Interpretation of the Results of Deep Geothermal Drilling Projects at Gediz Graben 

Assist. Professor Fatma Gülmez  of  Department of Geological Engineering and her colleagues' research benefit academia and industry by interpreting the results of deep geothermal drilling projects within the context of regional geology.

The study published by Dr. Fatma Gülmez from Geological Engineering Department and her colleagues including Hatice Ünal Ercan, Nalan Lom, Gönenç Göçmengil, and Emre Damcı, highlights the importance of collaboration between industry and academia. Their study which interprets the results of deep geothermal drilling projects carried out by a national company (Özmen Holding) within the context of regional geology, is an important example of the mutual benefits of such partnerships between academia and industry.

I4.2-897 – Cascading Multi-Segment Faults Triggered by Supershear Rupture During the 2023 SE Türkiye Earthquake Doublet: A Giant Jigsaw Puzzle Mobilized

Abstract: A devastating earthquake doublet occurred on 6 February 2023 with moment magnitudes of Mw 7.9 and Mw 7.7 along the East Anatolian Fault (EAF) and Sürgü-Çardak Fault (SCF), respectively. The 2023 earthquake sequence resulted in catastrophic human life and economic loss, and caused majör impacts to infrastructure throughout south-east Türkiye and north-west Syria. The kinematics of ruptures for the doublet were complex involving multi-scale cascading rupture growth across the hybrid fault segments. We find that the first earthquake (Mw 7.9) nucleated on a previously unmapped fault, Nurdağı-Pazarcık segment, before transitioning to the EAF leading to supershear bilateral ruptures on the initial branch, Pazarcık and Erkenek segments and subsh segment. The dynamic stress of the leading branch rupture impulsively triggered the EAF segments accelerating the following bilateral supershear rupture of the second earthquake (Mw 7.7) along the curved fragments of the SCF with dominant westward rupture directivity, and stopping instantly at geometric barriers at both ends of the fault. Hence, the geometry and pre-stress level of multiple segments heightened the diverse rupture characteristics of the 2023 south-east Türkiye earthquake doublet, contributing to the strong ground shaking and associated devastation and amplified the ground shaking intensity.

          




Investigation of High-Efficiency Recovery of Rare Earth Elements from Permanent Magnetic Materials”, Granted Support from BAP-General Research Project

A project lead by Assoc. Prof. Birgül Benli from the Department of Mineral Processing Engineering was granted support from BAP-General Research Project, titled: Investigation of High-Efficiency Recovery of Rare Earth Elements from Permanent Magnetic Materials using Deep Eutectic Solvents and Eutectic Freezing Crystallization (Project ID: 45070).

The Project focuses on an eco-friendly dissolution technology using deep eutectic solvents to recycle scrap magnets from electric and hybrid vehicles containing REEs (Rare Earth Elements). The subsequent eutectic freezing crystallization aims to recover REEs in high purity. With approximately 3 kg of NdFeB magnets in each new electric or hybrid vehicle, our goal is to minimize environmental impact during magnet recycling, utilizing eco-friendly solvents and technologies for a high-value secondary source.

In the project, Assist. Prof. Fatma Elif Genceli Güner and Ph.D. (c)  Ayşe Gül Okumuş Ermiş from the Department of Chemical Engineering, along with M.Sc. (c) Ali Cemal Tanrıkulu and undergraduate student Mert Sarıkaya, are also contributing as researchers.



Guest Editorship

Assoc. Prof. Dr. Emre Artun of the Department of Petroleum and Natural Gas Engineering  acted as one of the guest editors of  a special issue entitled “Intelligent and Fuzzy Systems for Petroleum Science, Engineering and Green Transition Applications in the Petroleum Industry” published at the Journal of Petroleum Science and Engineering Energies, Frontiers in Earth Science. 





New Patent Awarded

Our faculty member Prof. Dr. Sedat İnan of the Department of Geological Engineering has been granted the US patent on his work related to Oil API determination of reservoir rocks by oxidation. More information on this technique can be found  as follows:

Oil API determination of reservoir rocks by oxidation

US Patent number: 11639921

Inventors: Sebastian Robert Glynn Henderson, Sedat İnan

A method of determining an API gravity of a crude oil is provided. The method includes obtaining a reservoir sample containing the crude oil and heating the sample to a first temperature using an oxidative testing apparatus. The sample is then heated to a second temperature, which is greater than the first temperature, over a period using a fixed heating rate. The rate of carbon dioxide emission from the sample is detected during the period of heating to the second temperature. The peak rate of carbon dioxide emission from the sample is then determined and the peak carbon dioxide emission temperature associated with the peak rate of carbon dioxide emission is also determined. The API gravity of the crude oil in the reservoir sample is determined using an empirical correlation between API gravity and the peak carbon dioxide emission temperature associated with the fixed heating rate.



The Department of Geophysical Engineering has Contributed to Polar Sciences Encyclopedia Published by TUBITAK with hree Articles

Energy Source Gas Hydrates”, “Exploration of Gas Hydrates” and “Production of Gas Hydrates” articles in the 3-volume Polar sciences encyclopedia published by TÜBİTAK were written by Prof. Dr. Neslihan Ocakoğlu Gökaşan and Prof. Dr. Doğa Doğan from the Department of Geophysical Engineering. These articles consisting of the research and introduction of gas hydrates, known as the energy source of the future in the poles, with geophysical methods, will open a new horizon in earth sciences.

İTÜ Faculty of Mines

maden-anasayfa-hakkimizda

The Faculty of Mines was established in 1953 in Istanbul. At its first years, the faculty composed of mainly Turkish and German professors, and its program was similar to those days’ famous mining schools such as Aachen, Clausthal and Freiberg.

Today, the Faculty of Mines with five departments (Mining, Geological, Petroleum and Natural Gas, Geophysical, and Mineral Processing Engineering) and 13 sub-divisions is graduating young and proficient engineers to search, develop and produce underground sources of Turkey.
