Background: Respiratory distress syndrome (RDS) is known as hyaline membrane disease (HMD). It is the major cause of neonatal respiratory distress, especially in preterm infants Infants with RDS present with tachapnea, cyanosis, grunting, subcostal and intercostal retractions and nasal flaring. Oliguria with mild generalized edema may be present. Oxygen requirement may increase rapidly and is typically higher than that seen in infant with transient tachapnea of the newborn (TTN).
Objective: to evaluate the relationship between the maternal and cord blood lipid profiles in preterm babies with respiratory distress syndrome.
Methods: This is a case control study which was conducted on 50 preterm neonates admitted to the neonatal intensive care unit of Shebin El-Kom teaching hospital between January 2020 and October 2021.
Results: the mean of total cholesterol was significantly higher in infants whose mothers had received antenatal steroid for lung maturity than those whose mothers had not (P<0.05). But there was no significant difference in the mean of levels of TG, HDL-cholesterol, LDL-cholesterol and VLDL cholesterol between both groups. Also, There is a positive correlation between weight gain during pregnancy and neonatal cord blood levels of (Total cholesterol, TG, HDL-C, LDL-C and VLDL-C), There is a positive correlation between maternal blood levels of (total cholesterol, TG, LDL-C and VLDL-C) and their neonatal cord blood levels of (total cholesterol, TG, HDL-C, LDL-C and VLDL-C), There is a positive correlation between the maternal blood level of HDL-C and their neonatal cord blood levels of (total cholesterol and HDL-C).also, the cutoff values of cord blood (total Cholesterol, HDL-C, and LDL-C) below which RDS can be predicted are 80, 45.5 and 23.2 mg/dl respectively with a sensitivity of 83.3%, 86.7% and86.7% and with specificity of 95%, 80% and 70% respectively.
Conclusion: RDS is accompanied with lipid alteration in the infants and their mothers. The results of this study point to the importance of measuring maternal serum and cord blood lipid profile as a predictor for the occurrence of RDS.

Authors: Kutsiyatur Rahmah
Published: November 2024

Pemberian amplop dalam acara walimatul urs merupakan tradisi yang dilakukan oleh masyarakat desa Sokolelah. Akan tetapi meskipun pemberian amlop sudah menjadi tradisi, mayoritas masyarakat desa Sokolelah merasa keberatan, karena bagi  mereka acara walimatul urs  adalah bentuk rasa syukur mempelai dan sudah seharusnya berbagi dengan tetangga dan sanak saudara. Dengan adanya pemberian amplop pada acara walimatul urs maka tidak ada bedanya walimatul urs dengan apa yang disebut resepsi. Penelitian ini menggunakan metode normative - empiris dengan jenis penelitian lapangan (field research). Dari hasil penelitian penulis bisa menyimpulkan bahwa pelaksanaan walimatul urs yang dilaksanakan oleh masyarakat desa Sokolelah sudah mengalami pergeseran makna dan esensi. Sedangkan tinjaun dalam hukum Islam walimatul urs dengan pemberian amplop hukumnya boleh karena pemberian amplop pada acara walimatul urs bisa dikatakan hadiah atau hibah kepada penyelenggara acara.

HBV infection is one of major global health problems worldwide. It increases the morbidity and mortality rates among hemodialysis patients which make the management process more complicated. This study was aimed to determine the prevalence of HBV infection among hemodialysis patients and assessment the risk factors associated with infection. An analytical cross-sectional study was conducted on 50 HD patients. Blood samples were collected and serum HBsAg was analyzed using ELISA technique. The overall prevalence of HBV was 6 (12.0%). The males had highest rate. There were statistically significant recorded between the prevalence of HBV infection and age group 30 – 39 years and duration of hemodialysis from 1-2 years and more than 2 years (p=0.02, 0.001 and 0.001) respectively. It can be concluded that the HBV prevalent rate among HD patients was common and lower than that reported among most general population in Yemen. Increasing of the duration and long standing in hemodialysis unit may increase the risk of HBV infection. Hepatitis B vaccine should be given to all HBV negative HD patients before HD process and health education programs about the transmission routes of HBV and preventive measures should be implemented for general population.

Abstract
This research was aimed to examine the habitat characteristics, growth patterns and condition factors of T. tambra in the Mamis River, Leuser Ecosystem Area, Aceh, Indonesia. This research was conducted on the Mamis River in three different river conditions from July to August 2023. The ecological parameters of T. tambra were conducted by observing the main, broodstock, spawning, and nursery ground habitats based on diversity of catch size at a location, water quality, aquatic substrate, aquatic vegetation, and water shade. The growth pattern parameter was also analyzed to reveal the condition of T. tambra.  The T. tambra habitat in the Mamis River includes broodstock and spawning habitat with the criteria from small to large rocks overgrown with Bryophytes, gravel and sand substrates, clear water color, slow to swift water currents, and river environment most of it is primary forest. In the main habitat, there is dominant riparian vegetation in the form of forest timber trees such as Pometia pinnata, Ficus fistulosa, Hydnocarpus castanea, and Aglaia tomentosa. The habitat for the juvenile is in the form of rocks, gravel substrate, clear water color, and fast water currents. In the nursery habitat, the dominant riparian vegetation is Balakata baccata. Based on the results of water quality analysis at the three stations, it shows that temperature, pH, DO, currents, BOD, COD are significantly different, but brightness levels are not significantly different. Based on the analysis of the length-weight relationship, it shows that the condition of the fish is stable with sufficient food availability.

Abstract
Vietnamese balm (Elsholtzia ciliata) is a prominent herb in Vietnamese traditional medicine. This study investigated the impact of Vietnamese balm leaf essential oils on the growth of striped catfish (Pangasianodon hypophthalmus) in the juvenile stage. Essential oils were extracted using steam distillation, following European Pharmacopoeia guidelines. Gas chromatography-mass spectrometry identified the essential oil components. The experiment encompassed three treatments: 0% (control), 3%, and 5% of Vietnamese balm leaf essential oils in a completely randomized design. The results demonstrated a time and dose-dependent modulation of striped catfish growth by the essential oils. Diets enriched with 5% Vietnamese balm leaf essential oils significantly enhanced survival rate and growth, indicating potential as a fish feed additive. The essential oil yield was 0.83% dry weight, with major components including (Z)-β-Farnesene (24.02%), neral (15.06%), geranial (15.02%), and β-ocimene (13.61%). Additionally, the study emphasized the growth-promoting effects of herbal extracts on various growth parameters. Further investigations should explore the impact of Vietnamese balm essential oil on catfish immune response and disease resistance, providing a comprehensive understanding of its potential benefits.

1. Lymphocystis disease is reported to infect seawater and freshwater fishes
2. The four important freshwater fish species in Indonesia are evaluated on their susceptibility to Lymphocystis Disease Virus
3. Lymphocystis infection causes behavioural changes and mortality with different onset times after infection on the four fish species
4. LCDV load is varied in quantity among different organs.
Abstract
Lymphocystis disease has a broad host range and has been reported to enter Indonesia. However, information regarding its susceptibility and predilection organs in fish is lacking. This study examined the susceptibility of four important fish species in Indonesia, namely, giant gourami (Osphronemus goramy), hybrid tilapia (Oreochromis sp.), Siamese fighting fish (Betta splendens), and hybrid catfish (Clarias sp.). The fish were infected with virus filtrate by intraperitoneal injection and immersion. The postinfection observation period was 60 days. Viral load was quantified by qPCR and expressed as major capsid protein (MCP) copy number/mg tissue. Mortality was observed in all fish species, with the highest recorded in hybrid catfish and the lowest in Siamese fighting fish. All the fish species showed changes in their clinical symptoms, such as anorexia and separation from schools. However, only giant gourami showed internal change seven days after injection (dpi), with white lesion detected in the liver. Viral load quantification showed that LCDV had different predilection organs in the four fish species. The highest viral load of giant gourami (1.7 x 104) was observed in the liver at 7 dpi, hybrid tilapia (7.5 x 103) was observed in the fins at 21 dpi, Siamese fighting fish (8.4 x 103) was observed in the fins at 14 dpi, and hybrid catfish (1.2 x 103) were observed in the fins and gills at 7 and 14 dpi. The findings indicated that giant gourami, hybrid tilapia, Siamese fighting fish, and hybrid catfish were susceptible to LCDV infection with different predilection organs.

Geoacoustic characteristic.
Sediment type spatial distribution in Lancang Island.

AbstractHydroacoustic technology was able to quantify the seabed substrate and can be estimated accurately and near real time on the acoustic characters of each substrate. The purpose of the research was to identify the geoacoustic characteristics and spatial mapping of the seabed substrate in Lancang Island. Acoustic data was acquired using a Simrad EK-15 Single Beam Echosounder instrument operating at 200 kHz. Sediment samples were taken using an Ekman grab, which will be used to validate the acoustic data. The results of this study indicated that the acoustic backscatter values of the seabed substrate based on the surface backscattering strength value and sediment particle size at fourteen sampling stations are -28.03 decibels to -20.02 decibels divided into 9 sediment type groups, namely medium and very coarse sand mixture; medium sand; medium, fine and coarse sand mixture; medium and fine sand mixture; fine and medium sand mixture; medium and very fine sand mixture; very fine and medium sand mixture; fine and very fine sand mixture; and fine sand. The accuracy level of k-Nearest Neighbour and Random Forest computational used has very good accuracy of 98.21 % and 96.43 % and Naevi Bayes has a lower accuracy of 58.93 %. The identified geoacoustic characteristics included the mean grain size, sound speed, density, acoustic impedance, and reflection coefficient. Faster, more effective, and efficient computational processes with high accuracy make k-Nearest Neighbour and Random Forest models the best alternative to be used as geoacoustic computational models of seafloor substrates.

Lola snails originating from the Bangka Belitung Islands (Nasik Strait, Rebo Waters, and Ketawai Island) were identified as a maxima not to be R. nilotica species based on morphological molecular identification.
Maxima and R. nilotica have the same morphological form, but they are genetically different.
The clarification of the Lola snail species in this study serves as a reference in determining the conservation status of the Lola snail.
The clarification of the Lola snail species serves as a reference in determining the catch quota from the Bangka Belitung Islands.

Abstract
The use of Lola snails (Rochia maxima) in the Bangka Belitung has continued to increase. However, research focused on Lola snails originating from the Bangka Belitung has not been thoroughly conducted. In a previous study, the Lola snail sample found in the Bangka Belitung was Trochus niloticus (current name: Rochia nilotica). This study aimed to identify Lola snail species using the DNA barcoding as a way of clarifying Lola snail species that originated in the Bangka Belitung. Lola snail sampling was carried out at three locations, which were Nasik Strait, Ketawai, and Rebo Waters. This study was conducted through five stages, including Lola snail tissue sampling, DNA extraction, amplification by PCR, sequencing, and data analysis. The results showed that the molecular identification of the Cytochrome Oxidase Subunit 1 (COI) gene in Lola snail samples was identified as Rochia maxima species (Koch, 1844). The results of the phylogenetic tree analysis showed that Lola snails found in the Bangka Belitung were close to Tectus maximus (or Rochia maxima) species. R. maxima has a lighter shell than R. nilotica, a clear conical shape, and a circle on the body that does not widen at the edges. Unlike zoologists who said that R. maxima is the primitive form of R. nilotica, the present study found that they have the same morphology and are considered similar but genetically different. The clarification of Lola snail species can be used to determine the conservation status and catching quota of Lola snails from the Bangka Belitung.

The author mentioned four highlights from their research:
1. Pangasius aquaculture in Tulungagung Regency continues to increase
2. GIS can be used to determine the suitability of aquaculture land
3. AHP can be used to determine the weight of aquaculture land suitability parameters
4. The development of aquaculture areas must consider other land uses.
Abstract
Tulungagung Regency in East Java Province has an export demand of 300,000-400,000 tons per year. The high demand for exports spurred the people and government of Tulungagung Regency to develop pangasius aquaculture areas. This will have a negative impact if carried out without a land suitability assessment. The study aimed to analyze the parameters of pangasius aquaculture and map the potential areas for pangasius aquaculture using AHP and GIS-based analysis. This research was conducted from January to August 2022 in Tulungagung Regency, Indonesia. Several stages were carried out, including primary data collection (water quality, soil quality, and infrastructure), secondary data collection (literature, reports, fisheries statistics data, government statistical data, and journals/articles), application of land suitability assessment, and pangasius farming area suitability analysis. Land suitability analysis consists of measuring water quality parameters (DO, temperature, TDS, pH, ammonia, and nitrate), soil quality (texture, pH, and slope), and infrastructure (roads, markets, hatcheries, and fillet factories) using the Analytical Hierarchy Process method (AHP), which includes standardization, determination of weights, and combining the weights of land suitability maps, which are then mapped by ArcGIS Software. Most of the land conditions for the pangasius aquaculture areas in Tulungagung Regency are moderately suitable, suitable, and most suitable, with percentages of 30, 21, and 28%. The area that can be developed for pangasius aquaculture is 976885.71 ha, with the most suitable category being 2619.35 ha, the appropriate category being 2235.74 ha, and the most suitable category being 4913.77 ha.

The high haplotype diversity of lemuru is a testament to its adaptability.
S. lemuru's high haplotype diversity supports their stock recovery in the Bali Strait.
Two sardine species are morphologically and genetically highly distinct, even though they prefer overlapping water mass conditions from each other.

Abstract
Sardinella lemuru is known as the native pelagic fish of the Bali Strait. However, its presence has become difficult to find recently. This study aimed to validate S. lemuru using molecular taxonomy and link it to water circulations for sustainable management. It is the first study of relatively complete sequence data on S. lemuru in the Bali Strait. A total of 47 sequences were amplified using the control region gene of mitochondrial DNA. Other S. lemuru (n = 4) and Amblygaster sirm (n = 12) sequences were retrieved from GenBank. Low sequence divergence is observed in clade-1 of S. lemuru across the Bali Strait, Manado-Sulawesi, and Kudat-Malaysia. This is probably due to its migration using the main Indonesian ThroughFlow (ITF). There is evolutionary divergence between two groups of S. lemurs, measuring 35.3%±4.1. The first signs of these cryptic groups were found at Canggu and Prigi, with 87 base-pair differences between the two groups. This study also presents strong evidence that A. sirm prefers overlapping water mass conditions with S. lemuru in the Bali Strait but is morphologically and genetically distinct. Notably, three samples of A. sirm in Kedonganan-Bali are clustered with other A. sirm locations passed by the primary and secondary South China Sea throughflow. The high genetic diversity of S. lemuru among Bali Strait sites demonstrates its adaptive ability, with scattered single-frequency haplotypes. The adaptive ability traits of S. lemuru support its stock recovery. The stock recovery recommendation is based on finding S. lemuru's adaptive traits within their populations in suitable habitats and climatic conditions.

Published: November 2024

Introduction: Depression in the elderly is often not detected because elderly people who are depressed show more somatic or cognitive complaints than affective complaints. The relationship between depression and the progression of glaucoma has been studied and taken into consideration in the selection of therapy to be given. Methods: This report is a case report from a patient who has been given an explanation and received consent regarding a psychiatric interview, physical examination and support, interventions, case discussion presentations, and the confidentiality of all patient personal information. Case: Education was carried out on a 72-year-old patient with a Major Depressive Episode without psychotic symptoms who also had glaucoma a few months after complaining of depression. The education provided includes knowledge about depression and its relationship to glaucoma, a management plan in the form of advice for hospitalization in a hospital that has a psychiatrist and an ophthalmologist. Conclusion: Depression in the elderly can affect the progression of glaucoma. The choice of psychopharmacological therapy needs to be adjusted by considering its side effects on the possibility of glaucoma or the risk of aggravating the progression of glaucoma.
Neuropsychiatric Symptoms in Corticosteroid Induced Systemic Lupus Erythematosus (Sle) Patients: a Case Report
Authors: Tri Ratnawati
Published: November 2024

Introduction: Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease with an unknown etiology and various clinical manifestations, course, and prognosis. Classes of medication used in the management of SLE include non-biological immunosuppressives, corticosteroids, biologic therapy, and immunoglobulins. The effect of using corticosteroids in the management of SLE still evokes debate regarding the emergence of mental health disorders. Case: A 24-year-old female patient was admitted to the hospital with an initial diagnosis of acute confusional stage, anemia, chronic disease, and systemic lupus erythematosus (SLE). Anticonvulsants, corticosteroids, and packed red blood transfusions had been given to the patient. The course of the disease during the hospitalization the next days, the patient experienced slurred speech, giggling, place and time disorientation, and visual hallucinations. The patient was consulted to a psychiatrist, got atypical antipsychotics and benzodiazepines, and then experienced improvement. Discussion: Patients with moderate SLE, in this case characterized by lupus nephritis, were given corticosteroids. Administration of corticosteroids to SLE patients will increase the risk of developing neuropsychiatric symptoms such as acute confusional state, anxiety, mood disorders, cognitive disorders, and seizures. This can occur due to increased permeability of the blood-brain barrier mediated by pro-inflammatory cytokines, resulting in the formation of autoantibodies against neural antigens, in which phospholipid proteins appear intracranially. Conclusion: Corticosteroid administration in SLE will cause neuropsychiatric symptoms such as slurred speech, giggling to herself, delirium, and visual hallucinations. Further design studies are needed to address the neuropsychiatric effects of corticosteroids in SLE.
The impact of people’s participation on public policy satisfaction in Vietnam
Authors: Trung Phan Nhan
Published: November 2024

People’s participation in public decision-making not only helps ensure transparency and accountability but also contributes to improving their satisfaction with government policies and operations. This study examines whether transparency in decision-making, trust in public agencies, access to information, and people’s awareness of their rights and responsibilities play an important role in promoting their participation. The study also explores whether this participation directly affects people’s satisfaction with public decisions and policies. This study uses mixed method approach through the SEM linear regression model. The analysis of the results shows that transparency, trust, information accessibility and citizen awareness have a positive and significant impact on the level of their participation in public activities. However, increased participation does not necessarily lead to higher levels of satisfaction with public policies, especially when the participation process does not meet people’s expectations or lacks transparency and efficiency. The study concludes that, to improve people’s satisfaction, it is necessary not only to promote participation, but also to improve the quality of this process, ensuring that participation is substantive and has a clear impact on public decisions. As such, specific recommendations are made to improve public policy and enhance people’s participation and satisfaction in the context of modern public governance.

Aim: To investigate radiotherapy efficacy and prognostic factors in patients with hepatocellular carcinoma (HCC) with cardiophrenic angle or superior diaphragmatic lymph node metastasis (LNM).

Methods: We retrospectively analyzed 72 patients with HCC presenting with cardiophrenic angle or superior diaphragmatic LNM at Zhongshan Hospital of Fudan University from 2010 to 2023. Response rates, survival rates, local control rates, prognostic risk factors, and side effects of external beam radiation therapy (EBRT) were compared between patients with EBRT (EBRT group) and those without EBRT (non-EBRT group).

Results: The overall response rates in the EBRT group and the non-EBRT group were 68.8% (22/32) and 7.5% (3/40), while median survival was 16.1 (95%CI: 8.09-24.12) and 5.9 months (95%CI: 3.05-7.76) respectively (HR = 2.87, P < 0.001). The survival was significantly prolonged with a daily dose > 4 Gy (P = 0.014). EBRT (P < 0.001) was identified as a factor correlated with the local control rate. Multivariate analysis revealed that tumor thrombosis, multiple intrahepatic tumors, a maximal intrahepatic tumor diameter ≥ 5 cm, abdominal LNM, and lack of EBRT were poor prognostic factors. Gastrointestinal (GI) bleeding in patients with bioequivalent dose 10 (BED10) ≤ 70 and > 70 were 0% (0/22) and 30.0% (3/10), respectively (P = 0.024).

Conclusion: EBRT was a safe and effective treatment for HCC patients with cardiophrenic angle or superior diaphragmatic LNM and might prolong overall survival. Dose > 4 Gy per day and BED10 ≤ 70 would be recommended for LNM. Patients with tumor thrombosis, multiple intrahepatic tumors, a maximal intrahepatic tumor diameter ≥ 5 cm, abdominal LNM, and lack of EBRT had a poor prognosis.

In this article I describe Rosa's theory of resonance. I argue that resonance has a relevance in a capitalist society. Following this, I explore both losing and having career resonance and how this impacts well-being and has association with psychological burn-out. Next, I introduce career resonance and suggest how career professionals may help clients to foster resonance through their work. Finally, I emphasise that career resonance has a part to play in addressing psychological burnout and that career professionals may be called to deepen understanding and form collaborations with well-being professionals. In conclusion, I emphasise that human beings are born resonant and that career resonance has a relevance to everyone.

Background: Effective stroke treatment is complicated by factors such as polypharmacy, drug interactions, and side effects, leading to drug-related problems (DRPs) that hinder therapeutic outcomes. Evaluating drug use in stroke patients is crucial to ensure rational, safe, effective, and efficient treatment, ultimately improving therapeutic outcomes.
Objective: This study aimed to evaluate the drug use patterns in inpatient stroke patients at Brebes Hospital, focusing on the appropriateness of drug selection, dosage, administration, and the impact of patient characteristics on DRPs.
Method: A retrospective, descriptive evaluative design was employed, with data collected from medical records of stroke patients hospitalized at Brebes Hospital between May and July 2022. A total of 135 patients (110 ischemic, 25 hemorrhagic stroke) were included through consecutive sampling. Univariate analysis was used to describe patient characteristics and treatment patterns, while bivariate analysis with the chi-square test assessed the relationship between patient characteristics and DRPs.
Results: The most common medications included citicoline (88.15%), clopidogrel (68.85%), and amlodipine (40.48%). DRPs were identified, including non-compliance with guidelines (1 case), contraindicated drugs (5 cases), and inappropriate drug selection (1 case). Notably, five cases of contraindicated use of omeprazole with clopidogrel and one case of phenytoin without indication were observed. Patient characteristics such as age and comorbidities did not significantly influence the incidence of DRPs (p > 0.05).
Conclusion: The study found irrational drug use in stroke patients, with DRPs posing challenges for treatment optimization. Addressing DRPs through improved prescribing practices and pharmacist intervention is crucial to enhancing therapeutic outcomes in stroke management.

Hybrid Design Stabilizer/Reamer Helps Driving Drilling Efficiencies in Unconventional Non-Reservoir Vertical Applications in KSA

Drilling a well is a costly process with a high element of risk that requires strict monitoring. Given the high-cost environment, introducing new techniques and innovative technology to high-profile offshore, or remote operations is often more feasible and financially viable for both consumer and provider. Such an exercise is more challenging for comparatively low-cost non-reservoir applications similar to that of rotary bottom hole assemblies (BHAs) used in vertical drilling operations. Hence, the introduction of clever yet relatively simple technology and solutions serving improved well economics is highly desirable.

New complex smart downhole tools and technology typically come with a comparatively hefty price tag. Furthermore, adding components to the BHA will automatically result in increasing the bottom line. Therefore, the primary approach was to replace existing components such as stabilizers and/or roller reamers with a design that offers similar functionality with superior efficiency. A similar innovative device was identified and an initiative was started in order to evaluate this new Efficient Design Stabilizer (EDS) in the 12″ hole section as a starting point. After ascertaining representative offset wells offering a reliable benchmark, a suitable well was then selected for the introduction of the EDS. The idea was to swap out the conventional design stabilizers or roller reamer with the novel design in a packed rotary BHA. A set of clear key performance indicators (KPIs) were also required in order to ensure a qualitative evaluation.

The collation and comparison of the standard drilling parameters produced very encouraging findings. There were noticeable improvements across hydraulics data, mechanics as well as performance data compared to the best offset. Moreover, the introduction of the EDS did not pose any new risks to the operation. The objectives of maintaining verticality were likewise successfully accomplished. Correspondingly, the subsequent casing run proved trouble-free and smooth.

These favourable outcomes were really promising, providing the confidence to pursue utilizing the new design tools, and further introduce them to other hole sections. This paper details the selection process of the EDS and provides a thorough description of the new design features and benefits of the adopted design after specifying well, BHA, and the nature of the application. An analysis of the acquired data is then presented and explained. Finally, the results and gains are summarized and quantified.

The avant-garde archetype of the EDS adheres to the recommended stabilizer selection criteria and guidelines by design and addresses known shortcomings of conventional design stabilizers and roller reamers that are yet widely accepted by the industry. As such, the new design challenges the status quo and offers a cutting-edge substitute for roller reamers and conventional stabilizers better suited for 21st century demands.
Repairing Corrosion Resistant Alloy Clad Pipelines: The Weld or Connect Choice
Authors: Cavallini F. , Girello E.
Published: November 2024

The use of subsea Corrosion Resistant Alloy (CRA) clad pipelines is increasing nowadays, and there are plans to increase even further their laying to develop large reservoirs and transport high temperature, high pressure, highly corrosive fluids. This tendency calls for the development of solutions capable of facilitating a safe and reliable repair intervention, which are going to be presented hereafter.

This paper aims at comparing traditional welded solutions, such as above water repair methods and underwater hyperbaric welded solutions, with the novel options offered by subsea connectors purposely developed for CRA clad pipelines. These connector solutions ensure continuity of containment of the corrosive fluid by means of engineered non-elastomeric, metallic seals, and are qualified according to the most demanding DnV rules, thus allowing the comparison on a pure operational perspective.

Repair connectors for CRA clad pipelines are robust and qualified solutions, and their installation shall follow the same sequence as legacy elastomeric-seal repair connectors, with minor additional preparation required. From a pure intervention perspective then, a dedicated comparison of each step will be provided, thus emphasizing the reduced demand in terms of installation spread, specialized divers as well as tailor made welding procedures requiring constant update and recertification. From a timeline perspective, repair connectors offer valuable alternatives for all such cases where time is really of the essence, such as in the business interruption scenario post intervention. Finally, an assessment of spare pipes is also provided, showing how the pre-selection of an optimized repair solution can effectively reduce the pre-investment needed for spare pipes, especially in subsea congested areas.

Technology development is constantly evolving for the benefit of the energy industry: while CRA clad pipeline repair solutions have been already shown in certain occasions with focus on the technology qualification, a competent and complete assessment of the wide-reaching benefits of such technology has never been presented, and this would be extremely valuable for the Arabian Gulf area.

Throughout its life, every oil and gas well is subjected to many risks with potential detrimental consequences affecting reserve accessibility and resulting in expensive corrective intervention activities. One of those risks threatening wells health is Casing Deformation (CD). CD are notoriously difficult to detect real time, and normally discovered after the fact during subsequent operations. Therefore, understanding of the interdisciplinary context and early symptoms associated with CD is crucial to minimize their occurrence. The objective of this paper is to discuss a CD incident that took place in one of the wells – G-107 in bock-61, describing its silent signature and lessons learned for future field development and production enhancements.

Successfully minimizing, managing, and recovering from CD incidents heavily depend on understanding the geomechanics and geologic context associated with a specific field, the data acquisition and processing of diagnostic tools used, and on well architecture and stimulation design and selection. Additionally, proper operational planning is also critical in reducing and mitigating the economic impact of CD when they occur.

Block-61 is considered one of the biggest gas fields in Oman. Production is mainly from Barik and Miqrat sandstone formations with Barik as the main reservoir. Most of the wells are vertical and few horizontals. On 20 November 2022, after the hydraulic fracturing operation and during bridge plug milling operation in G-107, a restriction was encountered at the top of the perforated interval. Through the application of different diagnostic tools, the restriction was later determined to be a casing ovalization with a minimum cross well diameter of 3.18 in., preventing accessibility to the rest of the well and the associated reserves.

The paper will review the incident investigation approach adopting the five whys methodology, including documentation of the findings and learnings, highlighting the gaps associated with well planning, well architecture and stimulation design, and all the ancillary operations such as perforation. Furthermore, it will describe how difficulties in retrieving records of previous CD incidents should be corrected and not underestimated. A detailed description of the diagnostic tool selection such as downhole camera, multi-finger caliper logs and lead impression block, and the analysis of the data acquired with such diagnostic tools will also be presented. Finally, recovery actions and future changes to the well design will be described aiming for a robust system that does not simply react to the incident but allows mitigating future CD events.
