The Metaverse refers to the integration of physical and virtual realities, offering new possibilities for enhancing operations and services across various industries. However, its application in the energy sector is still in its nascent stage. The energy industry, crucial for the global economy and society, faces significant challenges due to its complex and risky nature, such as health, safety, and environmental (HSE) concerns, and the remote locations of extraction sites. Although some studies have explored the use of the Metaverse in this industry for data visualization, energy process modeling, and training, a comprehensive review of existing technologies and applications is lacking. This article addresses this gap by examining the potential of the Metaverse for the energy industry, using the Oil&Gas sector as a case study. We identify the essential technologies needed to create a realistic and immersive Metaverse experience and review the current literature on its industrial applications in the energy sector. Distinguishing our work from others, we present four practical case studies developed from our own experience in the Oil&Gas sector. These cases demonstrate the tangible benefits of Metaverse solutions in improving operational efficiency, reducing costs, and enhancing worker safety and productivity, highlighting the unique value of the Metaverse in addressing industry-specific challenges.
