Abstract
A well-head pipe of a leaking oil well is sealed by radial application of a high-energy magnetic pulse to the well-head pipe to thereby plastically deform the metal of the pipe casing and form the metal into a seal that caps the well-head pipe without cracking the pipe. A system for sealing an oil-well-head pipe having a metal casing includes an electromagnet dimensioned for placement around an exposed portion of the well-head pipe, with the electromagnet being disposed to radially apply a magnetic field to the pipe when the electromagnet is placed around the exposed portion of the pipe; and a capacitor bank and a transmission line for providing a high-energy current pulse to the electromagnet to cause the electromagnet to radially apply a high-energy magnetic pulse to the pipe to plastically deform the metal of the pipe casing and form the metal into a seal that caps the well-head pipe.
