1. Objectives and focus of the special issue
Despite the major contribution of conventional oil and gas to worldwide energy supply, both shale and tight oil and gas have made a significant impact on worldwide energy supply and markets over the past decade or so. The rapid growth in so-called “unconventional oil and gas” production from several North American basins has played a decisive role in precipitating the glut that has put downward pressure on oil and gas prices beginning in 2014. Ongoing and expanding production from unconventional oil in China is likely to have an increasing impact on Asian markets.
Meanwhile, the exploration and development of natural gas hydrates, geothermal energy and other renewable energy sources in the Americas and in Asia is likely to grow and its contribution to worldwide energy supply may further disrupt existing energy markets. This is despite the large associated investments and operational cost that hamper the further expansion of the recovery of unconventional oil and gas resources, but also public concerns of “fracking” and “induced seismicity” that have become amplified by its opponents. This has led to restrictions against the development of unconventional resources in many areas, and outright bans in some jurisdictions (e.g., France, Germany, and New York).
Furthermore, the expansion and diversification of renewable and alternative energy sources that are more-environmentally-friendly, and their promotion by both governments and the public, are placing pressure on communities to question their dependence on fossil fuels. This awareness has fuelled the debate on the sustainability of unconventional oil and gas resources, despite its increasing impact on the world energy economy. Rigorous and transparent scientific and engineering studies are urgently required to identify, modify, and apply improved techniques that can demonstrate that unconventional and alternative energy sources can be recovered on a large scale in an economically-viable and environmentally-friendly manner.
These pressing issues and requirements are motivating worldwide debate and discussion on the trade-off of risks and opportunities associated with unconventional oil and gas resources. This includes the compilation and dissemination of ongoing research and advances in industry practices to address related challenges and problems. This special issue aims to bridge the gaps among fundamental theories, applied technologies and field practice to study recent and new advances related to the sustainable development of unconventional energy resources through multi-disciplinary efforts.
This special issue will consider for inclusion technical papers on various topics, including, but not limited to, unconventional oil & gas, natural gas hydrates, geothermal resource exploration and assessment, drilling, completions, production, enhanced recovery processes, environmental risks and hazards, and related regulatory and policy developments.

2. Invitation to contribute
We invite prospective authors working in unconventional oil and gas, natural gas hydrates and geothermal energy in the broad disciplinary areas of petroleum engineering, geology, geophysics, geochemistry, chemical, mechanical and thermal engineering, environmental sciences, policy and strategy, to contribute to this special volume on “Sustainability of Worldwide Unconventional Oil, Gas and Energy Resources: New Advances & Challenges” with original, full-length research articles, experimental studies, review articles, case studies and discussions. Potential topics include, but are not limited to:
1. New discovery and evaluation of significant global unconventional oil & gas, natural gas hydrate and geothermal resources, and their associated distributions and challenges.
2. New theories and mechanisms of generation, migration, accumulation and storage of unconventional oil & gas, gas hydrate and geothermal reservoirs, and their associated mineralogy, depositional history and geological characteristics.
3. Novel theories and advanced techniques of sub-surface measurements (geological, geophysical, petrophysical, geochemical, geomechanical, well logging, seismic assessment and well testing) and their interpretation.
4. Advances in well drilling and completion techniques, including drilling mud, fracturing fluids, proppants, stimulation methods, tools and designs.
