Case in point 

Closing the loop on a decades-old offshore liability

When a bankrupt predecessor left nine orphaned Gulf of America wells with no documentation, no safe access, and active methane leaks, Promethean Energy stepped in to eliminate the liability safely, thoroughly, and at the contracted budget.

  • Technology-led planning using UHD drones and LiDAR
  • Full platform rehabilitation before crew boards
  • First-ever offshore visual intelligence pilot for real-time safety monitoring
  • All nine wells plugged and abandoned, zero lost-time incidents or spills

Leading the conversation around responsible stewardship

Since 2023, Promethean Energy has sponsored Decommissioning and Abandonment Gulf of America, the industry’s leading forum for reducing the risk and cost of late-to-end-of-life asset management. This year, COO Martyn Fear discussed how our experience, business model, and operating practices — including supply chain management, solution development and risk management, and execution under intensive oversight — help us set a new benchmark for project excellence. 

The presentation culminated with a 2025 case study in which we leveraged our expertise and operating practices to stabilize a leaking, three-pile platform and manage the asset through permanent plugging.
