Offshore Well Location & Intercept P&A

Gulf of Mexico  ·  2025 – ongoing

Locating and plugging a cluster of buried offshore wells, among the longest-running releases on record

The challenge
  • A hurricane-driven seafloor mudslide toppled an offshore platform, burying a cluster of ~28 wells under sediment in ~475 ft of water.
  • Chronic release ongoing for years; well positions uncertain with no surface access.
  • Wells must be located and intercepted entirely subsurface, where usable surveys don't exist.
Our solution

Magnetic-ranging-led location and intercept: AMR + PMR while-drilling to deterministically locate each buried wellbore, then drill intercept / relief wells to permanently plug and abandon the cluster.

Early engineering underway, execution targeted end-Q4 2026 / Q1 2027
The result
~28 wells
to locate, intercept & permanently P&A
  • ·Deterministic subsurface well location via magnetic ranging (AMR + PMR)
  • ·Phased intercept / relief-well plan for permanent abandonment
  • ·Status: early engineering; execution targeted end-Q4 2026 / Q1 2027
