ГИДРОХИМИЧЕСКАЯ ИЗМЕНЧИВОСТЬ РЕКИ АНГАРА ПРИ СОЗДАНИИ БОГУЧАНСКОГО ВОДОХРАНИЛИЩА (РОССИЯ)
Authors: Полетаева Вера Игоревна 
Published: October 2022

Актуальность исследования обусловлена необходимостью контроля за гидрохимическими параметрами крупной пресной водной экосистемы для объективной оценки трансформации водоема, находящегося под антропогенным воздействием. Цель: изучить пространственно-временную динамику концентраций основных ионов в водах р. Ангары и Богучанском водохранилище. Объекты: р. Ангара до ее зарегулирования плотиной Богучанской ГЭС (2007 г.) и Богучанское водохранилище в период его заполнения (2013, 2014 гг.) и стабилизации уровня (2015, 2017 гг.). Методы. Химический анализ образцов воды проведен в Центре коллективного пользования «Изотопно-геохимических исследований» ИГХ СО РАН (г. Иркутск, Россия). Измерение концентрации Na+ и К+ в воде выполнено эмиссионным пламенно-фотометрическим методом, Са2+ и Мg2+ – методом атомно-абсорбционной спектрометрии, SO42– – турбидиметрическим методом, Cl– – меркуриметрическим методом, HCO3– – титриметрическим методом. Результаты. В пространственно-временном аспекте изучены концентрации катионов (Ca2+, Mg2+, Na+, K+) и анионов (HCO3–, SO42–, Cl–). Результаты исследования показали близкие значение TDS в воде мониторинговых станций р. Ангары (140,7–154,6 мг/л) и Богучанского водохранилища (139,1-172,3 мг/л). Однако увеличение уровня водоема приводит к изменению в соотношении концентраций главных ионов. По сравнению с р. Ангарой, в начальный период функционирования Богучанского водохранилища в воде увеличиваются концентрации SO42–, Cl–, Na+, Mg2+, уменьшаются концентрации HCO3– и Ca2+. Ионный состав вод Богучанского водохранилища определяется прежде всего вкладом из области, расположенной выше по потоку (сток из Усть-Илимского водохранилища). К антропогенным факторам относятся сточные воды и само создание водохранилища, оказывающие влияние на гидрохимию главных ионов.

Актуальность работы определяется возрастающим спросом на энергию, особенно на экологически чистую. В настоящее время большое внимание уделяется исследованию и совершенствованию возобновляемых энергоисточников. Производство электроэнергии с использованием фотоэлектростанций весьма перспективно в районах с высокой инсоляцией, где централизованные энергетические системы недоступны, или в случае, когда доступная электроэнергия обходится дорого. Однако высокая стоимость оборудования фотоэлектростанций ограничивает возможности их широкого применения. Одним из способов снизить стоимость фотоэлектрической установки является аккумулирование электрической энергии не только в электрохимических батареях, но и в виде нагретой воды в менее дорогих водонагревательных установках, что позволит уменьшить стоимость фотоэлектрической установки за счет уменьшения ёмкости батарей при одновременном обеспечении потребителя горячей водой. Одной из актуальных задач является разработка алгоритмов управления фотоэлектростанций с гибридной электрохимической и электротепловой системой аккумулирования фотоэлектричества. Цель: разработка интеллектуального алгоритма управления энергетическим балансом автономной фотоэлектростанции с электрохимическим и электротермическим аккумулированием фотоэлектричества. Методы: аналитические методы исследования фотоэлектрических станций с агрегатным способом аккумулирования солнечной энергии: в электрохимических и электротермических батареях, методы компьютерного моделирования, метод сравнений с предыдущими научными исследованиями. Результаты. Разработана структура системы управления энергетическим балансом фотоэлектростанции с электрохимическим и электротепловым аккумулированием фотоэлектричества; предложен алгоритм функционирования системы управления с использованием МРРТ технологий; структура и алгоритм функционирования протестированы на примере оптимизации энергетического баланса социального объекта на территории Ирака путём моделирования в программном комплексе Matlab.

Актуальность работы обусловлена необходимостью совершенствования методов мониторинга характеристик подземных вод и их изменений в сейсмоактивных районах Республики Алтай. Подземные воды являются индикатором сейсмических процессов и реагируют на изменения напряженно-деформированного состояния горных пород в зонах очагов предстоящих тектонических землетрясений. Целью: выявление краткосрочных изменений содержания гелия и обобщенных гидрогеохимических показателей в высоко динамичных объектах мониторинга подземных вод Республики Алтай для поиска предвестников сильных сейсмических событий. Методы. В основу работы положены результаты ежесуточного мониторинга подземных вод на территории Республики Алтай, который осуществлялся в январе–феврале 2021 г. на пунктах наблюдения за температурным режимами и качественным составом подземных вод – скважина и колонка – Горно-Алтайского отделения «Сибирского регионального центра Государственного мониторинга состояния недр». Результаты. Впервые на территории Горного Алтая было проведено изучение динамики гидрогеохимических характеристик и содержания гелия в подземных водах и показаны кратковременные (1–3 сутки) изменения данных характеристик в связи с землетрясениями. Для проведения данных исследований были взяты две точки мониторинга подземных вод, расположенные в г. Горно-Алтайске (колонка) и с. Старый Бельтир (скважина), удаленные друг от друга на расстояние более 200 км. Данные точки мониторинга были выбраны в связи с тем, что там было зафиксировано существенное изменение характеристик подземных вод при подготовке и протекании сейсмических событий в регионе. В работе дана характеристика сейсмического режима Алтае-Саянского региона в период мониторинга. Для выявления динамики содержания гелия и гидрогеохимических характеристик подземных вод нами было начато изучение этих характеристик в период 14.01–23.02.2021 г. Показано, что точка мониторинга Старый Белтир, расположенная в разломной зоне вблизи эпицентральной зоны Чуйского землетрясения (2003 г.) характеризуется высокой чувствительностью изменения не только гидрогеохимических характеристик подземных вод, но и высоким реагированием динамики содержания гелия на землетрясения. В результате исследований было выявлено, что Монгольское землетрясение (2021 г.) не оказало влияния на гидрогеохимический состав изучаемых пунктов мониторинга, расположенных на территории Горного Алтая, в то же время в представленных пунктах мониторинга подземных вод отражаются ближайшие к ним сейсмические события. Выбранные пункты мониторинга в ряде случаев не перекрывают друг друга и реагируют в основном на ближайшие к ним землетрясения, в том числе и на слабые. Наиболее динамичная реакция на землетрясения отмечена у гелия, pH, Eh, температуры.

Published: October 2022

This research aims to find effects of teachers’ stress on teacher well-being in teachers of inclusive elementary schools. This is a quantitative research with one predictor linear regression analysis. Samples in this research were 117 inclusive elementary schools collected using the accidental sampling. Variable of teachers’ stress was measured using Teacher Stress Inventory (TSI) developed by Collie and variable of teacher well-being was measured using Teacher Well-Being Scale (TWBS) developed by Firman & Fastenau. The research results showed significance value (ρ) OG 0.000, which was smaller than 0.5, and it was found that F-count was 29.795 and F-table was 3.92. It meant that teachers’ stress provided significant effects on teacher well-being in teachers of inclusive elementary schools. This study concluded that if teachers experience high levels of stress, it will reduce their level of teacher well-being. In addition, it was found that R-square was 0.206, which meant that teachers’ stress provided effect of 20.6% on teacher well-being in teachers of inclusive elementary schools.

Published: October 2022

ABSTRACT
We analyzed nine benthic foraminiferal species from the Açu Reef belonging to the orders Rotaliida and Miliolida, symbiont-bearing (Rotaliida: Amphistegina gibbosa, Heterostegina depressa; Miliolida: Peneroplis carinatus, Archaias angulatus, Amphisorus hemprichii, and Archaias compressus) and symbiont-barren (Rotaliida: Buccella peruviana, Pseudononion atlanticum; Miliolida: Quinqueloculina lamarckiana). Stable isotopes measured on individual tests display a large intraspecific variability (δ18O: ∼1–1.5‰; δ13C: ∼2–3.5‰) that is not associated with site location, sampling season, or water depth. Positive correlation between δ13C and δ18O values is significant in three of the species (A. gibbosa, B. peruviana, and Q. lamarckiana), with a regression slope similar to other marine calcifiers (∼2‰ δ13C/‰ δ18O), perhaps related to the carbonate chemistry of the calcifying fluid. With the exception of A. gibbosa, offsets from δ18O equilibrium, when distinct, tend to be positive. Offsets from δ13C of ΣCO2 of sea water are negative for two of the rotaliids (A. gibbosa and H. depressa) and positive for three of the miliolids (P. carinatus, A. angulatus, A. hemprichii), with non-symbiont-bearing species of both orders being close to the sea water values (∼ 1.3–2‰). These δ13C differences are consistent with calcification pathways of rotaliids versus miliolids, with the former drawing carbon from an internal pool and the latter from ambient seawater. Our study contributes a large data set that illustrates the importance of vital and abiotic effects on the stable isotopic composition of large benthic foraminifera in a tropical continental shelf, limiting their applicability as paleoenvironmental tracers.
Probabilistic Approach Guides Field Development Plan in Niger Delta

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 207146, “Conceptual Field Development Plan for X Field,” by Khadijah Ibrahim, SPE, Petrus Nzerem, and Ayuba Salihu, SPE, Nile University of Nigeria, et al. The paper has not been peer reviewed.

_
The development plan of a new oil field discovered in a remote offshore environment in the Niger Delta was evaluated. Because the oil in place was uncertain, a probabilistic approach was used to estimate the stock-tank oil originally in place (STOOIP) using low, base, and high cases. The base model is recommended for further implementation. The quantity of oil produced is estimated at 15,000 STB/D, which will require a separator that has the capacity of holding a liquid rate of approximately 20,000 STB/D. The authors find that this developmental plan is cost-effective.

Introduction
Field X is offshore Nigeria in water depths of 330 ft. The field has an uncertain oil in place, with a possibility of low, base, and high cases. The field reservoir information is available from the exploration and seismic well data provided. The field size (i.e., STOOIP) is estimated at 95 million (low), 145 million (base), and 300 million (high) STB, with an irreducible water saturation of 22%. The reservoir depth is 7,400 ft true vertical depth subsea (TVDSS), with a net pay thickness of 45 ft. The aquifer supporting the reservoir has a strength of 9, with a permeability of 200 md and a porosity of 18%. Generally, the reservoir has permeability and compressibility of the rock formation obtained from the log results of 250 md and 3.5×10–6 psi–1. The reservoir pressure is measured to be 3,400 psia.
The field development plan will incorporate production forecasts from the target date of first production, 1 January 2023, through 1 January 2038, for a 15-year field life. The complete paper presents the field development strategies and economic analysis of different well models to evaluate the most-efficient modeling profile for the new field.

Methodology
Well-Modeling Profile and Performance Analysis.
It is assumed that the field will be produced using a platform with a wellhead reference depth of 20 ft above the rotary kelly bushing. The well is assumed to be a vertical well with no deviation. The skin value is estimated to be 1, thereby having a slight effect on the productivity index. Pressure/volume/temperature (PVT) data were available for the oil in place. Using commercial software, the fluid parameters for bubblepoint pressure, oil volume factor, and oil viscosity were matched in the PVT analysis at a reservoir temperature of 170°F and a pressure of 3,400 psia. The measurements of formation volume factor, gas/oil ratio, and oil viscosity at this pressure were used to provide a single match point for the generation of PVT data.
Legacy Gulf of Mexico Oil and Gas Facilities Hold Promise for Role in Blue Economy

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 31940, “Repurposing Gulf of Mexico Oil and Gas Facilities for the Blue Economy,” by Roy Robinson, SPE, Excipio Energy; Georg Englemann, Diamond Infrastructure Development; and Kent Saterlee, Gulf Offshore Research Institute. The paper has not been peer reviewed.

_
This synopsis presents portions of the results of a Department of Energy (DOE) study of the potential for repurposing legacy oil and gas facilities in the Gulf of Mexico (GOM) for uses in a blue economy. The study was limited and was designed to summarize practical options for repurposing. The conclusions list those areas in which further modeling or studies are warranted, with the objective of building an integrated modeling tool to assist companies, government agencies, and nongovernmental organizations in assessing benefits and risks of repurposing facilities.

Scope Limits of the Repurposing Study
The term “blue economy” is defined by the World Bank as a sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean ecosystem health. The study upon which the paper is based was confined to the repurposing of oil and gas facilities in the GOM, specifically platforms, wells, pipelines, and rights of way. Producing, idle, and abandoned assets were considered. The objective was to explore how leveraging these existing facilities can reduce the carbon load of offshore oil and gas production, speed the energy transition by tapping the tremendous energy potential of the ocean, reduce US dependence on imported seafood and minerals, and create secure long-term employment along the Gulf Coast.

Energy Resource Potential and Definition
In 2020, the US National Renewable Energy Laboratory (NREL), at the request of the Bureau of Ocean Energy Management (BOEM), produced a report on the renewable energy potential of the GOM. NREL divides resource assessments into gross and technical potential. “Gross” is intended to be the total available resource. “Technical” is based on NREL’s assessment of how much of the resource could be captured economically using proven technology. Details are included in the complete paper because the NREL/BOEM report has caused some questions to be raised by those reviewing the DOE study. The authors’ commentary on this report is detailed in the complete paper.
Low-Carbon and High-Efficient Heat Provision by High-Temperature Heat Pumps with Subsequent Steam Compression
Authors: Diezinger Stefan , Huettl Christian , Schaefer Jochen , Paul Christian , Lienau Arne 
Published: October 2022

Abstract
Heat is the world's largest energy end use, accounting for almost half of global final energy consumption in 2021 (IEA, 2021). Heat is utilized in various applications across a broad range of industries, including refining, chemicals, pulp and paper, textile manufacturing, district heating systems, buildings, etc.
Large scale, low-temperature heat pumps are a well-established technology and are currently able to achieve temperature levels of up to 100°C. In recent years, demonstration projects involving Siemens Energy and other original equipment manufacturers (OEMs) have shown that temperatures up to 150°C and 4 bar are within reach using modern high-temperature heat pumps. Further progress has been made to extend this range up to 270°C and pressure levels up to 60 barA using subsequent steam compression. Such configurations recently became bid ready in the marketplace.
This paper provides an underlying description of modern electric heat pump technology and will show how it can be used as a low-carbon alternative to traditional heating methods, such as oil- or gas-fired boilers. Several real-world applications will be presented, including one concept at a large integrated chemical complex in Europe, where a high-temperature heat pump and steam compressor are combined to achieve a temperature of 240°C at 19 barA with a coefficient of performance (COP) of 3.
Supplier Performance Management for Successful Project Execution and Adding Value to Supply Chain
Authors: Kashif Muhammad , Al-Rawas Dalya 
Published: October 2022

Abstract
The Supplier Performance Management (SPM) aims to increase compliance and profitability by preventing risks of cost and schedule overruns due to failures in supplier performance. The excellence in Supply Chain is not possible without implementing a robust SPM. Once SPM is in place suppliers' performances can be analysed, tracked, and improved.
This paper provides complete supplier performance measurement criteria for the project execution stage (a key stage of SPM, success of project depends on it). The paper can be considered a base document for supplier performance management in the project execution stage. Supplier performance once implemented in the project execution stage then can be extended to other stages as pre-award and to vendors for material supply.
Supplier performance comprises four processes: measuring supplier performance; analysing performance data; communicating and engaging with the suppliers; and working together to continuously improve.
The supplier evaluation process starts with initiation of performance score event with typical performance measurement elements such as Quality of Work/Services, Execution: Work Performance, and Health, Safety & Environment (HSE). The elements can have different weightages. The evaluation is done by the contract administrator involved with the contractor during the execution stage. The typical evaluation frequency can be annual, or bi-annual but more frequent evaluations can be done depending on nature or critically of project.
This paper highlights the importance of segmentation of suppliers to optimize supplier performance efforts and increase the prospect of value addition. Based on the Kraljic Matrix analysis, suppliers to be divided into at least four segments - Strategic, Single Sourced/OEMs, Managed, and Low level.
Also, the paper proposes the Strategic Supplier Performance Management (SSPM) process for strategic supplier segment to add quick value to supply chain. SSPM in fact is the application of the Pareto Principle and works by constituting a task force of all concerned stakeholders to formulate smart KPIs to add value.
People Development - Holistic Approach to Leadership & Development

Abstract
In 2020 the Australian Institute of Management conducted a Leadership Survey and the "most important finding was that poor leadership is a major contributing factor to employee attrition."
"75.55 % of respondents stated that they had left an organisation in their last three roles because of the leadership team, their direct manager, or a combination of both. Nearly half (42.32%) had left more than one of their previous roles."
We can clearly see that "poor leadership will simply not be tolerated by employees, and this is a rising trend."
VOC Recovery System for Crude Oil Tanker Loading
Authors: Kamel Merhane , Al Shehhi Khalid 
Published: October 2022

Abstract
During offshore and onshore loading of crude oil tankers, huge volumes of valuable Volatile Organic Compounds (VOC) are emitted to the atmosphere maybe up to 330 ton per Very Large Crude Oil Carrier (VLCC). When these emissions are liquified, they will be equal to hundreds of barrels of oil. They are a substantial source of financial loss and destructive environmental impact. The objective of this paper is to introduce a Vapor Recovery System concept which can limit & recover the emissions of VOC up to 90% at the Fujairah Terminal.
All loading and unloading of oil on offshore, on Floating Storage Offloading Unit (FSOs) and Floating Production Storage Offloading (FPSOs), on onshore storage tanks and terminals, and on shuttle tankers contribute to significant emissions of VOCs. It is possible to install Vapor Recovery Unit (VRU) on each of these applications to capture and recover VOCs. There are two generic approaches to VOC recovery, known as ‘Active’ and ‘Passive’ VOC recovery technology. The Active Vapor Recovery Unit VRU systems typically include a compression step followed by condensation, absorption and/or adsorption. The Passive VRU systems use vapor-balanced loading/unloading with VOC as blanket gas for storage vessels.
The VOCs are a combination of Methane and Non-Methane components which evaporate from crude oil and are typically vented into the atmosphere during routine ship loading activities, causing emissions of harmful vapor to the environment. These vapors also represent a fire/explosion hazard. The methodology will be to apply a new concept to limit and recover the VOC emissions during loading of crude oil tankers alongside a Single Point Mooring (SPM). The VOC recovery technology is a unique combination of a modern offshore Supply Vessel (OSV) which considers both hydrocarbon recovery as well as power generation.
