Published: December 2024

Abstract
This paper aims to comprehensively introduce the historical, present, and future landscape of standalone screens’ design, and evaluation. The evolution of sand control screen design, testing, and implementation is explored, with a focus on its role in overcoming the challenges posed by heterogeneous geological formations and complex EOR strategies. Field case data will be used to illuminate the need for a more scientific approach to sand control engineering.
As operators venture into increasingly complex and heterogeneous formations, precise sand control engineering becomes imperative. This paper will delve into the historical standalone screen design, highlighting its advantages and drawbacks. Through field case examples, we will underscore the necessity for a more scientific approach. A comprehensive sand control design cycle—from information acquisition and lab testing to data analytics, manufacturing, field installation, monitoring, and post-performance analysis—will be elucidated.
Since 2017, the first attempt to optimize the standalone screen design has led to the development of a sand control best practice. The best practice outlines the guidelines and steps that must be followed on the sand control design, evaluation, and monitoring for future pads. The guidelines have been successfully implemented in the field with remarkable success and no failure to report to date. The guidelines specify the sampling method, the testing requirement to identify the sand variation within the studied sandbox, and selection criteria and evaluation testing through sand retention testing. The guidelines specify the manufacturing tolerances for each screen type. Additionally, the monitoring details for wells completed with sand control and adjustment of the best practices based on the monitoring data are outlined in the guidelines. This paper shares the rich history and lessons learned from sand control design from two fields where different standalone screens are used as the primary completion method.
Designing and optimizing the sand control screens for wells is a formidable challenge, given the intricate nature of downhole environments. This paper conveys lessons and learns from field case studies to the industry, shedding light on the complexities and offering guidance for future sand screen engineering. The insights shared aim to contribute to the continuous improvement and advancement of sand control practices in the global hydrocarbon recovery sector.
Lower Carbon Footprint Production in SAGD Late Life Recovery

Published: December 2024

Abstract
The world needs reliable energy. As an industry, we supply that energy. Moreover, our product is one of the major contributors to increasing atmospheric CO2. Steam assisted Gravity Drainage (SAGD) technique alone contributes nearly 1.4 million barrels per day of oil production but with a range of steam oil ratios, the effectiveness of this production method is often challenged and seen as having high associated GHG emissions per barrel.
We cannot solve this dilemma, but by better understanding the sciences of the reservoir and implementing new technologies at the primary level of production, we can help to be part of the solution. One production enhancement technique, injecting NCG at the late life SAGD wind down process is an effective but challenging operation due to high mobility of the gas and subsequent breakthrough at the production well. A new design of Autonomous inflow control valve's (AICV) can distinguish the difference in viscosity of the fluid, and therefore they can strongly choke and shut the NCG effluents zones as breakthrough occurs in the SAGD production well.
The AICV design is truly autonomous based on Hagen-Poiseuille equation and Bernoulli's principle. The AICV is utilizing the difference in flow behavior in a laminar flow restrictor and a turbulent flow restrictor to differentiate fluids based on the difference in pressure drop between oil, water, emulsions, gas, CO2 and steam. This will allow the AICV to choke and/or shut off unwanted water, gas, CO2 and steam coming into the producer well. To understand the AICV behavior for a NCG breakthrough application, a laboratory experiment which illustrate the performance of AICV technology and reference orifice type ICD technology have been conducted.
Laboratory experiment results illustrate the performance difference between AICV technology and reference orifice type ICD technology illustrate a significant, of more than 80% reduction, in NCG choking performance, when compared to the ICD type nozzle. The laboratory test performance results are used in reservoir simulations. Reservoir simulation results show that utilizing AICV in late life SAGD production well can significantly reduce NCG production and improve the recovery of SAGD operation by retaining more of the injected gas within the reservoir.
In today's engineer's toolbox, a variety of new technologies exist that can help achieve the targets for late life SAGD. The new editions to Flow Control Device (FCD), Autonomous Inflow Control Valve (AICV), has evolved to the point that operators can operate in late life in a way that could demonstrate clear economic efficiencies with a reduced environmental impact. Reducing NCG breakthrough, greatly improves the economics and reduce greenhouse gas emissions for each barrel of oil produced thus reducing the carbon footprint and the impact to late life SAGD operation.
Improving ESP reliability in Direct-To-SAGD completions: A Case Study
Authors: Joseph Rejish , Belyaev Sergey , Eto Kome 
Published: December 2024

Summary
One of the methods to establish continuous emulsion production between producer and injector wells in a steam-assisted gravity drainage (SAGD) scheme, is steaming the well-pair simultaneously. As for the producer wellbore, a typical completion implies a two-stage workover with installation of the Electric Submersible Pump (ESP) and instrumentation right after the completion of the steaming phase. A novel method of a single stage workover - going direct to SAGD with steaming past the ESP's was trialed at Suncor Energy's Firebag field in Northern Alberta. The first full direct-to-SAGD (D-SAGD) Firebag pad faced multiple challenges during steaming phase and production startup. One of them was long-term exposure of the ESP systems to the high temperature steam along with challenging temperature cycling during the fall-off tests that contributed to early failures in the power delivery system. Continued D-SAGD implementation needed a system that is capable of withstanding high-temperature steam exposure for several months along with multiple temperature cycles. After thorough engineering analysis of failure modes, a plan was established to deliver a new, redesigned system. Multiple new concepts have been developed for mechanisms and materials with the criteria to meet the reliability requirements and were successfully qualified after being subjected to extensive testing. As a result, an ESP system specific to D-SAGD style of completion was developed, deployed, and successfully started. New design has contributed to positive economic and environmental effects at both Firebag and MacKay River projects.

Published: December 2024

Abstract

Overexploitation of groundwater resources has become more visible and has caused groundwater depletion in many countries. Assessment of groundwater potential is a vital step in enhancing the sustainable management of groundwater resources. This study aimed to identify and locate the groundwater potential zones of the Fentale district by integrating remote sensing and geographic information systems via an analytical hierarchy process. Groundwater potential zones were created using eleven influencing factors, including geology, topographic position index, drainage density, lineament density, rainfall, soil type, soil texture, elevation, slope, topographic wetness index, and land use/land cover. Thematic layers of these influencing factors were then generated in raster format, and given appropriate weightage based on their relative reaction to groundwater occurrence. The groundwater potential zone in the study area was generated and classified into four groups: very low, low, moderate, and high. The very low, low, moderate, and high potential zones were represented by 0.2% (244.73 hectares), 28.754% (34,322.65 hectares), 56.03% (64,309.52 hectares), and 17.164% (20,489.15 hectares), respectively. The final potential zone map aligns well with the weighting and ranking analysis conducted. Based on these findings, almost all inactive wells were found in the low and very low potential zones. Finally, the result obtained was validated using 35 wells yield data, and the receiver operating characteristic curve method from which the accuracy obtained was above 80%, and the area under the curve was found to be 0.813. Given the validated findings, it’s evident that there is a significant possibility for groundwater potential in the district. Concerned bodies should take this opportunity to tackle the water scarcity the aridity of the district and focus on sustainable management of this vital resource.

Abstract

There is significant interest in understanding the mechanism behind the photochromic properties and light-induced structural and chemical alterations in yttrium oxyhydride, which remains unclear. This lack of knowledge hinders our ability to comprehend the causes of degradation, enhance photochromic performance, control color, improve durability, and fully utilize the material's potential applications. In this work, first-principles calculations have revealed that anion vacancies can cause the photochromic effect in yttrium oxyhydride. Such vacancies form deep localized energy levels in the band gap. Absorption of sunlight transfers electrons from the valence band to these defect levels and changes the charge state of the vacancies leading to the photochromic effect and lattice relaxation. This relaxation involves yttrium cations shifting outwards for positively charged vacancies and inward for negatively charged vacancies. These shifts cause lattice relaxation and affect the local environment around yttrium cations by inducing changes in the second coordination shell. Using extended X-ray absorption fine structure spectroscopy (EXAFS) on transparent and photodarkened yttrium oxyhydride films, we concluded that UV light illumination induces lattice relaxation in the second coordination shells of yttrium cations in agreement with the results of first-principles calculations.
FONDUE - Fine-tuned Optimization: Nurturing Data Usability &amp; Efficiency

Published: December 2024

Abstract

To provide good results and decisions in data-driven systems, data quality must be ensured as a primary consideration. An important aspect of this is data cleaning. Although many different algorithms and tools already exist for data cleaning, an end-to-end data quality solution is still needed. In this paper, we present FONDUE, our vision of a well-founded end-to-end data quality optimizer. In contrast to many studies that consider data cleaning in the context of machine learning, our approach focuses on various scenarios, such as when preprocessing and downstream analysis are separated. As an adaptive and easily extendable framework, FONDUE operates similarly to proven methods of database query optimization. Analogously, it consists of the following parts: Rule-based optimization, where the appropriate data cleaning algorithms are selected based on use case constraints, optimizer hints in the form of best practices, and cost-based optimization, where the costs are measured in terms of data quality. Accordingly, the result is an optimized data cleaning pipeline. The choice of different optimization goals enables further flexibility, e.g. for environments with limited resources. As a first building block of FONDUE, we present CheDDaR, which is used to detect errors and measure data quality. Both are important tasks for improving data quality with FONDUE.
Aerodynamic Significance of Mass Distribution on Samara Descent

Published: December 2024

Abstract

Samaras, a distinct category of fruit, are composed of heavier seeds and lighter wings. Diversity in morphologies and structures subtly contributes to the flight patterns of various seeds, thereby serving as a key factor in the reproductive strategies of plants. To explore the mechanisms underlying various samara flight behaviors, we proposed an effective scheme by manipulating the mass distribution on a plate to mimic various three-dimensional descent behaviors of samaras. Through this framework, we experimentally identified and characterized four distinct flight modes. The three-dimensional vortical structures were then numerically analyzed to gain insights into the samara-inspired flight behaviors. Our study demonstrates how strategic mass distribution in samaras leads to diverse flight behaviors that leverage vortices to enhance seed dispersal, offering a fresh perspective for the design of biomimetic fliers.

Published: December 2024

Abstract

Intravoxel incoherent motion (IVIM) MRI is a non-contrast technique that estimates diffusion and perfusion parameters using multiple b-values. This systematic review and meta-analysis aimed to compare the diagnostic accuracy of IVIM with contrast-enhanced (CE) perfusion MRI in oncology imaging. Following PRISMA guidelines, a comprehensive literature search across five databases identified studies that compared IVIM and CE MRI in patients with brain, breast, and rectal cancers. Meta-analyses were performed using R software. A total of 18 studies met the inclusion criteria, encompassing 123 gliomas, 231 breast, and 208 rectal cancer lesions. IVIM demonstrated comparable diagnostic performance to dynamic susceptibility contrast (DSC) MRI in gliomas, with a pooled AUC of 0.84, sensitivity of 92.27%, and specificity of 74.06%. In breast cancer, IVIM outperformed dynamic contrast-enhanced (DCE) MRI, with AUCs of 0.856 compared to 0.786. For rectal cancer, IVIM and DCE both showed moderate diagnostic accuracy, with AUCs of 0.62 and 0.64, respectively. Correlation analysis showed moderate relationships between IVIM and DSC/DCE parameters, particularly in gliomas and rectal cancer. IVIM MRI presents a promising non-contrast alternative to CE techniques, especially in gliomas and breast cancer, where it matched or exceeded CE perfusion performance. Further studies are needed to validate IVIM’s efficacy across more cancer types and to strengthen its correlation with CE parameters.

Authors: Yuill Nicola , Elphick Camilla , Marshall Jess , Jones Wendy D , Waite Jane , Viner Hannah 
Published: December 2024

Abstract

Background
Wiedemann-Steiner Syndrome (WSS) is a rare, variable neurodevelopmental condition associated with developmental delay, intellectual disability and congenital abnormalities. There are few investigations into behavioral characteristics. Importantly, parental perspectives are particularly lacking. This study investigated commonalities in the behavioral characteristics through the perspectives of parents’ lived experiences.
Method
We conducted in-depth interviews with 25 parents of children with WSS in the United States and United Kingdom, tapping lived experience and specific examples of behavior, relationships and communication. Responses were analysed using reflexive thematic analysis.
Results
We report three main themes: intense sociability (confirming questionnaire-based research), intense relationships and executive dysregulation (novel findings). We also found previously unreported sensory sensitivities and cognitive patterns of uneven memory and poor comprehension.
Conclusions
These data direct from parent experience reveal novel commonalities in behavior and relationships in this group. Findings should inform clinical assessment and diagnosis, new research questions and choice of patient-focused outcome measures for clinical interventions. The findings also contribute to improved practice in providing care and support for people with WSS and their families and to guidelines for more tailored education and improved healthcare.
3D reconstruction of shallow sea environment using direct system calibration and faint laser line extraction
Authors: Garai Arpan , Kumar Subodh 
Published: December 2024

Abstract

Virtually recreating an underwater scene requires 3D data of its objects. Creating a dense 3D point cloud of shallow underwater objects using a laser in the presence of significant ambient light is challenging. Although several methodologies have been proposed for the same, they essentially work in low-light environments. In particular, current techniques are unable to quickly and effortlessly generate dense point clouds of underwater objects under varying light. This work fills that gap. It is based on triangulating a rotating low-power line-laser. It generates the point cloud online and automatically. It works in sunlight, which tends to washout low-power laser in shallow waters. To reduce the cumulative errors during calibration, our data-centric method calibrates the entire system directly, unlike the existing methods, where multiple parameters are calibrated separately. We also propose an analytical technique to segment faint-laser lines in an underwaterlit environment, which does not depend on the availability of large training data. An evaluation of the performance of the proposed method in different lightingconditions is reported.

Published: December 2024

Abstract

Salinity negatively affects plant growth and development, particularly during the seed germination and seedling establishment stages, which are the most vulnerable due to combined osmotic stress and ionic toxicity. This study investigates the effects of salinity, simulated using NaCl, on the germination and early growth of ten quinoa genotypes (Colorado 407D, Rosa Junin, Sayana, Baer, Faro, Titicaca, Negra Collana, 11WAQ, Puno, and Vikinga). The experiment was conducted under controlled conditions with varying salinity levels (50, 100, 200, 300, and 400 mM NaCl). Results revealed that increasing salinity levels significantly reduced germination percentage, seedling shoot length, root length, fresh weight, and dry biomass, while increasing mean germination time, time to 50% germination, chlorophyll A, B, and carotenoid content, and superoxide dismutase, catalase, and peroxidase activities. Genotypes varied in their response to salinity stress, with some showing higher salinity tolerance than others. Genotypes like Colorado 407D, Sayana, Titicaca, Faro, Rosa Junin, and 11WAQ exhibited greater resilience, suggesting their potential for cultivation in salt-affected regions. This study highlights the importance of identifying and cultivating salt-tolerant quinoa genotypes to enhance food security in saline environments.
Coagulation and thyroiditis are factors associated with adverse pathological features in differentiated thyroid cancer:A retrospective cohort study
Authors: Chen Xiao , Wang Han-yu , Yu Lu , Liu Jia-qi , Sun Hui 
Published: December 2024

Abstract

Objective
Lymph node metastasis (LNM) and capsular invasion (CI) are the main pathological features leading to poor prognosis of differentiated thyroid cancer (DTC), and there is a lack of effective diagnostic methods before surgery. Therefore, this study was designed to analyze a large number of preoperative clinical features of DTC and identify factors closely related to those two pathological features.
Methods
4557 patients with DTC, postoperative pathological results showed LNM in 2146 cases and CI in 2783 cases were retrospectively included. The preoperative blood, urine, serum laboratory test and ultrasound of thyroid were performed for data collection. A total of 74 clinical features were analyzed by the methods of principal component analysis (PCA), and key principal components were extracted for regression analysis of LNM and CI as well as subgroup analysis.
Results
11 key clinical features were used for principal component analysis, and 6 principal components PC0-PC5 were finally obtained. PC0 is mainly composed of prothrombin time and international normalized ratio, and the score represents better coagulation function and has a protective effect on LNM. PC1 is mainly composed of thyroid peroxidase antibody and thyroid texture, and the score represents the severity of thyroiditis and has a protective effect on LNM and CI.
Conclusion
Thyroiditis and coagulation function were identified by principal component analysis as protective and risk factors for adverse pathology of DTC, meaning they were closely related to tumor metastasis and invasion.

Published: December 2024

Abstract

This study was designed to analyse the clinical manifestations, cerebrospinal fluid (CSF), imaging features, and treatment of patients who were CSF was positive for NMDAR antibodies (NMDAR-ab) and seropositive for MOG antibodies (MOG-ab). The clinical manifestations of thirteen patients with overlapping antibodies and presenting signs and symptoms of general encephalitis, such as fever and headache, impaired consciousness, mental and behavioural disturbances, and seizures, at the initial onset of disease were reviewed. Cranial MRI suggested that the most frequently involved areas were cortical and subcortical, and meningeal enhancement was observed in a few patients. Intravenous methylprednisolone (IVMP) and intravenous immunoglobulin (IVIG) are the mainstays of treatment in the acute phase. The median mRS score was 2 (1, 2.5) before treatment and 1 (0.5, 1) after treatment. Compared with the MOGAD group, the overlapping antibodies group had a greater proportion of adult patients who were admitted to the intensive care unit (ICU), experienced common mental and behavioural disturbances, had cortex or subcortical involvement on cranial MRI, and had less enhancement on gadolinium-enhanced scans (P < 0.05). Compared with the anti-NMDAR encephalitis group, the overlapping antibodies group had lower incidences of mental and behavioural abnormalities and seizures, and the brachium pontis was more prone to abnormal signals on cranial MRI (P < 0.05). Kaplan-Meier survival analysis revealed that during the 6–48 month follow-up period, there was no statistically significant difference in the recurrence rate between the overlapping antibodies group and the MOGAD group or the anti-NMDAR encephalitis group (P > 0.05).
