A method includes obtaining a reservoir model for a subsurface reservoir, identifying a current state of the subsurface reservoir using the reservoir model, and a computer processor selecting an optimization function from multiple optimization functions according to the current state of the reservoir to obtain a selected optimization function. The method further includes the computer processor calculating valve positions of physical devices using the selected optimization function. The valve positions are implemented.

Method and system for reactively defining valve settings

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.

Flow balancing for a well

Methods and systems for performing well network production optimizations are described. For example, in one embodiment, a method of allocating an applied resource throughout a well network includes receiving topological data into an analytical model of a well network having one or more wells. The topological data includes a plurality of performance curves that relate well performance to one or more levels of an applied resource. The method also includes determining an optimum allocation of the applied resource using the analytical model to maximize an operating parameter of the well network, including converting a portion the analytical model having one or more wells and a linear inequality relationship to a modified portion having a single variable and a linear equality constraint.

Methods and systems for performing oilfield production operations

An integrated model based on plural underlying models relating to corresponding aspects of subterranean formation development is provided. A utility is created to perform a function using the integrated model. The utility is assigned to execute in a distributed computing system having a plurality of computer node. Computations performed by the utility are distributed across the plurality of computer nodes, where the computations are related to simulations using the integrated model.

Executing a utility in a distributed computing system based on an integrated model

A method is disclosed for optimal lift resource allocation, which includes optimally allocating lift resource under a total lift resource constraint or a total production constraint, the allocating step including distributing lift resource among all lifted wells in a network so as to maximize a liquid/oil rate at a sink.
