Gas Lift Optimization for Zubair Oil Field Using Genetic Algorithm-Based Numerical Simulation: Feasibility Study
Authors: O. Al-Mansory Saad Hazem , Al-Fatlawi Omar , Kadkhodaie Ali 
Published: June 2024

The gas-lift method is crucial for maintaining oil production, particularly from an established field when the natural energy of the reservoirs is depleted. To maximize oil production, a major field's gas injection rate must be distributed as efficiently as possible across its gas-lift network system. Common gas-lift optimization techniques may lose their effectiveness and become unable to replicate the gas-lift optimum in a large network system due to problems with multi-objective, multi-constrained & restricted gas injection rate distribution. The main objective of the research is to determine the possibility of using the genetic algorithm (GA) technique to achieve the optimum distribution for the continuous gas-lift injection flows in the structure of the network of Zubair, oil field with 10 gas-lift injected wells. This will be done through numerical simulation and modeling studies. The overall enhancement of the filed production rate is found to have increased from 15767 STB/day to 19847 STB/day. The well's reservoir pressure and water cut sensitivity studies are carried out to study the possible impacts of these elements upon the well and its efficiency through the course of the field. Our understanding of the potential benefits of utilizing gas lift techniques in a field from a technical and economical point of view is deepened by the use of examples from economic analysis. Furthermore, even though the idea of employing GA in this manner is not new, this work discusses GA-based optimization methodologies for increasing the oil production rate by using gas lifting in a Zubair oilfield. In order to assign gas injection rates to specific wells in a network throughout the field using limited gas injection rates, the model for optimization will be laid out step-by-step making it simple to understand and employ as a guide, especially for the front-line production technicians involved in the development and design of gas-lift systems.
A Comprehensive Geomechanical Study to Understand Drilling Challenges in the Eridu Oil Field, Southern of Iraq

Published: June 2024

In recent years, the Eridu oil field has emerged as a key player in the petroleum industry in southern Iraq as it is the biggest Iraqi oil discovery in 20 years. Extending along a vast area of 5806 km2, the field has commercial oil reserves in formations such as Mishrif, Nahr Umr, Zubair, and Yamama. However, drilling operations in this field have faced significant challenges, including delays and suspensions caused by wellbore instability. One of the main obstacles encountered during drilling operations in the Eridu oil field is the occurrence of partial losses in weak vugs dolomite formations, as well as issues related to sever borehole instabilities such as drilling in tight holes, caving, and breakout due to shear failure in the borehole wall. To address these challenges, a 1 D Geomechanical model (1-D MEM) was constructed using data from vertical wells to better understand the underlying causes of drilling problems. The findings of the 1-D MEM, particularly in relation to mechanical rock properties, rock Elasticity factors, pore pressure, and fracture gradient complex formations like Tanuma and Mishrif, were instrumented in planning drilling operations for inclined and highly deviated wells. By utilizing open hole well logging data and calibrating the model with various resources of data including drilling observations, core mechanical analyses, and pore pressure measurements, a more accurate assessment of wellbore instabilities was achieved. The analysis revealed that many of the wellbore instabilities, such as pack-off, breakout, and stuck pipe, were attributed to the insufficient mud weight that failed to support the rock in the borehole wall. To avoid these issues, it was determined that a safe mud weight range of 11-12.5 ppg is necessary to prevent wellbore instability in shale formations. The study also highlighted the importance of using proper mud weight to prevent shear failure and other drilling complications. The findings of this study provide insights that can be utilized as a cost-effective tool for planning directional and horizontal drilling operations in the Eridu oil field. The accuracy of the failure criteria and geomechanical model is significantly superior and aligns with the analysis of breakouts observed in the caliper and image logs.

The aim – to evaluate the association of neutrophil-lymphocyte ratio (NLR) with the clinical course and hospital prognosis of pulmonary embolism (PE).Materials and methods. The study included 291 patients with a diagnosis of PE, verified by multislice computed tomographic pulmonary angiography, with a calculated NLR according to clinical blood count. In addition to the standard general-clinical and laboratory-instrumental examination, patients were assessed for risk factors of PE and risk of early death according to ESC 2019 recommendations. The data obtained were statistically processed.Results and discussion. Patients were divided according to the median NLR: group 1 included 145 patients with NLR <3.4, group 2 – 146 patients with NLR ≥3.4. Also, according to the value of the NLR obtained during the ROC analysis for predicting mortality during the hospital period: group 3 consisted of 245 patients with NLR ≤6.75, group 4 – 46 patients with NLR >6.75. Analyzing demographic indicators, it was found that in group 2, elderly patients (p=0.02) and males (p=0.037) were reliably more common than in group 1. Regardless of the method of division into groups, a reliable predominance of patients at high risk of early death from PE (p<0.001), PESI class V (p<0.01) and high-risk sPESI (p<0.01), with higher PESI scores (p<0.001) was obtained in groups with increased NLR (NLR ≥3.4 and NLR >6.5). In the same groups, analyzing the results of the objective examination, a reliably lower level of saturation (p<0.0001) and SBP (p<0.01) were found. When comparing laboratory parameters, it was found that the average leukocyte levels in the groups with NLR ≥3.4 and NLR >6.5 were reliably higher (p<0.001), and the level of troponin I was reliably increased (p=0.02) only in the group with NLR >6.5. Correlation analysis showed a reliable direct link between the level of NLR and age, heart rate, right atrium (RA) size, LVEDC, mean pulmonary arterial pressure (MPAP), leukocyte and troponin I levels, increased risk of early mortality from PE and hospital mortality, as well as an inverse link with the level of saturation, SBP, LV EF and hemoglobin. Conclusions. The link between the level of NLR and clinical and anamnestic parameters in patients with PE was established. Among patients with NLR above the median (≥3.4), elderly patients, males, and high-risk patients with reliably higher PESI scores predominated. A direct correlation between the level of NLR and age, heart rate, RA size, LVEDC, MPAP, leukocyte and troponin I levels, increased risk of early mortality from PE and hospital mortality, as well as an inverse correlation with saturation, SBP, LV EF and hemoglobin levels were established. NLR >6.5 is associated with an unfavorable prognosis – death in the hospital period, as well as with a higher level of troponin I, a marker of right ventricle dysfunction.

Vida cotidiana e a pergunta pelo humano em Humberto Giannini
Authors: Uribe Íris 
Published: June 2024

O presente texto traz à luz uma discussão que devolve à filosofia a tarefa de pensar o cotidiano; centrado na pergunta pelo humano nas reflexões do mundo hodierno. Esse exercício de reflexão é fundamentado no livro: La “Reflexión” Cotidiana. Hacia una arqueología de la experiencia do filósofo chileno Humberto Giannini. La “reflexión” cotidiana analisa a profundidade do nexo pelo qual a vida intercruza o estado de problematização filosófica e assim, interpelando-nos de muitos modos, mas, sobretudo, na real urgência de pensar a solidão do homem moderno. A pergunta pelo outro, o lugar do encontro, o diálogo, a rua, a rotina, perpassa o que Giannini denomina arqueología de la experiencia. A rua está sempre à disposição, o ir-e-vir cotidiano é o lugar não só por onde circulamos, mas, sobretudo é o lugar de memórias. É o lugar que nos põe de frente ao outro, mas também diante de si mesmo.
Cinema e verdade: fundamentações para uma hermenêutica-fenomenológica dos filmes
Authors: Alves dos Santos Ribeiro Luan 
Published: June 2024

A presente investigação filosófica busca realizar questionamentos para a fundamentação de uma hermenêutica-fenomenológica dos filmes que o concebem no sentido de eventos da verdade ontológica, queremos dizer, da aletheia: verdade como aparecimento e concomitante ocultamento de significações. Para cumprir tal objetivo, primeiramente iremos opor a concepção da verdade tal como fundamentada por Heidegger à noção aristotélica de verdade correspondencial de modo a explicitar a dilatação da filosofia para além dos limites do discurso apofântico e caracterizar o cinema como poesia (Dichtung) que indica a tripla instituição (Stiftung) da verdade como doar (Schenken), como fundar (Gründen) e como iniciar (Anfangen) da história (Geschichte). Em nosso segundo momento, por sua vez, faremos considerações metodológicas a fim de consolidar o trato do cinema como um genuíno fenômeno (Phänomen) – não representação ou mimesis – e de delimitar nossa perspectiva interpretativa como alicerçada no dizer (léguen), que recolhe as suas fundamentações do discurso (lógos) da ontologia fundamental heideggeriana.

This study aimed to predict and optimize the porosity of Al6061 coatings using numerical simulation methods. The tasks to be solved are: to nest the multi-particle model established by the Python script in the CEL deposition model to simulate the cold spray deposition process. A multi-parameter function with particle temperature, substrate temperature, and particle velocity as independent variables and Al6061 coating porosity as dependent variables was established. The response surface analysis method was used to predict the optimal spraying parameters and coating porosity of Al6061 coating. The methods used are as follows: optimize the porosity of the coating through multi-factor coupling through response surface analysis; use a multi-particle model established through a Python script to be nested in the CEL deposition model to simulate the deposition process of cold-sprayed Al6061 multi-particles. To characterize the coating porosity more accurately, the average value of multiple groups of samples was taken as the final coating porosity value. Conclusions. the porosity value of Al6061 coating obtained by the prediction model is 1.969%; Under the influence of multi-factor coupling, particle velocity has the greatest impact on the porosity of the Al6061 coating, and the substrate temperature has the least impact. Optimum spraying parameters: particle temperature 649.692K, substrate temperature 536.437K, and particle velocity 672.385m/s. Under the optimal spraying parameters, the porosity value of the Al6061 coating is 1.91875%; The error between the predicted value and the actual value obtained by numerical simulation is only 2.55%.

Published: June 2024

Background: This study investigates the prevalence and characteristics of E. coli resistance patterns, focusing on isolates from patients with urinary tract infections (UTIs), diarrheal illnesses, and healthy controls. Methods: The study collected and identified E. coli isolates from 36 individuals: 17 with UTIs (urine samples), 6 with diarrhea (stool samples), and 13 healthy controls (stool samples). Antimicrobial susceptibility testing (AST) was performed to assess resistance against ten antibiotics from eight classes. Fluoroquinolone resistance was further evaluated against four drugs (nalidixic acid, ciprofloxacin, ofloxacin, and moxifloxacin). Additionally, molecular analysis of quinolone resistance-determining regions (QRDRs) in gyrA, gyrB, parC, and parE genes was performed on two selected isolates (U44 and U46) by genome sequencing. Results: Chloramphenicol and meropenem displayed the highest efficacy (>70% sensitivity), while AZM, AML, NA and SXT showed the highest resistance. UTI isolates exhibited higher resistance than diarrheal and healthy control counterparts. Worryingly, 58% of isolates exhibited multidrug resistance (MDR), with most (13/21) originating from UTI patients. The presence of MDR E. coli in five healthy individuals suggests potential carriage and community transmission. Fluoroquinolone resistance was particularly alarming, with moxifloxacin showing the highest resistance (80.95%). Molecular analysis confirmed mutations in all three fluoroquinolone resistance determining genes except gyrB. S84L and D87N dual mutations in the QRDR of gyrA was found in both isolates. S80I and S458A single mutations were observed in parC and parE, respectively. Conclusion: The study findings highlight the widespread prevalence of antibiotic resistance in E. coli and the urgent need for alternative treatment strategies.

Background: More than 200 viruses can cause respiratory tract infections. It is clinically indistinguishable to differentiate SARS-CoV-2 viral infections from other viruses that cause flu-like symptoms. This study was done to determine the infection and co-infection patterns of common respiratory tract viruses in patients with flu-like symptoms attending a fever clinic during the COVID-19 pandemic.
Methods: A total of 288 participants attending the Fever Clinic of Bangabandhu Sheikh Mujib Medical University having respiratory symptoms were enrolled in this cross-sectional study done from November 2021 to March 2022. Nasopharyngeal swabs were obtained for molecular detection of selected respiratory viruses by multiplex polymerase chain reaction.
Results: The study participants were aged 18 to 72 (mean 33.2) years. SARS-CoV-2 infection was 16.7% among the participants, while other respiratory viruses were 24.3% that included rhinovirus (14.6%) followed by adenovirus (5.6%) and parainfluenza viruses (3.5%). SARS CoV-2 and rhinovirus (29.4%), adenovirus and rhinovirus (23.5%), and rhinovirus and parainfluenza virus (17.6%) were the most common co-infections among them (n = 17).
Conclusion: Nearly 17% infections were caused by SARS-CoV-2. Rhinovirus infection was the second most common of other upper respiratory viral infections. There is also evidence of co-infections between SARS-CoV-2 and other common upper respiratory tract viruses.
