MODIFIED PUSH/PULL FLOOD PROCESS FOR HYDROCARBON RECOVERY (D#78,644-F) ABSTRACT OF THE DISCLOSURE The invention comprises injecting about 5% to about 25% pore volumes of a recovery fluid simultaneously into an underground formation through at least two wells. One well which is destined to be the production well is shut-in for a soak period of about one to about 60 days while injection of the recovery fluid is continued through the second well. The shut-in well is then converted to a production well and hydrocarbons and other fluids are produced from the production well while recovery fluid is injected through the second well. The shut-in well is then converted to a production well and hydrocarbons and other fluids are produced from the production well while recovery fluid is injected through the second well.
