abstract="Once it is established that an underground blowout is in progress, conventional well control alone will not suffice. There are several remedial control procedures that can be implemented. These include techniques for killing the well and techniques for plugging the thief zone. To increase the chances of these procedures working, the location of the thief zone should be known. There are several zone detection methods that are available for this purpose. Each underground blowout is a unique situation that must be studied and the action best suited for that situation must be undertaken.<p />",
