Summary
Investigation of a condensate and gas release from Well C-9 beneath a platform toppled by Hurricane Ike. The report examines a broken master valve, uncertain subsurface barrier failures and a proposed trapped hydraulic-pressure mechanism. It describes limited condensate recovery, valve replacement and cement squeezing to secure the well.
