Title: Well sealing via thermite reactions

Patent · Tue Nov 15 00:00:00 EST 2016

OSTI ID:1332269

Lowry, William Edward; Dunn, Sandra Dalvit

A platform is formed in a well below a target plug zone by lowering a thermite reaction charge into the well and igniting it, whereby the products of the reaction are allowed to cool and expand to form a platform or support in the well. A main thermite reaction charge is placed above the platform and ignited to form a main sealing plug for the well. In some embodiments an upper plug is formed by igniting an upper thermite reaction charge above the main thermite reaction charge. The upper plug confines the products of ignition of the main thermite reaction charge.
