Authors: Subburam Rajalakshmi , Sharma Nidhi , Amthul Nimrah 
Published: November 2024

Preeclampsia and eclampsia remain significant challenges in both maternal and perinatal health worldwide, with a pronounced impact in regions such as India, where access to comprehensive maternal care can be limited. The objective of this study was to examine the outcomes for both mothers and babies, along with the complications linked to severe cases of preeclampsia and eclampsia, within a tertiary healthcare facility situated in South India. : Sixty-five pregnant women diagnosed with severe preeclampsia or eclampsia were enrolled in this descriptive observational study conducted at a tertiary care teaching hospital, Chennai, spanning from March 2023 to December 2023. Inclusion criteria comprised women with singleton pregnancies exhibiting severe preeclampsia (defined by blood pressure ≥160/110 mmHg and 1+ or more albuminuria) or eclampsia. Exclusion criteria included chronic hypertension, multiple pregnancies, chronic renal disease, connective tissue disorder, neurological complications, and refusal of consent. Data on sociodemographic variables, obstetric characteristics, maternal symptoms, and complications were collected using a structured questionnaire. Maternal and fetal well-being were assessed through biochemical, radiological, and nonstress tests.: The results revealed that 80% of the study population with severe preeclampsia or eclampsia fell within the age group of 21-30 years, with 49.2% aged between 26-30 years. Majority (60%) were primigravida. Common maternal symptoms included headache (60%), oedema (76.9%), with fewer experiencing epigastric pain (3.1%) and vaginal bleeding (15.4%). Complications observed were HELLP syndrome (12.35%), placental abruption (7.7%), and eclampsia (10.8%). Perinatal outcomes included intrauterine fetal death (4.6%), fetal growth retardation (23.1%), low birth weight (30.8%), respiratory distress syndrome (4.6%), and stillbirth (1.5%), with 35.4% being normal births.This study emphasises the substantial impact of severe preeclampsia and eclampsia on the health of both mothers and fetuses, underscoring the importance of thorough antenatal care, prompt identification of risk factors, and timely interventions to minimise negative consequences. There is a clear call for additional research to investigate and implement effective strategies for prevention and management, aiming to decrease the morbidity and mortality rates associated with these hypertensive disorders during pregnancy.

Published: November 2024

The article systematizes scientific developments concerning the design and reconstruction of railway lines to the European track gauge of 1435 mm. Drawing on the experience of European countries, the study investigates the conditions under which it is feasible to implement a project solution involving the reconstruction of a double-track section into two single-track sections with different gauges: one track remains at 1520 mm, while the other is converted to 1435 mm. The research was conducted using graph-analytical modeling methods. The methodology involves the use of a developed mathematical model that allows for evaluating different scenarios of line capacity using transportation mastery graphs. The study forecasts transportation volumes under pessimistic, rational, and optimistic scenarios, under which the reconstruction of a double-track section into two single-track sections with gauges of 1435 mm and 1520 mm may be justified. A scientific approach is proposed, enabling the evaluation of various capacity scenarios for two single-track sections with gauges of 1520 mm (existing) and 1435 mm (reconstructed), using graph-analytical modeling methods. Based on the results of domestic and foreign scientific developments, potential solutions are outlined for the construction of European standard railways in Ukraine, considering existing infrastructure, geopolitical, topographical, and other conditions. The advantages of this solution include cost savings (as one track does not need to be rebuilt), maintaining connections with countries that use the 1520 mm gauge, and the ability to organize train movements with different track gauges.
“EMOTIONAL PERFORMANCES” IN ANCIENT GREECE: THE MOURNING THROUGHTHE BODY (8TH-5TH CENTURIES B.C.)
Authors: Jourdan Camila 
Published: November 2024

Pain and the grieving process for men and women demand a transformation of the body: crying, chanting the funeral lamentation, getting dirty and cutting hair are part of a social presentation of mourning for the deceased. Considering these issues and having in mind a History of Emotions, we propose a reflection on the “emotional performance” in funeral contexts, with emphasis on the speeches and practices of imputating of mourning in the visual sphere, that is, the transformation of their bodies before society. In this article we analyze the Homeric epics and list some tragedies in order to understand the mourning behavior of men and women in Hellas and their relationship with the body as a vector of an “emotional performance”.

Improbidade administrativa e retroatividade benéfica. anotações críticas sobre o ARE 843989
Authors: Pereira Nobre Junior Edilson 
Published: November 2024

One of the recent significant impacts on the Brazilian legal system occurred with the enactment of Law N. 14,230/2021, which promoted, to a great extent, changes in Law No. 8,429/1992, which regulates the liability of public officials for administative improbity. In view of such changes, the Federal Supreme Court, in a binding precedent (ARE 843989), assessed the incidence of beneficial retroactivity with regard to the exclusion of fault in the strict sense as a subject element for the characterization of the types of administrative improbity and the new discipline of limitation. The purpose of this text is to examine the reasoning employed by the Supreme Court to resolve the issue, discussing the legal nature of administrative improbity, the scope of the fundamental right provided for in Article 5, XL, of the 1988 Constitution, and on the application of the principles of criminal law to administrative sanctions. Not forgetting to mention the exam of legal certainty in the face of the statute of limitation.
Innovative Approaches for Oil Pit Sludge Treatment to Enhance Environmental Sustainability in Oil and Gas Operations
Authors: Alhayem Ahmed A. , Aljamaan Ali M. 
Published: November 2024

Abstract
The efficient management and treatment of sludge accumulated in oily water drainage pits are of paramount importance for oil and gas separation plants, such as Saudi Aramco's Gas-Oil Separation Plants (GOSP). Addressing this challenge requires exploring advanced and environmentally sustainable methods that optimize oil pit treatment processes while minimizing adverse environmental impacts. This study aims to develop innovative and eco-friendly alternatives to conventional oil pit treatment methods. By focusing on enhancing treatment processes, our objective is to significantly improve operational efficiency and reduce environmental risks associated with sludge management in oil and gas facilities.
Our research presents a comprehensive methodology that revolutionizes oil pit treatment practices. Instead of relying on traditional methods involving the construction of temporary pits and manual sludge collection processes, which take significant time and effort and consume huge amounts of resources, we propose an advanced approach. This approach involves the strategic injection of eco-friendly chemicals into existing pits, followed by a series of meticulously designed mixing cycles. These cycles effectively de-sludge and treat the oil, ensuring its safe recovery and reuse within the facility's operational processes.
The implementation of our enhanced oil pit treatment process yields substantial benefits across key operational metrics. Oil recovery rates have experienced a notable increase of 25%, with the current recovery rate standing at an impressive 75% compared to the previous rate of 50% using conventional methods. Moreover, the turnaround time for oil recovery systems has been dramatically reduced by 80%. This improvement allows for the completion of oil pit cleaning activities in a fraction of the time, now achievable within two weeks as opposed to the previous ten weeks required under conventional approaches. These remarkable improvements are achieved through the strategic integration of eco-friendly chemicals, promoting safer and more sustainable practices in oil and gas facility operations.
This study highlights a groundbreaking advancement in oil pit treatment methodologies that harmonize operational efficiency with environmental sustainability. The significant improvements in oil recovery rates, coupled with the drastic reduction in turnaround times, underscore the transformative potential of adopting eco-friendly solutions in oil and gas facility management. By emphasizing the importance of sustainable practices and innovative technologies, this study contributes to a greener and more resilient future for the oil and gas industry

Published: November 2024

Abstract
In our pursuit of excellence reflected in the company's vision 2030, we believe we can drastically reduce waste, prevent major NPT events and reduce risk through data driven improved decision-making. We have seen from NPT event investigations and after-action reviews that understanding risk particularly in situations where cumulative changes occur quickly is an area of improvement. Major events are a result of many minor decisions that have a cumulative impact people did not anticipate or did not accurately forecast and predict. Individuals make the best decisions they can with information readily available, but it is effectively impossible for a human to process all possible variables in well execution. We have leveraged real-time data and analytics to model our operating environment, perform scenario analysis and make the optimal decisions based on defined performance outcomes. This allowed us to make the right decisions on an hour-by-hour basis, monitor the impact of these decisions and adjust in real time.
Courtesy of the digital twin technology, drilling has evolved from passive monitoring and reacting to events to pro-active and predictive collaboration with our rig site teams in identifying NPT events before they happen or before they escalate. A proof of concept was undertaken in partnership with a leading digital twin technology provider in the drilling industry enabled the most informed operational decisions leading to enhanced focus on safety, reduction in NPT and more efficient, reliable, compliant well execution. The outcome enabled predictive data analytical and scenario modelling capability which helped identify problems before they occurred and allowed operational mitigations and/or Subject Matter Expert consultations much quicker than previously possible.
The digital twin technology overcame the common challenges associated with real-time data. These include but not limited to:
Difficulty in seeing negative trend evolution Rearward looking reports – no forecasting Need for continual re-calculation of static models

Radial Multi-Branch Sidetracking Technology for Low Permeability Carbonate Reservoir Stimulation

Published: November 2024

Abstract
To achieve economic and efficient utilization of marginal oil zones and remaining oil zones in low-permeability reservoirs, a directional wellbore stimulation technology with strong targeting and controllability is proposed. This technology integrates drilling, completion, and stimulation functions.
For low-permeability carbonate reservoirs, hydraulic fracturing or acid fracturing are necessary to achieve economically viable development. However, for reservoirs with multiple layers, thin single layers, or those close to edge or bottom water, hydraulic fracturing lacks advantages in targeted and economical modifications and poses significant risks of connecting water channels. A technology is needed that can achieve targeted modifications for multiple layers, with fully controllable modification scope and good economics, integrating drilling, completion, and stimulation. Radial multi-branch sidetracking technology is a drilling-based technique for increasing oil well production.
This technology utilizes magnetic positioning-natural gamma logging tools and gyroscopic inclinometers to determine the depth of casing perforation for radial direction of jet holes. Subsequently, a milling bit is used to create a hole approximately 1 inch in diameter on the casing of the target layer. High-pressure hoses and nozzles are then inserted through continuous tubing, and drilling fluid or acid fluid is injected through a 0.5-inch jet bit. With the hydraulic rock-breaking action of high-speed jets and the dissolution reaction of acid on rocks, multiple radial holes with diameters of 1-3 inches and lengths exceeding 50 meters are drilled in different directions within the reservoir. During implementation, multiple radial holes can be drilled in the same or different layers according to the actual reservoir distribution and production enhancement requirements. This technology offers advantages such as deep-scale damage removal, layered stimulation, three-dimensional digging, physical directional drilling, and avoiding direct connection with edge and bottom water. Moreover, compared to hydraulic fracturing or acid fracturing, it saves significant costs on fluids, equipment, and operations, demonstrating favorable economics.
Field applications have shown that the milling and jetting time for a single branch is only about 1.5 hours, with operation depths exceeding 50 meters. The single branches are distributed in a 60° phase, and the liquid usage for a single branch is only about 10 cubic meters, greatly reducing operational costs. Radial multi-branch sidetracking technology is primarily suitable for oil and gas reservoirs with poor permeability and thin effective thickness, as well as for directed utilization of remaining oil in mature fields and development of marginal oil and gas reservoirs.
Reservoir Characterization of Carbonate Reservoir by Heterogeneity Analysis Using High-Definition Borehole Image & Petrophysical Data of Upper Shuaiba Formation Daleel Field, Oman

Published: November 2024

Abstract
The study's main objective was to conduct a heterogeneity analysis to understand the nature of the complex carbonate reservoirs by integrating geological, and petrophysical parameters to comprehend the different types of facies and their effect on reservoir characteristics. The approach utilizes borehole electrical images to measure the extent and type of the vuggy fraction, porosity dissemination, and its impact on reservoir quality.
The heterogeneity analysis of reservoirs from borehole images is carried out using proprietary software that examines the resistivity spectrum to extract information on porosity, layering and other heterogeneities to quantify, characterize and provide a distribution of these relevant heterogeneities.
Several iterations are needed to optimize parameters. Each iteration is validated by comparing core data, and density-neutron x-plots with a visual examination of the images to see whether all heterogeneities are identified. Single-depth histograms were generated from the derived porosity spectrum to show the distribution of primary and secondary porosity.
The Upper Shuaiba Member (USH) is the main pay zone in the Daleel field in northern Oman and is subdivided into 5 layers comprising of A, B, C, D, and E of which layers D and layer E are the most productive. These layers consist of thinly bedded bioclastic packstones and wackestones. The exploration development of the Daleel field requires knowledge of the composition and collocation of these various layers in the sedimentary system.
Our method consists of several steps that combine a probabilistic image analysis with petrophysical properties to derive electrical facies based on the texture, heterogeneity, resistivity spectrum, fracture identification, and petrophysical properties. These facies are translated into curves, codes and colors that represent the porosity distribution as volume fractions. Primary and secondary porosities (vuggy porosity) are common in this field. We are able to provide color coded distributions showing the more connected vugs, partially connected vugs and isolated or tight vugs. These are separated from connected fractures. This information is critical to developing a geological model to aid field development.
Borehole imagers are important to determine petrophysical parameters in highly heterogeneous carbonate reservoirs. They provide information on a wide variety of pore types including vuggy, fracture and matrix. This study shows that the USH formation contains bimodal and trimodal pores resulting from vugs. All vuggy intervals are classified as connected and unconnected vugs. The results go into a geological model to provide a deeper understanding of the facies extension across the field to optimize exploration.
Maintenance Productivity Advancement by Measuring and Improving HoTT (Hands on Tool Time)
Authors: Jahwari Ali , Hasni Hussain 
Published: November 2024

Abstract
Whilst cost competitiveness becoming a core value, most organizations are stretched toward further means to having more efficient and productive operations. Measuring the time spent by workers while doing the actual work is key to advance productivity. It helps to reveal waste and find better ways of working with direct impact on efficiency and OPEX. Additional value is generated through improved HSSE, better morale, less errors, and quicker return to service.
The time spent by personnel doing the daily maintenance activities called HoTT (Hands on tool time). It is also called wrench time or TOT (time on tools). Three main methods could be used to measure HoTT, Activity Survey, DILO (Day in Life Of) and Self-Reporting. Activity survey is a statistical survey on various maintenance activities. Data points are recorded by observers deployed to random activities. Wrench time accuracy will depend on number of the observations made. The larger the sample size, the more reliable the data would be. The fact that activity survey gives better representation of the studied population, it is considered the most accurate method for HoTT measurement.
Furthermore, DILO day in life of offers a simpler approach by focusing on one maintenance activity. The drawback is less accurate HoTT measurement as less samples will be obtained. Self-reporting is another less commonly used method. It is about asking the worker to report his own HoTT.
In Oil and Gas, best in class facilities are at 60% - 65% HoTT and industry average is around 30% - 40%. Experts emphasize that boosting HoTT to best practice typically increases productivity by 57 percent. For example, a plant might go from fulfilling 500 work orders per month to 785 work orders per month without adding any new technicians to staff.
It is essential to establish a process to measure wrench time, identify waste, generate improvement ideas, and have tracking means to make sure productivity advancement is achieved. In mature organizations where productivity improvement ideas are being realized and sustained, the calculated HoTT would be improving over time.
This paper will discuss different methods to measure HoTT, outline a real case study analysis and showcase the benefits of having a well-established HoTT process in any organization.
