ABSTRACT

Introduction
Coronavirus disease (COVID-19) is a pandemic of international concern that has caused significant physical and psychological health challenges to healthcare workers worldwide. This study aimed to assess and evaluate the psychological responses of healthcare workers who provided hands-on care for patients with COVID-19 at King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, as it was converted to a dedicated COVID-19 hospital during the pandemic.

Methods
This study used a descriptive cross-sectional design to recruit 500 participants at KFMC between April 10 and May 5, 2020. This study used the 21-item Depression, Anxiety, and Stress Scale (DASS-21) to assess the psychological responses among the study participants.

Results
The findings of this study showed that of 500 respondents, 304 (60.9%) reported having depressive symptoms, 281 (56.3%), 318 (63.3%) having stress and anxiety symptoms. Moreover, 250 participants (50%) who lived with their families reported severe stress and anxiety. However, the results of our study indicated that healthcare workers were committed to providing care to COVID-19 patients.

Conclusions
Depression, anxiety, and stress symptoms were highly prevalent among healthcare workers at KFMC. Therefore, there is an urgent need for psychological interventions to identify healthcare workers with heavy psychological burdens.

Authors: Калинина Екатерина Евгеньевна 
Published: August 2021

Статья посвящена вопросам изучения цветообозначений в чувашском и китайском языках. Цель работы - рассмотреть и систематизировать накопленный в изучении чувашских и китайских цветообозначений опыт. Основой для исследования послужили научные работы по данной теме. Выявлено, что сохраняется устойчивый интерес лингвистов к изучению цвета в самых различных аспектах и направлениях.Актуальность исследования определяется пристальным вниманием к изучению взаимодействия языка, культуры и этноса, где семантическое поле цветообозначения рассматривается как компонент культурного кода. В чувашском языкознании лексика цветообозначений пока не получила должного освещения. Встречаются работы фрагментарного характера, в которых затрагиваются вопросы этноспецифических особенностей символики цвета. Категория цвета в китайском языке широко исследовалась как зарубежными, так и отечественными языковедами.На основе сопоставительного обзора научных работ автор приходит к выводу, что в чувашском и китайском языках исследователи уделяют внимание изучению семантических особенностей слов-цветообозначений, их употреблению в художественных произведениях, анализу в аспекте языковой картины мира, в частности на примере фразеологических и паремиологических единиц. Предпочтение отдается сопоставительным исследованиям цветообозначений в основном с русским и английским языками.
This article is devoted to the color designations in the Chuvash and Chinese languages. The purpose of the work is to consider and systematize the accumulated experience in the study of the Chuvash and Chinese color designations. The study is based on the research works devoted to the subject under consideration. It was revealed that linguists are still interested in the study of color in various aspects and focus areas .The relevance of the work is determined by a very close attention to the study of the interaction of language, culture and ethnicity, which semantic field of color designation is considered as a component of the cultural code. In Chuvash linguistics , the vocabulary of color designations has not been studied properly yet.. There are some works of a fragmentary nature, in which the issues of ethnic specific features of color symbolism are raised. However, the color category in the Chinese language has been widely studied by both foreign and domestic linguists.Based on the comparative review of scientific works, the author comes to the conclusion that in the Chuvash and Chinese languages, researchers pay attention to the study of the semantic features of words of color designations, their use in literary works, analysis in the aspect of the world linguistic picture, in particular, exemplified by phraseological and paremiological units. The preference is given to comparative studies of color designations mainly in the Russian and English languages.
HaloSat Observation of the Virgo Intracluster Medium
Authors: Hewitt Nathan H. , Kaaret Philip , Fuller Chase A. 
Published: August 2021

Abstract
Contained within a galaxy cluster, the Intracluster Medium is comprised of hot, X-ray emitting material between member galaxies. The nearest (∼16.1 Mpc) large galaxy cluster is Virgo. Virgo covers an approximately 12° diameter field, making it challenging to observe in its entirety. The HaloSat satellite utilized a 7° radius field of view to obtain the first full cluster observations since 1994. We then fit the cluster spectra with a plasma emission model of fixed metallicity. Our best fit temperature is kT = 1.39 ± 0.11 keV. We report a cluster luminosity of 5.8 ± 0.7 × 1043 erg s−1 and an emission measure of 5.8 ± 0.6 × 1066 cm−3.
Corrosion Evaluation in Dual Completions Using a Multifrequency Electromagnetic Tool
Authors: Dai Junwen , Fouda Ahmed Elsayed 
Published: August 2021

Abstract
Early detection of corrosion in well casings is of great importance to oil and gas well management. A typical well completion includes a production tubing inside a number of nested casings, which provide necessary well integrity and environmental protections. A multifrequency electromagnetic pipe inspection tool with multiple transmitter and receiver arrays was designed to accurately estimate the individual wall thicknesses of up to five nested pipes. The tool uses an axis-symmetric forward model to invert for wall thicknesses, among other pipe parameters. However, in cases where production occurs from two or more segregated zones, the well is generally equipped with more than one production tubing, which breaks the axial symmetry. In this paper, we show how the tool can further be employed to inspect the integrity of non-nested tubulars, such as dual completions. The performance of the tool is demonstrated using a full-scale yard mockup with known defects.
A data-processing workflow, including multizone calibration and model-based inversion, is proposed to estimate the tubulars electrical conductivity, magnetic permeability, wall thickness, and eccentricity. An in-situ, multizone calibration method is applied to remove adjacent tubings influence, thus enabling accurate estimation of the thickness of outer casings without having to pull out the production tubing.
In order to demonstrate the capabilities of the tool in wells with dual completions, a log was run in a 150 ft-long yard mockup with two strings of 2⅞ inch. tubing, two outer casing strings, and four different man-made defects on the casings. The tool is logged inside each of the tubing strings, and the two logs are inverted for the thickness and eccentricity of the tubing as well as the thickness of outer casings.
Results from the yard test reveal that when the tool is logged in one tubing, it can accurately detect various kinds of defects on outer casings, even in the presence of a second tubing. The interference from the second tubing is shown to be minimal due to the employed calibration algorithm. A high degree of consistency is seen between the logs run in each tubing string. This suggests that if the goal is solely to monitor corrosion in the outer casings, it suffices to run the tool in only one of the tubing strings, further cutting nonproductive time.
The techniques presented here enable pipe integrity monitoring without pulling the production tubings; tubings, therefore, minimizing inspection time and cost. The information provided by this tool can significantly improve the efficiency of well intervention operations, especially in areas with high corrosion rates.
On the Subsea Production System Availability with Resident Drones. A Reliability, Availability, Maintenability RAM Analysis
Authors: Mattioli Matteo , Di Padova Annamaria 
Published: August 2021

Abstract
The challenge in the Oil&Gas industry to remain competitive in a low oil price whilst dealing with minimization of operational risk and uptime asset maximization is leading offshore Companies to evolve thought proactive and predictive maintenance approaches. In the event of unplanned intervention due to anomalies or warning messages at the dispatching center, the decision on the size of the support vessel and its utilization for straordinary maintenance could be time consuming with potential high cost impact, also due to loss of production. Even the new generation of remote condition and monitoring systems, which allow to improve the capability of operators for early warnings and surveillance, provide a reliable solution for emergencies. In this context, resident subsea drones enable on-demand inspection whilst eliminating the need for support vessel and allow operator to manage the risk in continued operations also for dangerous areas restricted to human access.
A case study relevant to a new subsea field development have been conducted. Distinctive Reliability, Availability and Maintainability (RAM) analyses have been performed with the aim to get insight on the subsea production system availability considering a resident drone and to demonstrate how the so called "stategic maintainability" can be applied successfully in the decision-making process while reducing the OPEX. The former related to conventional IMR (Inspection, Maintenance & Repair) based on Condition Based and RBI, Risk Based Inspection approach, the latter related to strategic maintenability with resident drones. The application of such analysis required a multi-disciplinary approach together with the possibility of processing historical data in operating conditions. Historical data sources (e.g. OREDA dataset) were collected to obtain failure rates and active repair times typical of subsea equipment. Direct experience gained in over forty years of inspection and maintenance activities together with recent developments on subsea resident robotics allow the understanding of real internvention timing.
Results show that resident subsea drones applied for early inspection and light intervention are confirmed timely and costless solution respect to conventional IMR services. They represent the first aid for environmental surveillance and subsea inspection in case of emergency and provide a relevant saving of subsea production un-availability.
The economic value emerged from the presented case study represents a step change for OPEX optimization and motivates Best-in-Class Operators to get an insight case-by-case for both green and aging fields.
Accelerated First Oil With Integrated Execution Model, Digital FEED Platform And Product Standardization

Published: August 2021

Abstract
This paper illustrates how a subsea integrated ("SURF – Subsea Umbilicals Risers Flowlines" and "SPS – Subsea Production systems") execution model can be significantly improved in further reducing the time to first oil. It illustrates the use of digital platforms for FEEDs (Front End Engineering and Design) and Configure to Order (CTO) product designs to provide further schedule improvements resulting in an enhanced execution model. The time to first oil is considerably improved by cruising through the Front-End design gates using digital FEED platforms. CTO designs enable a project to reach the manufacturing gate faster by reducing detailed engineering effort significantly and in some cases eliminating it. The paper provides an introduction to the conventional execution model (Split SURF and SPS scopes), the integrated execution model (combined SURF and SPS scopes) and the enhanced integrated execution model (using digital FEED platform and CTO products). A comparison has been made on project delivery schedules between the three models illustrating the schedule savings through use of digital FEED platforms and CTO designs. It concludes that digitalization of FEEDs and standardization of product configurations create value for the operators in context of faster return on investment. Digital FEEDs are a new concept and still in its infancy. CTO design is a known concept; however, in context of a subsea project, how it may improve schedule delivery is not well established. These factors are truly an enhancement to the integrated execution approach and the additional value gets delivered to the end customer by further accelerating the time to first oil.

Abstract
To meet and sustain the increasing energy needs of a growing world economy, exploration for oil and gas will be directed to increasingly extended reaches, complex profiles and hostile environments. Progress in harnessing high-pressure high-temperature (HPHT) sour fields (environments containing hydrogen sulphide gas or H2S) and reducing the cost of extracting and refining will be highly leveraged by political and macroeconomic considerations. Motivated to harness the complex tight carbonate reservoirs in offshore Arabian Gulf, a major National Oil Company (NOC) in UAE and its partners embarked on an extensive and ambitious project to produce oil and gas from offshore artificial islands. To capture the full economic benefits of this project, operators are expected to drill farther and farther into one of the world's longest deep-water reservoirs (wells with laterals lengths beyond 40,000 feet). It has also taken them a decade of innovative technology development to be able to successfully harness these challenging deep-water assets. Among the technologies developed, one of the essential tools, a dissolvable plugged nozzle assembly (DPNA) with its ability to withstand higher pressures encountered at larger depths, while maintaining its mechanical integrity for extended times in heavy brines, enabling longer sweeps, thus service deeper wells was needed by operators. Recognizing this grand challenge, we designed and developed a pressure balanced HPHT DPN (PB-HPHT DPN) with erosion resistant Ni alloy jointly developed with a major Japanese steel and Ni alloy producer and anion-insensitive nano-BMGC plug developed by us. The PB-HPHT DPN has the following groundbreaking properties: (i) It can sustain pressures of up to 5,500 psi differential pressure (ΔP) for 48 hours when pressurized from inner diameter (ID) to outer diameter (OD), and can subsequently breakthrough on 500 psi DP pressure reversal (OD to ID) within 14 days from the start of the operations; (ii) It can be deployed in environments encompassing up-to 43% Bromide or up-to 21% Chloride brines and reaching temperatures as high as 250° F. Additionally, verification and validation (V&V) is supported by flow testing combined with Computational Fluid Dynamics (CFD). The design of the PB HPHT-DPN allows a fluid flow of up-to 0.6 bpm across the nozzle without experiencing a differential pressure increase of &gt;2400 psi in a 4 mm DPN. In summary, the PB-HPHT DPN is a revolutionary device that will allow operators to efficiently produce oil and gas in extremely hostile environments.

Abstract
Gas developments are required to facilitate energy transition from carbon intensive energy to a sustainable balance of green and blue energy. The next decade will focus on exploiting gas fields globally to support this. A significant number of these fields are located in deepwater and /or are long distances from existing gas processing / LNG plants.
Transporting large volumes of gas from remote gas fields over longer distances and in deeper waters remains technologically and economically challenging. Conventional and near-term development options include subsea compression, floating vessels with topside compression and pipeline tie-back to shore, or floating liquefied natural gas vessels.
This paper and study are supported by The Oil & Gas Technology Centre (OGTC) and UK Oil and Gas Authority. It examines development options for a 200 km long 1700 m water depth tie back using integrated production modeling linked to power demands, along with installed steel tonnages. The Scope 1 and 2 emissions per unit of gas produced are analysed via a life cycle assessment using ISO 14044 as guidance for a long-distance gas tieback to the point of sale (inclusive of processing to sales specification). The major power intensive equipment used to develop these fields will be presented showing their proportion of the power consumption compared with the total; these include compression either onshore, offshore or subsea as well as the efficiency of the power generation devices in these environments. The paper will highlight the economics of each option and how varying the carbon price changes the commercial position of each option. The paper will show that by understanding what drives emissions, and how emissions relate to the amount of gas produced, that concept selection can drive upwards of 50% reduction in life cycle carbon emissions whilst improving project economic performance.
This paper examines multiple innovative technologies, providing technology readiness of new concepts based on the benchmarked study focusing both economic and carbon emission aspects. Finally, the paper will show that better economic outcomes with the decarbonisation of gas gathering systems is technically possible and can be deployed subsea to help meet the energy transition and allow the development of remote and deeper gas fields.
