Abstract
A composition and method for breaking down and denaturing friction-reducing compound introduced into the ground during the drilling of gas and oil wells and for destroying other contaminants and biohazards naturally present within and artificially introduced into hydrocarbon wells, which are formed as a result of the drilling and pumping processes. The composition includes several species of oxidizing agent compounds that are effective in breaking down hydrogen sulfide produced by bacteria as well as the friction-reducing polymer used during drilling and several other organic compounds.
Claims7
A method for denaturing and breaking down a friction-reducing polymer introduced into gas and oil wells during the drilling and pumping process, said method comprising the following steps:
- adding to a fracture fluid an oxidizing agent, selected from one of the following:
- an oxy-chloro compound;
- and
- an earth metal alkali oxidizing compound;
- wherein said fracture fluid contains a friction-reducing polymer as one ingredient;
- and
- introducing the fracture fluid and oxidizing agent concurrently and simultaneously downhole into a gas or oil well during a hydraulic fracturing process used to extract gas or oil from subterranean formations;
- wherein the oxidizing agent initially denatures or unwinds the polymer.
