a well in a clay-rich formation, such as the Niobrara in northeastern Colorado and adjacent parts of ...

  • 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 ...

  • 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. ...

  • 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 ...

  • 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 ...

  • State of Oil and Gas Production & Methods for Produced and Flowback Water Treatment - White Paper

    FRACTURING MEANS CLEAN ENERGY AND ECONOMIC GROWTH For over 60 years, hydraulic fracturing (fracking) operations have safely and successfully delivered the oil and natural gas needed to answer our nation's demand. In 2011, the US House of Representatives Committee on Energy and Commerce reported that, "Hydraulic fracturing has opened access to vast domestic reserves of natural gas that ...

  • 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, ...

  • Taking the pressure off desalination

    California-based PAX Pure hopes to offer a new solution to water scarcity with its groundbreaking water purification tool. Developed by Jay Harman and Tom Gielda, PAX Pure technology desalinates and demineralizes water without membranes, moving parts or chemicals. Instead, the technology simply mimics high-altitude conditions. The big challenge with conventional ...

  • 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 ...

  • Development and application of type curves for pressure transient analysis of horizontal wells in shale gas reservoirs

    Even though significant progresses have been made in the past few years, there appears to be a lack of information regarding the characterisation of shale gas formations. A major purpose of this study is to demonstrate impacts of horizontal well geometries and gas flow parameters as well as shale gas reservoir system on horizontal well production behaviour and flow regime on pressure transient ...

  • 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 ...

  • 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 ...

  • Health alert over fracking’s chemical cocktails

    Fracking is once again in trouble. Scientists have found that what gets pumped into hydrocarbon-rich rock as part of the hydraulic fracture technique to release gas and oil trapped in underground reservoirs may not be entirely healthy. Environmental engineer William Stringfellow and colleagues at Lawrence Berkeley National Laboratory and the University of the Pacific told ...
