Special Issue "Unconventional Natural Gas (UNG) Recoveries"
A special issue of Energies (ISSN 1996-1073).
Deadline for manuscript submissions: closed (15 December 2016)
Our energy resources are crucial; but they are under pressure from growing populations, urbanisation, and economic prosperity. By 2040, global demand for energy will increase by 40% over present levels. By then, it is forecast that approximately 75% of energy demand will still be met by fossil fuels—but oil and coal will have lessened in importance due to tight regulation and advances in more environmentally friendly alternatives. Which newer fossil fuel will emerge to dominate in the next few decades? There is one clear answer: Natural gas
Despite the challenges, climate change legislation and regulation to limit greenhouse gases have already allowed natural gas to compete favourably with oil and coal. It is now ranked third among the world’s major energy sources; and it is the cleanest and the richest in hydrocarbons, offering high energy-conversion efficiencies for power generation.
Conventional gas is easy to harvest. It has been produced across the world in the last few decades, so its reserves are now rapidly depleting. In contrast, the earth holds huge untapped reserves of unconventional—but locked within compact rocks, such as shale, coal seams, and tight sandstones.
The greatest challenge for exploitation of unconventional natural gas (UNG) is very low recovery rates, because of low permeability in its deep reservoirs. Reducing the complexity in exploration targets, using suitable exploration and production technologies (such as new stimulation technologies to prompt release of the gas), has potential to release vast quantities of UNG from highly impermeable formations. However, unique conditions in UNG reservoirs call for innovative technologies founded securely on new science. This proposal calls for papers in the areas of new sciences developed to enhance the recovery process of gas from coal seams, shale, and tight formations.
We will therefore especially welcome submissions on the following topics:
- Gas flow and diffusions of coal seams, shales, tight gas reservoirs
- Techniques to enhance gas recoveries, such as hydro fracking and innovations in well drilling
- Caprock integrity and associated environmental issues
- Coupled hydro-chemico-mechanical processes
- Reservoir geomechanics, and wellbore and drilling mechanics
- Constitutive modelling and numerical methods
- Numerical modelling of THM
- Adsorption/desorption characterises of rocks
- Case studies of international interest
- Any other relevant research areas in Unconventional Natural Gas domain

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
