Abstract
System and methods for optimizing flow distribution across multiple production zones are provided. A flow distribution is assigned to a plurality of production zones along a wellbore within a formation. A temperature value is estimated for each of the production zones, based on the assigned flow distribution. The estimated temperature value is compared with an actual temperature value determined for each production zone. An error amount for the estimated temperature value is calculated based on the comparison. Based on the error amount, it is determined whether or not the flow distribution has reached a global optimum. The assigning, the estimating, the comparing, the calculating, and the determining are repeated until it is determined that the flow distribution assigned to the plurality of production zones has reached the global optimum.
