Multilateral wells are a new evolution of horizontal wells in which several wellbore branches radiate from the main borehole. Multilateral wells placement problem consists of finding the best well locations and trajectories for multilateral wells in a hydrocarbon reservoir to boost the later productivity and recovery. The problem of placing multilateral wells can be subjugated by the number of wells capped, length of the wells, and cost threshold to place multilateral wells in part or in whole.  

This technology introduces a novel method for multilateral wells placement in hydrocarbon reservoirs utilizing transshipment network optimization approach. Using this method generates multiple numbers of wells with different designs honoring the optimum completion points in a reservoir. Also, new algorithm associated with this technology was developed to find optimum location and trajectories for multilateral wells in local and global terms followed by the utilization of a partitioning algorithm to reduce the computational cost of the optimization process. The proposed method will not only create different multilateral designs, it will justify the trajectories of every section generated.
