Application of Gel for Water Shutoff: A Case Study of Kelebija Oil Field
This paper focuses on the results of water shutoff operations using DSGA polymer gel in the Kelebija oil field. The methodology of candidate wells selection and the manner of performing the operation will also be included. The Kelebija oil field is characterized by a complex reservoir system with heterogeneous layers of different permeability and dual porosity, which led to the early breakthrough of water. For the last 25 years, average water cut was above 90%. Implementation of water shutoff ...intervención de pozos petroleros, reservoir characterization, production control, well logging, downhole intervention, enhanced recovery, complex reservoir, reservoir surveillance, water shut-off, upstream oil & gasIrina Zahirovic, Petar Skrobonja, Dušan Danilović.

Tracking of the temporal dependency of fading of the human footprint temperature contrast
In certain situations, it is extremely important to determine the exact time “someone” entered or crossed the forbidden zone of a military or strategic installation, a red zone of radioactive, chemical, or biological contamination, a bank or similar structure. Standard security measures include ordinary video surveillance using cameras that operate in the visible range of the electromagnetic spectrum, as well commercial thermal imaging cameras [1, 2]. The paper presents the results of experiments that suggest another possible use of ...Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Darko Vasiljević, Danica Pavlović.

Failure Estimation of the Majdanpek Open Pit East Face Based on Inverse Velocity Model
The Majdanpek open pit mine south district is currently active mining prospect of copper ore exploitation in eastern Serbia. Its depth is approaching the termination depth and occurrences of large-scale instabilities and global instability of the final pit slope is possible. These can generate catastrophic mass movement inside an area that encloses a regional road route and the Pek River bed which is channelled along the outer contour of the pit. The displacements that were noted in early 2023, in the ...Miloš Marjanović, Stefan Milanović, Nikola Simić, Lazar Kričak.

A hundred years of Milutin Milanković's climate change theory - geological implications
Dejan Radivojević (2020)Миланковићева теорија циклуса објављена пре сто година је најважнија теорија у наукама које проучавају климу и имала је велики утицај на дисциплине које се баве Земљом. Ипак, његов рад је чекао више од педесет година да би добио потврду. Може се рећи да Миланковићев рад највећи утицај на геологију има у изради астрономске временске скале, подршци хипотези континенталног дрифта и палеоклиматологији.
