Method of extinguishing oil and gas well fires |
| abstract |
Oil and gas well fires may be extinguished by injecting into such wells below the fire a stable liquid dispersion of a water soluble anionic vinyl addition polymer and a water soluble cationic polymer, and then inverting this liquid dispersion in the well to produce a three-dimensional water and hydrocarbon liquid insoluble gel-like structure which seals off said well; thereby extinguishing said fires. |
