Journal of Resource Management and Decision Engineering In Press 2027 09 01 The Role of Blockchain Technology in the Supply Chain Performance of the Oil and Gas Industry The Role of Blockchain Technology in the Supply Chain Performance of the Oil and Gas Industry 1 11 EN Journal Article 2026 02 01 <p>When examining the potential of blockchain technology in the oil and gas industry, one of its most significant application areas is supply chain management. In terms of purpose, this study is applied research, and in terms of methodology, it adopts a causal-correlational approach using a questionnaire as the data collection instrument. A total of 254 questionnaires were distributed through simple random sampling among senior experts and information technology specialists in 2025. Reliability was assessed using Cronbach’s alpha, while face validity was evaluated through pilot testing. Content validity was calculated and confirmed using the Content Validity Index (CVI) and Content Validity Ratio (CVR). To determine the relationships between the independent and dependent variables within the conceptual research model, Structural Equation Modeling (SEM) and the AMOS software package were employed. The findings indicate that blockchain technology, particularly in the oil and gas industry, can facilitate process integration through decentralization and participatory decision-making, foster trust, and enhance transparency. Nevertheless, many large oil and gas companies continue to perceive investment in this technology as risky and have largely limited their actions to monitoring and evaluating the experiences and outcomes of leading organizations in this field.</p> <p> </p> https://journalrmde.com/index.php/jrmde/article/download/362/312
