Recent Advances in Enhanced Oil Recovery for Unconventional Oil and Gas

Dear Colleagues,

The development of unconventional oil and gas resources, including shale oil, tight oil, and coalbed methane, has revolutionized global energy production. However, the low permeability and complex pore structures of these reservoirs present significant challenges for hydrocarbon recovery. Many countries have invested considerable capital in enhancing the recovery of these unconventional resources.

Enhanced oil recovery (EOR) technologies aim to improve hydrocarbon recovery by altering the physical or chemical properties of the fluids within a reservoir or by modifying the permeability of the reservoir rock. Recently, advancements in science and technology, along with in-depth research, have led to significant progress in EOR methods, including thermal, chemical, gas injection, and microbial methods and other techniques that are widely employed in oilfield development. However, EOR still encounters numerous bottlenecks and challenges related to geology and engineering during practical application. Geological factors are the fundamental properties of hydrocarbon reservoirs, while engineering factors are closely linked to geological factors and cutting-edge techniques.

This Special Issue will synthesize recent advancements in EOR for unconventional oil and gas from both geological and engineering perspectives. We sincerely invite those with relevant expertise to submit original articles or reviews that address EOR for unconventional oil and gas, especially by integrating geological and engineering theories and methodologies. We look forward to receiving your submissions.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
