Introduction. The management of anemia in chronic kidney disease (CKD-An) presents significant challenges for nephrologists due to variable responsiveness to erythropoietin-stimulating agents (ESA), hemoglobin (Hb) cycling, and multiple clinical factors affecting erythropoiesis. The Anemia Control Model (ACM) is a decision support system designed to personalize anemia treatment, which has shown improvements in achieving Hb targets, reducing ESA doses, and maintaining Hb stability. This study aimed at evaluating the association between ACM-guided anemia management with hospitalizations and survival in a large cohort of hemodialysis patients. Methods. This mul-ti-center, retrospective cohort study evaluated adult hemodialysis patients within the European Fresenius Medical Care NephroCare network from 2014 to 2019. Patients treated according to ACM recommendations were compared to those from centers without ACM. Data on demographics, comorbidities, and dialysis treatment were used to compute a propensity score estimating the like-lihood of receiving ACM-guided care. The primary endpoint was hospitalizations during follow-up; the secondary endpoint was survival. A 1:1 propensity score-matched design was used to minimize confounding bias. Results. A total of 20,209 eligible patients were considered (reference group: 17,101; ACM adherent group: 3,108). Before matching, the mean age was 65.3±14.5 years, with 59.2% men. Propensity score matching resulted in two groups of 1,950 patients each. Matched ACM adherent and non-ACM patients showed negligible differences in baseline characteristics. Hospi-talization rates were lower in the ACM group both before matching (71.3 vs. 82.6 per 100 per-son-years, p<0.001) and after matching (74.3 vs. 86.7 per 100 person-years, p<0.001). During fol-low-up, 385 patients died, showing no significant survival benefit for ACM-guided care (hazard ratio = 0.93; p=0.51). Conclusions: ACM-guided anemia management was associated with a sig-nificant reduction in hospitalization risk among hemodialysis patients. These results further support the utility of ACM as a decision support tool enhancing anemia management in clinical practice.

Published: September 2024

Achieving Urban Flood Resilience (UFR) is essential for modern societies, requiring the implementation of effective practices in different countries to mitigate hydrological events. Green Water Systems (GWS) emerge as a promising alternative to achieve UFR, but they are still poorly explored and present varied definitions. This article aims to define GWS within the framework of sustainable practices and propose a regulation that promotes UFR. Through a systematic review of existing definitions and an analy-sis of international regulations on Sustainable Urban Drainage Systems (SuDS), the study reveals diverse perceptions and applications of GWS and their role in Blue-Green Infrastructure (BGI). The research proposes a standardized definition of GWS and their role in Blue – Green Infrastructure (BGI). The research proposes a standardized definition of GWS and the implementation of SuDS in Peru, addressing the current knowledge gap and contributing to the development of sustainable urban infrastructure.
Gold Recovery from Smelting Copper Sulfide Concentrate
Authors: Moosavi-Khoonsari Elmira , Tripathi Nagendra
Published: September 2024

Gold is a significant revenue source for custom copper smelters facing profitability challenges due to low treatment and refining charges, stricter regulations, and rising costs. Gold is also often blended with copper concentrates, but precise recovery rates from smelting processes are poorly documented despite gold critical economic importance. This paper aims to provide the first comprehensive estimates of gold first-pass recovery across various operational units within the copper sulfide concentrate processing flowsheet. It evaluates the effectiveness of different copper smelting and converting technologies in recovering gold. Optimizing gold first-pass recovery is especially important to enhance immediate financial returns and responsiveness to market dynamics, allowing companies to capitalize on favorable gold prices without delays. Given the absence of direct measurements for gold recovery rates, this research develops an estimation method based on understanding gold loss mechanisms during smelting. The study identifies and analyzes key input and output parameters by examining data from various copper producers. By correlating these parameters with gold loss, the research estimates gold first-pass recovery rates within the copper smelting process. Among integrated smelting-converting routes, the flash smelting to Peirce-Smith converting route achieves the highest gold first-pass recovery (98.8–99.5%), followed by the Mitsubishi continuous smelting and converting process (94.3–99.8%), bottom-blowing smelting to bottom-blowing converting (95.8%), flash smelting to flash converting (95.5%), Teniente smelting to Peirce-Smith converting (95.2%), and the Noranda continuous smelting and converting process (94.8%). The final recovery rates are expected to be higher considering the by-products internal recirculation and post-processing within the copper flowsheet. Additionally, superior gold recoveries are attributed to advanced metallurgical practices and control systems, which vary even among companies with similar technologies. The research demonstrates that copper smelting can effectively recover over 99% of gold from sulfide concentrates. Gold accumulates up to 1000 times its original concentration in anode slime during electrolytic refining, generating 5-10 kilograms of slime per ton of copper, which is further processed to recover gold and other by-products. Major smelters operate precious metal plants where recovering gold from highly concentrated anode slime is both cost-effective and efficient.

Background: The inflammation associated with overweight and obesity seems to alter iron metabolism, but there are few studies evaluating those conditions in children. Thus, we aimed to evaluate leukometric, immunological and hematimetric parameters of overweight and obese schoolchildren. Methods: This is a cross-sectional study, in which 39 children living in Chonim de Cima (Brazil), underwent anthropometric, hematological and immunological assessments. The evaluated parameters were compared between the study group (overweight/obesity, n=15) and the control group (n=24). Unpaired t-test, Mann-Whitney test and linear regression were used for statistical tests and the panoramic profile was used to illustrate differences between groups. Results: The study group had lower mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) and higher TNF levels compared to the control group. Positive correlations were observed between BMI-for-age percentile and total leukocytes (r=0.1493; p=0.0151) or neutrophils (r=0.1395; p=0.0192). Negative correlations between the BMI-for-age percentile and MCV (r=0.1464; p=0.0162) and MCH (r=0.1460; p=0.0164) were found. Furthermore, through the panoramic profile it was noted that the study group had a higher frequency of individuals with high levels of TNF and lower frequencies of individuals with increased hemoglobin and serum iron. Conclusions: Our data suggests that overweight and obesity contribute to a pro-inflammatory context (leukocytes, neutrophils and TNF) and MCV and MCH reduction in schoolchildren.
Leadership and Strategic Management: The Impact of Effective Leadership Skills on Organizational Performance
Authors: Ashley-Osuzoka Joseph K.
Published: September 2024

This paper is intended to correlate the impact of leadership skills on organizations' performance, all organizations grow differently, and their growth depends mostly on positive performance from one year to another which has direct correlations to the leadership dreams, visions, foresight and aspirations for the organization. There is one thing for the leader to have vision, but the leader needs to have followership to assist in implementing their vision to make it goals which translate to performance in the organization and growth. The leadership style or management skills greatly influence how they command and motivate followership to actualize their dreams or the organizational visions and mission which results in the organization's performance. A positive leadership influence produces or actualizes a positive organisational performance that will move the organization towards the vision of the organization. Knowing the difference between a manager and a leader is pertinent in explaining the correlation between leadership and organizational performance. The understanding of these two roles provides credence to the correlation between effective leadership and organisational performance, and the understanding of the term, the use and the importance of strategic management to leadership and organizational performance. There is a wide difference between managers and leaders, which is based on personality and their approach to the resolution of challenges they are confronted with.
Innovative Dynamics: Utilizing Perelman’s Entropy and Ricci Flow for Settler Position Models on Manifolds
Authors: zeraoulia Rafik
Published: September 2024

This paper explores a novel approach to modeling the positional dynamics of stars using discrete dynamical systems. We define star evolution through discrete-time update rules based on right ascension, declination, and distance, incorporating chaotic behavior via nonlinear functions and external perturbations. By applying Ricci flow and Riemannian metrics, we provide new insights into the positional dynamics of stars. Theoretical computations of Perelman entropy are used to assess system complexity, with high-precision Runge-Kutta methods ensuring accurate solutions for our chaotic model. We quantify chaos using Lyapunov exponents and perform bifurcation analysis to study how parameter variations affect the dynamics. Comparing our model to the Lorenz attractor reveals both similarities and unique characteristics in stellar dynamics. Our results show that entropy increases exponentially, indicating that predicting star positions with precision becomes increasingly challenging over time. This study advances the understanding of chaos in celestial systems and contributes to dynamical systems theory by integrating chaos theory with astronomical modeling.

Authors: Díaz Gilberto Javier , Steffenel Luiz Angelo , Barrios Carlos Jaime , Couturier Jean Francois
Published: September 2024

Software quantum simulators are the most accessible tools for designing and testing quantum algorithms. This paper presents a comprehensive approach to building a software-based quantum simulator based on classical computing architectures. We explore fundamental quantum computing concepts, including state vector representations, quantum gates, and memory management techniques. The simulator prototype implements various memory optimization strategies, such as full-state representation, dynamic state pruning, and shared memory parallelization with OpenMP and distributed memory models using MPI. Additionally, data compression techniques, like ZFP, are explored to enhance simulation performance by reducing memory footprint. The results are validated through performance comparisons with leading open-source quantum simulators, such as Intel-QS, QuEST, and qsim. Our findings highlight the trade-offs between computational overhead and memory efficiency. This demonstrates that a hybrid approach using distributed memory and compression offers the best scalability for simulating large quantum systems. This work provides a foundation for developing efficient quantum simulators supporting
more complex quantum algorithms on classical hardware.
Determining the Principal Azimuths of Valles Marineris: A Comparative Analysis of Bezier Spline and GIS Techniques
Authors: James Dan
Published: September 2024

Valles Marineris (VM), the most prominent example of a Martian Valley Network, has been extensively studied for over 50 years, yet no detailed examination of the principal azimuths of the system exists. To address this, two methods are presented to precisely calculate the principal azimuths, a Bezier Spline analysis, and a GIS technique. The medial axis of the main canyon of VM was determined analytically from cubic polynomial splines fitted to 93 coordinate points along both north and south edges of the canyon. These splines were optimized, and medial axis points were calculated through numerical techniques that ensured orthogonality between the tangents of each spline and their connecting normal lines. 1,000 Medial Axis points were extracted, and various regression models constructed, including fitting to sinusoidal and cubic polynomial curves, achieving accuracies with R² values of 0.98 and 0.99, respectively. Principal azimuths were obtained using the sinusoidal equation with the slope of the tangent at any point x simply determined by the derivative of the curve’s equation. This analytic approach was cross-validated by a GIS method (using QGIS software), where a vector medial axis was obtained which produced principal azimuths that agreed with values from the analytic study with a correlation coefficient of 1.00, and a p value of 6.43e-65. The findings suggest that a deterministic process plays a significant role in the structural geometry of VM, highlighting its potential importance in the canyon’s formation.
Spring's Signal: Can Bud Burst Timing Enhance Resistance to Ash Dieback in Europe?
Authors: Przybylski Pawel , Mohytych Vasyl , Sikora Katarzyna
Published: September 2024

Ash dieback (ADB), caused by the invasive fungal pathogen Hymenoscyphus fraxineus, poses a significant ecological and economic challenge across Europe. Fraxinus excelsior (European ash), a key component of forest ecosystems, has experienced mortality rates reaching up to 85% in affected regions, severely threatening its ecological role and economic value. This study examines the relationship between the phenological traits of ash clones, particularly the timing of spring bud burst, and their susceptibility to H. fraxineus infection. The study was conducted in a clonal seed orchard located in northeastern Poland, encompassing 31 ash clones from different bioclimatic regions. Phenological observations of bud burst were carried out from early April to late May during the years 2018-2020, and crown damage and de-foliation levels were assessed multiple times throughout the growing season.
The results confirm that clones with earlier bud burst exhibit significantly higher survival rates and reduced crown damage. It was found that the timing of bud burst is strongly correlated with susceptibility to ash dieback, suggesting that phenological timing is a crucial factor in the selection of genotypes resistant to ash dieback. Statistical analyses, including ANOVA and mixed models, revealed significant differences in susceptibility to infection among clones from different bioclimatic regions. Furthermore, the study high-lights the potential of breeding strategies focused on these traits to enhance the resilience of ash popula-tions. These findings are critical for the development of effective forest management practices aimed at conserving ash resources and maintaining biodiversity in the face of climate change and the ongoing spread of the pathogen.
Ramsey Approach to Vector Fields
Authors: Bormashenko Edward
Published: September 2024

Ramsey approach to the vectors fields is introduced. Set of vectors defined on R^3, taken as the generators of the bi-colored complete graph, is introduced. Vectors are considered as the vertices of the graph. Following coloring procedure is suggested: vertices numbered i and j are linked with the red edge if their scalar product is non-negative; and they are linked with the green edge if their scalar product is negative. This procedure gives rise to the complete, bi-color graph. Graph generated by six vectors inevitably contains the monochromatic triangle: the Ramsey number Ring-like systems of generating vectors are addressed. Applications of the graphs emerging from the vector fields are discussed.

Introduction: Urinary tract infections (UTIs) are a significant global health issue, especially among women, with growing concerns related to antibiotic resistance and adverse effects. The Uromune® vaccine, a sublingual bacterial lysate, represents a promising therapeutic alternative by enhancing immune responses against uropathogens. Methods: This retrospective study, conducted at Hospital Universitari de Sant Joan de Reus from January 2017 to August 2022, evaluated the effectiveness of Uromune® in treating recurrent UTIs (rUTIs). Patients received personalized autovaccines administered as two sublingual puffs daily for three months. Clinical, microbiological, and demographic data were analyzed to assess treatment outcomes and identify recurrence-associated factors. Results: Forty-nine patients (mean age, 61 years, and 59.2% women) were included in the study. Uromune® treatment decreased UTI episodes, from 3.73 ± 0.97 the year before to 0.98 ± 1.36 (P < 0.001) the year after its administration. The number of patients who suffered three or more episodes per year dropped from 43 (87.7%) before the intervention to 7 (14.3%) afterward. The maximum effectiveness of the autovaccine was observed three months post-administration, with 44 patients not experiencing any UTI episodes. Regression analysis identified having had a urostomy, chronic kidney disease, and being immunosuppressed as predictors of recurrence. Conclusion: The Uromune® autovaccine effectively reduced the frequency of rUTIs and associated hospitalizations, offering substantial relief to patients. These findings support the integration of Uromune® into routine clinical practice as a viable alternative to conventional antibiotic treatments.

Published: September 2024

The purpose of this study is to evaluate the amounts of apically extruded 3% sodium hypochlorite using two modes of Er:YAG laser-activated irrigation (LAI), super short pulse (SSP) and shock wave enhanced emission photoacoustic streaming (SWEEPS®), combining three types of laser tips (FT) and conventional syringe needle irrigation (SNI). Methods: Twenty extracted human maxillary central incisors prepared using Reciproc® instruments (size 40, taper 0.06). Irrigant volumetric flow (IVF) was accurately standardized using a precision syringe pump with constant irrigant delivery through the 27G needle. The tested irrigation protocols (60 s) were groups 1: 27-G SNI with 0.05 ml/s constant IVF; group 2: SSP (10 mJ, 15 Hz, pulse duration 50 μs) + Radial SWEEPS FT; group 3: SSP + photon-induced photoacoustic streaming (PIPS) FT; group 4: SSP+SWEEPS FT; group 5: AutoSWEEPS (20 mJ, 15 Hz, pulse duration 25 µs) + Radial SWEEPS FT; group 6: AutoSWEEPS+PIPS FT; group 7: AutoSWEEPS+SWEEPS FT. Each protocol was evaluated in 10 repetitions each. Apically extruded irrigant was collected, and the net weighted. Results: There were significantly lower amounts of extruded irrigant with SNI and SSP using radial SWEEPS and PIPS FTs compared to the other tested laser protocols (p<0.05). In the AutoSWEEPS groups, all three FTs had similar amounts of extruded irrigant (p>0.05). Conclusion: In straight root canals, the use of various fiber FTs in the AutoSWEEPS mode exhibited a higher potential for irrigant extrusion.

Authors: Pont Anna Veronica , Thalib Abdul Rashid
Published: September 2024

This study aims to understand the role of BPJS Kesehatan as a variable that mediates or mediates the relationship between emergency services and patient satisfaction. This can include how administrative processes, access to services, or costs incurred by BPJS affect the relationship between service and satisfaction.
Quantitative studies of a correlational nature are a part of this investigation. In order to forecast endogenous variables (Y) Purchase decisions, researchers conduct correlational studies, which examine the link between one or more variables and other factors. Here, X represents emergency services, Y stands for patient satisfaction, and M for BPJS are the exogenous variables. The purpose of this research is to examine the role of BPJS as a moderator between the impact of emergency services on patients' levels of satisfaction. There were 120 people that filled out the survey, and the margin of error was 10% (based on a 90% truth rate and a 10% error rate). Purposive sampling was used to select participants for the aforementioned studies. Warppls 8.0 and the Warp Partial Least Square program were utilized for data analysis in this investigation.
The study found that PKD significantly and positively affected 71% of participants' happiness with the impact they received. With a 63% influence, PKD has a favorable and statistically significant effect on BPJS. Patient satisfaction is significantly impacted by BPJS, which has a favorable association. When looking at the connection between community satisfaction and emergency services, BPJS is a key mediator. Community satisfaction can be enhanced through the provision of fast and excellent emergency services, and BPJS plays a vital role in mediating this relationship. The beneficial effect of emergency services on community satisfaction can be amplified if BPJS is able to offer sufficient coverage while simultaneously reducing costs and expediting administrative processes

The results could be used as reference points in monitoring deformation in the following years.
The Amalgamation of Traditional and Contemporary Elements in Islamic Education
Authors: 'Aziizah 'Aabidah Ummu , Rofiq Muhamad
Published: September 2024

This study uses Prophet Muhammad's integrated paradigm of Islamic intellectual heritage, which formed the epistemic foundation of the Medinah civilization. If Muslim scientists believed that expertise in one scientific field required proficiency in others or encyclopedic knowledge, polymath scientists have been replaced by highly specialized scientists who ignore these broader scientific regions. Contemporary Islamic scientific references, as a result, lack hybridity. Western knowledge typically trumps Islamic wisdom in scientific credibility. This study, thus, collected and analyzed data using qualitative methodologies and library resources. This study focuses on exploratory qualitative data from the perspectives of various scholars on the "Integration of Knowledge," aiming to reformulate an integration between traditional and contemporary knowledge that is adaptive in Indonesia’s education. Many epistemology studies have concentrated on Islamic literature and ignored Western knowledge. Unlike modern Eurocentrism, certain scientific integration studies value all information sources equally.

Authors: Khoeroni Farid , Syukur Fatah , Nurhadi Agus
Published: September 2024

This study aims to describe the rejection of formal education by the Sedulur Sikep community. This study uses James Scott's theory of resistance to describe the forms and characteristics of resistance to formal education in Sedulur Sikep Kudus. This study employed qualitative research methods with an ethnographic approach to obtain data on community resistance to formal education. The data collection was carried out using interviews, observation, and documentation. The results revealed that the forms of resistance carried out by the Sedulur Sikep Kudus community were closed forms of resistance. It can be interpreted as a conscious rejection of formal education through less systematic procedures. They consistently refuse to engage in formal education due to their commitment to upholding their ancestral traditions and teachings. Also, they harbor doubts about work-oriented formal education. Furthermore, the educational values taught by the Sedulur Sikep community align with Islamic educational values. This study limits its focus on the portrait of the Sedulur Sikep community's rejection of formal education and the relevance of Islamic educational values to the educational values of Sedulur Sikep Kudus. Consequently, further research is needed to complete this study.

Authors: Riwanda Agus , Yusuf Kamal , Syaie Akhmad Najibul Khairi
Published: September 2024

This study aims to analyse the assessment and follow-up processes of Arab learning at Madrasah Aliyah using qualitative methods with a phenomenological approach. It involved 24 Arabic language teachers from Madrasah Aliyah in South Kalimantan. The findings indicated that Minimum Learning Mastery Standards (MLMS) were not adjusted to accommodate student characteristics, subject competencies, and educational unit conditions. Consequently, learning assessments became less credible, often serving merely to fulfil MLMS requirements. Both enrichment and remedial follow-up were perceived as formalities, lacking a basis in the analysis of student assessments, which undermined students' motivation to learn. Teachers encountered ethical dilemmas in assessment and decision-making processes, exacerbated by external pressures for students to meet MLMS benchmarks. The study emphasizes the importance of reducing external pressures in determining MLMS, enhancing teacher competence in adopting new assessment methods, and improving evaluation systems. These improvements are crucial for developing evidence-based structured enrichment and remedial programs

Authors: Camacho Lorenzo Soledad , Pérez Albert Yolanda , Alberich González Joan
Published: September 2024

Reducing urban environmental inequity is one of the main objectives in advancing towards more sustainable cities. This situation implies developing tools that allow for an integrated assessment environmental and social impacts, to reveal inequalities in the distribution of resources and environmental risks. Applying indicators by using Geographic Information Systems (GIS) and statistical tools can be a valid option for fulfilling this aim, since it allows for territorial patterns in disparities to be exposed. The aim of this work is to identify and classify the environmental equity indicators applied to date in studies that use statistical methods and GIS for processing and analysing them. Thus, a scoping review was conducted using the SALSA Framework and PRISMA extension for scoping reviews protocol based on the Scopus, Web of Science and Scielo databases. A total of 31 articles were identified that fulfilled the search criteria and which were developed mainly by countries in North American and Europe. They involved 167 different indicators that demonstrate the complexity and heterogeneity in addressing this topic. Negative aspects of the environment such as pollution, and social factors such as the socioeconomic status, were the most used.
Public Oil and Natural Gas Field Research Helps to Accelerate Technological Adavances

The Department of Energy (DOE), over its nearly 50-year history, has managed its oil and natural gas research and development (R&D) mission through scientific research carried out in government-run or contractor-run test sites, through research grants to small businesses, and through extramural research projects contracted with industry and university partners or other research institutions. At times, DOE has sought to expand its R&D footprint by venturing into the field to do experiments and gather data.

During the past ten years, DOE's National Energy Technology Laboratory (NETL) has undertaken a number of field research initiatives, referred to as "field test sites," that have achieved varying successes. The rationale behind these field test sites is based on the idea that DOE should partner with industry to gain access to historic, current, and emerging producing oil and natural gas fields to accomplish three objectives: (1) publicly test new tools and methods developed by NETL and industry, (2) gather comprehensive data sets and make them accessible for analysis by broad teams of researchers, and (3) attack higher-risk scientific research problems that private industry consortia have not prioritized for funding. In doing so, the primary goal has been to accelerate the development, application and adoption of new technologies and approaches to maximize domestic oil and natural gas recovery and, more recently, reduce environmental impacts.

This approach is not new. For example, in the 1980s and 1990s, DOE (and its precursor organization) funded the Western Gas Sands and Eastern Gas Shales R&D programs (WGSP and EGSP). The WGSP included the drilling and logging of wells at a multi-well field test site in the Piceance Basin, data from which were used to build comprehensive models of tight gas sand geology and production capacity. Similarly, the EGSP program drilled, logged, and tested a number of wells across multiple Eastern basins, helping to design and test well logging and completion techniques suited for tight gas shales and characterizing the gas content and productive capacity of formations that were (at that time) not perceived as economically productive. The public findings of these two scientific inquiries helped to accelerate a revolution in "unconventional" natural gas production that remains the driving force behind the U.S. global leadership in natural gas production today.

In this paper, we point out the advantages of public upstream oil and natural gas field research, highlighting the success of four of the past decade's field test site projects: the Marcellus Shale Energy and Environment Lab (MSEEL) in West Virginia, the Hydraulic Fracturing Test Site 1 (HFTS1) and Hydraulic Fracturing Test Site 2 (HFTS2) in West Texas, and the North Slope Polymer Flood Test Site in Alaska. In addition, we provide detail on 9 other field projects that are currently underway.
CO2 Injection Well Design Considerations: Completion Design to Injectivity Analysis

Published: September 2024

Carbon Capture and Underground Storage (CCUS) has been identified as a viable method for reducing industrially sourced greenhouse gases. In this paper, the methodology and workflow were developed to provide insight on the feasibility of CO2 injection and storage potential in proposed injection well to sustain the target injection rates with proper designed well construction under operating conditions.

Inflow Performance Relationships (IPR) and Vertical Lift Performance curves (VLP) were developed for predicting the temperature and pressure profiles from the wellhead to sandface under well operating conditions (injection pressure and temperature, injection rate). CO2 phase envelope was developed by using proposed CO2 stream composition and plugged-in well modeling. Dynamic multiphase transient analysis software was used for wellbore dynamics to predict pressure and temperature of CO2 at the wellhead, as well as CO2 phase behavior in the wellbore during well transient operations. Proper well construction was applied to ensure that CO2 was safely injected into and contained within the targeted injection zone for the protection of drinking water zones by considering well integrity must be maintained during CO2 injection.

Developed pressure and temperature profiles from well modeling were superimposed on the CO2 phase envelope for designed CO2 injection rates to evaluate CO2 phase changes within the wellbore during CO2 injection. Understanding the steady-state and transient multiphase flow behavior of CO2 within the wellbore is crucial for appropriate well design and operational risk assessment. In transient analysis, well models were developed to represent start-up, shutdown, and re-start of the CO2 injection during life of the well. Casing and tubing stress analysis was performed on the suitability of the proposed casing and tubing under the injection conditions required and with a given set of safety factors using industry recognized software. This analysis enabled to predict how the well construction will respond to various operational conditions, thus ensuring its reliability over the course of the CCUS project.

In this paper, CO2 phase envelope development, well modeling for steady-state and transient analysis in CO2 injection methodologies were combined with proper well construction for designing the wells in CCUS project.
Quantifying Permeability Changes Due to Gas Hydrate Formation in Undersaturated Oil Sandstone Reservoirs: A Numerical Reservoir Simulation Study
Authors: Rathmaier D. , Zerpa L. E.
Published: September 2024

Numerical simulation is used to quantify the resulting permeability effects due to solid phase formation/precipitation during fluid flow in an oil reservoir. The case study consists of a sandstone reservoir saturated with live-oil above the bubble-point pressure that is subject to cold water injection. Due to the relatively low temperature of this over-pressurized shallow reservoir, gas hydrate formation can arise when the reservoir temperature falls below 7 °C, reducing permeability as observed in previous coreflooding tests. Digital representations of the core samples used in the experiments were created with a commercial reservoir simulator to follow the experimental procedures. These include tracing a cooling temperature ramp starting outside of the hydrate stability curve towards inside the hydrate forming region and differential pressure changes due to hydrates plugging the pore space, also implying a permeability alteration. The numerical simulations are compared with the experimental results and explore the hurdles and limitations of modeling this reactive fluid flow with a commercial reservoir simulator on the continuum scale. Reservoir simulation is suitable to model the thermodynamic hydrate formation conditions that result in a realistic spatial hydrate distribution but is not able to capture the microscopic amount of solids precipitation that provide a quantitative analysis of permeability reduction on the centimeter scale. The upscaling of the laboratory coreflooding scale simulations to the field-scale for counter-acting this microscopic behavior resulted in a localized permeability reduction of up to around 40%.
