  • Q&A: will shale revolutionise gas?

    "If shale gas fails to deliver on current expectations, then in 10 years or so, gas supplies could face serious constraints." So says Paul Stevens, a senior fellow at the international affairs think tank, Chatham House. He's penned a report that raises serious doubts about whether shale gas will indeed deliver. So what is shale gas, why is it such a big deal, and what will ...

  • 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) ...

  • Top-down, intelligent reservoir modelling of oil and gas producing shale reservoirs: case studies

    Producing hydrocarbon from shale plays has attracted much attention in recent years. Advances in horizontal drilling and multi-stage hydraulic fracturing have made shale reservoirs a focal point for many operators. Our understanding of the complexities associated with the flow mechanism in shale has not kept up with our interest in shale formations. We present the application of a new reservoir ...

  • 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. ...

  • 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 ...

  • The Future For Fracking

    Summary -Fracking is an essential technology to meet growing global demand for oil and gas. -Fracking has become the "F" word, because it is very water-intensive, and has potential negative impacts on the environment. -The future of fracking will be constrained if adequate water is not available and if solutions for decontaminating wastewaters are not found. -Oil sands ...

  • 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 ...

  • Defining the Shale Gas Life Cycle: A framework for identifying and mitigating environmental impacts

    Life cycle assessments of shale gas activities differ in their findings. Among the various studies, researchers estimate different greenhouse gas emissions, rates of water use, and rates of wastewater production. Some of the variation in findings is due to the parameters of each study, particularly the life cycle boundary. The life cycle boundary determines which life cycle stages—and which ...

  • 5 Leading Drilling Waste Management Companies

    Drill cutting waste management as a separate niche has gained a lot of traction in recent times. This is true because post Shale Revolution, the hunt for oil and gas is on the rise and with it drilling waste disposal has become quite important. According to the American Petroleum institute, “Approximately 1.21 barrels of drilling waste is produced for every foot drilled in US”. If ...

  • 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 ...

  • Oil shale is not a viable fuel source - Study

    While many are celebrating the end of the 'Peak Oil' concerns because of abundent new sources of oil in shale deposits, a true accounting for all economic and environmental costs to exploit this energy source suggests it may not be a viable proposition at all. Scientists' best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional ...

  • 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 ...

  • Water reclamation from shale gas drilling flow-back fluid using a novel forward osmosis–vacuum membrane distillation hybrid system

    This study examined the performance of a novel hybrid system of forward osmosis (FO) combined with vacuum membrane distillation (VMD) for reclaiming water from shale gas drilling flow-back fluid (SGDF). In the hybrid FO-VMD system, water permeated through the FO membrane into a draw solution reservoir, and the VMD process was used for draw solute recovery and clean water production. Using a SGDF ...
