Oil Well Blowout

Definition - What does Oil Well Blowout mean?

An Oil Well Blowout is a situation whereby crude oil or natural gas flows uncontrollably from an oil reservoir. This condition occurs when the oil well control techniques are not able to control the pressure of the surge from the well. It is commonly referred to as a blowout, wild well, gusher or an oil gusher. When a wild well is not controlled or the blowout control techniques fail, then the situation can lead to a disastrous fire due to the leakage of oil or gas from the high-pressure reservoir.

Petropedia explains Oil Well Blowout

In early days of oil exploration, the drilling of an oil well would often lead to an Oil Well Blowout due to lack of techniques that could control the high-pressure reservoir. Also known as a wild well or gusher, this is a situation in which oil or gas flows with high pressure from the wellbore after the well is drilled. This well is extremely hazardous and it leads to wastage of the reservoir contents. It is explosive in nature and it can cause a wild fire that poses risk to the workforce and the drilling equipment. The outburst can also cover the surrounding land with tons of oil and affect the environment. As a preventive method, blowout preventers and other blowout control methodologies are used to ensure that the well pressure is stable.
