This paper constructs a modified hypothesis extraction method (MHEM)–structural decomposition analysis (SDA)–structural path decomposition (SPD) analytical framework and employs the 2018–2022 Chinese input–output tables to discuss sectoral consumption correlations, driving forces of consumption, and the transmission paths of carbon energy (CE), oil and gas energy (OGE) and electric energy (EE). The results of the study indicate that energy-exporting sectors are primarily energy production or conversion industries, while energy-importing sectors are mainly in the construction sector. China’s energy consumption has shown consistent year-on-year growth, with the primary driving force being the intensity of energy consumption and the secondary factor being per capita demand. The consumption of all three types of energy is primarily directed toward domestic consumption and capital formation. Regarding energy consumption transmission paths, the first-order path with the largest overall impact on CE is “electricity, gas, and water supply sector → domestic consumption”, while higher-order paths are primarily subpaths of “electricity, gas, and water supply sector → capital formation”. For OGE, the main supply and transfer path is “coke, refined petroleum, and nuclear fuel sector → domestic consumption”, along with its subpaths. In contrast, EE transmission is more balanced, with a high demand for electricity across all sectors. Full article

The objective of this study was to evaluate the catalytic performance of commercial Nb₂O₅, supplied by CBMM, in the production of biodiesel by transesterification and esterification, using different feedstocks (soybean, corn, sunflower, and waste oils) and both methyl and ethyl routes. For this, the catalyst was characterized in terms of its crystal structure by X-ray diffraction (XRD), specific surface area using the Brunauer–Emmett–Teller (BET) technique, thermal stability by thermogravimetric analysis (TGA), morphology by scanning electron microscopy (SEM), acidity by ammonia desorption at programmed temperature (TPD-NH₃), and catalytic activity by gas chromatography. The results from the structural analyses indicated that Nb₂O₅ has a single monoclinic phase and a morphology consisting of irregular agglomerates. The specific surface area was 1.3 m²/g, and its density was 4.639 g/cm³. The thermogravimetric analysis showed that the material has thermal stability, maintaining its structural integrity up to temperatures as high as 1000 °C. The total acidity reached 301 μmol NH₃/g, indicating the presence of Brønsted and Lewis acidic sites. In catalytic tests, Nb₂O₅ showed higher efficiency in the methyl route, achieving an initial conversion of 96.43% in esters with soybean oil, outperforming other feedstocks. However, catalyst reuse over five cycles revealed a progressive decrease in catalytic activity, possibly due to blocking active sites by adsorbed products, as confirmed by FTIR and XRD analyses conducted on the catalyst. Despite decreased activity after the cycles, the catalyst maintained its crystal structure, indicating structural stability. These results demonstrate the potential of Nb₂O₅ as a heterogeneous catalyst for biodiesel production, particularly with the methyl route and high-quality oils. This study highlights the relevance of Nb₂O₅ in biodiesel synthesis, contributing to sustainable practices and technological advancement in the renewable energy sector. Full article

The oil and gas (O&G) sector depends on information analysis, making digital transformation vital. Industry-specific factors like environmental, regulatory, operational, and security challenges shape its tech adoption. This paper identifies and examines the barriers and drivers of digital transformation in O&G through a literature review and expert insights, leading to a questionnaire assessment. Interpretive Structural Modeling (ISM) was employed to create a structural model that illustrates the interactions between these barriers, helping experts understand how to achieve digitization within the industry. The questionnaire analysis identified the key barriers based on their RII values: “Experiments requiring significant time for validation of new technologies”, “Technical complexities of new technologies”, “Security concerns”, “Insufficient strategies”, and “Organizational culture and resistance to change”. The ISM indicated that the “Technical complexities of new technologies” and the “Lack of readily deployable technologies” are the most influential barriers. Addressing these is crucial for O&G companies to unlock digitalization potential. Full article

Encouraging oil and gas (O&G) companies to develop renewable energy sources (RESs) is crucial for China’s energy strategy and sustainable development. The transition from O&G energy to RESs is a complex and systemic process that requires a comprehensive analysis of both internal and external driving factors. This study integrates the theoretical dimensions of energy transition with the operational realities, utilizing structural equation modeling (SEM) to analyze these factors and their influence on the decision-making process for companies in this sector. A multi-group analysis was conducted to explore differences in motivational mechanisms among groups with varying levels of transition willingness. The findings reveal that environmental awareness, economic value estimation, knowledge accumulation, dynamic capabilities, structural overlap, and government actions significantly promote the energy transition, whereas resource endowment acts as a barrier. Moreover, the willingness to transform moderates the effects of government actions and pressures from other stakeholders on corporate environmental awareness and the transition to RESs. This article provides more comprehensive research perspectives on exploring the driving mechanisms behind the transition to renewable energy, emphasizing the importance of governments playing diverse roles based on the specific internal conditions and highlighting the long-term impact of other stakeholders on sustainable development.

Sustainable supply chain management (SSCM) has become a hot topic on which eminent researchers are working on a daily basis. A lack of clarity in the fundamental differences between SSCM and green supply chain management (GSCM) is being observed in this field of research. However, it is regrettable to note that there is a huge deficit of research in the oil and gas (OG) industry, mainly in developing countries (DCs), where this sector of activity is the most lucrative and polluting. The purpose of this research is to present the practices of SSCM in the framework of the quadruple helix approach in the oil and gas industry in specific geographical areas of developing countries by conducting a systematic literature review (SLR) of papers published from 2012 to 2024 focused on both the OG industry and DCs. As part of this study’s findings, the authors highlight the distinction between SSCM and GSCM by building a conceptual framework that applies the triple bottom line of SSCM to the OG industry and demonstrates that GSCM, which is more related to environmental issues, is a part of SSCM. Therefore, in order to be more efficient and to have a great impact on their performances, OG companies in DCs should apply SSCM practices, which are close to circular business rather than GSCM practices, especially because their implementation can be influenced by certain barriers and pressures that involve the use of the QHC.

Sustainability reporting within the oil and gas (O&G) industry started back in the 1990s and has improved longitudinally since then. However, when reporting their sustainability-related practices and initiatives, O&G companies seldomly mention the term green supply chain management (GSCM). The study aims to investigate the development of GSCM practices in the O&G sector and to categorize how they are integrated with the sustainability practices reported by the industry. A multi-phase research approach was adopted consisting of a comprehensive literature review, followed by a single case study employed in an international oil and gas company. Primary data were collected by conducting 12 semi-structured interviews with senior members of an O&G company. Thematic analysis was employed to analyze the primary data from the interviews and to synthesize this work with the secondary data in order to answer the research question. The research identifies that the adoption of green purchasing practices is still in its infancy, whereas green production practices are more advanced compared to the current academic literature on the O&G industry. Additionally, new insights are obtained on how O&G companies are diversifying their business models and investing in the renewable energy business. The results of this work will enable O&G businesses to understand the latest developments in GSCM practices and how they are impacting the O&G sector. Practitioners will also be able to benchmark their current GSCM practices with the research findings and develop and formulate strategies to maximize the implementation of GSCM practices.

This study conceptualises the extent of supply chain collaboration in the oil and gas (O&G) sector using the evidence from the literature and the primary data collected from supply chain practitioners across various companies in the UK O&G sector. The goal is to establish how the sector can address its traditional narrow and adversary relationships that undermine the sector’s ability to be resilient and competitive considering the volatility of global oil prices and the trilemma (i.e., energy transition, energy security, and energy diversification) of issues facing the sector. Using exploratory quantitative online surveys, data were collected from 82 supply chain practitioners across Tier 1, 2, and 3 companies in the UK O&G sector. The collected data were analysed thematically, providing deeper insights into supply chain collaboration, including its motivations and barriers in the UK O&G sector. The findings show that the pattern of collaboration in the O&G sector is transient, situational, and mostly influenced by the sector’s performance and global economic situations. The findings further show that the nature of the relationship in the O&G sector is mostly dependent on how it contributes to the performance of each business rather than the supply chain. This study argues that businesses in the oil and gas sector need to re-examine their relationships to enhance their competitiveness. It proposes that the sector should embrace strategic collaborations as the sector faces many disruptions, particularly from energy transition and the decommissioning of assets. Full article

This paper addresses the global imperative of tackling environmental challenges, particularly in the context of the carbon-intensive oil and gas (O&G) industry, which is one of the heaviest carbon-emitting industries. Competitive advantages in this industry often stem from external connections rather than internal capabilities. How companies assess their business partners, including electric vendors, from an environmental standpoint, using a combination of quantitative and qualitative approaches, was explored using a systematic literature review approach. This literature review delves into the realm of green supply chain management, covering topics, such as carbon cap and trade, carbon offsets, renewable energy, regulations, finance, and vendor selection. Key findings from this review highlighted the limited number and lack of depth of studies regarding the presence and impact of electrical vendors, who play a crucial role in the oil and gas sector. Furthermore, our review identified a general lack of research on green supply chain management metrics, particularly in the context of the oil and gas industry and the roles and technical contributions of electric vendors.

The oil and gas (O&G) field is the most sought-after industry in the Gulf Cooperation Countries (GCCs) and holds significant importance in the region’s economy. Therefore, this sector requires various industrial electrical, and electronics equipment (EEE) products to perform multiple tasks throughout the upstream, downstream, and midstream segments. However, as these EEE products approach their end of life (EoL), the sector faces the challenge of managing failed units. As a result, replacing or recycling failed EEE products can contribute to the growing problem of electronic waste (e-waste), which can have severe environmental consequences. In addition, while some EEE products can be repaired or remanufactured with low reliability, many others cannot be fixed due to various technical reasons. This paper’s primary goal is to propose a circular economy strategy and sustainable practices that promote the longevity of industrial EoL electronic products in the O&G sector through remanufacturing. We introduced and implemented a new mathematical score, the Index Of Repairability (IOR), which aims to assess the ease of EEE repairability in the O&G sector and improve their lifespan and durability based on four criteria: design, spare parts availability, software access, and documentation. This novel mathematical metric leverages the analytic hierarchy process (AHP) and set theory. Additionally, original equipment manufacturers (OEMs) can adopt and benefit from this innovative IOR by incorporating eco-design principles and designing more easily repairable industrial products for technicians, thereby reducing the negative impact of e-waste, enhancing stakeholder satisfaction, and minimizing downtime. Furthermore, governmental organizations can implement regulations and incentives to advocate for and mandate the use of the IOR by OEMs, ensuring that the electronics industry prioritizes repairability, remanufacturing, and sustainability.

To fill a gap in understanding of the Generative Voluntary Safety Reporting Culture (GVSRC) in the Gulf of Mexico (GOM) Oil and Gas (O&G) sector, perspectives of stakeholders based on their experiences were explored using attributes of a proposed Offshore Safety Action Program (OSAP) modeled after the Aviation Safety Action Program (ASAP). A phenomenological approach encompassing semi-structured interviews (n = 18) and five focus-group sessions (n = 18) was used to collect data from a cross-section of top management, supervisors, regulatory representatives, and subject-matter experts (SME). Four themes emerged from a Thematic Analysis: (1) Voluntary safety reporting culture, (2) Voluntary safety reporting bottlenecks, (3) Universality, and (4) Organizational review of safety events. Most respondents strongly supported the OSAP because it ensures a formalized adjudication of voluntary safety reports by an Event Review Committee (ERC) with representation from employees, management, and regulators. Most respondents supported the non-punitive and confidential attributes of the OSAP as a means to enhance GVSRC. However, there were varying perspectives on defining intentional disregard for safety under the OSAP. Due to the enumerated challenges of cost, respondents agreed that organizations use a scalable process commensurate with the complexity of their operations when adopting the OSAP. A veritable framework for data-driven corrective actions, organizational learning, and enhanced GVSRC in the offshore sector is a potential policy implication of adopting the OSAP. Full article

The oil and gas (O&G) sector is a critical energy infrastructure to a Nation’s welfare. As developed as the O&G industry may seem, its aging infrastructure gradually shows numerous challenges to keep up with the growing energy demand, increasing operation costs, and environmental concerns. A robust O&G infrastructure that is risk-free, reliable, and resilient towards expected or unexpected threats can offer an uninterrupted supply of O&G to downstream stakeholders, competitive prices to customers, and better environmental footprints. With the shift towards renewable energy, the notion of sustainable development should be firmly embedded in O&G infrastructure and operations to facilitate the smooth transition towards future renewable energy generation. This paper offers a comprehensive and innovative approach to achieving sustainable development for O&G infrastructure by examining it from a holistic risk, reliability, and resilience (3Rs) perspective. The role of each individual concept and their collective influence on sustainable development in the O&G industry will be thoroughly discussed. Moreover, this paper will highlight the significant impact of the holistic 3Rs approach on sustainable development and propose future research directions. Given the complexity of O&G infrastructure, it is crucial to incorporate sustainable development practices into every dimension of the O&G infrastructure, iteratively and continuously, to achieve the ultimate goal of long-term sustainability. This paper makes a significant contribution to the field by providing valuable insights and recommendations for achieving sustainable development in the O&G industry. Full article

With the growing pressure to substitute fossil fuel-based generation, Renewable Energy Sources (RES) have become one of the main solutions from the power sector in the fight against climate change. Offshore wind farms, for example, are an interesting alternative to increase renewable power production, but they represent a challenge when being interconnected to the grid, since new installations are being pushed further off the coast due to noise and visual pollution restrictions. In this context, Multi-Terminal High Voltage Direct Current (MT-HVDC) networks are the most preferred technology for this purpose and for onshore grid reinforcements. They also enable the delivery of power from the shore to offshore Oil and Gas (O&G) production platforms, which can help lower the emissions in the transition away from fossil fuels. In this work, we review relevant aspects of the operation and control of MT-HVDC networks for wind power integration. The review approaches topics such as the main characteristics of MT-HVDC projects under discussion/commissioned around the world, rising challenges in the control and the operation of MT-HVDC networks and the modeling and the control of the Modular Multilevel Converter (MMC) stations. To illustrate the challenges on designing the control system of a MT-HVDC network and to corroborate the technical discussions, a simulation of a three-terminal MT-HVDC network integrating wind power generation and offshore O&G production units to the onshore grid is performed in Matlab’s Simscape Electrical toolbox. The results highlight the main differences between two alternatives to design the control system for an MT-HVDC network. Full article

Nowadays, the Oil and Gas (O&G) industry faces significant challenges due to the relentless pressure for rationalization of project expenditure and cost reduction, the demand for greener and renewable energy solutions and the recent outbreak of the pandemic and geopolitical crises. Despite these barriers, the O&G industry still remains a key sector in the growth of world economy, requiring huge capital investments on critical megaprojects. On the other hand, the O&G projects, traditionally, experience cost overruns and delays with damaging consequences to both industry stakeholders and policy-makers. Regarding this, there is an urgent necessity for the adoption of innovative project management methods and tools facilitating the timely delivery of projects with high quality standards complying with budgetary restrictions. Certainly, the success of a project is intrinsically associated with the ability of the decision-makers to estimate, in a compelling way, the monetary resources required throughout the project’s life cycle, an activity that involves various sources of uncertainty. In this study, we focus on the critical management task of evaluating project cost performance through the development of a framework aiming at handling the inherent uncertainty of the estimation process based on well-established data-driven concepts, tools and performance metrics. The proposed framework is demonstrated through a benchmark experiment on a publicly available dataset containing information related to the construction cost of natural gas pipeline projects. The findings derived from the benchmark study showed that the applied algorithm and the adoption of a different feature scaling mechanism presented an interaction effect on the distribution of loss functions, when used as point and interval estimators of the actual cost. Regarding the evaluation of point estimators, Support Vector Regression with different feature scaling mechanisms achieved superior performances in terms of both accuracy and bias, whereas both K-Nearest Neighbors and Classification and Regression Trees variants indicated noteworthy prediction capabilities for producing narrow interval estimates that contain the actual cost value. Finally, the evaluation of the agreement between the performance rankings for the set of candidate models, when used as point and interval estimators revealed a moderate agreement ($a=0.425$).

Listening to employees’ concerns reduces their dissatisfaction, but moreover, for an organization to achieve sustainable success, employees must raise their creative voice and give their input in decision-making without the fear of rejection in a psychologically safe environment. Ethical leaders facilitate such a participative style of management. A bureaucratic culture, as is generally encountered in Pakistan’s work settings, poses real challenges to those who dare to speak up, therefore the importance of ethical leadership, leader–member exchange (LMX), and psychological safety cannot be neglected as coping mechanisms to sustain the employee voice for mutual gains. To investigate ethical leadership’s mediating mechanisms and boundary conditions on voice behavior, we examined a moderated mediation model with the leader–member exchange as a moderator and psychological safety as a mediator. Grounded in social exchange theory (SET), the current study uniquely posits and tests that employees feel psychologically safe in the presence of an ethical leader with whom they have high-quality social exchanges. Data were collected from 281 employees from the public corporations and private enterprises of the petroleum sector of Karachi. Results of the analysis, through SPSS and AMOS, revealed that psychological safety mediated the relationship of ethical leadership and voice behavior, while the indirect effect of ethical leadership on voice behavior (via psychological safety) is stronger for those employees who enjoy high-quality exchanges with ethical leaders. LMX was also found to moderate the relationship between ethical leadership and voice behavior. Contributions, recommendations, and limitations of the current study and further research areas are also discussed. The study offers practical insight on the mechanism of ethical leadership on employee voice behavior and recommends leaders to develop social exchanges to improve voice behavior for sustainable success.
