    Abstract: Using a reservoir simulator, a reservoir model state is obtained. The reservoir model state is used to trace streamlines to obtain streamline trajectories and detect fluid fronts along the streamlines. Using the streamline trajectories, the streamlines are connected to wells. The streamlines are grouped for multiple granularity levels, into groups to obtain a grouping hierarchy. Through the granularity levels of the grouping hierarchy, fluid front time of flights are determined for the groups, and target flowrates assigned to completion devices based on the fluid front time of flights to obtain target flow rates. A completion design is presented that incorporates the target flowrates.

    Abstract: Flow balancing includes selecting, for each down hole flow control valve of a well, a transformed well performance curve corresponding to a first down hole flow control valve pressure to obtain transformed well performance curves. The well includes a lateral including the down hole flow control valves. Using a constraint set that includes a balancing condition for the lateral, a network optimization analysis is performed on the transformed well performance curves to generate a set of choke positions corresponding to each down hole flow control valve. Network modeling of the well is performed based on the set of choke positions to obtain a second down hole flow control valve pressure for each down hole flow control valve. Using the set of choke positions, a field operation is performed for the well based on the second down hole flow control valve pressure being within a threshold difference of the first down hole flow control valve pressure for each down hole flow control valve.

    Abstract translation: 流量平衡包括为井的每个井下流量控制阀选择对应于第一井下流量控制阀压力的变换油井性能曲线以获得转化井性能曲线。 井包括包括井下流量控制阀的侧面。 使用包括横向的平衡条件的约束集合，对变换的井性能曲线进行网络优化分析，以产生对应于每个井下流量控制阀的一组扼流圈位置。 基于扼流器位置的集合进行井的网络建模，以获得每个井下流量控制阀的第二井下流量控制阀压力。 使用该组阻塞位置，基于第二井下流量控制阀压力在每个向下流量控制阀的第一井下流量控制阀压力的阈值差内，对井进行现场操作。

    Abstract: A physical pipeline network is decomposed into multiple subnetworks. The subnetworks include upstream subnetworks and at least one downstream subnetwork. A network solver is executed on the upstream subnetworks in parallel to obtain a set of boundary conditions and a set of control device settings. The set of boundary conditions and a set of control device settings are then used to execute the network solver on the downstream subnetwork and obtain a result having another set of control device settings. The network solver may repeat executions until convergence is achieved. When convergence is achieved, the result is presented.
