Multiphase Flow, and Efficient Development Methodology and Technology in Unconventional Reservoirs (2nd Edition)

Dear Colleagues,

Unconventional reservoirs, including shale and tight oil and gas, heavy oil, coal bed methane (CBM), natural gas, and fracture-vuggy carbonate reservoirs, are widely distributed and abundant around the world. This is an important area for the strategic replacement and development of oil and gas resources. In contrast to conventional reservoirs, the multiphase fluid flow law and the development process in unconventional reservoirs are more complex. The pore scales of unconventional oil and gas reservoirs involve centimeter, micron, and nanometer scales. The formation environment is mostly of a high temperature, high pressure, and high salinity. The flow of a fluid in a porous medium is also a rather complicated course, combining intricate phase variations. These issues have all contributed to the difficulties involved in oil and gas development and are attracting increasing attention from academics.

This Special Issue focuses on the sustainable development of unconventional oil and gas resources, recent advances, and the challenges they are facing for sustainability. We aim to gather researchers in the aforementioned fields to highlight the current development of novel techniques; exchange the latest knowledge regarding the underlying mechanisms; present advanced algorithms for modeling and innovative experimental methods; and facilitate collaboration between researchers in different fields. We welcome the submission of both original research and review articles.

Potential topics include, but are not limited to, the following:

• Multi-scale simulations of fluid flow in fracture-vuggy carbonate reservoirs;
• Adsorption and desorption in shale and CBM;
• New advances in natural gas hydrate development;
• Gas injection assisting heavy oil development;
• The efficient utilization of multifunctional foam fluid;
• CO₂-based enhanced oil recovery (EOR) in unconventional oil and gas reservoirs;
• CO₂ storage in abundant reservoirs.

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 submissions that pass pre-check are 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. Processes 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 2400 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.
