In 2012, the quarterly Wiertnictwo Nafta Gaz was transferred into AGH Drilling, Oil, Gas and in 2021 into Journal of Geotechnology and Energy. As a result of this development, the thematic scope of accepted articles has been broadened.</p> <p>We publish original articles concerning theoretical and applied research. Discussion and review papers presenting the current state of the art as well as new and emerging scientific ideas are also welcomed. Main areas of interest of the journal are: energy, geomechanics, geotechnics, drilling, reservoir engineering, geology, petroleum engineering, logging, management and protection of reservoirs, geothermal energy, groundwater, natural gas industry, hydrogen energy, CCS/CCSU, sustainable energy and environment.</p> <p>Articles are published in <strong>English. </strong><span data-contrast="auto">Publication of scientific articles in Journal of Geotechnology and Energy is </span><strong><span data-contrast="auto">free of charge</span></strong><span data-contrast="auto">, while our journal is non-profit.</span></p> <p><span data-contrast="auto">Journal of Geotechnology and Energy is sponsored in full by AGH University of Krakow and published by <a href="https://www.wydawnictwo.agh.edu.pl/en">AGH University Press</a>.</span></p> en-US jge-office@agh.edu.pl (JGE Editorial Office) ojssupport@wydawnictwoagh.pl (Technical Support) Mon, 30 Sep 2024 17:28:37 +0200 OJS 3.2.1.4 http://blogs.law.harvard.edu/tech/rss 60 Impact of the Geometrical Configuration of Electrical Submersible Pump Impellers on Run Life and Sand Stuffing: A Case Study and Recommended Practice https://journals.agh.edu.pl/jge/article/view/6323 <h1>The objective of this study was to identify the root cause of the premature frequent failures of electrical submersible pumps, in a particular oil field, aiming to extend their run lives so oil deferment, liquid lifting costs, and unit production cost are reduced. Dismantle, inspection, and failure analysis (DIFA) approach was used to visually inspect the pumps to identify the cause of failure. The inspection inferred that the failures were mainly due to sand accumulation (stuffing) in the impellers of radial flow pumps, while it was not observed in the mixed flow impellers that have shown good performance at the same well conditions. This finding was then experimented on many wells and proved to be correct as demonstrated in this paper. &nbsp;Eventually, the result of this research was technically proved as being attributed to the geometrical shape of the impeller flow path, the study has correlated sand stuffing failure with flow path geometry of the impellers. The study projected these results to an established specific speed model (N<sub>s</sub>) and recommends a pump sizing approach for mild sand-producing oil wells to cater for the geometrical flow configuration of the pump impellers.</h1> Masaad Eltigani Copyright (c) 2024 Journal of Geotechnology and Energy https://journals.agh.edu.pl/jge/article/view/6323 Mon, 30 Sep 2024 00:00:00 +0200
