Authors: Fei Zhao , Depeng Jia
Published: June 2024

In recent years, Chinese high-tech enterprises have been experiencing a period of rapid development. Their scale and quantity have surpassed the figures of some developed countries in the world, and their share in the modern market structure has also increased. Discussing the characteristics of managing high-tech enterprises and managerial measures can not only help enhance the core competitiveness of these enterprises and establish their competitive advantages but also play a positive role in promoting market economy reforms. In the presented study, the author identifies the peculiarities of internal management in Chinese high-tech enterprises. Additionally, the article highlights issues in the management of high-tech enterprises and proposes measures for the improvement of management within this sector of the economy.

Published: June 2024

The objective of this study is to determine the degree of influence exerted by the Federal Reserve System (FRS) interest rate hike in the United States on global markets, including the Russian market. To achieve the research objective, both quantitative methods (statistical regression analysis) and qualitative methods (document analysis and expert interviews) were utilized. The findings of the study revealed a significant level of influence from changes in the banking and financial system of the United States on global markets. To mitigate the negative consequences, the creation of an alternative global reserve currency fund is proposed, with the yuan being the most suitable currency for this purpose. The scientific novelty of the research is justified by the fact that economic interdependencies between countries are becoming increasingly interconnected and interdependent. The increase in the FRS interest rate can have a substantial impact on the economic situation in various countries worldwide, including both developing and developed economies. Previous studies on the impact of FRS interest rate hikes on global markets were conducted during different time periods and under various economic conditions. However, in light of recent events such as the COVID-19 pandemic and global trade disputes, changes in market reactions to FRS interest rate hikes are possible.

Published: June 2024

Within the context of the rapid expansion of globalization processes throughout the global economy, the most significant trend of this process is the emergence of transnational corporations. The main research methods used in this study were theoretical (analysis, synthesis, induction), empirical, and interpretation of expert opinions on this issue. The management of export-import operations of transnational corporations remains relevant and important for businesses. However, the process of managing export-import operations can be quite complex and requires significant efforts from companies to properly execute all necessary procedures. Specifically, companies need to ensure proper documentation, accurate assessment of goods and services, as well as timely delivery. Additionally, companies need to plan and manage cash flows correctly to ensure the safety and efficiency of operations. All these processes require a professional approach and specific knowledge and skills. Currently, differences in political and economic stability of states, legal and regulatory systems, and established "rules of the game" in organizing and conducting business become particularly acute.Therefore, the goal of this article is to form or continually improve combined approaches to the development of corporate activities, which will cover not only the advantages of the global economy but also the peculiarities of local markets.

Authors: Korobov Sergey , Epinina Veronika , Moseyko Victor , Usacheva Irina
Published: June 2024

The study aims to substantiate and prove the feasibility of the cognitive approach in determining the role and impact of available resources to ensure the competitive functioning of small and medium-sized businesses. The authors have developed a toolkit for implementing the competitive functioning of small and medium enterprises through resource and factor support within the framework of the cognitive approach, acting as a methodological basis and applied in the implementation of expert analysis, designated as a methodological basis. Based on the concept of managerial roles of I. Adizes, the authors defined the functional qualities of competitive management of small and medium-sized enterprises, expressed through four functional indicators: production of results, administration of activities, proactive and creative development, and integration of internal and external environment. Under the theory of production factors of O.V. Inshakov, C. Hofer, the authors substantiated the content of eight resources of management of small and medium entrepreneurship: human, technical, material, organizational, information, institutional, financial, reputation. The article’s scientific novelty lies in combining the concept of managerial roles with the resource-factor approach and applying the cognitive approach to determine the degree of resource participation in ensuring the competitive functioning of small and medium-sized businesses.
The slow neutron-capture process in stars
Authors: Vescovi Diego
Published: June 2024

Most elements heavier than iron in the Universe are produced through neutron captures. The solar system abundance distribution indicates that they were created primarily in two nucleosynthetic processes, the slow and the rapid processes. Here, we cover the fundamental aspects of the s-process. The ever-growing amount of information gathered from astronomical observations and analyses of stardust grains recovered from meteorites provides tight constraints on the mechanisms of the s-process and where it occurs. Comparison of chemical abundance patterns with stellar model predictions clearly identifies evolved low-mass and massive stars as the s-process astrophysical sites.
Galactic chemical evolution with the short-lived isotopes 53Mn, 60Fe, 182Hf, and 244Pu
Authors: Wehmeyer B. , López A. Yagüe , Côté B. , Pető M.K. , Kobayashi C. , Lugaro M.
Published: June 2024

We run a three-dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn from supernovae of type Ia (SNIa), 60Fe from core-collapse supernovae (CCSNe), 182Hf from intermediate mass stars (IMSs), and 244Pu from neutron star mergers (NSMs) in the Galaxy. We compare the GCE of these short-lived radioactive isotopes (SLRs) to recent detections on the deep-sea floor. We find that although these SLRs originate from different sites, they often arrive conjointly on Earth.
Exploring Enhanced 12C Production in Astrophysical Environments through Inverse Maxwellian Averaged Reaction Rate
Authors: Baishya A. , Santra S. , Rout P.C. , Pal A. , Santhosh T.
Published: June 2024

A significant increase in stable 12C production can result from lightparticle- induced deexcitation from resonances above the 3α breakup threshold. The enhancement in 12C production has been calculated in the temperature range of T9 = 0.1 to 10 using the inverse Maxwellian Averaged Reaction Rate (MARR) generated directly by the TALYS code, a unique new approach. Calculated proton-induced enhancements are nearly identical to the conventional approach, but the neutron-induced enhancements are strikingly different at low temperatures. An attempt has been made to analyze the differences between the two approaches.
Shedding light on 17O(n,α)14C reaction at astrophysical energies with Trojan Horse Method and Asymptotic Normalization Coefficient
Authors: Oliva Alessandro Alberto , Guardo Giovanni Luca
Published: June 2024

The 17O(n,α)14C reaction plays a critical role in astrophysical nucleosynthesis, particularly influencing the s-process in stellar environments. Due to the limitations of direct measurement techniques, indirect methods such as the Trojan Horse Method (THM) and Asymptotic Normalization Coefficient (ANC) analysis are employed to study this reaction at astrophysical energies. This paper discusses the application of THM and ANC to derive the reaction cross sections and explore the contributions of various resonant states of 18O. The results obtained from these indirect methods are consistent and provide new insights into the reaction mechanisms, enhancing our understanding of neutron capture processes and neutron poisons in stars. The findings also demonstrate the effectiveness of combining THM and ANC for studying neutron-induced reactions, potentially facilitating future research using Radioactive Ion Beams (RIBs). This work underscores the importance of indirect measurement techniques in advancing nuclear astrophysics, particularly where direct measurements are challenging.

Published: June 2024

Introducción En los últimos años, la cirugía ha ganado relevancia en el tratamiento de las fracturas del extremo distal del radio (FEDR). Dentro de las técnicas quirúrgicas, la osteosíntesis con placa mínimamente invasiva (minimally-invasive plate osteosynthesis, MIPO, en inglés) está en auge, y se han incrementado sus indicaciones respecto a la técnica convencional.

Materiales y Métodos Estudio retrospectivo que incluyó 81 pacientes intervenidos de FEDR durante el año 2021 en nuestro centro hospitalario, correspondientes a fracturas de los tipos I, II y III de la clasificación de Fernández. Se compararon resultados radiológicos, clínicos y funcionales, y la aparición de complicaciones al finalizar el seguimiento a los 6 meses.

Resultados El grupo MIPO estuvo formado por 21 pacientes (8 hombres y 13 mujeres) con una edad media de 57,3 años, y el grupo convencional, por 60 pacientes (11 hombres y 49 mujeres) con una edad media de 60,8 años. La Escala Radiológica de Castaing mostró un resultado global favorable para la técnica MIPO frente a la técnica convencional (p = 0,049), y se obtuvieron diferencias a favor del grupo MIPO en la inclinación sagital/volar (10,5 vs. 7,3°; p = 0,0006). La Escala Visual Analógica (EVA) ofreció un resultado de 1,5 para la técnica MIPO, y de 2,9 para la técnica convencional (p = 0,0141). La puntuación en la versión corta del cuestionario de Discapacidades de Brazo, Hombro y Mano (Quick Disabilities of the Arm, Shoulder and Hand, QuickDASH, en inglés) fue ligeramente superior para el grupo MIPO (13,5%) respecto al grupo convencional (19,6%), pero no tuvo significación estadística. Se reportaron resultados similares para el rango de movimiento (RDM), excepto en la pronación y la fuerza de prensión, que fueron favorables para el grupo MIPO. Las complicaciones, como lesión nerviosa, dolor crónico, lesión tendinosa y secuelas estéticas, fueron mayores en porcentaje con la técnica convencional.

Conclusión Para el tratamiento de las FEDR, la técnica MIPO, empleando placa extracorta mediante un abordaje biológico, puede lograr resultados funcionales al menos tan buenos como los de la técnica convencional, con mejores resultados radiológicos, menor dolor posoperatorio, menor tasa de complicaciones y mejores resultados estéticos.

Published: June 2024

Este estudio descriptivo presenta una amplia experiencia clínica en el tratamiento de músculos aberrantes alrededor de la mano por medio de 23 casos clínicos con imágenes de enorme interés, dada la baja incidencia de estas afecciones. De todos ellos se registraron sus manifestaciones clínicas específicas. Los músculos supernumerarios que se hallaron fueron: extensor digitorum brevis manus (EDBM), extensor propio del dedo medio, músculos palmares aberrantes, flexor carpi radialis brevis (FCRB) y músculo abductor digiti minimi aberrante (ADMa).

El EDBM fue detectado en 7 casos, con una incidencia bilateral del 30%. En dos casos, se asociaba con un ganglión dorsal. La exéresis quirúrgica resultó en la resolución completa de los síntomas. El extensor propio del dedo medio, que es una presentación extremadamente rara, fue extirpado debido a molestias que se intensificaban con la actividad manual. Se observaron dos casos de músculos palmares supernumerarios, uno de los cuales resultó ser un lumbrical aberrante que requirió intervención quirúrgica por irritación nerviosa.

El FCRB se presentó en tres casos en varones con alta demanda laboral, detectados clínicamente por su notable volumen; la extirpación quirúrgica condujo a la desaparición de las molestias. Cinco casos de músculo palmar menor accesorio (palmaris longus profundus, PLP) se presentaron como incidentaloma en una cirugía de liberación del túnel carpiano. La extirpación del PLP, realizada durante la cirugía, resultó en una clara mejoría de la sintomatología. El ADMa, detectado en cinco casos, provocaba una compresión del nervio cubital. En los casos más graves, la cirugía combinada con la apertura del canal de Guyon condujo a una mejoría significativa.

Se trata de una de las mayores recopilaciones de músculos supernumerarios publicadas, y su revisión pone de manifiesto la necesidad de considerar los músculos supernumerarios en el diagnóstico diferencial de otros síndromes clínicos más frecuentes.

Authors: Shaji Mohamed , Bhandary Srikala , Abhilash Simna , Tanna Dhvani Abhijit
Published: June 2024

Primary teeth have considerably fewer anomalies than permanent teeth. Rarely does a primary canine have two roots. This kind of strange abnormality could cause issues with exfoliation or extraction. The significance of anomalies must be emphasized to make a proper diagnosis and ensure a successful course of therapy. As far as we are aware, Dakshina Kannada district has never previously reported a maxillary deciduous canine with two roots. The objective of this case study was to raise awareness of the potential morphological changes in deciduous canines and to emphasize the implications of precise diagnosis and radiographic imaging from various viewpoints. To allow a better treatment outcome and prevent unintended problems, clinicians should take into account all potential tooth abnormalities or anomalies, following a periodic intraoral and radiographic evaluations.

Delayed Wound Healing Resulting from Inflammatory Process in Craniectomy Patients Treated with BioGlue: A Case Series with Literature Review
Authors: Wongsirisuwan Methee
Published: June 2024

Background BioGlue is touted as a safe and effective sealant for various surgical procedures. This article describes five cases of delayed wound healing associated with the use of BioGlue after craniectomies.

Case Description Five patients of different genders and ages who had undergone craniectomy with BioGlue were presented to our medical center with wound dehiscence and purulent discharge. The first attempt to solve this problem by incision and drainage was unsuccessful. The removal of BioGlue is necessary to eliminate these problems.

Discussion The presence of wound dehiscence and aseptic cystic contents may indicate a chronic inflammatory process following the application of BioGlue. This problem usually occurs within a few months after wound closure. For rapid intervention, it is recommended to perform an incision and drainage and remove the BioGlue. The main risk factor is directly applying BioGlue to the skin, subcutaneous tissue, or titanium material.

Conclusion Neurosurgeons should exercise caution and be aware of a possible delayed chronic inflammatory process in surgical wounds associated with the use of BioGlue as a sealant, especially when the product is used without cranial coverage or in cases where it comes into direct contact with subcutaneous tissue or titanium material. To resolve this issue quickly, BioGlue should be completely removed at the first attempt at incision and drainage.
“We are a hub for tech, innovation, and entrepreneurship”: how places use tech-driven storytelling for nation branding
Authors: Mashiah Itzhak
Published: June 2024

Innovation is essential for all entities today, including cities, states, regions, and nations. These entities not only establish policies to drive actual innovation but also implement marketing strategies to maintain an image of innovation. This study highlights the strategic role of the innovation-messaging of places around the world. It explores the potential benefits of employing innovation-messaging at the national level for branding purposes, emphasizing its role in job creation, the utilization of inherent resources, as well as its ability to stimulate tourism and economic growth. Through content analysis comparing the ‘most innovative nations’ and ‘less innovative nations’ worldwide, this paper underscores the necessity of innovation-centered storytelling and high-tech marketing strategies in shaping the image of nations. The study also discusses innovation diplomacy and the soft power adopted by nations to promote such messaging for nation branding.
Horizontal subcontracting and the global factory
Authors: Buckley Peter J. , Murphree Michael , Anderson John
Published: June 2024

The focus of this article is the examination of the factors that trigger the addition of horizontal subcontracting to the structure of global factories. Horizontal subcontracting takes place when one firm is contracted to produce a given item, fills as much of the order as they are able to based on their available capacity, and subsequently subcontracts the remainder to a qualitatively identical firm. We find that similar entrepreneurial backgrounds of contract manufacturers lead to strong business ties in the same industry and stage of production; low-cost, used production machinery and inexpensive factory rent lead to low barriers to entry; tightening labor markets, limited capital access and lumpy or uncertain demand lead to the need to avoid underused internal capacity, and the widespread use of digital sourcing platforms by buyers enables contract manufacturers to receive orders both small and much larger than their internal production capacity. These factors combine to produce many networked small manufacturers who use horizontal subcontracting to ensure sustained demand. Currently a largely China-based phenomenon, horizontal subcontracting is likely to spread beyond China, offering a new source of vitality to low-cost manufacturing in global factories, keeping global factories viable into the future.
Perceptions are everything: individuals’ normative attitudes toward inequality and political participation in Europe
Authors: Loveless Matthew
Published: June 2024

The notion that national-level income inequality shapes individuals’ traditional political participation choices, based on differences in individuals’ income levels, is weakening. The inclusion of individuals’ perceptions of and attitudes toward inequality has undermined two essential assumptions of this relationship, namely that all individuals can both correctly assess national-level inequality and that they respond to inequality in accordance with their socio-economic group. Using the European Values Surveys (1990–2017) in more than 40 countries, we examine inequality perceptions and political participation, including non-traditional political participation. We find that when individuals’ normative inequality attitudes are introduced, (1) the interactions between individuals’ income levels and changes in national-level income inequality nearly universally disappear. And more importantly, (2) normative attitudes have significant and consistent effects on political participation choices such that negative orientations toward inequality attenuate traditional forms of political participation and motivate a number of non-traditional forms.
Bifurcation and onset of chaos in an eco-epidemiological system with the influence of time delay
Authors: Pandey Soumik , Das Debashis , Ghosh Uttam , Chakraborty Sarbani
Published: June 2024

In the present article, we investigated a delay-based eco-epidemic prey–predator system in the presence of environmental fluctuations where predators engage with susceptible and infected prey, adopting Holling type II and ratio-dependent functional responses, respectively. During the study of the considered model, we identify each potential equilibrium point and its local stability criterion. The basic reproduction number has been computed, and the backward bifurcation about the disease-free equilibrium point was analyzed. The article illustrates Hopf bifurcation, global stability at the endemic equilibrium point, and their graphical depiction. We look over the variations in the dynamics of non-delay, delayed, and stochastic systems, revealing that a fixed level of temporal delay results in chaotic motion for the increasing strength of the saturation constant yet is potentially controlled by the predator growth rate. To study the dynamic behavior of the solution of the considered system and verify all theoretical results, we use numerical simulation and minutely analyze the influence of model parameters on the solution of the considered system. The stochastic transition is studied by varying the strength of stochastic fluctuation and the effect of delay.

Published: June 2024

Optical resonators are widely utilized to enhance light–matter interaction by focusing electromagnetic waves into deep sub-wavelength regions. Here, we first present a metallic bowtie split ring (BSR) optical resonator as an asymmetric light coupler for a terahertz (THz) graphene photothermoelectric (PTE) detector. The giant THz field enhancement in the slit region of BSR is mediated by two types of resonances: the inductor–capacitor (LC) and the dipole resonances, which greatly increase the THz absorption, resulting in the sensitivity improvement of the THz PTE detector. In detail, the LC and dipole resonant behaviors of BSR are systematically investigated in both theoretical and experimental aspects. Compared with the dipole resonance, the LC resonance leads to stronger electric field localization and enhancement. An optimized BSR is designed and integrated with a graphene THz PTE detector, and an ultrasensitive THz PTE response is demonstrated. At room temperature and in zero-bias mode, the key detection parameters—responsivity, sensitivity (noise-equivalent power), and speed—are 138 V/W, 25 pW/Hz1/2, and 3.7 µs, respectively. Our results indicate that the LC resonance supported by BSR can introduce strong local field enhancement, which is helpful for realizing high sensitivity THz detectors.
Creating and detecting observable QED plasmas through beam-driven cascade
Authors: Qu Kenan , Fisch Nathaniel J.
Published: June 2024

Quantum electrodynamic (QED) plasmas, describing the intricate interplay of strong-field QED and collective pair plasma effects, play pivotal roles in astrophysical settings like those near black holes or magnetars. However, the creation of observable QED plasmas in laboratory conditions was thought to require ultra-intense lasers beyond the capabilities of existing technologies, hindering experimental verification of QED plasma theories. This paper provides a comprehensive review of recent studies outlining a viable approach to create and detect observable QED plasmas by combining existing electron beam facilities with state-of-the-art lasers. The collision between a high-density 30 GeV electron beam and a 3 PW laser initiates a QED cascade, resulting in a pair plasma with increasing density and decreasing energy. These conditions contribute to a higher plasma frequency, enabling the observation of ∼0.2% laser frequency upshift. This solution of the joint production-observation problem should facilitate the near-term construction of ultra-intense laser facilities both to access and to observe the realm of strong-field QED plasmas.
Angle of attack impact on flow characteristics around finite-length rotating columns
Authors: Lin Jianfeng , Wang Shizhao , Yao Hua-Dong , Su Yumin
Published: June 2024

The finite-length rotating column has been extensively studied because of its importance in various fields, such as marine and aerospace. In this study, the hydrodynamic performance of a finite-length rotating column with two free ends at different angles of attack is investigated using a large eddy simulation method. The effects of various geometries (including an equal-section cylinder and a variable-section truncated cone), incoming flow velocities, column rotation speeds, and angles of attack on the lift and drag characteristics and wake field of the rotating column are analyzed. The results reveal that a free end creates a concentrated tip vortex, which shortens the effective length that can generate the Magnus effect. Across different geometries and computational conditions, a relatively consistent lift coefficient is found for angles of attack from 60° to 120°, with the cone design significantly reducing the drag by approximately 10% for angles of attack from 120° to 150°. These findings provide valuable insights into the practical application of finite-length rotating columns. Specific recommendations for optimizing the design of these columns are suggested, including choosing appropriate geometries and considering the effects of incoming flow velocities and column rotation speeds.
Session 1. Oral Presentation for: New insights into the Kingia Sandstone facies distribution, and implications for hydrocarbon prospectivity, north Perth Basin, Western Australia
Authors: Sloan Aisling
Published: June 2024

Presented on Tuesday 21 May: Session 1 The Kingia Sandstone has proven to be a prolific play fairway within the north Perth Basin, with primary porosity preservation observed down to at least 4600 mSS. However, the distribution of the Early Permian depositional and diagenetic facies has remained enigmatic. This is especially true given recent exploration results. Recent wells targeting the Kingia Sandstone have highlighted facies variability. As such, an opportunity exists to leverage legacy well data to investigate the interplay between sediment supply and accommodation space, resulting in improved reservoir characterisation. Through the integration of well logs, core and petrography studies, new insights into the spatial and temporal trends governing the presence and effectiveness of the Kingia are proposed. Implications of this work include Kingia Sandstone facies models that may be extended beyond known well control to help reduce subsurface uncertainty.

Session 10. Oral Presentation for: Post-stack 3D merging to fast-track regional interpretation – offshore Otway Basin case study
Authors: Gunning Merrie-Ellen
Published: June 2024

Presented on Wednesday 22 May: Session 10 Ideally when combining legacy 3D seismic surveys, differences in acquisition parameters warrant full pre-stack reprocessing from field data. However, there are occasions where this is not possible due to time, financial or data access constraints; a valuable alternative is post-stack merging and enhancement of existing migrations. This case was to produce a regularised and seamless 3D dataset of the highest possible quality, for the offshore Otway Basin, within 2 months. The input migrated volumes varied by data extent, migration methodology, angle range and grid orientation. Fourteen input volumes totalling 8092 km2 were post-stack merged and processed to produce a continuous and consistent volume, enabling more efficient and effective interpretation of the region. The surveys were regularised onto a common grid, optimised for structural trends, prior to survey matching. A mis-tie analysis algorithm, applied over a time window optimised for interpretation of key events, was used to derive corrections for timing, phase and amplitude, using a reference. This was followed by time-variant spectral and amplitude matching to improve continuity between volumes. Additional enhancements including noise removal and lateral amplitude scaling were also applied. The final merged volume offers significant uplift over the inputs, providing better imaging of structure and events and dramatically improving the efficiency and quality of interpretation. This enables rapid reconnaissance of the area by explorers. To access the Oral Presentation click the link on the right. To read the full paper click here
Session 10. Oral Presentation for: Insights into the depositional setting for the Gippsland Basin from modern basin-wide 3D datasets
Authors: Goody Angus
Published: June 2024

Presented on Wednesday 22 May: Session 10 The Gippsland Basin is a prolific hydrocarbon basin, with gas and oil initially discovered in the Barracouta (1965) and Kingfish (1967) fields. Historically the basin was covered with a patchwork of legacy 3D seismic surveys acquired from 1980 to mid-2000s, shot with old technology resulting in sub-optimal imaging of the subsurface. CGG reprocessed 10,190 km2 of legacy 3D data as part of their ReGeneration project in 2018 and in 2020 acquired 8751 km2 of long offset, deep tow and undershot seismic data. With these data sets, Woodside has been able to extract images of the regional depositional systems through the basin’s evolution. These observations range in scale from interpretation of individual channels and channel belts to the distribution of the major shoreface systems and marine fans.

Session 12. Oral Presentation for: Leading transformations – a holistic approach to leadership development
Authors: Marshall Scott A. , Freedman Eva
Published: June 2024

Presented on Wednesday 22 May: Session 12 So, what was Woodside’s challenge? How does an organisation lead through a business transformation, an industry transformation and a global energy transformation simultaneously? And what was Woodside’s answer? To redefine a whole of business approach to leadership and uplift leadership capabilities. The first step was to create a framework to revolutionise the concept of leadership and uplift leadership capability. Woodside wanted every employee to identify as a leader and lead, no matter what their role. In 2021, Woodside partnered and co-created a leadership development program with the Australian Graduate School of Management (AGSM) at UNSW. The program was designed for employees to uplift their leadership capability while empowering Woodsiders to be more deliberate in developing themselves and the organisation into the future. The commitment to date has seen thousands of employees undertake residential immersions and other learning experiences. Leadership and inclusive leadership capability have been uplifted and the framework has been leveraged as Woodside has successfully transformed operating models and completed a large merger. What was originally a stick drawing drafted on a napkin between two Woodside colleagues is now a conclusive framework known as Navigator. Since its inception in 2021 more than 2600 employees across all five countries have attended a Navigator immersion and more than 2500 Apply Learning experiences have been completed globally. Navigator has expanded its global reach across Woodside’s operations in Australia, China, the USA, Trinidad, and most recently in Dakar, Senegal.

Session 13. Oral Presentation for: Practical lessons from implementing a top-down, drone-based methane emissions quantification technology into global oil and gas operations
Authors: Turner David
Published: June 2024

Presented on Wednesday 22 May: Session 13 Reliable top-down quantification of methane emissions from oil and gas operations is increasingly crucial but challenging. Many new technologies are emerging that aim to offer solutions, but they vary widely in their actual field performance, cost, and breadth of applicability. Operators need to evaluate and test different technologies, which can be time-consuming and complex. Once a technology has been selected for use, then typically field trials follow before wider introduction to the operation. This process takes considerable time and effort, and frequently requires extensive learning by the teams involved. Additionally, interpretation of performance often depends upon measurement use-case (e.g. regulatory, voluntary, or leak detection and repair). This paper will share some of the learnings made by the users and technology provider in the assessment and global introduction of a high sensitivity drone-based methane emissions detection, localisation, and quantification technology. There will be a particular focus on practical, operational considerations for such introductions to help accelerate the ongoing efforts of others interested in implementing emissions quantification technologies. Examples from Australia and further afield (both onshore and offshore) will be used to illustrate key points within the paper which include the value of third-party technology validation, consistency across multiple operations and scalability/availability of services.

Session 14. Oral Presentation for: Implications of Western Australia’s updated domestic gas policy
Authors: Birda Krishan Pal
Published: June 2024

Presented on Wednesday 22 May: Session 14 In August 2023, Western Australia (WA) updated its domestic gas reservation policy to restrict onshore gas exports through the existing pipeline network, primarily affecting the Perth Basin. While the policy update aimed to secure domestic gas supplies amid projected shortfalls, it may complicate the outlook for the WA gas market through restricted access to capital, reduced incentives for substantial investments in large-scale developments, and the elimination of a potential future gas demand source for the state. WA’s domestic gas consumption is expected to peak by the end of this decade and then steadily decline as part of the state’s net-zero emission ambitions. In contrast, the liquefied natural gas (LNG) market especially in Australia’s main buying partners in Asia is set to grow into the 2040s, offering lenders demand certainty. This paper assesses the potential implications of WA’s updated domestic gas policy. The state’s domestic gas market is projected to require 8–10 tcf of gas over 2023–50. Currently producing and under-development fields are expected to supply approximately 5 tcf during this period, leaving around a 2 tcf gap to be filled by the onshore resource base and potential new Domestic Market Obligations (DMOs). The paper reiterates the importance of gas in WA’s energy transition and the need to ensure future supply failing which prices could rise to LNG netback or trigger further intervention.

Session 15. Oral Presentation for: 2023 Development and production review
Authors: Wilkes Martin
Published: June 2024

Presented on Wednesday 22 May: Session 15 Geopolitical uncertainty remained high in 2023 with Israeli actions in the Gaza strip, the continuing war in Ukraine and tension between China and several neighbouring countries. However, global inflationary pressures, surprisingly, eased during the year, and the prospect of a global recession faded from where it had been in 2022. In Australia continued activism around climate change issues, has impacted project developments and sentiment in the industry remained subdued. This paper looks back at the oil and gas production and development activities in Australia in 2023 providing historical context and trying to understand future implications for the industry. Liquefied natural gas (LNG) production in Australia remained close to record high levels although, not without problems. Both the Scarborough/Pluto 2 LNG project and the Barossa project continued to have legal and approval hurdles resulting in suspension of some execution activities. Elsewhere other projects continued with their plans, including the Kipper field in the Gippsland Basin, the Crux project in the Browse Basin and the Walyering project in the Perth Basin which was brought online in September 2023. The domestic markets also continued to have unique issues with major concerns about gas supply in the East, stalled developments and failing supply in the Northern Territory, and a renewed ban on any exports (including to other states) of gas from Western Australia.

Presented on Wednesday 22 May: Session 16 As a result of global aspirations to achieve energy transition along with the desire to ensure energy security, energy exporters proposed a series of new ‘carbon-neutral’ products – liquefied natural gas (LNG) and oil. In 2019, a new market was officially born after the first-in-history shipment of carbon-neutral LNG cargo from Shell to Japanese Tokyo Gas. Until 2021, it grew rapidly, however in 2022, announcements about volumes delivered to the customers significantly dropped. In this paper, we will explore the reasons for this dynamic, review perspectives of the carbon-neutral fuels markets, and explore the potential steps that producers and consumers could undertake to achieve global climate targets. We specifically focus on the consequences of implementing carbon capture and storage (CCS) technologies. Based on the data on the world CCS facilities, provided by the International Energy Agency, we conduct preliminary analysis of the capital costs associated with the construction of carbon capture, utilisation, and storage facilities. After that, we apply the cost estimation method (class 5) based on the US Department of Energy Classification, to estimate the costs of using CCS for emissions management in different regions/countries. As a result, the study demonstrates that due to the various economic, geographical and infrastructural limitations, it is more feasible to implement CCS on the producer’s side than on the consumer’s side. We also show what level of CCS implementation within the LNG value chain is economically feasible for different market participants and what the costs are.

Session 17. Oral Presentation for: Satellite based oil spill emergency response and recovery support
Authors: Pedersen Børre
Published: June 2024

Presented on Wednesday 22 May: Session 17 Oil spills at sea pose a complex and challenging problem. Detecting, reporting, and potentially acting on the spill are difficult tasks, especially if the information is only obtained from the perspective of a vessel. Near-real time and relevant information is crucial for effective management of an oil spill event. This paper demonstrates how satellite-based images, combined with methods for thickness extraction and oil drift trajectory, can provide end-users with actionable and timely information for emergency response and recovery support. The results show the high value of quick delivery and the importance of using multiple sensors and data sources during an emergency, which enhance situational awareness and decision making. We highlight the value of satellite imagery for oil detection and show how it can be used to document the polluter, identify relative oil thickness, model oil drift, and compare different sensors.

Session 18. Oral Presentation for: Probabilistic CO2 plume modelling
Authors: Tang David
Published: June 2024

Presented on Wednesday 22 May: Session 18 The Offshore Petroleum and Greenhouse Gas Storage Act 2006 provides the legal framework for carbon dioxide (CO2) storage projects in Australian Commonwealth waters, with the associated regulations and guidelines requiring that applicants for a ‘declaration of an identified storage formation’ consider ‘all migration pathways of which the probability of occurrence is greater than 10%’. The overseas Society of Petroleum Engineer’s CO2 Storage Resources Management System goes further and discusses the concept of modelling not only the subsurface CO2 plume itself but also the attendant pressure effects and displaced formation water, which, in that scheme, comprise part of a wider ‘containment area’. These collective requirements necessitate that the eligible carbon storage resources be assessed probabilistically, a requirement that can result in sizable static and dynamic models that are computationally heavy to simulate. This computational complexity places inherent, practical limitations on using ‘conventional’ probabilistic workflows, such as Monte Carlo simulation or Latin hypercube sampling. To address this limitation, factorial experimental designs were employed in the modelling workflow. Factorial designs are widely used in settings where individual experiments are costly or require prolonged periods and, when implemented correctly, can uncover underlying uncertainty distributions using a minimum number of simulation cases. The efficacy and power of this approach is demonstrated using CO2 injection and migration models for a carbon storage project located in offshore Western Australia, which is in the early development stage. The ability to test potential sensitivities rapidly has proven to be critical in refining and defining the project’s ultimate carbon capture and storage development plan.

Session 18. Oral Presentation for: Transforming offshore field developments with Pivotree™: an innovative technology solution for fast, cost effective, and low footprint projects
Authors: Merrick Christopher
Published: June 2024

Presented on Wednesday 22 May: Session 18 Pivotree™ represents a technology paradigm shift in offshore oil field development, reducing cost and providing a route to market for the operators of stranded resources. Conventional standalone projects, characterised by substantial upfront capital expenditures with complex equipment and high installation costs, are juxtaposed against the Pivotree™ solution, with a markedly reduced capital outlay that retains all the requisite safety and operational features associated with larger systems. A comparative study of activities, materials, and risks concomitant with different field development concepts are analysed for a range of reservoir characteristics, highlighting the financial advantages of the Pivotree™ technology using Multiple-Criteria Decision Analysis (MCDA). MCDA allows a systematic assessment and comparison of a broad spectrum of qualitative factors including safety, environmental impact, operability, maintainability, time to deploy, water depth, independence, and abandonment burden and development of a set of economic scenarios with the costs of different development concepts compared over the lifecycle phases from Drilling to Abandonment, and the Net Present Value (NPV) and Internal Rate of Return (IRR) calculated against a range of oil prices, and operating expenditures. A case study ‘Concept Select’ activity is performed using MCDA to evaluate the range of development options against the listed set of project and technology attributes. A set of weightings is provided for the purpose of analysis by the author equating to the corporate values and strategy of a fictional energy company. The MCDA analysis demonstrates that the Pivotree™ technology can unlock production from the global store of stranded offshore discovered resources.

Session 19. Oral Presentation for: Beetaloo gas, hydrogen and geothermal resources – insights from 3D basin modelling
Authors: Faiz Mohinudeen
Published: June 2024

Presented on Wednesday 22 May: Session 19 The Beetaloo Sub-basin hosts a large proven shale gas resource, and this study demonstrates the opportunities for other low-emission energy sources including geothermal energy and natural hydrogen. CSIRO has developed a 3D basin model that predicts reservoir rock properties, pore pressure, composition of hydrocarbons and gas capacity of the Velkerri and Kyalla shales. Kinetic modelling also demonstrates that where Velkerri shale is overmature for hydrocarbons it potentially generated significant amounts of free molecular hydrogen. However, the proportion of this hydrogen currently preserved in the basin is unknown. The model also reveals considerable temperature anomalies around specific structural domains with heat flow up to 100 mW/m−2, and these are likely associated with radiogenic basement lithologies. These thermal domains are targets to further investigate geothermal and natural hydrogen resource potential in the Beetaloo Sub-basin. To access the Oral Presentation click the link on the right.
