Technology Focus: Acidizing (June 2024)
Authors: Abbasy Imran 
Published: June 2024

Industry continues to struggle with acid distribution and penetration. Most papers, therefore, continue to focus on these themes. Other than recommendations for further reading, a few other papers are worthy of mention and may provide some useful tools for the practicing engineer.
Paper SPE 214416 describes a novel technique that could perhaps be developed further. The concept is built around running a tool on wireline across the zone of interest, which, upon activation, generates hot acid vapor. The procedure is simple, bearing a low cost with no associated environmental hazards. Engineers desperately need an alternative to acid placement through pipe, coiled tubing, or bullheading. For example, propellants have been around for years; however, their performance has not quite met the hype. Nevertheless, several case histories have been authored to suggest their efficacy; historically, some treatments have even been wildly successful. The point is, more effort is needed to mature techniques such as these as an alternative to conventional stimulation.
In paper URTEC 3818857, an oxidizer is introduced as a preflush to improve near-wellbore conductivity without adding significant cost and operational complexity. The oxidizer was effective in removing biological debris and biofilms, thereby improving acid penetration. Paper SPE 215664 examines the use of biodegradable particles and fibers to divert in naturally fractured carbonates. Size distribution was the key to achieving temporary isolation with a minimal amount of material. In fact, the paper showcases successful treatments with less than one barrel of this material. Furthermore, no material was recovered during flowback, indicating complete degradation.
Lastly, SPE 216144 introduces a novel automated framework that relies on smart sampling and tests multiple scenarios to arrive at an optimal stimulation design. The process is intelligent and entirely Web-based.
Acid stimulation is indispensable, and the understanding of fluid systems, and the placement thereof, continues to evolve.

Technology Focus: Hydraulic Fracturing Operations (June 2024)
Authors: Pandey Vibhas 
Published: June 2024

Hydraulic fracturing continues to be one of the popular stimulation techniques employed to enhance production from oil and gas wells worldwide. The application of this technique in both conventional and unconventional reservoirs has resulted in improved hydrocarbon recovery from several oil and gas reserves worldwide.
The authors of paper SPE 217813 discuss the use of far-field diverters as a technique to protect parent wells from the detrimental effects of fracture-driven interactions when fracture-stimulating infill wells. Various case histories of the wells drilled and completed in the Bakken and Three Fork formations are presented in the paper. The authors observe that most infill wells under study exhibited superior or comparable year-long production behavior when compared with offset parent wells and also resulted in fewer wellbore cleanouts in some of the parent wells. The authors also note that effectiveness of such treatments depends on formation characteristics and wellbore production history.
Paper SPE 213110 presents the observed benefits of fracture-stimulating a high-viscosity oil-bearing formation that was earlier classified as a secondary target in the Apaika-Nenke oilfield in Ecuador. The authors provide a detailed description of reservoir, geology, and pressure/volume/temperature properties, along with modeling workflows adopted to maximize the benefits of stimulating low-API and highly viscous oil-bearing formations that resulted in improved well performance in comparison to unstimulated cases.
In paper SPE 215705, the authors present the introduction of hydraulic fracturing on initially unstimulated wells completed in low-permeability oil-bearing formations in North Africa. The authors report a multifold increase in well production after fracture stimulation from the formations that have been producing for a long time after initial well completion that did not include well stimulation. The authors emphasize that the potential to improve well performance with fracture-stimulation treatments must be pursued despite challenges offered by wellbore architecture.

Far-Field Diverters Protect Parent-Well Production in Unconventional Wells
Authors: Carpenter Chris 
Published: June 2024

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 217813, “Protecting Parent-Well Production Using Far-Field Diverters in Unconventional Wells,” by Foluke O. Ajisafe, SPE, Liberty Energy, and Hank Porter, SPE, and Sunny Kothare, Lime Rock Resources, et al. The paper has not been peer reviewed.

_
The effect of fracture-driven interaction (FDI) is an increasing concern in mature developed unconventional plays in the US. In this study, parent-well production performance after infill-well stimulation is evaluated to understand the effectiveness of a far-field diverter in mitigating FDIs. Studies to determine whether FDIs result in a negative or positive effect have concluded that the effect varies from basin to basin. In this project, the purpose of pumping the far-field diverter is to mitigate wellbore sanding and production loss in existing parent wells.

Introduction
The operator in this study is active in the Bakken and Three Forks formation in the Williston Basin and had experienced the negative effect of FDIs. These can occur because of close well spacing and large fluid and proppant volumes and can be exacerbated by reservoir pressure depletion caused by production. In the project described in the complete paper, pressure depletion is the main driver for fracture hits to the parent wells. Most of the parent wells have been in production for years before infill-well drilling and completion. The main goal is to maximize production of parent and infill wells and avoid sanding the parent well by decreasing the frequency and severity of fracture hits to parent wells. To combat this issue, operators have tried several solutions, such as optimized well spacing and treatment designs, repressurization, and even refracturing, with mixed results. A cost-effective solution with simpler operational logistics, the use of a far-field diverter was considered to create more complexity and reduce the occurrence of extended fracture geometry toward the depleted zone or region. The far-field diverter pill is a mixture of materials transported to the tip of the fracture, where they bridge and create a low-permeability plug for fracture geometry control to mitigate FDIs.
The complete paper provides a history of the operator’s experience with the use of far-field diverters.

Current Work Scope
Since 2019, multiple infill (child) wells have been completed, and far-field diverters implemented, to mitigate fracture hits to offset parent wells. Extensive work was completed in eight different well pads (Pad A through Pad H) across three different counties, Dunn, Mountrail, and McKenzie. The far-field diverter pill was pumped in 25 horizontal wells landed in both the Middle Bakken and Three Forks formations. The main objective of this study was to investigate the production effect on parent wells after the use of far-field diverter on the infill wells.
Optimal leakage detection and classification of the water distribution network based on the machine learning approach

Published: June 2024

ABSTRACT

Water distribution networks are operated to supply tap water stably, but they suffer from leakage due to various factors, resulting in poor performance. In Korea, IoT (Internet of Things)-based smart sensors are installed to reduce these leaks, and a large amount of data is collected. In this study, to solve the data uncertainty and verification of the model's field applicability, the eXtreme Gradient Boosting (XGBoost) model, which is based on boosting, was selected. This choice was made through hyperparameter optimization using leak detection data obtained from leak detection sensors, as well as data refined through on-site leak detection. The area under the curve_receiver operating characteristic value for each leak class using the XGB model was 0.9955 for class 0, 0.9956 for class 1, and 0.9985 for class 2. In addition, the partial dependence plot of 120 Hz, which has the highest variable importance, was derived from analyzing the influence of the leak detection and classification model on the amount of leak vibration change at 120 Hz. Therefore, it is expectged the suggested methods can be used to build a GIS-based monitoring system for real-time leak detection by linking the developed model and the location of the leak detection sensor.
Untangling Sudan’s Discord: Decrypting the Intricate Threads of Turmoil
Authors: Afriyie Frederick Appiah 
Published: June 2024

The conflict in Sudan between its military forces and a rival paramilitary group, exacerbated by allied militias, has escalated into a dire humanitarian crisis, reminiscent of past civil wars where hundreds of thousands perished. This ongoing struggle, marked by thousands of casualties and millions displaced, centers on a power struggle between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF), with global powers seeking to influence the outcome. Despite initial hopes for democracy following the ousting of former dictator Omar al-Bashir in 2019, political turmoil ensued, culminating in a failed transitional government and the assumption of power by General Abdel Fattah al-Burhan. Despite agreements aimed at civilian-led transition, missed deadlines and the contentious integration of the RSF into the national armed forces perpetuate the conflict. Amidst this turmoil, international sanctions target entities funding the conflict, such as Alkhaleej Bank, Al-Fakher Advanced Works, and Zadna International, among others, reflecting broader efforts to disrupt funding sources and facilitate a democratic transition. In this context, this research delves into the underlying factors driving the conflict in Sudan.

Published: June 2024

Implantation via an intercalary prosthetic method is a reliable solution for reconstructing a long defect in bones that has been damaged by severe disease or accidents. In the current study, using data from computed tomography (CT) scans, a novel costumed intercalary prosthesis design has been created. To achieve this purpose, the CT scan data of a patient in (DICOM) file format was converted into computer-aided design models and saved in stereolithography (STL) format using the 3D slicer (5.0.3) software. The STL files were loaded into Meshmixer software to design the models of the intercalary prosthesis. Finite element analysis (FEA) was applied to validate the strength of the prosthesis with impact, tensile testing, and torsional testing. According to the results of the impact tests, the highest recorded deformation was 8.8485e-002 m in the area where the implant body interfaces with the bone intramedullary canal, due to the high-stress (Von Mises Stress) value of 3.78 E9 PA. In the torsional loaded the highest deformation recorded was 1.3871e-008 m when the Von Mises stress reached 49006 PA, and with the application of the tensile test the largest deformation measured as 1.0458e-006 m at maximum Von Mises stress seen was recorded as 6.6012e+006 PA which caused that. A solid rod of Ti6Al4V alloy was selected. Finally, the analysis proved that the implant had enhanced mechanical properties. Based on the findings, it can be inferred that the prosthesis was successfully implanted, and a satisfactory result was obtained by using this design method.

Objective: The present study was carried out with three varieties (green, pink, and sweet) of Carissa carandas fruit extract for the identification of phytochemical constituents in C. carandas fruit extracts using Liquid Chromatography-Mass Spectrometry (LC-MS/MS) and Gas Chromatography-Mass Spectrometry (GCMS)
Methods: LC MS/MS and GCMS analysis were adopted to study three varieties of C. carandas fruit, namely green, pink, and sweet, using different solvent extractions such as ethanol, methanol, and aqueous.
Results: High levels of phenolic acids and flavonoids in the green variety were beneficial for anti-diabetic activity due to their antioxidant properties. Among the three varieties of tested samples, the maximum concentration was observed in the ethanol extract of the green varieties (2.485 mg/g FW) compared to the ethanol extract of the pink (1.564 mg/g FW) and sweet (1.285 mg/g) varieties, respectively. Ethanol extract of the green variety has a high level of anthocyanin, which increases tolerance to disease. The separation and identification of fatty acids in C. carandas fruit were determined through analysis. The sweet C. carandas variety recorded the highest concentration of fatty acids (147.2 mg/100g FW) compared to the pink and green varieties (94.9 mg/100 g FW) and (72.79 mg/100 g FW), respectively, and could successfully identify the number of phytonutrients that have health benefits. Further work is being carried out, which may lead to the development of herbal medicine.
Conclusion: The present study concludes that phytochemicals present in C. carandas fruit, extracted by LC-MS and GC MS analysis, contain antioxidant and anti-diabetic effects.

Authors: Krakowiak-Burdzy Anna Barbara , Fąfara Anna 
Published: June 2024

Abstract

Introduction. Consumerism refers to people who adopt attitudes characterised by unnecessary consumption and excessive accumulation of material goods, which are the most important, essential in life, and are a determinant of quality. Consumerism has brought noticeable positive effects in the area of health services due to the observance of patients’ rights, the provision of ever higher quality medical services, allowing the patient to decide on certain issues concerning their life and health, and the choice of doctor or medical facility.

Aim. The aim of the work was to analyze the scientific literature on consumerism in health care.

Method. Scopus, PubMed databases and Google Scholar were searched in accordance with the guidelines of Preferred Reporting Items for Systematic Reviews and Meta Analyzes (PRISMA 2020).Ultimately, 14 articles that met the inclusion criteria were included for detailed analysis.

Results. Comprehensive, high-quality nursing care in a hospital, upgrading the skills of health care professionals and appropriate behaviour of medical staff contribute to the positive assessment of a particular facility, and thus attract other customers (patients) to use medical services.
