A non-emulsifying agent and its use for the increased recovery of oil from the stimulation of an oil reservoir

Well stimulation processes wherein an aqueous system is introduced into a hydrocarbon bearing underground formation to increase its rate of oil and/or gas production subsequent to the stimulation are improved by the incorporation into said system of a non-emulsifying agent and a cationic organic pol...

Zusammenfassung:Well stimulation processes wherein an aqueous system is introduced into a hydrocarbon bearing underground formation to increase its rate of oil and/or gas production subsequent to the stimulation are improved by the incorporation into said system of a non-emulsifying agent and a cationic organic polymer whereby the formation exposed to said system is water-wet.
