Special Issue Information

Dear Colleagues,

The petroleum industry is continually evolving, driven by technological advancements and a deepened understanding of Earth's geology. These developments consistently redefine the boundaries of oil and gas exploration. However, as our expertise in various domains improves, the once-abundant and easily accessible petroleum reserves are dwindling. Furthermore, the pressing challenge facing our civilization is to devise sustainable exploration strategies while addressing concerns such as carbon sequestration.

This Special Issue on petroleum exploration and structural geology delves into the latest research, methodologies, and case studies, highlighting the intertwined relationship between the examination of Earth's structures and the search for concealed hydrocarbon reserves. Structural geology, which sheds light on Earth's layer deformations, provides invaluable insights into locating and accessing petroleum reserves.

In this Special Issue, we invite authors to present their groundbreaking findings, breakthroughs, and narratives, with the aim of fostering a comprehensive understanding of the nuances and challenges in contemporary petroleum exploration.

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. 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.

Benefits of Publishing in a Special Issue

Detailed recognition of the paleoenvironment of sedimentation for the monotonous series of heterolithic sediments of the Machow Formation in the central part of the Carpathian Foredeep is still relatively poor. This study presents an unconventional approach of integrating results of seismostratigraphic interpretation with conclusions from analyses of chemostratigraphic profiles in boreholes. The results obtained from the studies allowed the resolution of the seismic data to be increased, enabling it to be accurately tied to the well data. The studies showed a high consistency between results obtained by the two methods mentioned above, and their combination provided a range of additional information and conclusions that could not be drawn from using a single method. The possibility of correlating interpreted sedimentary sequences with specific elements of the paleoenvironment and stages of the depositional history of the analyzed sedimentary basin was also demonstrated. An important benefit of the integrated interpretation methodology used is the possibility to recognize an apparently monotonous profile of heterolithic formations, which was previously not possible with standard interpretation methods.

In a mature middle and lower Gharif field in Oman, uncertainties surrounding initial water saturation and early water breakthroughs of unknown sources and paths suggest the presence of significant bypassed oil. In order to determine the areas with remaining oil, petrophysical and logging data of seven wells were processed using Techlog software and imported into Petrel software for modelling and simulation. Porosity was calculated using the Electric Propagation Time log and was utilized to evaluate the presence of oil, particularly in the upper tight zone of the formation. Despite the low resistivity readings in the highly porous layers, caused by good network connectivity and high formation water salinity, the resistivity contrast was sufficient to differentiate them from the oil zone. However, the calculated water saturation (Sw) in the tight top oil zone was high, consistent with the observed water production in the field. To improve the match between production data and simulation results, sensitivity analyses were conducted on various permeability anisotropy and relative permeability values within the model. The analyses showed that core-derived permeability anisotropy (vertical to horizontal ratio of 1:1) yielded a better history match for water production compared to the conventionally used value of 1:10. Water saturation maps were generated at the start and the end of production to highlight saturation distribution within the reservoirs. The maps revealed that in the lower porous part, the oil was fully depleted around the wells but remained trapped in the undrilled areas. Full article
