Special Issue Information

Dear Colleagues,

The 16th International Congress of the Geological Society of Greece will take place at the University of Patras, Greece, from October 17–19, 2022. The Congress will be organized in a face-to-face setting, aiming to bring together academics, researchers, research students, and industry from around the world to share their knowledge, experience, and research results on all aspects of geosciences with prime focus on, but not limited to, the eastern Mediterranean area. We expect young researchers to meet with senior scientists in an effort to meet experience and expertise. Highly respected keynote speakers will open the sessions.

Demand for oil and gas is growing worldwide, and as a natural consequence, a secure supply of adequate and reliable energy at an affordable price is of great importance for economic growth and prosperity. Both oil and gas have been the world's major commercial energy sources for many decades, and there is a consensus view that they will maintain this leading role well into the 21st century. The global supply of crude oil, other liquid hydrocarbons, and biofuels are expected to be adequate to meet the world's demand for liquid fuels for at least the next 25 years.

This section of Geosciences considers that multi-faceted, interdisciplinary research is prerequisite for the advancement of the subject area. Therefore, research papers that integrate results from a diverse range of disciplines are highly encouraged. The submitted papers are expected to link research with broader implications, rather than being principally descriptive and localized.

All articles published in this Special Issue must be related to the abstracts submitted in the special session S17 of the 16th International Congress of the Geological Society of Greece entitled “The Hydrocarbon prospectivity of SE Mediterranean: targets and opportunities” (https://gsg2022.gr/special-sessions). Full papers should be submitted at the email addresses of the guest editors before the deadline of 31/9/2022. Three selected by the Guest Editors high-impact original research articles will be published free of charge, while a 50% discount will be provided for an additional five (5) articles for their publication. This will be a dynamic Special Issue, in which articles will be published as soon as the reviewers and editors are ready to accept them, without waiting for the deadline for the entire Special Issue to arrive. Gratefully acknowledged by the Organising Committee of the 16th International Congress of the Geological Society of Greece, the publication fees for the papers are kindly being sponsored by Geosciences.

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. Geosciences 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 1800 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.

An Integrated Approach for the Thermal Maturity Modeling Re-Assessment of an Exploration Well in the Hellenides Fold and Thrust Belt

Utilizing geological and geochemical data, we re-assessed the thermal maturity of the Lower Cretaceous Vigla shales of the AY-3 well, located in the Internal Ionian geotectonic zone of Greece, using 1D thermal maturity modeling. Vigla shales primarily containing kerogen type I to II, incorporated within alternations of carbonates, cherts, and marly limestones, were selected as the main source rock intervals. Biomarkers and Rock-Eval data were used on top of vitrinite reflectance data for the calibration of the 1D model. Hopane and sterane isomerization ratios for the Vigla shales appear to hold values of 58–64% and 44–49%, respectively, while vitrinite reflectance ranges from 0.61% to 0.71% and Tmax between 431 and 451 °C. One-dimensional thermal maturity modeling suggests that lower Cretaceous Vigla shales entered the oil window in early Miocene times and reached the expulsion onset during the middle Miocene. Additionally, thermal modeling estimates the overburden eroded thickness to range between 2.1 and 2.6 km. This unravels the pre-eroded shape of this part of the belt of Miocene times alongside the burial history of the area and its evident relation to the hydrocarbon potential. This assessment comprises a step towards the understanding of the belt and the different timings of hydrocarbon generation in the External Hellenides. Full article

As Lower Cretaceous “Vigla” shales have been suggested as one of the main source rocks for the Ionian Basin in Greece, a geochemical analysis was performed for “Vigla” shales in Kastos Island and the Araxos peninsula, far from the already studied areas. Results, based on Rock-Eval VI analysis, sample fractionation, and biomarkers analysis, showed that the studied rocks could be of low production capacity, are type II/III of kerogen, and can produce liquid and gas hydrocarbons for Kastos Island. Organic matter (total organic carbon-TOC 0.02–3.45%) of the studied samples is thermally immature, in the early stages of diagenesis, and was accumulated in an anoxic environment. Additionally, the geochemical analyses confirmed the combination of marine and terrestrial origin of the organic matter. On the other hand, TOC (0.01–0.72%) from the Araxos peninsula shows fair oil potential and type IV kerogen. The results based on the Odd–Even Predominance, OEP (27–31), OEP (2), and OEP (1), valued for samples AG1, AG2, AG5, and AG6, indicated an anoxic deposition environment. As the Ionian Basin was sub-divided into three sub-basins (internal, middle, and external) during its syn-rift evolution, different depositional conditions were developed from one sub-basin to the other, with different sedimentary thicknesses within the same sub-basin or among different sub-basins and with different amounts of TOC. The fact that there is a great difference in geochemical indices between the two studied areas during the same period suggests that probable different depositional conditions could exist. It seems that the richness in Kastos Island could be related to the neighboring Apulian Platform, whereas the poorness in the Araxos peninsula could be related to the Gavrovo platform, or the differences could be related to restrictions produced regions. The comparison with previous studies indicates that different quality and quantity of organic matter could be accumulated either within the same sub-basin or from one sub-basin to the other.
