What is a relief?

When he experiences outbreaks well, which is sudden and uncontrolled extraction of natural gas or oil, the relief wells are one way to regain control. The relief is usually drilled, so that it intersects with blowing, either to reduce pressure or blocking the tank. If the aim is to alleviate pressure, the new relief may be attached to the original pipe. Otherwise, heavy drilling mud, cement or other materials can be pumped into the tank through a new well. These materials can basically stop the original well and effectively bring it back under control. When this happened, oil or gas would throw itself out of the ground. This is where the concept of Gusher comes, and the iconic picture of Derrick with a cloud of oil spray from the top is still connected to industry. These gushers were unnecessary and harmful to the intentional environment, so technology, such as Prevent (BOP), has been developed to prevent such situations. When these warranty fail, an outbreak may occur and the environment may be releasedgas or oil.

The

relief holes are one of the primary defense means against the outbreak if BOP and other warranties have failed. In some cases, the relief may be well drilled from any problems, although this practice is usually not ordered. Most embossed holes are drilled in response to a catastrophic explosion and must be perfectly focused to join the original well. If the goal is off at all, another relief must usually be drilled.

reliefs can be focused either on an underground grateful pipe or on a tank. If the embossed opening is focused on the tank, it is sometimes used to divert a certain pressure from the damaged original well. In other Cases, water, mud drilling, cement and other materials can be pumped to stop the outbreak. The exact method that is used may vary from one situation to another.

Relief Wells can also be used to stabilize the ground, which has nothing withpole with oil or gas. Unlike the holes for lightening oil and gas, they are usually drilled as preventive measures. When the country is saturated with water, wells can be used to pull some of them. This may have a stabilization effect that is sometimes used to prevent dam failure.
