1. A method of completing an injection well drilled through a heterogeneous reservoir comprising a plurality of intervals containing varying amounts of recoverable oil, the method comprising:
determining a volume of recoverable oil in each of the intervals along the injection well;
determining a target steam flow for each of the intervals configured to facilitate recovery of the volume of recoverable oil from each of the intervals;
selecting steam tubing for deployment in the injection well, the steam tubing comprising steam flow control devices spaced apart along the steam tubing, each of the steam flow control devices configured to support at least one steam outlet;
determining locations of the steam flow control devices in relation to the intervals for when the steam tubing is deployed in the injection well;
calculating a number and size of the at least one steam outlet for each of the steam flow control devices utilizing hydraulic pipe flow calculations for delivery of the target steam flow determined for each of the intervals;
supporting the at least one steam outlet of the calculated number and size on each of the steam flow control devices; and
deploying the steam tubing having the determined number and size of the at least one steam outlet at each of the steam flow control devices for delivery of the target steam flow to each of the intervals.
