Цель данной статьи – представление результатов изучения возможностей применения искусственного интеллекта в обучении музыке. Анализируются исследования, посвященные проблематике использования искусственного интеллекта в обучении музыке. Осуществляется диссеминация актуального педагогического опыта применения нейросетей в образовательной деятельности. Определяются ключевые направления развития методики обучения музыке с использованием искусственного интеллекта. Ключевой метод исследования – интервьюирование. Сделан вывод о том, что большинству музыкальных педагогов доступны только коммерческие нейросети; использование искусственного интеллекта в образовательном процессе преследует периферийные цели (повышение мотивации учения, развитие художественной культуры, функциональной грамотности). Развитие музыкальных навыков с использованием нейросетей в настоящий момент реализуется в двух направлениях: обучение нотной грамоте и оценка музыкальных навыков.
The purpose of this article is to present the results of studying the possibilities of using artificial intelligence in music teaching. Research on the use of artificial intelligence in music teaching is analyzed. The dissemination of current pedagogical experience in the use of neural networks in educational activities is carried out. The key directions for the development of music teaching methods using artificial intelligence are determined. The key research method is interviewing. It is concluded that most music teachers only have access to commercial neural networks; the use of artificial intelligence in the educational process pursues peripheral goals (increasing motivation to learn, developing artistic culture, functional literacy). The development of musical skills using neural networks is currently being implemented in two directions: teaching musical notation and assessing musical skills.

Case:
A 40-year-old man sustained a traumatic elbow disarticulation without any fracture, accompanied by severe damage of the biceps and brachialis. After replantation, passive elbow motion was used with a hinged external fixator to facilitate elbow joint reduction and mobility. Eight months after the injury, a functional latissimus dorsi transfer for elbow flexion restoration was performed. Ten years postoperatively, he achieved antigravity elbow flexion and 120° of flexion and −15° extension of the elbow.

Conclusion:
This reconstruction technique was useful for reconstructing elbow flexion after traumatic elbow disarticulation.

Published: September 2024

AbstractAccurate estimates of reservoir mole compositions are important for developing accurate fluid models and fluid initialization. However, because of the limitations of the methods used for compositional analysis, a complex mathematical procedure is used to estimate the reservoir from several other measured and estimated properties. The method for compositional analysis has several potential sources of uncertainties, from measurement errors and calculational errors. Compositional variations can have a significant impact on phase behavior calculations, which can have impacts on downstream estimates. Examples of processes that can be impacted include fluid model development, composition initialization (resulting wrong in place estimates), to surface oil volumetric rates. This article systematically introduces the sources of compositional errors for a wide range of fluid types and shows the impact on the phase behavior calculations. Based on this analysis, qualitative guidelines can be made on what compositional uncertainties have the biggest impact on the different fluid types and phase behavior properties.
Experimental Study to Investigate CO2 Mediated Oil Flow in Nanopores

Published: September 2024

AbstractTo optimize CO2 EOR operations, such as Huff and Puff (HnP), it is necessary to have a good understanding of oil- CO2 transport both at nanopore and at reservoir scales. In this study, experiments were performed to investigate how pore adsorbed CO2 can mediate oil flow in analog nanopore arrays. These experiments quantified how much interfacial CO2 contributed to improving permeability to oil in nanopores, in addition to increasing mobility by viscosity reduction. The experimental procedure involved flowing C10 (decane) with and without CO2 through an Anodic Aluminum Oxide (AAO) membrane at a defined differential pressure and recording flow rate. Viscosity obtained from correlations was then used to calculate membrane pore permeability. Inlet pump pressure was lower than the oil-CO2 miscibility pressure at the test conditions. Pore permeability improvement due to pore wall adsorbed CO2 was computed by isolating the effect of viscosity reduction of the bulk fluid. An overall pore-permeability increase of 15% was observed in the CO2 and C10 mixture experiments compared to the C10-only experiments, due to interfacial CO2. These results lend support to the previous molecular dynamics simulations, which predicted that interfacial CO2 can significantly modulate C10 flow in nanopores up to 10 nm diameter (Moh et al. 2020). Some differences from the molecular dynamics simulations of Moh et al. (2020) observed in the experimental study also verify the potential contribution of other phenomena to the permeability enhancement of the nanoporous membrane in the presence of CO2. Therefore, this study provides further impetus for exploring the unique nanofluidic physics of oil and CO2 transport arising from CO2 at oil-wall interfaces. The demonstrated significance of the unique nanopore phenomena, which have not been observed and incorporated into large-scale flow models, emphasizes the importance of identifying and incorporating nanofluidic physics into commercial reservoir simulators' transport models for better representation of CO2 and oil flow in unconventional reservoirs.

Abstract
The historical use of packers in the oil and gas industry has primarily involved elastomers with hydraulic or mechanical operating systems. Bismuth alloy technology offers an alternative material with a distinct operating system. TDAP stands for thermally deformable annulus packer which is a non-traditional seal that aids in sealing leakages in an annulus with Sustained Casing Pressure as a preventative solution before the pressure is observed at the surface.
The technology was developed with extensive lab, yard, and field testing to prove the reliability of this alloy, particularly for larger annulus spaces, such as 9 5/8″ × 13 3/8″. The objective is to proactively eliminate the risk of Sustained Casing Pressure (SCP) in the production and intermediate casing annuli.
The method used to demonstrate this system's applicability involves having bismuth alloy disks on the exterior of one joint of the 9 5/8″ casing. The joint is positioned to achieve the intended depth for the packer. The packer is set above the 13 3/8″ shoe. After cementing, the disks are turned into a liquid using a heater run inside the 9 5/8″ casing. This heater is precisely controlled for temperature and optimized for heat transfer. When the heat source is removed, the bismuth alloy solidifies between the intermediate and production casing, creating a metal-to-metal annulus seal - steel to bismuth alloy to steel. Bismuth has minor expansion properties which give the packer gas tight qualities. To succeed in the field trial, this system underwent testing under full downhole conditions. The setup mimicked the pressure, temperature, casing design, and the medium in which the alloy is set downhole. The test included the heater deployment, the melting of the alloy, and pressure testing of the system up to 5,000 psi in hydraulic pressure.
A unique sealing mechanism of bismuth alloy proactively prevents SAP B. The paper describes the results of the extensive R&D work undertaken, during which the annular bismuth alloy barriers were tested and withstood up to a 5,000-psi pressure differential, having been formed in drilling fluid, clear brine, and cement.
The success of the implementation in the world's largest offshore field will be described. In particular, the innovative well design and deployment of the annular packer to be set in clear brine for maximum pressure integrity with a gas-tight rated seal will be highlighted.
This is the industry's first downhole utilization of bismuth alloys for this size with this application. Its novelty lies not only in the size but also in the engineering required to achieve optimal heat transfer and alloy melting efficiency for such a large size, which entails carefully studying the behavior of this untraditional alloy.

Abstract
The oil and gas industry are under increasing pressure to minimize its environmental footprint, with drilling fluids being a significant contributor to operational emissions and waste. Traditional Oil-Based Muds (OBMs), despite their effectiveness in drilling operations, pose substantial environmental risks due to their disposal challenges and high carbon footprint. In response, High-Performance Water-Based Muds (HPWBMs) have been developed, promising reduced environmental impact and improved performance. This study aims to evaluate the efficacy of HPWBMs in reducing emissions and waste while maintaining operational efficiency and cost-effectiveness. The primary objective of this research is to compare the environmental and economic impacts of HPWBMs and OBMs through comprehensive field trials and laboratory tests. By analyzing drilling performance, cost-per-lateral-foot, waste management, and emissions, this study seeks to establish HPWBM as a viable and sustainable alternative to OBMs in the oil and gas industry.
Field trials were conducted in North Central Texas and the Permian Basin, involving the drilling of 26 wells—13 using HPWBM and 13 using OBM. The North Central Texas case study focused on an operator's challenge of drilling 10,000-15,000’ lateral wells at TVDs of 3,800-4,800’. In the Permian Basin, Wolfcamp horizontal wells were drilled to evaluate performance. Key performance indicators (KPIs) such as drilling fluid cost, lateral cost per foot, and days per well were measured. Emissions were calculated using a carbon calculator, and laboratory tests assessed rheological properties, lubricity, and thermal stability.
The results indicated that HPWBM systems not only reduced drilling costs by 18.2% but also significantly lowered CO2 emissions and hazardous waste generation. In the North Central Texas case study, the use of HPWBM resulted in cost savings of over $100,000 per well, with significant reductions in disposal costs, OBM logistics, base-fluid costs, motor realignment fees, and pit cleaning expenses. The environmental footprint and carbon emissions were notably reduced, with CO2 emissions for HPWBM wells averaging 386.1 metric tons compared to 710 metric tons for OBM wells. In the Permian Basin, the average fluids cost per foot for HPWBM wells was $6.02 compared to $7.04 for OBM wells, and the average number of lateral days was reduced to 4.92 days compared to 11.50 days for OBM wells.
This study presents a comprehensive evaluation of HPWBMs, demonstrating their superior environmental and economic performance over traditional OBMs. The significant reduction in CO2 emissions and hazardous waste, combined with cost savings and improved operational efficiency, highlights the potential of HPWBMs to transform drilling practices in the oil and gas industry. The findings support the broader adoption of HPWBMs, promoting sustainable and cost-effective drilling operations that align with global sustainability goals.
Gas Flow Rate Estimation with Artificial Intelligence: Bridging Reality Through Computer Vision and Machine Learning

Abstract
Flaring in the oil and gas industry is a critical process where excess gases are burned off through a flare stack. This practice is essential for safety reasons, such as pressure relief during unplanned overpressuring of plant equipment, and for managing gases that cannot be processed economically. However, flaring is also a significant source of greenhouse gas emissions, releasing harmful gases such as carbon dioxide and methane into the atmosphere. The environmental impact of these emissions makes it imperative to monitor and control flaring activities effectively.
Despite the necessity of monitoring, the traditional methods involving flowmeters present significant challenges. These devices, which measure the rate of flow of the gas being flared, are often prohibitively expensive and complex to install, especially in remote or offshore locations. This high cost and complexity can hinder comprehensive monitoring efforts, leaving a gap in effective environmental management practices.
Moreover, the practice among oil and gas operators to rotate available flowmeters across different flare stacks further complicates consistent monitoring. This rotation often results in minimal monitoring—sometimes only sufficient to meet the bare minimum of legal reporting requirements. Such practices underscore the need for more robust and continuous monitoring solutions.
To address these challenges, in this paper we explore an innovative approach to estimate flaring emissions using a more accessible and cost-effective technology. By leveraging a simple system composed of a camera and an edge computer, this method uses visual data and advanced computing techniques to estimate the volume of gas flared. This approach not only reduces the economic burden associated with traditional flowmeters but also enhances the feasibility of continuous monitoring across various operational settings in the oil and gas domain. Through this paper, we aim to demonstrate the effectiveness of this system and discuss its potential implications for environmental monitoring and regulatory compliance in the industry.
A Systematic Approach to Interpreting Cement Bond Logs

Published: September 2024

Abstract
To achieve a more consistent and disciplined approach, and to achieve a higher rate of accurate conclusions, a cement bond log interpretation method has been organized and applied to hundreds of operations around the world. This method approaches the bond log from a "cementing perspective" and when applied to previously interpreted logs, resulted in an accuracy increase from approximately 30 % to greater than 90 %. This study of three-hundred and twenty five wells also showed that the most common error was the misinterpretation of logs for wellbore sections containing a microannulus.
This paper details a five-step process, including an example of the numerous observations and decisions that are typically made, and introduces forty-three wellbore effects that may be key to accurate bond log interpretation. Besides accuracy, the vast majority of cement bond logs have been "under-interpreted," lacking important details. This new integrated approach to bond log interpretation is designed to provide a full interpretation, hence the zonal isolation summary, the nature and cause of any cement defects, and recommendations for remediation or future improvements, are all key parts of the final interpretation.
Unveiling the Imprecision in Well Test Data: A Guide to Improve Accuracy of Water Cut Measurement
Authors: Rois Muhammad Amin 
Published: September 2024

Abstract
Well test in Banyu Urip (BU) field employs 2-phase Test Separator equipped with Coriolis Meters to measure gross liquid rate and density for water cut calculation. As BU matures, obtaining water cut data during well test is crucial for well surveillance and scale management. However, there are challenges to precisely and accurately measure water cut as it evolves. This paper shares insights to improve precision and accuracy of water cut measurement during well test.
The well test accuracy is validated by comparing produced water (PW) rate from process flow meter at Primary Separators with those derived from Coriolis Meter at Test Separator. The process flow meter's accuracy is ensured through range adjustments following actual rate. In early year, water cut data from Coriolis Meter was inaccurate as indicated by significant PW balance gap. This finding prompted investigation through High-Pressure High-Temperature (HPHT) test analysis, collaboration with manufacturer, and process simulation. Lab test emerged as the primary method to measure water cut by manual sampling at inlet Coriolis Meter during well test.
Upon increasing PW rate, discrepancies between PW rate derived from well test manual sampling and process flow meters showed an upswing, reaching 27% gap. This swing was mainly caused by inconsistency in obtaining homogenous oil-water mixture from sampling branch. Hence, examination of Coriolis Meter's accuracy was imperative as it can precisely capture representative sample.
An investigation uncovered gas entrainment in preserved liquid sample by testing it in HPHT. The gas lowered actual density from Coriolis Meter below than reference density at the same pressure and temperature, resulting into significant PW balance gap during low water cut operation. Two potential root causes were identified: gas carry under and gas flashing. Vessel sizing verification confirmed adequacy of existing Test Separator in preventing gas carry under, leading to conclusion that gas flashing due to friction loss was the root cause.
To address this, the water cut calculation was modified by incorporating an empirical correction factor for gas entrainment, including operation strategy to minimize it. This proved pivotal to improve well test accuracy, reducing PW balance gap to 5%. The improved PW rate precision and accuracy contributed to benefits for well allocation, Voidage Replacement Ratio management, and scale inhibitor effectiveness.
Typical gas entrainment issue can be found at liquid leaving separator in saturated condition, thus effecting meter accuracy. Adjusting liquid level upwards can mitigate gas flashing by providing additional static head to compensate friction loss. However, this poses the risk of high-high liquid level trip, especially for slugging well. Therefore, addressing gas entrainment issue by good Test Separator operation strategy and reliable water cut calculation is critical to get accurate and precise well test data.
Advanced Downhole Flow Detection through Acoustic and Temperature Sensing in Combination with Geochemical Testing; A holistic Approach

Abstract
As the need for energy increases, drilling and completion of new deep natural gas wells is also increasing. Commonly, gas wells are monitored through real-time surface readings. Government regulations and environmental considerations mandate the safe operation of all producing assets. A measure of well health is the annuli readings. Normally, each outer casing annulus should read zero pressure. However, due to a number of factors, the annuli can sometimes exhibit positive pressure. Once a well exhibits abnormal annuli pressures, it must be investigated and actioned accordingly. As the casings can cover a long section of footage, it is necessary to run a downhole detection tool to identify the fluid flow. This paper describes the best practices to detect fluid outflow through temperature and acoustic logging in combination with geochemical laboratory testing and provides field applications.
Conventional bleed-off/build-up cycles are used to check the sustainability of the pressure build-up in the annuli. Once that pressure is confirmed to be sustainable, a slim downhole tool conveying high-definition spectral noise and temperature sensors is run to determine the fluid flow location. The high-definition acoustic survey is conducted on the stations using a wide frequency range acoustic sensing platform that can record within a 15 ft radius of investigation. The acoustic survey produces a high-definition power spectrum that can reveal and characterize flow activity within the well system, including the tiniest of noises generated by fluid movement. This was combined with high-precision temperature surveys and analysis.
To identify the feeding zone, fluid is sampled via pressurized cylinders at the surface and dispatched to a laboratory for geochemical isotopic fingerprinting analysis. Carbon isotopes were measured using gas chromatography connected to an isotope ratio mass spectrometer.
Downhole logging composed of High Precision Temperature and High-definition Spectral Noise Logging was combined with surface pressure reading analysis to provide a complete assessment of the casing fluid outflow. Logging showed clear signs of downhole fluid movement while gas isotope analysis identified sample origin. Carbon isotope compositions were compared to other endmembers. Carbon isotopic profile plots were used to fingerprint the origin of the moving fluid.
The novel suggested methodology and procedure of downhole fluid movement detection in combination with geochemical testing provides comprehensive and highly accurate analysis that helps to reveal the truth of fluid movement and enables for fit for purpose preventative workover operation.
