Extinguishing oil and gas gushers usually includes the following operations: removal of burnt-out equipment from the wellhead, extinguishing fire, setting isolation valves on the wellhead and killing of the well.

Depending on technical conditions of the gushing hole and the power of the gusher the following methods can be used to extinguish the open gusher:

• draining out gas to specially drilled inclined holes;
• intensive extraction of gas from the bottomhole zone of the blowing well through specially drilled inclined holes;
• waterflooding of gas zones;
• pumping kill fluids to the designed point of the well bore;
• making an isolation bridge (artificial packer) in the well bore;
• caving the hole with underground explosions;
• sealing the wellhead and its further squeezing with kill fluids.

Sealing the wellhead and squeezing it with kill fluids is the most frequently used method in the fields of the Far North. In order to seal the wellhead isolation valves are set on the burning wellhead of gushing well with the help of pulling constructions, i.e. not extinguishing the fire on the wellhead. In order to prevent inflammation and damage to the isolation valves the wellhead is sprayed through fire monitors.
