1. An injection well in a hydrocarbon reservoir comprising:
steam injection tubing having steam splitters spaced apart along the length of the tubing, each of the steam splitters having a plurality of steam outlets for directing steam into the hydrocarbon reservoir, wherein a number of the plurality of the steam outlets is selected for operation for each of the steam splitters, the number varying between the steam splitters, the number for each of the steam splitters being selected based on a target flow of steam and location of each of the steam splitters along the length of the hydrocarbon reservoir, wherein the target flow of steam is determined based on hydrocarbon reservoir properties in sections of the reservoir, the sections of the reservoir each associated with at least one of the steam splitters.
