In this first episode of a four-part special podcast series with Siemens, Chiranjib Sengupta sat down with John Nixon, Vice President for Global Strategy in Energy, Chemicals, and Infrastructure, and Mike Houghton, Global Head of Sales at Siemens Digital Industries Software, to discuss how incorporating digital twins into oil and gas operations can unlock unique efficiencies and also make the industry more sustainable. As the global energy infrastructure landscape faces up to the realities of ageing assets, decarbonisation and the urgent need for digitalisation, leaders across energy, chemicals, and urban systems are confronting a main challenge: how to make infrastructure more intelligent, adaptive, and resilient. John and Mike discuss how the fusion of digital twins, artificial intelligence, and industrial software is changing the way energy infrastructure is designed, operated, and optimised. They explore how digital twins are evolving into living models that replicate real-time conditions, enabling predictive maintenance, risk mitigation, and system-wide efficiency at unprecedented levels. They also highlight how at Siemens, these capabilities are no longer experimental, but an essential part of their portfolio as industrial operators seek to future-proof assets against climate disruption, resource constraints, and operational efficiency.
