Published: February 2024

Abstract
Fresh water resources are increasingly becoming scarce, which is a concerning matter due to the rapid growth in global human population, industrialization and pollution of fresh water sources and underground aquifers. Therefore, utilizing water treatment technologies in water intense processes such as oil and gas production and increasing the industries’ water efficiency have become ever so important. Produced water (PW) from oilfields is the largest waste stream in the oil and gas industry, and the quantities of PW globally has been recorded at more than 250 million barrels per day. The purification of this large amount of by-product by means of ceramic membrane filtration has been investigated in this study with samples from an oilfield in the State of Kuwait with a reservoir containing mostly heavy oil and a high H2S content. The sampled PW originates from an oilfield with approximately 80 percent water cut. PW has a number of components that cause production problems such as scaling and corrosion. Therefore, the treatment of PW before its disposal or reuse is seen to be urgent. Discharging this water to the environment can also lead to severe environmental impact. Therefore, rigorous regulatory standards have been implemented for the disposal of PW into the environment, which are a significant challenge to the oil and gas industry. The understanding of the characteristics and the treatment of PW can avoid the degradation of production facilities and equipment and consequently lower the maintenance costs at the production sites. In this study, the PW samples were filtered using a φ30/100mmL ceramic membrane element with a nominal pore size of 0.1μm.

Published: February 2024

Abstract
Retarded HCl acid treatment has been used as an effective method for enhancing hydrocarbons production from carbonate reservoirs by creating highly conductive channels. A thorough understanding of performance of the retarded HCl additives is essential to prevent or minimize incompatibility of acidizing additives in the treatment. The objective of this work is to highlight the effect of retarded HCl recipe additives (e.g. H2S scavenger) on corrosion rate and compare it to regular HCl recipes. The paper additionally discuss typical testing conducted with carbonate acidizing acid recipes to assess performance.
HCl acid and inorganic/organic acid retarded agents were obtained for this study. Typical experimental testing were conducted to assess acid recipes includes (1) thermal compatibility up to 300°F to identify precipitation or sludge formation, (2) iron control testing to assess the capacity of the acid to keep iron in solution at pH of 4 up to 300°F, and (3) coreflood and CT scan testing to assess wormhole formation profile and precipitation. XRD, TGA, ESEM, and NMR experiments were conducted to analyze solids and precipitation. An autoclave reactor was used to conduct corrosion testing to assess the effect of acid recipe additives on the corrosion rate up to 300°F.
The effect of acid additives on the corrosion rate of 15 wt% retarded HCl acid with divalent salt and chemical retarder was investigated. It has been observed that the use of H2S scavenger with the retarded acid recipes resulted in significant increase in corrosion rate from 0.05 to 0.10 lb/ft2. The corrosion testing results indicated the EDTA-based chelating agent slightly increased the corrosion rate of the retarded acid recipe. However, the significant increase in corrosion rate was due to the presence of H2S scavenger and large amount of MgCl2 in the HCl recipe. H2S scavenger can be used in this retarded acid recipe. Alternatively, during acidizing operation of H2S scavenger pill can be used as spacers before and the pumping of the retarded acid.

Abstract
Organic-rich shales have gained significant importance as an abundant source of natural gas and oil. Kerogen maturation can be induced by altering the temperature and pressure conditions over time. This study explores the effects of carbon dioxide injection on kerogen maturation in unconventional shale resources, examining its effects on petrophysical, geochemical parameters, and hydrocarbon productivity. Three types of organic-rich unconventional shales were used to study the effects of artificial maturation. Artificial maturation, aided by CO2, significantly reduced total organic content by (10-40%) and improved rock porosity and permeability due to microfractures induced. The study found significant increases in free hydrocarbon volume (S1) and potentially produced hydrocarbons (S2) in different samples, with slight changes in other geochemical parameters like hydrogen index and sulfur content.
Ultimately, this study proposes a method for improving the potential for oil and gas production through kerogen maturation. Using CO2 as an inducement for the maturation of organic-rich shale has shown promising results in accelerating the process while also having the potential to sequester CO2 due to its high affinity for adsorption in shale formations. Furthermore, the use of CO2 as an inducement could lead to more efficient hydrocarbon recovery compared to common maturation processes, as it enhances shale gas production by increasing kerogen thermal cracking.

Abstract
Oil and gas production operations are key sources of environmental pollution which exposing the people and effect the human activity in the world. Petroleum Development Oman (PDO) is the leading exploration and production oil and gas companies in the Sultanate of Oman which lead to avoid adverse health effects in Oman. Oil leaking detecting in a timely that leaking could be undetected for long time. However, the precise methods could help improving the oil leaking detecting response process in channel required resources with more effectively to be concerned regions. Existing Synthetic-aperture radar (SAR) approaches are limited by their algorithm complexity which difficult to work with imbalanced data sets, doubts to select optimal features, and the relatively slow detection. Using deep learning approach could speed up the oil detection. convolutional neural network U-Net segmentation models based on oil leaking detection could be achieve promising automated results. However, there are insufficient features extraction due to loss of target to detect oil leaking or shadows in drone images that commonly appear in various size ,shapes and brightness levels, which the images that captured under many conditions. To overcome all these limitations, we improved deep learning model named Pyramid Scene Parsing Network (PSP Net). The proposed algorithm can probabilistically detect when and where a leak is taking place and can segment from shadow noise images at the frequency of data collection. Thus, PDO Oman could reduce millions of Dollars when direct action from operators that received a quick true alarm of oil leaking. The effectiveness of the proposed algorithm is demonstrated through A proof of concept (POC) based on a realistic dataset that collected history data that our deep learning algorithms achieved the perfect predict the oil leaking before occurs.

Development of an environmentally acceptable KHI with comparable performance that is not affected by continuous corrosion inhibitor, and compatible in high saline, elevated temperature systems bring further opportunities for KHI globally.
A Cross-Sectional Study of Etiology and Clinico-Hematological Profile of Pancytopenia in Children at Tertiary Care Centre in Western India
Authors: Kale Anjali , Idhate Tushar , Reddy Rishivardhan 
Published: February 2024

Objectives
Pancytopenia is one of the most common blood disorders observed in routine clinical practice. There are few studies analyzing pancytopenia in Indian scenarios. This cross-sectional study is aimed to identify the cause of pancytopenia and analyze the clinico-hematological characteristics of children with pancytopenia in Western India. So this study was conducted to evaluate clinico-hematological profile of children presenting with pancytopenia and to determine the etiology of pancytopenia in Western India.

Material and Methods
This two-year descriptive cross-sectional study was conducted in a tertiary care referral hospital. All children with pancytopenia, ranging in age from 1 month to 18 years, were enrolled in the study. A thorough history was taken, as well as general and systemic examination findings, hematological parameters, and bone marrow examination findings were recorded.

Results
The age group of enrolled patients ranged from 1 month to 18 years in the 130 cases evaluated (63 males and 67 females), while the mean age was 9.8 years. Fever was the most prevalent symptom (n = 111, 85.40%), followed by generalized weakness and weight loss. Pallor was the most common physical manifestation, followed by knuckle pigmentation, hepatomegaly, and splenomegaly. Study results concluded that the most common cause of pancytopenia was megaloblastic anemia, followed by acute leukemia, aplastic anemia, and infections. Megaloblastic anemia can be distinguished from other causes of pancytopenia based on dietary habits, hematological parameters and serum B12 levels, potentially obviating the necessity for a bone marrow test in most pancytopenia patients.

Conclusion
In pancytopenia patients, detailed initial hematological investigations, including bone marrow examination, are beneficial for correct diagnosis. Although megaloblastic anemia is the most prevalent cause, other factors to examine include aplastic anemia, leukemia, Hemophagocytic Lymphohistiocytosis (HLH), hypersplenism, Systemic Lupus Erythematosus (SLE), and viral infections. When a complete history, clinical examination, and baseline hematological parameters are adequately assessed, bone marrow examination can be avoided in most pancytopenia patients.

Компанії, які прагнуть вижити в надзвичайно конкурентному середовищі, мають трансформувати свої процеси стратегічного планування, щоб вони були більш постійними, гнучкими та ефективними. Зараз неможливо створити виграшну стратегію без інновацій.
З проведеного огляду можна зробити висновок, що стратегічний напрям інновацій значною мірою залежить від високих ієрархічних рівнів, які повинні мати необхідні інструменти для формулювання та реалізації інноваційної стратегії. Запропонована модель управління полегшує для менеджерів соціалізацію стратегії, а також надає можливість усім залученим учасникам контекстуалізувати те, що формується в щоденних діях, досліджуючи та експериментуючи, незважаючи на ризики інновацій. Крім того, шляхом формалізації процесу управління інноваціями в структурі цих компаній створюється більша прихильність та інтеграція різних функціональних сфер, завдяки чому досягається гармонізація діяльності, щоб спочатку запропоновані цілі могли бути досягнуті спільно.
Картування завдань суттєво відрізняється від картографування процесів тим, що мета полягає у визначенні того, що клієнти намагаються зробити на кожному кроці, а не того, що вони зараз роблять. У кожному окремому етапі є кілька можливостей зробити роботу простішою, легшою або її пришвидшити. Плануючи кожен етап роботи та знаходячи ці можливості, компанії можуть знайти нові шляхи диференціації своїх пропозицій. Це має бути включено в процес стратегічного планування, щоб можна було розробляти стратегії, які подовжують термін корисного використання поточної бізнес-моделі, а також вивчати нові, які дозволять скласти середньо- та довгострокову інноваційну карту розвитку компанії.
Violencia obstétrica en Colombia y España: un delito sin ley
Authors: Marco Mingueza Elena 
Published: February 2024

Introducción: la violencia obstetrica (VO) es una problemática social presente en todos los países del mundo. Territorios como Colombia o España, pese a su gran diferencia sociocultural, no enmarcan la VO como concepto en su legislación, ni aceptan su inclusión como una rama de la violencia de género. Mediante la revisión bibliográfica se observan algunas causas de la VO que presentan una gran falta de veracidad, mientras se omiten otras muy prevalentes en los dos países, poco cautivadoras para el interés médico.
Reflexión: las opiniones de los profesionales acerca de la VO son muy dispares, como se observa con el testimonio de un ginecólogo colombiano y una matrona española. Organizaciones médicas como la Federación Colombiana de Obstetricia y Ginecología (FECOLSOG) en Colombia o el Consejo General de Colegios Oficiales de Médicos (CGCOM) en España se han opuesto mediante comunicados oficiales con argumentos irreales y poco verídicos, responsabilizando a las instituciones y fomentando la impunidad médica. Se menciona a la VO como una innecesaria alarma social y no como un verdadero problema de salud pública y su influencia a nivel mundial. Conclusiones: las causas estudiadas de la VO tienen mucha falta de credibilidad después de una comparativa internacional. Multitud de estudios se ven sesgados por la falta de información de este suceso, dificultando la visibilización de la VO y su estudio. Se requiere una correcta formación del profesional sanitario, una intervención educativa para las mujeres acerca de la VO y su inclusión en la legislación para poder convertir su práctica en una grave vulneración de los derechos humanos de la mujer.

Authors: Sierra Amoedo Alejando 
Published: February 2024

El propósito de la presente investigación radica en llevar a cabo un análisis de la eficacia en el uso de estéticas de género no binario en el contexto del comercio electrónico, con la finalidad de atraer y satisfacer a una extensa y diversificada clientela compuesta por individuos de ambos sexos.
La metodología empleada se fundamenta en un enfoque de estudio de caso, en el que se procedió a la creación de una marca de ropa y, subsiguientemente, a la implementación de una plataforma de venta en línea, diseñada de manera que los productos fueran presentados de forma no binaria, eliminando así la segregación convencional basada en las categorías de hombre y mujer.
El análisis de los resultados, obtenidos a partir de una muestra representativa compuesta por 14 mil usuarios, recopilada durante un año, abarcando el período desde el 01/10/2021 hasta el 01/10/2022, proporciona las primeras indicaciones de que no resulta imperativa la segregación de los productos por género, siempre y cuando estos sean debidamente representados para acomodar a diversas morfologías. Además de este hallazgo, es oportuno destacar que los compradores receptivos no se limitan exclusivamente a usuarios jóvenes o a aquellos que se identifican como género no binario. En efecto, la experiencia de compra se revela igualmente intuitiva entre compradores de todos los géneros e, incluso, más popular en aquellos con edades comprendidas entre los 45 y los 65 años.
