## Narrative

It is believed that the hole was initiated when the temperature inside the hole exceeded 225 degrees.  The heat may have been created by a chemical reaction caused by pyrites inside of the wet hole that would have created sulfuric acid which started a catalytic reaction.  The reaction would have been intensified with the addition of the oxidizing agent contained in the emulsion.
