Introducción: Las tasas de infección periprotésica, a veces, son subestimadas, ya que muchos casos de presunta falla aséptica pueden deberse a una infección no reconocida. Los objetivos de este estudio fueron: 1) estimar la prevalencia de cultivos positivos intraoperatorios inesperados, 2) determinar si las comorbilidades o los factores de riesgo de los pacientes tuvieron relación con la presencia de cultivos positivos inesperados, 3) determinar la supervivencia del implante en un seguimiento mínimo de12 meses.
Materiales y Métodos: Se realizó un estudio retrospectivo y observacional. En las historias clínicas electrónicas, se identificaron todas las revisiones de artroplastia total de cadera de una única institución entre 2014 y 2021. Resultados: De las 49 revisiones de artroplastia total de cadera en un tiempo, 9 pacientes (18,4%) tuvieron un resultado positivo inesperado. Los microorganismos aislados fueron: Staphylococcus aureus (3), Pseudomonas aeruginosa (1), Staphylococcus lugdunensis (1), Staphylococcus epidermidis (2), Staphylococcus haemolyticus (1), Streptococcus epidermidis (1). Ninguna comorbilidad tuvo significancia estadística para favorecer cultivos positivos inesperados en las revisiones asépticas. El 2% de la muestra, con un período de seguimiento de 49 meses, se reinfectó.
Conclusiones: Nuestro estudio arrojó una prevalencia de cultivos positivos inesperados del 18,4%. Ninguno de los factores de riesgo reportados en la bibliografía se asoció con un mayor riesgo de cultivos positivos inesperados, excepto los niveles altos de velocidad de sedimentación glomerular. Nuestros hallazgos son compatibles con los publicados y sugieren que los cultivos positivos inesperados en revisiones presumiblemente asépticas no tienen consecuencias significativas en la supervivencia del implante.

Introducción: Una de las complicaciones más importantes de la artroplastia total de cadera en el tratamiento de las fracturas es la luxación, con una tasa del 10%, cinco veces mayor que la de la artroplastia total de cadera por osteoartrosis. El objetivo de este estudio fue conocer nuestra incidencia de luxación en pacientes sometidos a artroplastia total de cadera por fractura del cuello femoral y evaluar la causa de la luxación.
Materiales y Métodos: Estudio retrospectivo en 110 pacientes sometidos a artroplastia total de cadera por fractura medial de cadera (edad promedio 69 años; 71% mujeres). Se evaluaron el tipo de fijación de la prótesis, el tamaño de la cabeza, el offset y el abordaje quirúrgico. Se midieron los ángulos de inclinación y de anteversión acetabulares y se registraron las comorbilidades.
Resultados: El 72% de las cirugías fueron por vía posterolateral. La vía anterolateral se asoció con una copa 7° más vertical (p = 0,001). El 65,4% de las cabezas eran de 32 mm. El 15% (3/20) de las cabezas chicas (22 y 28 mm) y el 1% (1/90) de las grandes se luxaron (p = 0,0027). No se luxó ninguna cabeza de 36 mm. Las comorbilidades neurológicas más frecuentes fueron depresión, Parkinson y Alzheimer.
Conclusiones: Las cabezas de pequeño diámetro junto con el mal posicionamiento de la prótesis y las enfermedades neurocognitivas se asocian a una inestabilidad mayor. El uso de cabezas de 36 mm y la correcta orientación de los componentes son suficientes para asegurar la estabilidad.

Published: October 2022

Abstract
In the present study, a comparison has been conducted to investigate the efficiency of using the near-surface mounted steel bars technique for strengthening and repairing the damaged reinforced concrete corbels. Three configurations for installing the steel bars have been considered; horizontal, diagonal, and combined. Results revealed that is better to use this technique within the early stages of loading. Moreover, results proved that the strengthening by the diagonal scheme yielded a better response in terms of cracking and failure loads with values of 166 and 95% relative to the control specimen. Also, it is found that for damage of 45%, the horizontal arrangement yielded the highest failure load of 99% whereas for damage of 65%, the diagonal system yielded the optimum value of 50% relative to the control specimen.
Цифровые следы населения как источник данных о миграционных потоках в российской Арктике
Authors: Смирнов Андрей Владимирович 
Published: October 2022

Благодаря цифровизации экономики и общественной жизни расширяются возможности изучения населения с использованием цифровых следов – информации, которая накапливается в цифровой среде. В статье с помощью цифровых следов исследуется миграция населения российской Арктики – огромного макрорегиона, который на протяжении последних десятилетий испытывает значительный отток населения. Обобщен опыт применения цифровых следов в демографических исследованиях, названы их преимущества и ограничения. Для изучения населения российской Арктики использовали данные нескольких цифровых платформ. Анализ профилей пользователей социальной сети «ВКонтакте» позволил изучить миграционное движение, а данные сервиса по продаже билетов Туту.ру дали сведения об авиационных и железнодорожных перемещениях. С применением методов сетевого анализа изучены миграционные и транспортные потоки в российской Арктике на муниципальном уровне, выявлены хабы и кластеры в сетях перемещений. Определены особенности миграционных и транспортных сетей Арктики: низкая плотность, большие расстояния между узлами, высокая относительная подвижность при малом числе перемещений в абсолютном выражении, высокий удельный вес хабов в миграционном обмене. Миграционные потоки классифицированы по направлениям перемещений и типам муниципальных образований. Показано, что связность арктических территорий остается низкой, а положительный миграционный баланс имеют в основном региональные столицы, либо города за пределами Арктики. Полученные результаты позволят улучшить понимание миграционных процессов на Севере и в Арктике, повысить качество демографических прогнозов благодаря более точному моделированию миграционных потоков.

Application of Dual ESP Completion with Remote Monitoring in Offshore Wells Having Variable Flow Conditions
Authors: Prabhu Karthick , Tirawadekar Digambar , Gorde Nilesh , Vasilev Sergei 
Published: October 2022

Abstract
This paper illustrates the benefits of Dual ESP Dual Ytool Systems in Offshore wells where rig intervention costs are high & workover times are huge. It explains how such a completion model along with a Remote Monitoring system can considerably extend the production during the lifetime of a well where a gradual decline in productivity index is expected.
Dual ESP Dual Ytool completions are particularly suited for offshore wells where rig deployment takes time, rig costs are high, and the ESP replacement times last several weeks. Western offshore in India is one such field where a number of such completions have been done and proved to be successful.
The completion model consists of 2 Ytool systems along with 2 sets of ESPs’ where 1 system acts as a redundant system. Wide variation in flow rates is observed due to variation in the productivity index of the well, there is a need to select multiple models of pumps that can produce from the same well. Hence, a higher capacity ESP along with a bigger sized profile of Ytool is used for the upper system and a lower capacity ESP along with a lower sized profile of Ytool is used as a lower system.
At any point in time, only 1 ESP system will be in operation. The second set of ESP will act as a backup and will be operated only if the main ESP fails or if the well conditions change. A sensitivity analysis for all cases is performed to check for possible operating conditions during the design stage. Later on, during the operational stage, the performance is further fine-tuned using Novomet Track © (a remote monitoring system) which offers real-time ESP parameters along with features to check the pump operating point using the last recorded well production data.

Abstract
PETRONAS completed Well H16 in BS field, East Malaysia with a Digital Intelligent Artificial Lift (DIAL) – an improvement to the current applied gas lift system in the field for production optimization system. This DIAL installation represents the first ever successful installation of the technology in an Offshore oil well for Dual String production. This paper provides the details of the installation planning, designing stages, operational process, well unloading and production undertaken to achieve this milestone.
DIAL is a unique technology that enhances the efficiency of gas lift production. Downhole monitoring of production parameters informs remote surface-controlled adjustment of gas lift valves. This enables automation of production optimization removing the need for well intervention which will be challenging in high deviation well (more than 60-degree deviation). With remotely operated, non-pressure dependent multi-valve units, the technology removes the challenges normally associated with gas-injected production operation in a dual completion well i.e., gas robbing and multi-pointing.
DIAL introduces a paradigm shift in design, installation and operation of gas lifted wells. This paper will briefly highlight the justifications of this digital technology in comparison with conventional gas lift techniques. It will consider value added from the design stage, through installation operations, to production optimization. Digitization and automation have become the new concepts in managing the operations in order to boost efficiency that reflected in long-term cost savings especially in Operating Expenditure (OPEX).
This paper focusses on a well completed in November 2020, the fourth well to be installed with the DIAL technology across PETRONAS Assets. The authors will provide details of the well strategy, installation process and production phases: system design, pre-job preparations, improvements implementation, run in hole and surface hook-up. The results of well unloading while utilizing the DIAL system to start up the well and lifting the completion brine will be explained in detail in this paper. For each phase, challenges encountered, and lessons learned will be listed together with observed benefits.
Despite the additional operational & planning complications due to COVID-19 restrictions, the well was completed with zero Non-Productive Time (NPT) and Loss Time Injury (LTI). Once brought online, this DIAL-assisted production well can be remotely monitored and controlled ensuring continuous production optimization, part of PETRONAS’ upstream digitization strategic vision.
Cable Deployed ESP -TransCoil- Retrieval
Authors: Mahmoud Akram Mohamed 
Published: October 2022

Abstract
Over the last few years, we were working to find an alternative deployment solution of the Electrical submersible pumps (ESPs) that help to get rid of the drawbacks associated with the conventional ESP systems:
– Rig availability to install / retrieve ESP systems – Prohibitive intervention costs – Unreliable in-well electrical connections
Finally Saudi ARAMCO and Baker Hughes developed the TransCoil rigless-deployed ESP system to address the issues, help operators bring wells on production faster, and lower overall lifting costs to extend the economic life of producing assets. During the project both system design and deployment method were considered to ensure compliance with ARAMCO standards of engineering, operation, and well controls.
The first TransCoil system was installed in December 2016 as a trial well with a pilot plan to operate the system for six months and pull the system to close the trial. This installation was the first to be done globally to prove that the system developed met the statement of requirements. The system installed and operated for 18 months before it was pulled out in operable condition to close the trial in December 2019. This closed the final step in the trial proving that the system can be deployed and retrieved without a rig and met all the success criteria of the TTR.
To complete the pull-out process, it was necessary to find a way to splice the Coiled Tube cable while continued accessing to the power system for testing throughout the pull-out job. This was achieved by inventing a coupling that not only spool-able and testable during pull-out and re-run, but also immune to Hydrogen embrittlement, non-magnetic, can be nitrided for galling, is cheap to work with and has decent strength.
TransCoil ends are hand drilled and coupled together with the splice coupling by a simple procedure which can be safely done on site. The coupling insulation system can withstand 10KV-AC which is sufficient to conduct a 2500VDC megger test on TransCoil after the down-hole coil and remainder of coil on the spool have been coupled together. in addition, resistance and continuity tests can be done at one phase only as the three conductors are connected as one at both ends of the coupling.
Pulling-out process starting from the TransCoil splice preparation then coupling to completely retrieve the whole BHA took approximately 7~8 hours which is a significant operation time saving in comparison with the conventional ESP pull out which takes at least 18 hours.
This paper shares the background of the system development and trial. Details on the deployment background, de-completion events along with the system benefits.
Proposal - Harmonic Mitigation Challenges in Unconventional ESP Applications
Authors: Hussein Abdelrahman Farouk 
Published: October 2022

Abstract
Permian oil producers are facing increasing pressure from electric utilities to reduce power system harmonics, and the consequences for non-compliance can be severe. This paper details the results of a field-scale effort to reduce harmonics for a ChampionX UNBRIDLED® ESP Systems customer in the Permian basin, and how proper application and troubleshooting of harmonic filters exceeded customer and utility goals.
Electric utilities have long understood that variable speed drives (VSDs) are a significant source of harmonic distortion. However, distortion limits generally have not been imposed on oil producers because utilities have not been significantly impacted, until now.
Due to the large number of VSDs currently operating in the Permian basin (predominantly 6- pulse drives), the harmonics problem for utilities has reached a tipping point. In some locations, distortion of the power grid has become so severe that utilities are no longer able to communicate with smart metering devices – such devices are essential for utility billing and loss of communication with even one of these devices is a serious issue. As a result, Permian utilities have begun mandating harmonic distortion limits, as well as setting deadlines to complete harmonic remediation work. Failure to meet the utility mandates can result in severe consequences for oil producers, including disconnection of electric service or heavy penalties.
Survey on the Recent Design and Tuning Approaches for model-free Fuzzy PID/PI Controllers

Published: October 2022

Abstract
There is good experience in applying classical linear proportional, integral and derivative (PID) controllers to industrial plants due to its simple structure and easy tuning property. However, considering the fact that these linear controllers have fixed parameters, the uncertainties and nonlinearities in the controlled system can degrade the control performance. To tackle the mentioned problems in the application of PID controllers, one of the ways is to incorporate fuzzy logic systems (FLSs) into the PIDs and fine-adjust them. Like the PID controllers, one of the advantages of the FLS-based PID controllers is that they do not require a system mathematical model for control problems, thus these controllers have shown to be a viable control solution for various complicated nonlinear systems. This study presents a survey of development and analysis of model-free PIDs incorporated with FLSs. We focus especially on the widely used fuzzy gain scheduling PID (FGPID) and fuzzy PID (FPID) controllers which are two important combinations of the FLSs and PID controllers. In this study, different structures of FGPID and FPID controllers in which type-1 FLS (T1FLS), interval type-2 FLS (IT2FLS), and general type-2 FLS (GT2FLS) are used as the inference realization part, have also been reviewed. Moreover, the tuning methods of FGPID and FPID controllers’ parameters and their closed-loop stability problems are discussed.
