Objective

To assess test-retest reliability, construct validity, known groups discrimination, and responsiveness of the Assessment of the SpondyloArthritis international Society Health Index (ASAS HI) to evaluate functioning, disability, and health in patients with radiographic axial spondyloarthritis (r-axSpA).

Methods

Data were generated from 2 randomized, placebo-controlled, active-controlled phase III ixekizumab studies (COAST-V, N = 341; COAST-W, N = 316). Assessments included the following: test-retest reliability (ie, intraclass correlation coefficients [ICCs] between ASAS HI scores at screening and baseline), construct validity (ie, Spearman correlation with standard r-axSpA outcome measures), known groups discrimination (ie, 1-way ANOVA comparing the ASAS HI with different disease activity categories, measured by the Ankylosing Spondylitis Disease Activity Score [ASDAS]), and responsiveness (ie, Spearman correlation between changes in the ASAS HI and changes in the Bath Ankylosing Spondylitis Functional Index [BASFI], the Bath Ankylosing Spondylitis Disease Activity Index [BASDAI], the ASDAS, and the Patient Global Assessment [PtGA] as well as ANOVA comparing changes in the ASAS HI with various responder categories).

Results

The ICC for test-retest reliability was 0.78 for COAST-V and 0.76 for COAST-W, indicating adequate agreement. Moderate-to-large correlations (r= 0.40-0.61) were observed between the ASAS HI and the BASDAI. Statistically significant differences (allP< 0.001) between mean ASAS HI scores were observed for subgroups based on ASDAS-defined disease activity categories at baseline and week 16. Moderate-to-large correlations existed between changes in the ASAS HI and the BASFI, BASDAI, ASDAS, and PtGA from baseline to week 16. The ASAS HI differentiated statistically (P< 0.001) between ASAS, BASDAI, and ASDAS response groups.

Conclusion

The ASAS HI demonstrated reliability, construct validity, known groups discrimination, and responsiveness in adults with r-axSpA in 2 clinical trials.
The Effects of Continuity of Rheumatology Care on Emergency Department Utilization and Hospitalizations for Individuals With Early Rheumatoid Arthritis: A Population-Based Study
Authors: Davtyan Abel , Lee Jennifer J.Y. , Eder Lihi , Hawker Gillian A. , Luo Jin , Barber Claire E.H. , Thorne J. Carter , Widdifield Jessica
Published: February 2023

Objective

To determine if continuity of rheumatology care influences rates of emergency department (ED) visits and hospitalizations in patients with rheumatoid arthritis (RA).

Methods

A closed inception cohort of patients with RA diagnosed between 2000 and 2009 were followed until December 31, 2019. During the first 5 years following diagnosis, we categorized patients into 3 rheumatology care continuity groups (high, intermediate, and not retained in rheumatology care). Using a landmark analysis, we compared rates of ED visits and hospitalizations during follow-up. Multivariable Poisson regression models were used to estimate rate ratios (RRs), adjusting for demographics, comorbidities, and health services access and supply measures.

Results

The cohort included 38,528 patients, of which 57.7% (n = 22,221) were classified in the high rheumatology continuity group, 17.2% (n = 6636) were in the intermediate group, and 25.1% (n = 9671) were not retained in rheumatology care. Relative to the high continuity group, both the intermediate and nonretention groups had higher ED rates (RR 1.14, 95% CI 1.08-1.20, and RR 1.12, 95% CI 1.08-1.16, respectively). The intermediate group also experienced higher adjusted hospitalization rates (207.4, 95% CI 203.0-211.8 per 1000 person-years [PY]) than the high continuity group (193.5, 95% CI 191.4-195.6 per 1000 PY).

Conclusion

Patients with RA with higher continuity of rheumatology care had lower rates of ED visits and hospitalizations compared to those who did not receive continuous rheumatology care during the first 5 years of follow-up. These findings provide evidence to support the value of early and continuous rheumatology care for reducing hospitalizations and ED visits.

« Sentio ergo sum » : le chiffre cartésien du sens illatif chez John Henry Newman
Authors: Solari Grégory
Published: February 2023

Le Journal philosophique de John Henry Newman propose une figure « pathique » du Cogito cartésien. « Je pense donc je suis » doit s’entendre non comme la conséquence du fait de penser mais comme la dispense du mode de penser reposant sur l’inférence. Dans la lecture de Newman, cette dispense se traduit par la « suspension » de ergo dans le cogito . «  Cogito ergo sum  » devient «  sentio ergo sum  » – « je sens donc je suis ». L’épistémologie de Newman fait fond sur une affection. C’est l’esprit ( noûs ) qui « sent ». Une auto-affection atteste immédiatement l’existence du moi : c’est le cogito quand il est compris comme sentio , sentir. Une hétéro-affection atteste l’existence de Dieu : c’est la conscience comme phénomène ressenti à la limite de l’immanence.
« Newman vous mettra à l’aise ». Réflexions sur une invitation faite à Bergson
Authors: Waterlot Ghislain
Published: February 2023

Avec la publication des Deux Sources de la morale et de la religion , il apparut que Bergson s’était très fortement rapproché du christianisme. Allait-il se convertir au catholicisme ? La question était posée. Ses amis catholiques lui ont conseillé la lecture du cardinal Newman, en tant qu’auteur d’une pensée qui, introduisant la notion de « développement » du dogme, pouvait l’incliner à reconnaître une compatibilité de sa philosophie avec la théologie catholique telle qu’elle se comprenait désormais et lever ainsi les obstacles mis sur le chemin par la « crise moderniste ». Cet essai tend à montrer que les difficultés étaient plus profondes que ne le pensaient les amis de Bergson, dans la mesure où le rapport entre le dogme et la vérité n’est en fait pas pensé de la même façon chez le cardinal britannique et chez le philosophe français.
« Lumière réflexe » et « sens illatif » : John Henry Newman et la Grammaire de l’assentiment
Authors: Rabourdin David
Published: February 2023

Dans la Grammaire de l’assentiment , lors de son investigation des facultés humaines et de leur jeu dans la recherche de la vérité, Newman se place sous l’éclairage d’une « lumière réflexe », qui lui permet d’affirmer le « sens illatif » comme unique lien entre inférence et assentiment. Cette « lumière » introduit une perspective théologique au cœur de son investigation philosophique. Ainsi, Newman affirme à la fois le dynamisme de l’esprit humain dans son chemin vers la vérité, le caractère libre et personnel de ce chemin, et la présence de la Providence divine à chaque étape de cette recherche.
Sentence matrimoniale pro nullitate erronée et secondes noces canoniques : un apax juridique à la suite de la faculté II du 11 février 2013
Authors: Danto Ludovic
Published: February 2023

Le mariage jouit de la faveur du droit. Tout mariage est indissoluble et seule la fin de celui-ci permet de passer à de secondes noces. Dans le cas contraire, tout consentement est naturellement suffisant mais juridiquement inefficace. Or, les facultés du 11 février 2013 concédées à la Rote romaine par le pape Benoît XVI remettent en cause ce principe : il est possible de reconnaître des secondes noces malgré l’éventuel empêchement de lien préexistant. La position catholique rejoindrait par cet apax juridique la position orthodoxe.
Spacelike ruled surfaces with stationary Disteli-axis
Authors: Mofarreh Fatemah , Abdel-Baky Rashad A.
Published: February 2023

This paper derives the expressions for spacelike ruled surfaces with stationary Disteli-axis by means of the E. Study map. This provides the ability to compute a set of Lorentzian curvature functions which define the local shape of spacelike ruled surfaces. Consequently, some well-known formulae of surface theory at Lorentzian line space and their geometrical explanations are obtained and examined. Lastly, a characterization for a spacelike line trajectory to be a constant Disteli-axis is derived and investigated in detail.
Controllability and observability of discretized satellite magnetic attitude control system
Authors: Liu Sihui , Huang Qingdao
Published: February 2023

In this paper, two different discrete schemes of the second-order linear time-varying system represented by the linearized satellite magnetic attitude control motion equation are obtained by Euler method. Then, the controllability and observability conditions of a new discrete second-order linear time-varying system are proposed and the validity of these conditions is further verified by some numerical examples. Next, the theoretical results are applied to investigate the controllability and observability of the discretized satellite magnetic control system. Different periods $ \tau $ are chosen to investigate the effect on the controllability and observability of the resulting discrete system. The corresponding conclusions are obtained.
Immersed finite element methods for convection diffusion equations
Authors: Jo Gwanghyun , Kwak Do Y.
Published: February 2023

In this work, we develop two IFEMs for convection-diffusion equations with interfaces. We first define bilinear forms by adding judiciously defined convection-related line integrals. By establishing Gårding's inequality, we prove the optimal error estimates both in $ L^2 $ and $ H^1 $-norms. The second method is devoted to the convection-dominated case, where test functions are piecewise constant functions on vertex-associated control volumes. We accompany the so-called upwinding concepts to make the control-volume based IFEM robust to the magnitude of convection terms. The $ H^1 $ optimal error estimate is proven for control-volume based IFEM. We document numerical experiments which confirm the analysis.
Control and elimination in an SEIR model for the disease dynamics of COVID-19 with vaccination
Authors: Witbooi Peter Joseph , Vyambwera Sibaliwe Maku , Nsuami Mozart Umba
Published: February 2023

COVID-19 has become a serious pandemic affecting many countries around the world since it was discovered in 2019. In this research, we present a compartmental model in ordinary differential equations for COVID-19 with vaccination, inflow of infected and a generalized contact rate. Existence of a unique global positive solution of the model is proved, followed by stability analysis of the equilibrium points. A control problem is presented, with vaccination as well as reduction of the contact rate by way of education, law enforcement or lockdown. In the last section, we use numerical simulations with data applicable to South Africa, for supporting our theoretical results. The model and application illustrate the interesting manner in which a diseased population can be perturbed from within itself.
Revistas científicas de Comunicación en España: prospectiva sobre su gestión y sostenibilidad económica
Authors: Baladrón-Pazos Antonio J. , Correyero-Ruiz Beatriz
Published: February 2023

En este artículo se realiza una prospectiva a diez años sobre la evolución de las revistas científicas de Comunicación en España; en concreto, abordando los retos a los que se enfrentarán para garantizar su sostenibilidad económica y las medidas que adoptarán en este sentido respecto a sus fuentes de financiación, su organización interna y las características de su producto editorial. Para ello, se realizó un estudio Delphi en el que participaron 28 editores de las principales cabeceras. Los resultados evidencian que persistirán los problemas de financiación y el insuficiente apoyo de las instituciones editoras, pese a lo cual el papel de la financiación privada seguirá siendo minoritario. Estos problemas dificultarán la competitividad de las revistas en el contexto de la edición científica internacional, por lo que implementarán medidas para intentar corregirlos, tales como potenciar la digitalización efectiva o el refuerzo y valoración de los equipos editoriales.

Awake Prone Positioning in Nonintubated Patients With Acute Hypoxemic Respiratory Failure
Authors: Fusi Cristian , Bulleri Enrico , Villa Michele , Pisani Luigi , El Aoufy Khadija , Lucchini Alberto , Bambi Stefano
Published: February 2023

Background

Awake prone positioning research focuses primarily on improving oxygenation and reducing intubation and mortality rates. Secondary outcomes concerning patient safety have been poorly addressed.

Objective

To summarize current evidence on the frequency of adverse events during awake prone positioning and the effects on patients’ safety, comfort, and tolerance.

Methods

This scoping review used the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews. MEDLINE/PubMed and CINAHL databases were the primary sources for the systematic search.

Results

The review included 19 original studies involving 949 patients who underwent awake prone positioning. No major complications such as death, severe respiratory compromise, or hemodynamic disease were reported. Ten studies reported the following secondary adverse events related to awake prone positioning: skin breakdown (1%-6% of patients), pain (12%-42%), discomfort (35%-43%), vomiting (2%-7%), intolerance (3%-47%), and vascular catheter dislodgment (5%). The duration of awake prone positioning sessions varied widely (0.3-19 hours). Seven studies reported that nurses helped patients during prone positioning maneuvers, including monitoring and surveillance, and 3 studies reported patients placing themselves in the prone position. In 6 studies light or moderate sedation was employed in the procedures.

Conclusions

Awake prone positioning was not related to cardiorespiratory consequences but was associated with pain, intolerance, discomfort, and patients’ refusal. Patients should receive education regarding awake prone positioning to improve their acceptance. Health care professionals should optimize pain control, communication, patient comfort, patient adherence, and correct positioning.
Paroxysmal Sympathetic Hyperactivity After Acquired Brain Injury: An Integrative Literature Review
Authors: Seo WhaSook
Published: February 2023

Background

Paroxysmal sympathetic hyperactivity may occur in patients with acute brain injury and is associated with physical disability, poor clinical outcomes, prolonged hospitalization, and higher health care costs.

Objective

To comprehensively review current literature and provide information about paroxysmal sympathetic hyperactivity for nurses.

Methods

An integrative literature review was conducted according to Whittemore and Knafl’s method. The search was conducted from October 2020 through January 2021. The main targets of the literature search were definition, incidence rate, causes, clinical characteristics, pathophysiology, diagnosis, and treatment of paroxysmal sympathetic hyperactivity in pediatric and adult patients. The results were reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results

The most characteristic clinical features of paroxysmal sympathetic hyperactivity are hypertension, tachycardia, tachypnea, hyperthermia, diaphoresis, and abnormal motor posturing. Reported incidence rates of paroxysmal sympathetic hyperactivity in patients with brain injury range from 8% to 33%. Various diagnostic criteria have been proposed; most are based on clinical symptoms. Ruling out other causes of the signs and symptoms of paroxysmal sympathetic hyperactivity is important because the signs and symptoms are nonspecific. The major goals of paroxysmal sympathetic hyperactivity management are avoidance of stimuli that may trigger a paroxysmal episode, inhibition of sympathetic overactivity, and prevention of damage to other organs.

Conclusions

Critical care nurses should be aware of the signs and symptoms of paroxysmal sympathetic hyperactivity in patients with acute brain injury. Early identification is important to ensure timely treatment for patients with paroxysmal sympathetic hyperactivity.
MicroRNAs in Macrophages: Regulators of Activation and Function
Authors: Sprenkle Neil T , Serezani C Henrique , Pua Heather H
Published: February 2023

Macrophages are sentinels of the innate immune system that maintain tissue homeostasis and contribute to inflammatory responses. Their broad scope of action depends on both functional heterogeneity and plasticity. Small noncoding RNAs called microRNAs (miRNAs) contribute to macrophage function as post-transcriptional inhibitors of target gene networks. Genetic and pharmacologic studies have uncovered genes regulated by miRNAs that control macrophage cellular programming and macrophage-driven pathology. miRNAs control proinflammatory M1-like activation, immunoregulatory M2-like macrophage activation, and emerging macrophage functions in metabolic disease and innate immune memory. Understanding the gene networks regulated by individual miRNAs enhances our understanding of the spectrum of macrophage function at steady state and during responses to injury or pathogen invasion, with the potential to develop miRNA-based therapies. This review aims to consolidate past and current studies investigating the complexity of the miRNA interactome to provide the reader with a mechanistic view of how miRNAs shape macrophage behavior.
Diagnostic value of LungPoint navigation combined with EBUS-GS & ROSE in peripheral pulmonary nodules
Authors: Zhang Qun-Cheng , Xuan Wei-Xia , Li Hui-Li , Sun Guan-Nan , Cheng Dong-Jun , Wang Zheng , Yong-Qi  , Zhang Xiao-Ju
Published: February 2023

Background & objectives:

Recently, there has been a surge to develop new devices and techniques for the diagnosis of peripheral pulmonary lesions such as the combination of LungPoint navigation and endobronchial ultrasound with a guide sheath (EBUS-GS). The present study aimed to explore the diagnostic value of LungPoint navigation in combination with EBUS-GS and rapid on-site evaluation (ROSE) particularly for peripheral pulmonary nodules.

Methods:

Patients (n=108) with pulmonary nodules (10 mm ≤ nodal diameter ≤30 mm) presenting to Henan Provincial People’s Hospital were detected using chest computed tomographic (CT) scanning and bronchoscopy. All patients were evaluated using LungPoint navigation, EBUS-GS and ROSE techniques to evaluate the positive rate of combined diagnosis using the three methods.

Results:

A total of 108 patients participated in this study and successfully underwent all the three procedures. Of these, 82 patients were accurately diagnosed, making the overall diagnostic rate of 75.9 per cent for combined LungPoint navigation, EBUS-GS, and ROSE analyses. Further subgroup analysis of the diagnostic rate of the three combined techniques were conducted based on the size of the nodules which showed a diagnostic rate of 65.3 per cent for 10 mm ≤ nodule diameter ≤20 mm and 85.7 per cent for 20 mm ≤ nodal diameter ≤30 mm. Of the 108 patients, 85 had solid nodules and 23 had ground-glass nodules; the positive rate of diagnosis of solid nodules was the highest. The patients ultimately were diagnosed with lung cancer with a positive rate of 83.5 per cent. The sensitivity, specificity and positive and negative predicted values for ROSE were 90.3, 78.3, 84.8 and 83.6 per cent, respectively.

Interpretation & conclusions:

The combined use of the three techniques can effectively shorten the duration of the total diagnosis period and improve the safety of diagnosis without affecting the detection rate.

Published: February 2023

Background and Aim:

To determine the utilization of eye care services in an underserved community in Enugu State, Nigeria.

Materials and Methods:

A community-based cross-sectional study was conducted among adults aged 18 years and older. A structured questionnaire was used to collect information on the utilization of eye care services within the last two years.

Result:

A total of 500 adults with a mean age of 48 ± 10 years participated in the study, the majority (65.6%) of whom were females. The utilization rate within the last two years was 18% (40/500). Utilization of eye care services was associated with age, religion, occupation, marital status, monthly income, education, family history, and history of ocular disease (all P < 0.05). The major barrier to the utilization of eye care services was cost (30%), distance (22.6%), and bad road infrastructure (15.2%).

Conclusion:

There is a low rate of eye care service utilization in the Ugbawka community of Enugu State, Nigeria. The cost of eye care services, distance, and bad road infrastructure were the major barriers to the use of eye care services. These suggest the need for the provision of affordable and accessible eye care services in this community to reduce the burden of visual impairment and blindness.
A Rare Case of Abdominal Cocoon Associated with Internal Hernia in an Adult
Authors: Kumar N , Katragadda S , Mallik D , Dhamala I , Basu S
Published: February 2023

A transmesenteric internal hernia (TIH) is a protrusion of a viscus through the mesenteric defect. It is secondary to previous gastrointestinal surgery in an adult. Early diagnosis and management are warranted to prevent the strangulation of the bowel in a TIH. Here, we are reporting a case of a 24-year-old gentleman with COVID-positive status who has presented with cough, abdominal cocoon, and features of subacute intestinal obstruction (SAIO) without any previous history of abdominal surgery. A nonoperative trial is given in the management of abdominal cocoon with SAIO. In contrast, delay in surgical intervention in TIH leads to bowel gangrene. Surprisingly even on contrast-enhanced computed tomography of the abdomen, TIH was not picked up. We have diagnosed this case intraoperatively with gangrene of the bowel. In an abdominal cocoon without any history suggestive of tuberculosis or previous surgery, or any other condition that leads to an intra-abdominal reaction, an internal hernia should be kept as a differential diagnosis. The delay in diagnosis and surgical intervention is associated with potentially disastrous complications.
Impact of Different Intraorifice Barriers on Fracture Resistance of Non-Vital Bleached Teeth
Authors: Abduljalil M , Sakalli B , Basmaci F
Published: February 2023

Background and Aim:

This study aimed to evaluate the effects of bleaching agents on the fracture resistance of endodontically treated teeth using different intraorifice barrier (IOB) materials.

Materials and Methods:

The endodontic treatment was performed for 160 mandibular premolars, and then, the teeth were divided into four groups according to the IOB: Ionoseal, Biodentine, ProRoot MTA, and TheraBase. Then, these teeth were subdivided into four subgroups (n = 10) based on the bleaching agents as distilled water (control), hydrogen peroxide 35% (HP), sodium perborate (SP), and carbamide peroxide 37% (CP). The access cavities were restored with composite resin after applying the bleaching agents for 7 days. The fracture resistance test was performed using a universal testing machine. Data were statistically analyzed, and the significance level was set at 5%. A scanning electron microscope was used to evaluate the effect of bleaching agents on the surfaces of IOBs.

Results:

The highest fracture resistance values were observed in Biodentine groups with significant differences compared to Ionoseal and ProRoot MTA (P <.05). The distilled water groups showed significantly the highest fracture resistance compared to SP and HP groups (P <.05). There was no significant difference between SP, HP, and CP groups (P >.05). It was demonstrated that the morphological surface of the intact IOBs (control) was different from the surface of IOBs treated with bleaching agents.

Conclusion:

The intracoronal bleaching procedures affected negatively the fracture resistance of the endodontically treated teeth.

Published: February 2023

In this article, we reported a rare case of nine syndrome, which is characterized by clinical signs of the one-and-a-half syndrome, ipsilateral facial palsy, contralateral hemiparesis, hemihypesthesia, or ataxia. A 44-year-old male presented with sudden onset of double vision for 3 days. Examination revealed left horizontal gaze palsy, internuclear ophthalmoplegia, left lower motor neuron facial nerve palsy with right hemiplegia, and hemihypesthesia. Magnetic resonance imaging brain showed evidence of acute infarction at the left paramedian pons. Magnetic resonance angiography revealed a beaded small-caliber basilar artery suggestive of intracranial vasculopathy in the posterior circulation. The patient has been treated with an antiplatelet and lipid-lowering agent. His right hemiparesis has improved, but the ocular motility and left facial paresis persisted. The literature reviews of 14 cases of nine syndrome were discussed, and the biography background, clinical pictures, etiology, neuroimaging, treatment, and recovery status were described.
Shin Chan, un compendio de contravalores
Authors: Fernández Obregón Francisco Javier
Published: February 2023

El dibujante de cómics Yoshito Usui imaginó y creó a Shin Chan a finales de los 80 y principio de los 90. En 1991 comenzó a publicar una tira cómica en un pequeño periódico japonés en la que pretendía desmitificar la imagen del ama de casa a través de un niño de 5 años y sufamilia. El éxito fue inmediato y la crítica social y el humor del cómic se extendió. Pronto empezó a publicar álbumes de cómics de Shin Chan quetuvieron una gran acogida. Con este repentino éxito no tardarían en llegar los responsables de TV Asahi para proponer a Usui dar el gran paso: llevar a Shin Chan del papel a la televisión en forma de serie animada. En 1992 empezó a emitirse Shin Chan en Japón, llevando a la pantalla las mismas historias del cómic, aunque los responsables de TV Asahi pidieron a Usui que suavizara sus contenidos porque era posible que también atrajera al público infantil, a pesar de que la serie fue concebida para un público adulto. Pero por mucho que se suavizara, Shin Chan revolucionó y creó polémica en Japón, no por los aspectos que hoy se enfatizan en Occidente, ya que la sexualidad y la irreverencia en los dibujos animados no es algo nuevo para los japoneses, sino porque en cierta manera se burlaba de las estrictas y serias costumbres niponas.

This study aimed to assess the economic and engineering feasibility of a large-scale biodiesel manufacturing operation from edible oil waste. The edible oil model used for economic analysis in this study is palm oil waste. Several economic parameters (i.e., gross profit margin (GPM), payback period (PBP), break-even point (BEP), cumulative net present value (CNPV), profitability index (PI)), and internal rate return (IRR) were examined to inform the potential production of biodiesel from edible oil waste in ideal condition. To confirm the feasibility of a manufacturing project, the project is estimated from ideal to worst-case conditions in production activities such as analysis of changing raw material, labor, tax, utility, and selling price costs. Based on an engineering perspective, the result indicated that biodiesel production from edible and non-edible oil is feasible. From an economic perspective, economic analysis shows that biodiesel production from edible oil waste is promising because the economic parameters as analyzed show positive results. Our findings are expected to provide an industrial-scale picture of economic evaluation and layout, particularly in the production of biodiesel, which is commonly used as a renewable energy source for fuel in trucks, trains, ships, and barges.
A proof system for graph (non)-isomorphism verification
Authors: Banković Milan , Drecun Ivan , Marić Filip
Published: February 2023

In order to apply canonical labelling of graphs and isomorphism checking in
interactive theorem provers, these checking algorithms must either be
mechanically verified or their results must be verifiable by independent
checkers. We analyze a state-of-the-art algorithm for canonical labelling of
graphs (described by McKay and Piperno) and formulate it in terms of a formal
proof system. We provide an implementation that can export a proof that the
obtained graph is the canonical form of a given graph. Such proofs are then
verified by our independent checker and can be used to confirm that two given
graphs are not isomorphic.

Probe permeameter (also known as Mini-permeameter) has been widely used in many field and laboratory applications where in-situ measurements and spatial distributions of permeability are needed. Mini-permeameter measurements have become popular techniques for collecting localized permeability measurements in both laboratory and field applications. It is designed to obtain fast, cheap, intensive and non-destructive permeability measurements and to describe the spatial arrangement of permeability. Currently the probe permeability meter is designed and manufactured as a portable air permeability for field applications and to be used in outcrop and core samples. In this instrument, the permeability is measured by air that flows from the samples to be measured into an air chamber through the vacuum created by increasing the volume of the chamber. In carbonate reservoirs, permeability predicted from pure porosity-permeability empirical relationship is often difficult due to complex rock pore systems leading to poor porosity-permeability relations. Once the relationships between permeability and textural rock properties are clearly established in carbonates, they can provide better permeability predictions from porosity data. Rock texture is an important parameter for the understanding of the porosity and permeability characteristics of carbonate reservoirs. In addition to predicting carbonate rock facies from routine core plug porosity and permeability measurements, there is an approach to determine carbonate reservoir facies based on core-plug probe permeability. The results of the probe permeability measurements, in this paper, can be used in combination with the porosity values derived from the well logs to classify and predict rock facies in carbonate cored or uncored reservoirs in Phu Khanh basin.

Understanding the permeability-porosity relationships is the key to improving reservoir prediction and exploitation especially in carbonate reservoirs, which are known for their complex textural and diagenetic variation. Rock type classifications have long been proven to be an effective technique for establishing permeability- porosity relationships, enhance the capability to capture the various reservoir flow behavior and prediction for uncored reservoir zones. This study highlights some of those practical and theoretically-correct methods, such as Hydraulic Flow Unit (HFU); Global hydraulic element (GHE), Winland’s R35 method, Pittman method, Lucia method. They are proposed and tested for identification and characterization of the rock types using a database of 555 core plugs from the Miocene carbonate reservoir in the Nam Con Son basin. It is a large isolated carbonate build-up structure which were deposited within a shallow marine platform interior and are dominated by coral, red algal and foraminiferal packstones, wackestones and grainstones. Hydrocarbons in this reservoir have been found in the upper most part of the late Miocene formation. Conventional core data were first used to define and display the cross plot of permeability and porosity. Different charts and cutoff thresholds were used to classified, defined number of rock type and the linear and non-linear equations were established. The predicted core permeability was calculated using different methods and compared with the actual core permeability for each rock type. The predicted reservoir rock type and permeability predictions of HFU method was recognized to give better matching of measured core permeability with coefficient of more than 89%.

Fault transmissibility multipliers are a simple way of accounting for the effects of faults on fluid flow across fault plans in history matching of production simulation models. Fault transmissibility multipliers can be calculated using parameters such as fault clay, fault smear, thickness, and permeability. In this study, three emperical methods given by Manzocchi et al. (1999), Jolley et al. (2007), and Sperrevik et al. (2002) have been applied to the Oligocene sandstone reservoir, Tay Ho Field. The Oligocene reservoir is a complicated sandstone that was deposited in alluvial-fluvial and lacustrine environments, trapped by both stratigraphic and structural types, sandbody isolated by multi-activated faults. Fault sealing is one of the key factors controlling hydrocarbon accumulations and trap volume and can have a significant influence on reservoir performance during production. Furthermore, the prospective of structural or combination traps in stacked clastic reservoir settings that are typically found in many of the known hydrocarbon provinces in the Cuu Long basin, often critically hinges on the presence of a working fault side seal. Based on a thorough understanding of the key controls on fault seal risk and retention capacity, a consistent methodology to access these factors across a prospect portfolio is essential to achieve a balanced prospect ranking and an accurate assessment of prospect success volumes. In the process workflow built by PVEP Blocks 01/97 & 02/97, the assessment of fault seal capacity and compartmentalization in the Oligocene reservoir have been incorperated by using fault deformation, displacement, juxtaposition, fault zone thickness, shale gouge ratio (SGR), shale smear factor (SSF), clay smear potential (CSP), fault thickness and permeability. In our research, the Sperrevik et al. (2002) method provides the best historical match and most logical geological evidence; thus, it shall be used for dynamic models and further studies.

In fields with increasing water cut and depleting reservoir energy, Electric Submersible Pump (ESP) installation is a sustainable production option. It helps to extend life of the wells by lower abandonment pressure and therefore increases the recovery factor. In addition, the gas lift saving from ESP conversion wells could be utilized to optimize others wells’ productivity thus boosting the total field production. Over the last 9 years, Cuu Long JOC has been conducted 5 ESP campaigns in fractured granitic basement reservoirs which bringing full of surprises. The selected field for ESP pilot was brought on production initially in 2008 with over 75,000 bopd. However, water breakthrough occurred after 8 months quickly reduced the total field production to 5,000 bopd in 2013. At the time of ESP conversion, gas lift have already optimized and it is not sufficient to maintain the rate as most of wells flowed with 95% water cut. With ESP application, the wells were able to reach 12,000 blpd and reduce the water cut not only for itself but also for adjacent wells. Despite the pump average run life is not meet the expectation, ESP application shows better efficiency in term of oil production compared to gas lift under the same reservoir conditions. This paper summarizes a process of ESP application in high temperature environment including candidate selection, ESP design and actual production performance. The learning and experience developed from 11 ESPs installation provide an insight about the potential of ESP use for oil production in fractured basement reservoir.
