A sudden high-pressure gas flow from the wellhead after completion is a critical warning sign. This usually indicates gas migration, a tubing or packer leak, or sustained casing pressure, all of which pose major safety risks.

Why it’s dangerous:
-Gas can rapidly escalate to an uncontrolled release or blowout.
-High pressure threatens wellhead integrity and increases ignition risk.

Environmental impact:
Uncontrolled gas releases emit methane and VOCs, harming air quality and contributing to climate pollution. Even emergency flaring increases CO₂ and soot emissions.

What to do:
Secure the area, monitor all pressures, bleed off gas in a controlled manner, and perform well-integrity diagnostics. Fast response protects personnel, assets, and the environment.
