Abstract
This invention relates to the use of silicone-induced hydrocarbon foams as well stimulants, for example as illustrated by their use in fracturing well formations, removal of paraffin in wells, removal of condensate hydrocarbons from blocked gas wells, etc.
Claims5
A process of well stimulation, comprising forcing an organo-polysiloxane-induced hydrocarbon foam mixture suitable for use in well stimulation into said well, said hydrocarbon being selected from the group consisting of kerosene, #2 diesel oil, well formation condensate and xylene, said siloxane having a molecular weight of from about 5,770 to about 20,000 and being of a concentration of from about 0.5 to about 2% by volume in said hydrocarbon and injecting nitrogen into said mixture.
