Claim 0:
1. A method for reservoir fluid production from a well having a wellbore in communication with a formation containing the reservoir fluid, comprising:
injecting fracturing fluid through a string into the formation to create fractures in predetermined zones along the wellbore;
supplying injection fluid to the wellbore via the string;
injecting the injection fluid from the wellbore to the formation through a first set of fractures defined in a first set of zones, while blocking fluid communication between the formation and the wellbore through a second set of fractures defined in a second set of zones;
ceasing the supply of the injection fluid;
blocking fluid communication between the formation and the wellbore through the first set of fractures;
permitting fluid communication between the formation and the wellbore through the second set of fractures to enable reservoir fluid to flow from the formation into the wellbore; and
transporting the reservoir fluid in the wellbore to surface via the string.
