Special Issue Information
Dear Colleagues,
The growing global demand for energy necessitates innovative and sustainable approaches to hydrocarbon production. As the petroleum industry evolves through technological advancements and a deeper understanding of Earth's geology, the challenge of accessing remaining oil reserves becomes increasingly complex. With conventional and easily accessible petroleum sources depleting, the need for enhanced oil recovery (EOR) methods—both conventional and unconventional—has become more critical than ever.
EOR techniques aim to maximize oil extraction from mature reservoirs, extending their productive life and improving overall recovery rates. Conventional EOR methods, such as thermal recovery, gas injection, and chemical flooding, have been widely employed to increase oil mobility and production. Meanwhile, unconventional EOR strategies continue to emerge, incorporating innovative technologies and new insights into reservoir behavior to optimize recovery in complex geological formations.
The effectiveness of enhanced oil recovery (EOR) is closely linked to structural geology, as it offers critical insights into subsurface deformations and reservoir characteristics. A thorough understanding of geological formations is essential for selecting and implementing the most efficient EOR techniques, ensuring both long-term reservoir integrity and environmental sustainability. However, a key challenge lies in addressing complex reservoir heterogeneity, which is often hindered by insufficient communication between geologists and engineers.
This Special Issue focuses on the latest advancements and the dynamic interplay between petroleum exploration, structural geology, and enhanced oil recovery. By bridging these disciplines, we aim to foster innovative solutions that address the challenges of modern hydrocarbon exploration and recovery, paving the way for more sustainable and efficient practices.
We invite researchers and industry professionals to contribute their expertise and insights, driving progress in this critical field.
Key topics of unconventional EOR techniques include the following: Electromagnetic heating, plasma pulse technology, nanotechnology-enhanced EOR, wettability alteration methods, foam-assisted gas injection, and enzyme-based EOR.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
