Summary
An offshore drilling alert describes uncontrolled well gas flow after a safety-valve grease fitting failed during well-killing operations. A combustible atmosphere prompted evacuation; the well bridged two days later without injuries, fire or pollution. The operator replaced valve grease fittings with solid plugs and pressure-tested the valves.
