Abstract
This paper presents the results of an integrated study with a techno-economic solution for the treatment and re-injection of produced water (PW) in an onshore oilfield carbonate reservoir. The reservoir currently utilizes aquifer water injection for pressure maintenance, coupled with PW disposal. As PW volumes have increased over the years and disposal capacity has declined, the need for an alternative solution has become imperative. The proposed solution involves using PW for pressure maintenance, but the tightness of the reservoirs presents challenges such as potential formation damage and injectivity reduction. As a temporary solution the PW is mixed with aquifer water for reservoir pressure maintenance, aquifer water can be diluted with approximately 35% PW to enable reinjection without any treatment ([1] Grutters et al., 2023). The long-term objective presented in this paper is to define PW specifications and identify required PW treatment technologies and facilities upgrade to make it suitable for re-injection ([2] Lu Xianhui, 2023).
Produced Water Re-injection (PWRI) specifications were defined from core flood experiments together with corrosion experiments, representing four reservoirs with permeability of 1-10, 10-100, 100-500, 500-1000 mD. Mature PW treatment technologies, both mechanical and chemical, were investigated and compared whilst considering existing facilities upgrades to enable cost-effective PWRI to meet future production targets ([3] Mohammad A. Al-Ghouti et al., 2019).
Critical PWRI specifications OIW and TSS ranged from 51.5 to 246 mg/L and 24 to 64 mg/L respectively, for permeability of 1-10, 10-100, 100-500, 500-1000 mD. Corrosion experiments showed that the PW satisfied both the average corrosion and pitting corrosion requirements. Induced Gas Flotation (IGF) downstream of the existing PW skimming tank was proposed to reduce OIW &lt; 40mg/L and TSS &lt; 20mg/L with chemicals dosing meeting the PWRI requirements. The CAPEX and OPEX for the existing PW facilities upgradation and new built facilities were also estimated.
In order to reduce cost, the project was proposed to construct in three phases based on PW profile, with phase-1 to upgrade existing facilities. This integrated study has resulted in techno-economically feasible solutions that contribute to enhance reservoir water injection & support oil production and achieve sustainable targets by eliminating PW disposal in water aquifers.

Abstract
The objective of this paper is to introduce an innovative technique for managing water injection systems. The methodologies used in this paper involve swing headers that efficiently transition between seawater and water associated as a byproduct from oil wells, in response to increase in the water cut of produced oil. This technique optimizes water usage, eliminates waste, and reduces environmental pollution. The paper describes in the utilization of swing headers in water injection systems. This strategy involves the utilization of swing headers, enabling a transition between seawater and byproduct water from oil wells, as required. Furthermore, the rate of seawater and byproduct water are interactively set to be within the pumps operating windows to optimize their efficiencies. The procedure incorporates advanced filtration technology twinned with meticulous water monitoring, ensuring a smooth transition between seawater and produced water. This smooth transition would minimize the impact on reservoir injection quality while facilitating required water to be disposed from produced water. The implementation of this method provides an efficient way to manage any sudden increase or decrease in produced water from oil wells, minimizing waste and reducing environmental contamination. During high water cut, the injection wells will be swung to inject disposal water, while in low water cut the injection wells will be swung to seawater injection. This dynamic in water injection would ensure field readiness for sudden changes in produced water that's associated with rapid oil target changes. Detailed monitoring of water quality and the application of filtration technology have ensured optimal management in the water injection process. This system has proven to be flexible and cost-effective, while being environmentally friendly by eliminating water waste and reducing CO2 emissions by running seawater pumps on low rate with high efficiency. Ultimately, this paper concludes that this adaptable approach offers a comprehensive solution for prevalent water management challenges in the oil field industry. The introduction of swing headers to water injection systems, a pioneering approach, promises to challenge and enhance conventional strategies in the industry. Moreover, it offers an ingenious solution to water compatibility challenges related to the switch between seawater and byproduct water. The solution presented addresses water compatibility issues by facilitating an efficient transition between using seawater and byproduct water through an innovative swing header system. This breakthrough allows for the optimization of lowering waste output and cutting down on ecological pollution in the process. By addressing key concerns such as dynamic water cut, maximizing facility water pumps efficiency, and sustainable recycling sure to be of paramount interest to stakeholders.

Published: March 2024

Abstract
The objective of this paper is to scrutinize the technical feasibility and performance of Nanofiltration technologies in sustainable water injection for Abu Dhabi National Oil Company (ADNOC)'s onshore oil reservoirs. It evaluates the efficiency and environmental impact of Nanofiltration, initially focusing on reservoirs with a production capacity of 1.8 million barrels per day, and later extending to 2.4 million barrels per day. A hybrid approach combining computational simulations and empirical data collection is used. Laboratory experiments evaluate Nanofiltration efficacy in filtering seawater to meet required quality standards for oil reservoir injection. Field data from ADNOC's existing operations serve as a baseline for comparative analysis. Findings indicate that Nanofiltration technologies demonstrate a high degree of efficacy in filtering seawater to the required quality standards for oil reservoir injection. The technology shows promise in reducing the environmental footprint by minimizing groundwater extraction. Economic evaluations, although not the primary focus, suggest that Nanofiltration could become cost-effective in the long run. Initial phases targeting reservoirs with 1.8 million barrels per day production have been promising, validating the technology's scalability. This paper introduces a rigorous technical analysis of Nanofiltration technologies deployed for water injection in oil reservoirs, using ADNOC's operations as a case study. For engineers and technical experts, the paper provides a deep dive into the technological aspects of Nanofiltration, backed by empirical data and computational models, offering a technical roadmap for adoption in similar settings.

Abstract
Early in the well's life, the presence of formation water under strong water drive supports oil production. Eventually with time, this will become a problem that is challenging to manage. Maintaining and growing North Kuwait's oil production year after year made it impossible to continue producing well with high water production caused by conning effect. The critical coning rate required for lower Burgan (LB) to eliminate the conning effect and continue producing with low water cut (WC), as determined by Chappelear and Hirasaki correlation, is ± 300 BLPD. In order to prevent coning, an LB well should be produced at a rate lower than 300 BOPD. Producing wells at a rate lower than 300 BLPD is not feasible due to the high requirement of oil rate that north Kuwait targets.
Coning Control Completion (CCC) is a cutting-edge technology used in North Kuwait to solve Lower Burgan formation (LB) coning problems. A reversible Electric Submersible Pump (ESP) is part of this completion system that is positioned below the oil-water contact (OWC). In order to control the progression of the water cone inside the oil zone, the reverse ESP generates a counteractive pressure drop below the OWC.
Redirecting water into the underlying reservoir by drawing it below the desired zone's OWC is a crucial function of the reverse ESP. The quantity of generated water that rises to the surface is reduced by this process keeping the same liquid rate. Water cut (WC) has been decreased as a consequence of the effective use of CCC in North Kuwait, going from 90% to around 40 %.
The successful implementation of CCC in North Kuwait has helped and enhanced the development plan for lower Burgan and will help controlling conning issue world wide

Published: March 2024

Abstract
Managing oil and gas production requires the integration and analysis of multiple sources, including chemical analysis data, laboratory reports, and specialized analyses. Quick and efficient access to this data will allow engineers to focus on generating analysis and decision-making tasks to improve production and field performance.
This document presents an overview of the project on the implementation of an automated workflow designed to support the analysis physicochemical of production water applied to Colombian fields. The project was developed through cloud apps, as a new platform that supports the visualizer solution, using data analysis and the production domain of physicochemical.
The implementation consists of three stages, the first standardized the information from the field physicochemical, which was stored in Database as a centralized platform. With the results from the first step, the second stage begins to apply different automated calculations to establish the Langelier, Ryznar, Puckorius and Larson Indexes, among others, to determine the stability of the fluids and formations of corrosion, wax, scale, asphaltenes with the objective of identifying and improving self-sufficiency, product consumption and ensuring operational autonomy.
The third stage and completion of the solution workflow is integrated through data analysis where the calculations are visualized based on different knowledge, avoiding delays associated with chemical problems and allowing the flow assurance of the wells that are part of the field. This workflow resulted in considerable time savings as relevant data will be automatically updated and used in analysis, instead of manual processing, improving efficiency in field management practices. Furthermore, it is a new workflow that can be replicated in other solutions.

Published: March 2024

Abstract
Introduction We will employ a mixed-methods approach to evaluate the real-life experiences and requirements of caregivers for children diagnosed with rheumatic diseases, with the aim of providing insights for both research and clinical interventions. Understanding the genuine experiences and requirements of caregivers and implementing targeted interventions can have a positive impact on the physical and mental well-being of caregivers, ultimately reducing their burden and enhancing their quality of life. While there has been a gradual increase in research in this area in recent years, there remains a gap in the evidence that comprehensively and systematically reflects the actual experiences and needs of caregivers.
Methods and analysis We will conduct a comprehensive search across multiple databases, including MEDLINE (PubMed), Embase (Ovid), PsycINFO (Ovid), CINAHL (EBSCO), Cochrane Central Register of Controlled Trials (CENTRAL), CNKI, WanFang, and VIP, as well as the grey literature, to identify primary studies published in either English or Chinese since 2000. In our systematic review, we will employ a mixed methods assessment tool to evaluate study quality, and we will apply a convergent integration approach to synthesize the data. Studies employing qualitative, quantitative, or mixed methods to elucidate the authentic experiences, emotions, and requirements of caregivers of children diagnosed with rheumatic diseases will be included in this review.
Ethics and dissemination Ethical approval is not needed, as no primary data will be collected. The results will be made available through a peer-reviewed publication.

The feasibility and acceptability of delivering and evaluating a physical activity intervention (ACCEPTANCE) for cervical cancer survivors
Authors: Millet Nessa , McDermott Hilary J , Munir Fehmidah , Edwardson Charlotte L , Plekhanova Tatiana , Moss Esther L 
Published: March 2024

Abstract
Background: Cervical cancer treatment can be associated with long-term physical, psychological and emotional issues leading to compromised quality of life (QOL). Physical activity (PA) may improve QOL in cervical cancer survivors.
Methods: A one arm pre/post- feasibility study with parallel process evaluation was conducted to test the feasibility and acceptability of a 12-week PA intervention (ACCEPTANCE). Feasibility was determined by using pre-established criteria relating to: inclusion criteria, recruitment and retention, compliance with intervention components and compliance with evaluation measures. The 12- week intervention consisted of: 1) an online education session on the benefits of PA and a barrier identification and problem-solving session; 2) a Fitbit monitor; 3) daily and weekly diary entries; 4) brief fortnightly online health coaching sessions; and 5) organising and participating in group walks 6) online social interaction via a messaging group. Measures included accelerometer assessed PA and sleep, quality-of-life and PA behaviour change questionnaires distributed at 4-time points (baseline, week-6, week-12 and week-24). Process evaluation measures were questionnaires on the acceptance of intervention components and semi-structured interviews with participants after completion.
Results: 30 participants were recruited with a retention rate of 77% at week-24. The education session, health coaching and Fitbit PA monitor were deemed to be feasible based on compliance rates whilst the online messaging group, diary and group waking compliance suggested that modifications would be needed. Accelerometer and questionnaires were deemed to be feasible evaluation measures based on compliance rates. Process evaluation results suggest that the Fitbit and health coaching sessions were perceived to be the most beneficial aspects of the programme as they enabled self-monitoring of behaviour and goal setting. Unexpected mechanisms of behaviour change were the integration of a small change approach and formation of habits to facilitate PA, whilst barriers to behaviour change included the online, virtual nature of the programme, poor mental health, and environmental challenges. Physical activity levels were higher after the intervention, whilst QOL was seen to worsen throughout the study.
Conclusions: The ACCEPTANCE study is deemed to be feasible based on criteria established a priori, and only minor modifications would be needed ready for a definitive randomised control trial. The intervention showed potential to increase PA, through hypothesised mechanisms of self-monitoring behaviour and problem solving and unexpected mechanisms such as habit formation.

Authors: Boeffard Camille , LOIN Justine , CLOUET Roselyne , GAUDIN Alexis , CORRE Pierre , PRUD'HOMME Tony 
Published: March 2024

Abstract

Background: Cleft lip and/or palate is the most common congenital orofacial deformity, affecting 1/800 births. A thorough review of the literature has shown that children with cleft have poorer oral hygiene and dental health than other children, with higher levels of caries in both temporary and permanent teeth and poorer periodontal health. Cleft patients are treated by a multidisciplinary team that aims to provide comprehensive care from pre- or post-natal diagnosis to early adulthood and the end of growth. We aim to assess, through a single-center, prospective, randomized and controlled clinical trial conducted at the Nantes Cleft Centre, the impact of an enhanced dental program on oral hygiene and dental health in cleft patients.
Methods: Patients aged 3 to 15 years with unilateral or bilateral cleft lip and/or palate will be offered to participate in this study. After acceptance, patients will be randomly assigned to 2 groups: test group or control group. For the control group, there will be no change in the patient's care, and they will continue to see their surgeon on an annual basis.
For the test group, a 30–45-minute consultation will be added to the annual check-up. During this visit, patients and their parents will receive oral and written oral hygiene instructions to improve oral hygiene knowledge and brushing technique. If necessary, dental treatment will be provided at the same appointment or at a later date. In addition, patients will be contacted via telemedicine every 2 months to increase motivation, and an additional dental appointment will be scheduled at 6 months.
Discussion: This is a single-center study which, if conclusive, could lead to a paradigm shift in the dental care pathway for cleft patients.

Published: March 2024

Abstract
Inverse design with topology optimization considers a promising methodology for discovering new optimized photonic structure that enables to break the limitations of the forward or the traditional design especially for the meta-structure. This work presents a high efficiency mid infra-red imaging photonics element along mid infra-red wavelengths band starts from 2 µm to 5 µm based on silicon nitride optimized material structures. The first two designs are broadband focusing and reflective meta-lens under very high numerical aperture condition (NA = 0.9). The two designs are modeled by inverse design with topology optimization problem with Kreisselmeier-Steinhauser (k-s) aggregation objective function, while the final design is depended on novel inverse design optimization problem with double aggregation objective function that can target multi focal points along the wavelength band producing high efficiency achromatic broadband multi-focal meta-lens under very high numerical aperture (NA = 0.9).

Abstract

Recent developments in artificial intelligence (AI) have provided new technologies that can aid in detecting cognitive decline. This study developed a voice AI model that screens for cognitive decline solely based on a short conversational voice sample. This study involved collecting voice data, AI machine learning (ML), and confirming accuracy using test data. AI extracts multiple voice features from the collected voice data to detect potential signs of cognitive impairment. Data labeling for ML was based on Mini-Mental State Examination scores; scores of 23 or lower were labeled as “cognitively declined (CD),” while scores above 24 were labeled as “cognitively normal (CN).” A fully coupled neural network architecture was employed for deep learning using voice data from 263 patients. Twenty voice samples, comprising “one-minute conversations,” were used for accuracy evaluation. The developed AI model achieved an accuracy of 0.950 in discriminating between CD and CN individuals, with a sensitivity of 0.875, specificity of 1.000, and average area under the curve of 0.990. This voice AI model serves as a promising cognitive screening tool accessible via mobile devices, requiring no specialized environments or equipment.
Plastic sex-trait modulation by differential gene expression according to social environment in male red deer

Abstract

Mates competition encourages individuals to modulate characters involved in mating success. Adult Iberian red deer (Cervus elaphus hispanicus) males show a dark ventral patch (DVP) that plays a central role in mating rivalry, whose size and chemical compounds varied according to the level of male-male competition within the population. In the pigmentation of the DVP appears, after urinary excretion, a molecule called DOPEG originating from the metabolism of norepinephrine, leading us to investigate whether differential expression mechanisms of key genes (DBH and TH) encoding enzymes catalyzing the process can be sensitive to different competitive population situations and responsible for the plastic development of the DVP in red deer. We found that social environment with higher intrasexual competition, where male invest more in sexual traits, was associated with increased levels of DBH and TH transcripts, while Dopamine showed reversed values. We found alternative splicing for the TH gene, although differences between social environments appeared just related to expression levels. Our results support the internal cause of trait modulation based on differential gene expression in relation to the conditions of intrasexual competition in social environment. We propose the quantification of DBH transcripts as a molecular biomarker of male red deer reproductive activity.
