Claim:
1. A system for producing fluids from a subterranean hydrocarbon reservoir comprising: an injection well and a production well that traverse the hydrocarbon reservoir, wherein the injection well includes an injector segment that is completed with at least one slotted liner and the production well includes a producer segment that is completed with at least one slotted liner, wherein the injector segment of the injection well is positioned in the hydrocarbon reservoir above and generally parallel to the producer segment of the production well, wherein the injector segment of the injection well is logically partitioned into a plurality of sections and the producer segment of the production well is logically partitioned into a plurality of sections that correspond by relative location to the sections of the injector segment to define a plurality of injector-producer section pairs; a plurality of injection tubing strings for the sections of the injector segment, wherein each injection tubing string is configured to supply stimulating fluid to an associated section of the injector segment where the stimulating fluid flows into the at least one slotted liner of the injector segment and exits through the at least one slotted liner into the hydrocarbon reservoir in the vicinity of the injector segment of the injection well; a plurality of surface-located control devices that control head pressure of stimulating fluid flowing through the respective injector tubing strings in order to regulate the flow of stimulating fluid flowing through the injection tubing strings; a plurality of production tubing strings for the sections of the producer segment, wherein each production tubing string is configured to carry fluids produced from an associated section of the producer segment of the production well; and a plurality of controllers for the injector-producer section pairs, wherein each controller is configured to control at least one process variable for 2 value associated with the at least one process variable of the corresponding injector-producer section pair over time, wherein the error value is used in a control function processed by the given controller, wherein the control function is configured to minimize the error value over time by adjusting, a control variable over time, and wherein the adjusted control variable is used to control the surface-located control device for the injector tubing string that supplies stimulating fluid to the injector section of the associated injector-producer section pair.
