Abstract
The oil and gas industry during drilling operations constantly seeks to lower cost and improve efficiency without compromising on safety. Planning a well before commencing drilling operations is an important process that helps to cut down on cost. Planning enables the driller to analyse various potential problems and find mitigation techniques so that the drilling operation is optimised. Manual technique of planning a well is not able to effectively anticipate certain drilling problems, translating to an increased cost of drilling. Seeking transformation over the years has resulted in looking towards data-driven solutions. This paper focuses on developing a digital copy of the directional drilling process to plan a well. Twin digitalisation was used to translate a drilling process into a virtual environment. This involved the use of physics-based models, mathematical models, and programming languages. The system gives an optimal plan with focus on safety, risk reduction, and improved performance. In addition, the system provides "what-if" scenarios, which allow detection of potential problems before actual drilling operations commence. In summary, digital twin was found to be advantageous over the manual technique by playing one of the greatest roles in combining digital and real-time data together with predictive diagnostic messages, leading to an improved accuracy rate in decision making and results.

Abstract
Devotion of quality time, effort, and dedicated resources during the planning phase of frac or extension packed wells and establishing a clear communication path to a collaborative execution, will ensure the achievement of a successful stimulation with a reliable sand control. These diligent planning efforts become more crucial when faced with challenging thrust fault environments which can adversely affect the outcome of a frac or extension packs. Thrust faults traversing a target reservoir needs to be carefully evaluated for activation or uncontrollable fluid loss during the frac pack process to ensure adequate mitigation can be implemented for a successful job.
This paper illustrates the systematic approach used to optimize sand control and productivity for a deepwater well including the following challenges that were encountered: TCP overbalance concerns, brine density, and the need to manage potential high fluid losses in a depleted zone (hydrostatic pressure less than 80 psi below estimated fracture pressure). Fracpack was designed without any frac length constraint. Gel concentration, pad volume and pump rate were maximized to manage low fluid efficiency. The job was pumped as per design with hard screenout at nominal rate, 70% of proppant placed behind casing and good annular pack.
The well in question was an oil producer which was drilled with the wellbore crossing the main thrust fault at the reservoir level. It was drilled with no wellbore stability issues reported. The sand-face completion presented major challenges as summarized below. Lower Zone: short perforation interval that was 25 ft above the OWC and less than 80 ft away from the main thrust fault. Middle Zone: depleted sands with the main thrust fault crossing the wellbore few feet above the top perforation (top of the reservoir sand). Upper Zone: thrust fault was less than 90 ft away from the wellbore.

Abstract
Engineering a gas field that is more than 15 years old comes with its own challenges especially when there is a need to redesign production rules to meet Management objective functions based on the current need of the Company. The basic requirement is to continually Demonstrate commitment to Nigerian environmental stewardship while optimizing every other objective functions. This paper reviews the performance of a Gas field taking into cognizance the dynamics of operational needs and challenges encountered in the daily operations and provides solution.
An Integrated Production model sensitive to thermodynamic conditions was developed to interpret daily operations to Production Engineering which formed a framework to forecast future production. The model also characterizes flow in the pipe and predicts daily fluid (gas and oil) production. Additionally, the model enables investigation of Flow Assurance (hydrate formation, Pipeline Corrosion, Pipeline Erosion etc.) and integrity of subsurface safety valves to ensure uninterrupted flow. Interconversion of hydrocarbon gas to Liquid is then reviewed in the model before execution.
Results from the Integrated production model were used to investigate historical events (well trips, facilities shut in etc.) and advise on how best to prevent such emergencies. Planning with this model enables striking a balance between Condensate needs versus gas production targets given the Economics of production and funds within the Environmental design. Reoccurring Flow Assurance and Well integrity challenges were flagged to be addressed and eliminated. A total gain of about 20 MMSCFD and 1,000 BPD of condensate was achieved with options to re line network arrangement to improve results.

Abstract
Natural gas has been widely touted as a transition fuel due to its lower greenhouse gas emissions when compared to other fossil fuels such as coal and oil, serving as a bridge fuel between the fossil fuels and the renewables. This has made gas condensate reservoirs (GCRs) a crucial resource in meeting the increasing demand for cleaner, more affordable energy for the energy transition.
GCRs while producing gas also deliver valuable condensate liquid that could pose production challenges. An example is condensate banking around the wellbore which reduces overall well productivity. Furthermore, GCRs also require more rigorous pressure-volume-temperature (PVT) modeling to cover the producing lifecycle of the reservoir and understand how much of the condensate will be produced to the surface.
Resolving these additional complexities with GCRs requires proper surveillance data acquisition, PVT analysis, reservoir simulation to improve reservoir understanding and integrated asset models to bring all the knowledge together and capture flow interactions. Data such as fluid lab tests, reservoir pressure trend, pressure transient testing and production tests are analyzed; giving insights into fluid, reservoir, and near-wellbore properties. Gas wells are typically online for extended periods to meet daily contract quantities (DCQ). This poses a challenge to the acceptable duration of pressure build-up (PBU) tests. For this, a review of some opportunistic extended build-up tests that were done during a scheduled Turn-Around Maintenance that allowed a deeper radius of investigation into the reservoirs is presented.
This text builds on existing literature on the management of gas condensate reservoirs highlighting lessons learnt and best practices while using case studies from some Niger Delta reservoirs. The case studies presented cover a wide range of some reservoir parameters that impact expected ultimate recovery such as permeability and condensate-gas-ratio (CGR) while discussing field practices and results.

Abstract
Urban rivers are the origin of civilizations, the source of water supply, and the center of recreational and sports activities. The role of rivers can be investigated from various political, cultural, security, drought, economic, and health aspects. This study was conducted in order to identify the influencing components of urban rivers on ecosystem sustainability. The weight coefficients of climatic, social, economic, and ecological components were evaluated through dynamic cluster analysis, and their role in ecosystem sustainability was quantified. In addition, the relationship between water-based factors and environmental components was determined in finding the best components of river ecosystem evaluation for future decisions. The provided analysis can increase the stability of the urban river ecosystem and can rank the priority of the impact factors. Ecological environment statistics, nature measures, economic parameters, and land cover rate substantially affected the visual influence of the urban river ecosystem. Results showed that the proposed evaluation provided a reasonable framework to evaluate the sustainability of the urban river ecosystem and visual perception to improve the design efficiency by decision-makers.

Abstract

In the process of sanitizing drinking water, humic acid present in drinking water sources reacts with chlorine disinfectant and forms mutagenic, defective, and carcinogenic disinfection byproducts such as trihalomethanes and haloacetic acids. In the present study, the methanolic extract of Elaeagnus angustifolia tree bark was used for the synthesis of ZnFe2O4@TiO2 nanocomposite and then properties and structural elements and diagnostic features of nanoparticles were analyzed. According to the results, the ZnFe2O4@TiO2 nanocomposites have an average crystalline size of ∼65–250 nm. Also, the effects of pH (3–11), nanoparticle dose (0.005–0.1 g/L), and humic acid concentration (2–15 mg/L) were examined up to 120 min of time. From the results, the highest removal percentages achieved about 100% at optimal conditions (pH = 3, nanocomposite dose = 0.05 g/L and humic acid initial concentration = 2 mg/L). The results of this research showed that the efficiency of nanocomposite at the highest concentration of humic acid that was investigated in this research (15 mg/L) was about 95.67%. Therefore, it can be concluded that this nanocomposite, while being cost-effective and environmentally friendly, is also very effective in removing humic acid from an aqueous solution.

Abstract

Microcystins with leucine arginine (MC-LR) is a virulent hepatotoxin, which is commonly present in polluted water with its demethylated derivatives [Dha7] MC-LR. This study reported a low-cost molecularly imprinted polymer network-based electrochemical sensor for detecting MC-LR. The sensor was based on a three-dimensional conductive network composed of multi-walled carbon nanotubes (MWCNTs), graphene quantum dots (GQDs), and gold nanoparticles (AuNPs). The molecularly imprinted polymer was engineered by quantum chemical computation utilizing p-aminothiophenol (p-ATP) and methacrylic acid (MAA) as dual functional monomers and L-arginine as a segment template. The electrochemical reaction mechanism of MC-LR on the sensor was studied for the first time, which is an irreversible electrochemical oxidation reaction involving an electron and two protons, and is controlled by a mixed adsorption–diffusion mechanism. The sensor exhibited a great detection response to MC-LR in the linear range of 0.08–2 μg/L, and the limit of detection (LOD) is 0.0027 μg/L (S/N = 3). In addition, the recoveries of the total amount of MC-LR and [Dha7] MC-LR in the actual sample by the obtained sensor were in the range from 91.4 to 116.7%, which indicated its great potential for environmental detection.
A critical review on Samana Vayu apropos regulation of Gastrointestinal Tract
Authors: Tripathi Ritunanda , Shuchi Dubey  , N.K. Prasad  
Published: July 2023

Ayurveda believes in the theory that whatever is present, in the external universe is also present in the human body. Understanding the factors that constitute the body provides knowledge regarding the factors which are responsible for its well-being. The complete physiological action of the body can consolidate in Dosha, Dhatus, and Malas, these three are the main constituents of the body. The Tridoshas", control the fundamental physiological functions of the body. Vata being supreme among the three Doshas, conducts and controls all the activities of the body through Vayu. The Samana Vayu lies near the Jatharagni and its Sancharsthan (effective area) is Kostha; its function is Grahana, Pachana, Vivechana, and Munchana of Anna Dravya and providing strength to Agni. Prana, Samana, and Apana are three types of Vayu, that assist Jatharagni in the process of Anna Pachana. In modern science, a lot of research has been done regarding the factors participating in the regulation of the gastrointestinal tract such as enzymes, hormones, nerves, etc. However, the exact role of Samana Vayu in the regulation of Agni and consequent absorption of different food materials and metabolism followed by excretion, etc. is not properly understood in Ayurveda, leading to confusion between the functions of Samana Vayu, Pachaka Pitta, Kledaka Kapha and even up to the excretory functions of Apana Vayu. This study aims to understand the role of Samana Vayu in the physiology of Pachana through Agni and its regulatory mechanism.

Published: July 2023

Acharya Vagbhat quotes that loss of vision is a loss of life. Vision is our primary connection with this world. With the help of eyes, we can interact with our surroundings in more than a million ways every second. Computer, the knowledge bank of modern life, has emerged as a profession causing vision-related discomfort, ocular fatigue, and systemic effects. Computer Vision Syndrome (CVS) is the new nomenclature to the visual, ocular, and systemic symptoms arising due to the long time and improper working on the computer and is emerging as a pandemic in the 21st century. Approximately 60 million people suffer from Computer Vision Syndrome globally, which leads to a decrease in productivity at work and Quality of life. Ayurved being an ancient system of medicine has millions of remedies in it, which is useful for all types of disease, whether it is stated directly or not. Ayurved classics quote that if a physician is not able to get a direct description of the disease in Samhitas, he should not feel guilty about that and should treat the condition based on the involvement of Doshas in it. Hence, here an attempt has been made to provide an explanation of Dosha, Dushya & Samprapti of Computer vision syndrome according to Ayurveda.

Published: July 2023

Abstract

Background
The World Health Organization, the Centers for Disease Control and Prevention, and the Gerontological Society of America have made efforts to raise awareness on ageist language and propose appropriate terms to denote the older adult population. The COVID-19 pandemic and older adults’ vulnerability to the disease have perpetuated hostile ageist discourse on social media. This is an opportune time to understand the prevalence and use of ageist language and discuss the ways forward.

Objective
This study aimed to understand the prevalence and situated use of ageist terms on Twitter.

Methods
We collected 60.32 million tweets between March and July 2020 containing terms related to COVID-19. We then conducted a mixed methods study comprising a content analysis and a descriptive quantitative analysis.

Results
A total of 58,930 tweets contained the ageist terms “old people” or “elderly.” The more appropriate term “older adult” was found in 11,328 tweets. Twitter users used ageist terms (eg, “old people” and “elderly”) to criticize ageist messages (17/60, 28%), showing a lack of understanding of appropriate terms to describe older adults. Highly hostile ageist content against older adults came from tweets that contained the derogatory terms “old people” (22/30, 73%) or “elderly” (13/30, 43%).

Conclusions
The public discourse observed on Twitter shows a continued lack of understanding of appropriate terms to use when referring to older adults. Effort is needed to eliminate the perpetuation of ageist messages that challenge healthy aging. Our study highlights the need to inform the public about appropriate language use and ageism.
Psychometric Evaluation of the Modes of Health Information Acquisition, Sharing, and Use Questionnaire: Prospective Cross-Sectional Observational Study

Published: July 2023

Background
Health information is a critical resource for individuals with health concerns and conditions, such as hypertension. Enhancing health information behaviors may help individuals to better manage chronic illness. The Modes of Health Information Acquisition, Sharing, and Use (MHIASU) is a 23-item questionnaire that measures how individuals with health risks or chronic illness acquire, share, and use health information. Yet this measure has not been psychometrically evaluated in a large national sample.

Objective
The objective of this study was to evaluate the psychometric properties of the self-administered MHIASU in a large, diverse cohort of individuals living with a chronic illness.

Methods
Sharing Information, a prospective, observational study, was launched in August 2018 and used social media campaigns to advertise to Black women. Individuals who were interested in participating clicked on the advertisements and were redirected to a Qualtrics eligibility screener. To meet eligibility criteria individuals had to self-identify as a Black woman, be diagnosed with hypertension by a health care provider, and live in the United States. A total of 320 Black women with hypertension successfully completed the eligibility screener and then completed a web-based version of the MHIASU questionnaire. We conducted a psychometric evaluation of the MHIASU using exploratory factor analysis. The evaluation included item review, construct validity, and reliability.

Results
Construct validity was established using exploratory factor analysis with principal axis factoring. The analysis was constricted to the expected domains. Interitem correlations were examined for possible item extraction. There were no improvements in factor structure with the removal of items with high interitem correlation (n=3), so all items of the MHIASU were retained. As anticipated, the instrument was found to have 3 subscales: acquisition, sharing, and use. Reliability was high for all 3 subscales, as evidenced by Cronbach α scores of .81 (acquisition), .81 (sharing), and .93 (use). Factor 3 (use of health information) explained the maximum variance (74%).

Conclusions
Construct validity and reliability of the web-based, self-administered MHIASU was demonstrated in a large national cohort of Black women with hypertension. Although this sample was highly educated and may have had higher digital literacy compared to other samples not recruited via social media, the population captured (Black women living with hypertension) are often underrepresented in research and are particularly vulnerable to this chronic condition. Future studies can use the MHIASU to examine health information behavior in other diverse populations managing health concerns and conditions.
