Published: March 2023

Imigração é um assunto que tem recebido atenção nos últimos anos, cerca de 774.000 imigrantes foram registrados até o ano de 2018, e dentre as nacionalidades mais frequentes está a haitiana. O objetivo deste estudo foi relatar o aperfeiçoamento da atenção odontológica ao paciente haitiano e melhoria no acesso à Unidade de Básica de Saúde por meio de tradução dos termos odontológicos. Inicialmente foi realizado o reconhecimento territorial da área de abrangência da UBS, onde constatou-se que a Unidade Básica de Saúde assistia 470 imigrantes haitianos. A equipe elaborou e distribuiu a população cartilhas e panfletos para que a população em geral conhecesse sobre a cultura haitiana, simultaneamente realizou-se a tradução fichas de agendamento, anamnese, placas de identificação do consultório e de normas de segurança além de uma ficha de auto percepção do paciente sobre sua saúde bucal, sendo que estas foram aplicadas durante os atendimentos clínicos. Após seis meses foi realizado um levantamento com imigrantes e profissionais de saúde e constatou-se que à partir desta experiência houve redução significativa da barreira de comunicação, e consequentemente houve melhora no acolhimento dos pacientes. O aperfeiçoamento dos serviços e a adequação dos servidores foi de extrema importância para melhorar o contato entre profissionais da saúde e imigrantes, além da formação interprofissional, e fortalecimento da integração ensino-serviço-comunidade.

Este texto é uma das conferências que integrou  a programação do "II Colóquio Internacional Migração, Saúde e Direitos Humanos: caminhos teóricos, metodológicos e políticos", realizado em Brasília, em outubro de 2019, no contexto projeto de migração e direitos humanos que constitui parte de uma cooperação acadêmica Brasil-França, junto a Universidade de Brasília e a Universidade Federal do Rio de Janeiro.  A experiencia da ativista e intelectual, Marguerite Rollinde, permitiu sistematizar em uma forma retrospectiva a discussão de aspectos que tem integrado a pauta da luta pela migração na França nas últimas três décadas. Ela dialoga tanto com as políticas públicas de migração quanto com a força dos movimentos sociais pelos direitos e o reconhecimento não apenas do direito dos imigrantes mas, de expressões essencias que operam na prática do direito como o gênero, a pertença étnica e a diversidade cultural.
Direitos humanos e repercussões à Saúde de Migrantes integrantes do Programa de Estudantes Convênio de Graduação (PEC-G) na Universidade de Brasília
Authors: Rodrigues de Assis Raul , Hoefel Maria da Graça Luderitz , Osório Severo Denise
Published: March 2023

O Programa de Estudantes Convênio de Graduação (PEC-G) foi criado em 1965 e se insere no bojo das cooperações internacionais no campo da educação, sob responsabilidade do Ministério da Educação e do Ministério das Relações Exteriores do Brasil. A Universidade de Brasília recebeu 81 estudantes PEC-G em 2019 e, embora o programa exista há décadas, pouco se sabe sobre as condições de vida e os direitos humanos desses estudantes. Esta pesquisa visa compreender em que medida os direitos humanos dos estudantes originários de países africanos vinculados ao PEC-G da UnB estão sendo contemplados e quais são as possíveis repercussões sobre a saúde desses sujeitos. Constitui uma pesquisa-ação, de abordagem qualitativa, desenvolvida em 2018, por meio da realização de cinco oficinas de fotografia e direitos humanos, com base no método do Projeto Vidas Paralelas (PVP) Migrantes. Os instrumentos de pesquisa adotados foram oficinas, registros audiovisuais/fotográficos, registro de voz e diário de campo. Os dados foram tratados por meio de duas fases de análise, em conformidade com o referido método, o qual inclui a análise de conteúdo. Os resultados sinalizam que os direitos humanos dos estudantes migrantes vinculados ao PEC-G ainda não são plenamente contemplados. Nota-se que as dificuldades de acesso à alimentação, à moradia e à saúde são presentes e afetam expressivamente a vida e a permanência desses estudantes durante sua formação no Brasil. Essa situação gera várias repercussões sobre a saúde e o cotidiano de vida desses sujeitos, especialmente a saúde mental.
Evolución de la cesárea en Colombia y su asociación con la naturaleza jurídica de la institución donde se atiende el parto
Authors: Zuleta-Tobón John Jairo
Published: March 2023

Objetivos: describir la evolución de la frecuencia de la cesárea en Colombia a partir de 1998, tanto global como discriminada según la naturaleza jurídica de las instituciones prestadoras de salud (IPS) donde se atienden los partos, y calcular la magnitud de la asociación entre la naturaleza jurídica de la IPS y la realización de cesáreas entre 2015 y 2017.Materiales y métodos: estudio de corte transversal que describe la frecuencia de partos por cesárea entre los años 1998 y 2020, y un componente analítico para estimar la asociación entre la naturaleza jurídica y la vía del parto entre los años 2015 y 2017, a partir de las bases de registros de nacimientos del Departamento Administrativo Nacional de Estadística (DANE) de Colombia. Se presentan las proporciones de cesárea por año y el incremento en la proporción de cesárea por tipo de institución; como estimador de esta asociación se utilizó la razón de prevalencia.Resultados: en 1998, la proporción de cesárea fue 25,7 %, incrementó hasta 46,4 % en 2015 y descendió a 44,6 % para 2020. A partir de 1998, la proporción de cesárea en las IPS públicas pasó de 26,2 a 42,9 % para el año 2014 y en las privadas de 45,0 a 57,7 % para el año 2013. La razón de prevalencia de la cesárea de las instituciones privadas con respecto a las públicas fue 1,57 (IC 95 %: 1,56-1,57).Conclusiones: después de un periodo largo de incremento sostenido, se está presentando una disminución en la proporción de cesáreas en el país; las IPS públicas incrementaron estos procedimientos en mayor proporción durante la mayor parte del tiempo estudiado y en las IPS privadas se realizan con mayor frecuencia a todos los subgrupos de mujeres. Se deberá evaluar en el futuro, mediante metodologías más robustas, si el descenso en la frecuencia de cesárea es una tendencia real o secular.

Examination of Social Appearance Anxiety through Psychological Theories
Authors: KIZILKAYA Mehtap , ÖZKAYA Ahmet Salim
Published: March 2023

Social appearance anxiety, which is expressed as a type of social anxiety, is defined as the state of tension and anxiety experienced by people when their physical appearance is evaluated by others. In the literature, there are studies examining the factors that increase or decrease social appearance anxiety and the negative effects of social appearance anxiety. However, it is noteworthy that psychological theories are not included in the examination of social appearance anxiety, which is a common problem experienced by almost everyone at certain periods of their lives. Addressing the concept of social appearance anxiety from a theoretical perspective will contribute to the understanding of the concept, better planning of future research, and will also fill the gap in the literature. In this context, in this review study, the concept of social appearance anxiety is explained, and then the concepts related to its analysis in terms of psychological theories are discussed.

COGNITIVE NATURE OF CONVENTIONAL AND LITERARY METAPHOR: COMPARATIVE ANALYSIS
Authors:   Uzbek State University of World Languages, Ashurova D.U.
Published: March 2023

The article is concerned with the cognitive analysis of conventional and literary metaphors, their similar and distinctive features, linguistic and extralinguistic factors determining the specificity of each type. The new findings of the research are: 1. Both types of metaphors have similar cognitive mechanisms including the processes of a) structuring one conceptual domain within the other; b) conceptual integration of the two interconnected conceptual domains; c) modelling the cognitive structure of metaphor on the basis of image representations and propositional schemas; d) activation of associative mechanism of metaphor; e) emerging new conceptual elements; 2. Literary metaphor is different from conventional one in many respects a) it shares many features of the literary discourse such as anthropocentrism, subjectivity, imagery, emotiveness, implicitness, associativity, both textual and non-textual, conceptuality, interpretedness; b) it is consistent with the author’s aesthetic and communicative intentions; c) it is dependent on all types of contexts (linguistic, pragmatic, cognitive, sociocultural); d) represents macro- and megaconcepts of the literary text; f) becomes a significant component of the author’s individual world view; g) assumes the function of conceptual dominant in the literary discourse; i) forms an extensive network of textual and non-textual associations.
Vacuum Expansion and Collapse Inside an Infinite Shell
Authors: Laforet Christopher
Published: March 2023

The FRW model of cosmology assumes a Universe with uniform pressure and density everywhere in space at a given time. But at the largest scales, the Universe has a web-like structure surrounding large voids, violating these assumptions. Furthermore, a given region of spacetime is describable only by a single metric and therefore it cannot be that the Universe is modelled as an FRW perfect fluid since this would be the incorrect description of both the web and the voids. The cosmic web must be described by metrics with non-zero energy-momentum tensors with non-uniform pressure and density describing the matter within it. Therefore, the model of cosmology describing the expansion of the Universe must be a vacuum solution describing the empty spaces in the Universe surrounded by an infinite, massive shell (the surrounding Universe). The internal Schwarzschild metric is that model. The source of the Schwarzschild metric is shown to be at the event horizon, a location/time of infinite density, not at the singularity, as it is currently assumed. The spatial homogeneity of the metric is demonstrated by visualizing the geometry in the extrinsic "Kruskal-Szekeres" coordinates (visualized in 1+2 dimensions). Using the coordinate age of the Universe and transition redshift, this predicts the accelerated expansion, the Hubble diagram fits currently available cosmological data, and it gives a Hubble constant H0 of 71.6km/s/Mpc. The angular term of the metric describes the relativistic kinematic precession effect known as Thomas Precession which can be interpreted as spin about the time dimension.
The Imaginary Universe
Authors: Łukaszyk Szymon
Published: March 2023

Imaginary dimensions in physics require an imaginary set of base Planck units and some negative parameter $c_n$ corresponding to the speed of light in vacuum $c$. Fresnel coefficients for the normal incidence of electromagnetic radiation on monolayer graphene introduce the second, negative fine-structure constant $\alpha_2^{-1} \approx -140.178$ as a fundamental constant of nature and this constant introduces these imaginary base Planck units along with this negative parameter $c_n \approx -3.06 \times 10^8~\text{[m/s]}$. Neutron stars and white dwarfs, considered as \emph{objects} emitting perfect black-body radiation, are conjectured to possess energy exceeding their mass-energy equivalence ratios, wherein the imaginary parts of two complex energies inaccessible for direct observation make storing excess of these energies possible. With this assumption, black holes are fundamentally uncharged; charged micro neutron stars and white dwarfs with masses lower than $5.7275 \times 10^{-10}~[\text{kg}]$ cannot be observed; and the radii of white dwarfs' cores are limited to $R_{WD} < 6.7933~G M_{WD}/c^2$, where $M_{WD}$ is a white dwarf mass. This sets the bounds on charged blackbody objects' minimum masses and maximum radii.

Then give a specific example to verify. Thus prove the Collatz Conjecture is true. Furthermore, analysis the even and odd sequences produced by iteration calculation during the procedure of searching for solution, build a weight function model, prove it decrease progressively to 0, build another complement weight function model, prove it increase to its convergence state. Indicate that this kind of iteration calculation has determined direction, and gradually regularly converges.

Published: March 2023

Background. Oral anticoagulants (OACs) reduce stroke and systemic embolism (SE) in patients with atrial fibrillation (AF) but increase the risk of major bleeding (MB). No study has addressed the incidence and outcomes of bleeding in AF patients in the Middle East (ME). The Jordan AF study evaluated clinical profiles and one-year outcomes of AF patients who sustained bleeding events. Methods. Patients in 29 hospitals and clinics (May 2019 - December 2020) were enrolled and followed up for one year. Demographics and one-year events were compared in patients with or without bleeding. Results. Of 2018 patients enrolled; 166 patients sustained MB or clinically relevant non-major (CRNM) bleeding (8.2 events per 100 patient-years), including 47 patients who had MB (2.3 events per 100 patient-years). Compared with 1852 (91.8%) patients who did not have bleeding, patients with MB were older and had a higher prevalence of hypertension, diabetes mellitus (DM), heart failure, and malignancy, More patients with MB than those with no bleeding were using OACs (93.6% vs. 78.9%, p=0.02). Patients with MB had significantly higher one-year rates of stroke/SE (23.4% vs. 3.6%, p<0.0001) and all-cause mortality (31.9% vs 11.6%, p=0.001). Independent predictors of MB were stroke/SE (OR 10.8, 95% CI 5.3-21.9, p<0.0001), malignancy (3.4, 1.3-8.5, p=0.01), use of OACs (4.4, 1.3-14.7, p=0.02) and DM (1.9, 1.0-3.5, p=0.04). Conclusions. MB and CRNM bleeding occurred in (≈8%) of patients with AF at one year. Patients with MB (≈2%) had worse baseline clinical profiles and one-year prognosis compared with those who did not have bleeding.

Published: March 2023

Lactobacillus plantarum has been observed to play a crucial role in shaping the sensory properties of chili sauce. However, the specific taste-active metabolites responsible for the desirable flavor profile of chili sauce remain inadequately characterized. This study employed a combination of metabolomics and web-based computational tools analysis to investigate the dynamic changes in taste-active metabolites during chili sauce fermentation. Initially, metabolites were rapidly annotated using a feature-based molecular network, leading to the tentative annotation of 206 metabolites, of which a significant proportion had not been previously reported. Subsequently, the VirtualTaste tool identified dihydrosphingosine, lactic acid, isoleucine, phytosphingosine, and gluconic acid as potential taste markers for quality control. Finally, pathway enrichment analysis revealed that these components were primarily associated with amino acid tRNA, phenylalanine, tyrosine, and tryptophan biosynthesis, as well as sphingolipid metabolism. This study provides valuable insights into the mechanisms underlying the formation of the distinctive flavor of chili sauce.

Published: March 2023

This study was carried out to identify the behaviour of Escherichia coli O157:H7 and of Listeria monocytogenes inoculated in Maronesa breed beef with different ultimate pH (pHu) (Normal and DFD), and stored at two different temperatures (4 and 9 ºC), during 28 days post mortem (pm). The main objective was to illustrate the problematic feature of dealing with beef meat showing high pHu and stored at mild abusive temperatures (9 ºC). Beef steaks (ms. longissimus dorsi) were inoculated with low levels (ca. 2 or 3 log CFU/g) of these both pathogens and packed in air, vacuum and three gaseous mixtures with decreasing O2 and increasing CO2 concentrations (MAP70/20, MAP50/40 and MAP30/60). At 4 ºC, the growth of E. coli O157:H7 presented the same pattern on Normal and DFD meat. On contrary, the growth of L. monocytogenes was higher on DFD meat, revealing the effect of the pHu and its psychotropic character. At abusive temperature, both pathogens grew, achieving high levels on DFD meat. In these cases, the MAP with the highest CO2 concentration (60%) revealed to be more effective against the development of E. coli O157:H7, presenting the lowest number of counts.

Published: March 2023

Background: The SARS-CoV-2 laboratory PCR tests were generally reported only as binary positive or negative outcomes. Instead test positivity, these results contain a great deal of epidemiological information related to viral transmission patterns in populations. These transmission patterns during India’s SARS-CoV-2 viral waves remain largely undocumented. Methods: We analysed 2.7 million real-time polymerase chain reaction (PCR) testing records collected in Mumbai, a bellwether for other Indian cities. We used the inverse of cycle threshold (Ct) values to determine community-level viral load. We quantified wave-specific differences by age, sex and slum population density. Results: Overall PCR positivity was 3.4% during non-outbreak periods, rising to 23.2% and 42.8% during the Aleph (June-November 2020) and Omicron waves (January 2022), respectively, but only 9.9% during the Delta wave (March-June 2021). The community-level median Ct values fell and rose ~7-14 days prior to PCR positivity rates. Viral loads were 4-fold higher during the Delta and Omicron waves than during non-outbreak months. The Delta wave had high viral loads at older ages, in women and in areas of higher slum density. During the Omicron wave, differences in viral load by sex and for slum density had disappeared, but older adults continued to show higher viral load. Conclusions: Mumbai’s viral waves had markedly high viral loads representing an early signal of pandemic trajectory. Continue the vaccination in elderly Indians could reduce viral load in subsequent waves. Ct values are practicable monitoring tools.
18F-FDG PET-Derived Volume-Based Parameters To Predict Dis-Ease-Free Survival in Patients With Grade III Breast Cancer of Different Molecular Subtypes Candidates to Neoadjuvant Chem-Otherapy

Published: March 2023

Aim: This study aimed to investigate whether baseline 18F-FDG PET-derived semiquantitative parameters could predict disease-free survival in patients with grade III breast cancer of different molecular subtypes undergoing neoadjuvant chemotherapy (NAC).
Materials and Methods: Patients were retrospectively retrieved from the databases of two Italian hospitals (University of Padua and University Hospital of Ferrara). Inclusion criteria were: 1) histologically proven diagnosis of grade III breast cancer; 2) history of NAC; 3) execution of a baseline 18F-FDG PET/CT scan before the start of NAC; 4) adequate follow-up time to compute the 3Y-DFS. For each 18F-FDG-PET/CT scan, the following parameters were calculated in the primary tumor (SUVmax, SUVmean, MTV, TLG) and whole-body (WB_SUVmax, WB_MTV, and WB_TLG). Receiver operating characteristic (ROC) analysis was used for each parameter to assess the prediction capability for 3Y-DFS. DFS differences between groups were assessed using Kaplan-Meier curves and compared by log-rank test.
Results: Ninety-five grade III breast cancer patients with different molecular types were retrieved (luminal A: 5; luminal B: 34; luminal B-HER2: 22; HER2-enriched: 7; triple-negative: 27). In the whole group of patients, WB_SUVmax was the best predictor of recurrence (AUC: 0.66; best cut-off: WB_SUVmax>9.43; SS: 96%; SP: 38.1%; p<0.008). Patients with luminal A and Her-2-enriched breast cancer types were excluded from the molecular subgroup analysis due to the small study samples (5 and 7, respectively). In luminal B patients (n=34), WB_MTV (AUC: 0.75; best cut-off: WB_MTV>195.33; SS: 55.56%, SP: 100%; p=0.002) and WB_TLG (AUC: 0.73; best cut-off: WB_TLG>1066.21; SS: 55.56%, SP: 100%; p=0.05) were the best predictors of 3Y-DFS. Patients had a higher probability of DFS in case of a WB_MTV≤195.33 (3429±210 vs. 446±144 days; p<0.001) or WB_TLG≤ 1066.33 (937.35±19 vs. 496±131 days; p<0.001). In luminal B-HER2 patients (n=22), WB_SUVmax was the only predictor of 3Y-DFS (AUC: 0.857; best cut-off: WB_SUVmax>13.12; SS: 100%; SP: 71.43%; p<0.001); patients with WB_SUVmax≤13.12 had a significantly longer DFS (3857 days) than patients with a WB_SUVmax >13.12 (1693±430 days; p<0.004). No parameter resulted significant in the prediction of 3Y-DFS in patients with grade III triple-negative cancer.
Conclusion: Volume-based parameters, extracted from baseline 18F-FDG PET, seem to be promising tools in the prediction of recurrence within 3 years in patients with grade III luminal B and luminal B- HER2 breast cancer undergoing NAC. Larger study samples are needed to confirm these preliminary findings.
Decentralized Control for the Cell Power Balancing of a Cascaded Full-Bridge Multilevel Converter
Authors: Vivert Miguel , Diez Rafael , Cousineau Marc , Bernal Cobaleda Diego , Patino Diego
Published: March 2023

In modern inverter applications, multilevel converters are used thanks to their capability of reducing the passive fi lter volumes, improving the overall THD, sharing the power sources across the several converter cells, and providing a reconfi guration ability in case of failure. However, increasing the number of cells makes more complex the control of the converter. This article proposes a decentralized control technique based on the use of elementary modular controllers, associated with each converter cell and communicating with their close neighbors to obtain the balancing of the powers they supplied. Each modular controller can be dynamically removed or added to allow reconfi guration of the converter for functional safety purpose. This method is applied to a 240V/3A 5-cells Cascaded Full-Bridge Multilevel Converter. The response of the system to load transients and cell voltage disturbances demonstrates the robustness of the proposed decentralized control method. Thanks to the use of modular controllers, the number of levels of the converter can be extended to the order N without adding complexity to its control.
Additive Manufacturing by the Selective Paste Intrusion Method: Effect of the Distance of the Print NozzIe to the Particle bed on the Print Quality
Authors: Straßer Alexander , Haynack Alexander , Kränkel Thomas , Gehlen Christoph
Published: March 2023

The Selective Paste Intrusion (SPI) method is a layer-by-layer additive manufacturing technique that allows for the production of complex geometries in concrete elements by selectively bonding aggregates with cement paste in a particle bed. To create reinforced concrete, the Wire and Arc Additive Manufacturing (WAAM) process shall be integrated into SPI. This technique allows the production of almost free-formed reinforcement and thus complements the advantage of SPI to produce free-formed structures of almost any geometry. However, integration of WAAM into SPI poses a considerable challenge, as high temperatures are generated during the welding process. These temperatures can negatively affect the rheological properties of the cement paste, in turn the penetration behavior of the paste in the particle bed and, subsequently, the mechanical properties of the hardened concrete. A possible passive cooling strategy is to increase the protruding length of the reinforcement bars out of the particle-bed. This requires that the distance of the print nozzle to the particle bed is as well increased, since it must be possible to move it across the reinforcement. The objective was thus to investigate the effect of that distance on print quality and to quantify a maximum allowable distance for an adequate print quality (for the printer setting used) in terms of shape accuracy and concrete strength. Compressive and flexural strength tests as well as geometrical measurements using a 3D scanning method were performed on specimen, printed with varying print nozzle to particle bed distances. It can be stated that for the used SPI print-heads, nozzle-types and parameter settings, the distance between the nozzle and the particle bed should not exceed 50 mm to ensure sufficient print quality in both shape accuracy and mechanical strength.

Published: March 2023

The study investigated the major Causes of inconsistency in the cast results of the aluminium cast products from the metal moulds supplied by the then Hungarian Technical Partners to Scientific Equipment Development Institute, Minna. The metal moulds for different scientific products for Schools Scientific Laboratories were to achieve mass production of these products. The aluminium alloy A6063 ingot used were likewise imported. However, another consignment of the ingot used is produced in Nigeria by Nigerian Aluminium Extrusion Company, Lagos. Result of the products defects including shrinkage, blow holes, etc. remained the same, hence the need for this investigation work to ascertain the causes traceable to either moulds or the class or group of alloys.The outcome as shown could be that pouring speed or melting temperature etcetera are responsible for the inconsistency in obtaining acceptable cast products at different operations and with these moulds. A particular product mould gives inconsistent cast products and varying defects. This is applicable to all the available moulds supplied to the Institute at the same time.

Authors:   , Alegría Lerzundi Gonzalo Alfredo
Published: March 2023

El presente trabajo tuvo como objetivo la evaluación de la adición de un emulsificante nutricional en dietas de pollos de carne, medido a través de su comportamiento productivo (peso vivo, ganancia de peso, consumo de alimento, conversión alimenticia y mortalidad). 90 pollos machos de la línea Cobb 500 de 1 día de edad, fueron criados para este experimento, los cuales se distribuyeron al azar en tres grupos o tratamientos de 30 pollos cada uno y cada tratamiento fue alimentado Ad Libitum. Los tratamientos fueron control positivo o T1; control isonutritivo igual al T1 con adición del emulsificante considerando su matriz (160 kcal / kg de emulsificante) o T2 y un control negativo con una disminución de 80 kcal en la dieta sin la adición de emulsificante o T3. La duración del experimento fue de 21 días. Los parámetros que se midieron fueron peso vivo, ganancia de peso, consumo de alimento, ganancia de peso y mortalidad. Los resultados del experimento no presentaron diferencias estadísticas significativas entre los tratamientos para todos los parámetros productivos, sin presentar mortalidad en ninguno de los tratamientos. En conclusión, los pollos alimentados con adición de emulsificante y disminución de aceite en la dieta mostraron un comportamiento similar a los pollos alimentados con una dieta convencional.

Complex Operation to Insert Coiled Tubing Through Parted Production Tubing and Regain Pressure Integrity for Plugging and Abandonment
Authors: Rondon Fajardo Sergio A , Adams Edward
Published: March 2023

At the end of 2020, complex well anomalies were identified in the previously shut-in, highly deviated well A in deepwater Gulf of Mexico. Closely monitored wellbore pressures indicated A/B annulus communication, and remedial slickline diagnostics discovered the tubing was parted between ~4,250 and 4,270 ft measured depth.

The abnormal well conditions and the presence of a single barrier on both the A-annulus and B-annulus triggered the well anomaly process, and action was taken to mitigate the risk profile by commencing abandonment operations prior to the start of the hurricane season.

The well anomaly risk assessment indicated the highest risk was the single barrier on the B-annulus as it had a history of failures and repairs. The outcome was to attempt to further mitigate the risk profile by commencing zonal isolation operations. To achieve a safe operation, a real-time coiled tubing (CT) downhole measurement system and dynamic interpretation software were used to mitigate the risks involved in accessing the lower section of the parted production tubing, pressure testing the completion, perforating the tubing, confirming the firing of the tubing-conveyed perforating guns, and pumping a balanced cement plug in the tubing and annulus after setting the cement retainer.

This study proposes an innovative approach to integrating CT, telemetry, and mechanical wellbore isolation tools to increase operational efficiency. Real-time bottomhole pressure, temperature, and casing collar locator (CCL) measurements proved invaluable by providing the necessary guidance to successfully set the inflatable packer and fire the perforating guns. They also provided pressure confirmation that tubing integrity issues did not allow cement in the A-annulus to escape into the production tubing on to the backside of the CT.

Sand production remains one of the major challenges in managing mature fields in Malaysia. Wells that experience severe sand production due to primary sand control failure require remedial solutions to continue producing without jeopardizing asset integrity. In these cases, operators rely heavily on through-tubing metallic sandscreen (TTSS), however, the applications remain limited due to the short TTSS lifespan, especially in wells in a high erosive environment. With increased intervention risk, frequent replacement is both economically and operationally unfeasible. Therefore, most high gas-oil ratio (HGOR) wells remain closed-in today, in need of a durable sand screen that can withstand high erosional velocity. Various types of erosion resistant through-tubing sand screens (ER-TTSS) have been implemented to test their sustainability and longevity in highly erosive environments. Additional challenges can be associated with the actual deployment of these remedial solutions into mature wells.

This paper will discuss the performance of Malaysia's first installation of bonded bead sandscreen in HGOR well, Well #1 at offshore East Malaysia. Instead of using conventional mesh or wire wrapped type as filtration media, bonded bead sandscreen incorporates tightly bonded beads to filter sand and is expected to have superior performance over conventional metallic TTSS. Prior to installation, computational fluid dynamic (CFD) simulation and sand retention test (SRT) were conducted to determine sand erosion risk and optimize the screen design for Well #1. The information gathered from the CFD was then utilized to optimize the tubular components and minimize the effect of erosion on the complete bottom hole assembly (BHA). Additionally, well #1 was on an unmanned production platform; therefore, the deployment options for this intervention had to be considered during the early planning phase of the operation. A combination of slickline unit with suitable pressure control equipment was selected to minimize personnel on board and match deck load limitations while ensuring proper service delivery.

The outcome of pilot testing of bonded bead sandscreen in Well #1 will be discussed. Recommendations for future optimization will also be included to ensure that bonded bead sandscreen remains one of the competent through-tubing sand solutions, especially for HGOR wells. Furthermore, the operational techniques that were utilized to reduce the operational risk and costs will be discussed in order to demonstrate how such wells can be intervened in a cost-effective manner to extend the asset's life.
