  • Utilisation of shale oil by the extraction and retorting of oil shale

    Extraction of the bitumen fraction of oil shale was carried out using two different solvents, chloroform and toluene. Oil shale of 4.0 mm particle size from the El-Lajjun area in Jordan was used in this study. The solvents were recovered by distillation. The spent shale was retorted using a special retort and shale oil (Kerogen) was recovered. The quantity of the hydrocarbon was compared with ...

  • 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 ...

  • Ecological efficiency of the oil shale electricity sector of Estonia

    Estonia is a typical postsocialist country with an inefficient energy sector, albeit uniquely based on oil shale mining and burning. This article comprehensively analyses the efficiency of the oil shale energy industry from mining to end use. The overall efficiency of oil shale energetics was estimated to be less than 20% (17% in 2002), with the losses attributed to wasting of co-produced thermal ...

  • Estonia eager to teach world about oil shale

    AUVERE, Estonia (AP) — Home to the creators of Skype and the first country to use online voting, Estonia relishes its image as a technological pioneer. But the tiny East European country's most far-reaching economic achievement could come from how it has learned to squeeze oil from a rock. About 200 feet (60 meters) below ground in northeastern Estonia, very close to the Russian border, ...

  • A shale gas revolution?

    MIT report shows prosperous shale gas market could hurt future R&D, if we let it. By Vicki Ekstrom, Joint Program on the Science and Policy of Global Change, MIT Shale gas - a resource that has grown significantly in just the last few years to one-quarter of the domestic gas supply - is cheaper and involves fewer emissions than traditional coal or oil. But recent ...

  • Experimental investigation of effects of oil shale composition on its calorific value and oil yield

    This paper reports results of a detailed geochemical analysis carried out on representative oil shale samples obtained from the Attarat Um Ghudrandeposit, in Jordan. The conducted tests aimed to determine main features of the studied samples, such as oil yield, calorific value, organic and inorganic composition and moisture content. Based on obtained results of a large number of oil shale ...

  • 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 ...

  • 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 ...

  • New technologies for processing high sulphur oil shales and producing highly priced thiophenes

    A technology for processing the light fraction of high sulphur oil shale pyrolysis tar is suggested. The technology allows some industrial hydrocarbon solvents, chemical reagents and sulphur-organic products (for example, thiophene, methyl- and dimethilthiophenes), which are used in organic synthesis, to be obtained and the production of different medical preparations etc.Keywords: Oil shale, ...

  • Energotechnological oil shale utilisation by means of an SHCU - a low waste and environmentally sound technological process

    This paper presents the calculated data on the emissions into the environment from the low-waste energotechnological solid heat carrier units (SHCUs) working with oil shales. A comparison of this technology with direct oil shale combustion at a power plant was carried out using the example of an Estonian power plant. The energotechnological plant (ETP) including two units SHCU-3000 with an oil ...

  • 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 ...

  • What do oil sands and shale gas have in common? Acute need for sustainable water management solutions

    The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

  • 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 ...

  • Digital Technologies & Current Uses in Environmental Geology - A Marcellus Shale Example

    The Marcellus Shale play has been of significant importance in the development of oil and gas resources and providing regulatory framework for natural resource protection. Pennsylvania has led in updating oil and gas regulations to manage these unconventional resources. The use of digital technologies now underlies effective collection, storage, analysis and reporting of data and information ...

  • 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 ...

  • Shale Gas: Time to look before we leap any further

    Shale gas is a game-changer for global energy supply. It is already transforming the U.S. energy outlook, and is expected to deliver over 40% of domestic gas production by 2025 (Figure 1). Other countries and regions, notably Europe and China, may soon follow suit, in a repeat of the early 20th century oil rush. Opinion is bitterly divided, however, over the environmental risks and benefits of ...
