    Abstract: A method of managing a network of wells and surface facilities includes partitioning the network to obtain a pipe sub-network and two or more well sub-networks, and constructing an associated set of equations that represent a steady-state fluid flow in the sub-network. The method further includes setting boundary conditions for each well sub-network, and determining a steady-state flow solution for each well sub-network. The method further includes establishing boundary conditions for the pipe sub-network, and finding a steady-state flow solution for the pipe sub-network. If the solution does not match the estimated pressure, the method further includes adjusting the estimated pressure, repeating said setting, determining, establishing, finding, and adjusting operations until the calculated and estimated pressures converge, and analyzing flow rates of the steady-state flow solutions to evaluate suitability of a modification to the network.

    Abstract: Systems and methods for determining operating settings for a fluid production system that includes wells and a processing facility, the method including identifying at least one swing well and one or more non-swing wells and determining at least one target parameter equation that is a function of at least one processing facility constraint and one or more non-swing well parameters. The method further includes incorporating the target parameter equation into a fully-coupled equation set representing the production system, simulating the production system using the fully-coupled equation set to obtain one or more operating settings that meet the processing facility constraint, and presenting to a user the operating settings.

    Abstract: A disclosed method for a hydrocarbon production system includes collecting production system data. The method also includes performing a simulation based on the collected data, a fluid model, and a fully-coupled set of equations. The method also includes expediting convergence of a solution for the simulation by reducing occurrences of non-physical attributes during the simulation. The method also includes storing control parameters determined for the solution for use with the production system.

    Abstract: Systems and methods for determining operating settings of a fluid production system with a gathering network and a plurality of reservoirs, at least some of which include a method that includes lumping common pseudo-components into reservoir pseudo-components associated with each of the reservoirs. Each common pseudo-component is associated with the gathering network and maps to one reservoir pseudo-component of each of the reservoirs. The method further includes performing at least part of a fully-coupled simulation of the gathering network and the reservoirs using the common pseudo-components to obtain one or more operating settings that meet one or more constraints of the production system, and presenting to a user the operating settings.

    Abstract: A method for determining active constraint equations in a network of wells and surface facilities includes constructing at least one constraint equation for a connection in the network. Each constraint equation includes a respective slack variable and a respective slack variable multiplier. The method further includes constructing a base equation for the connection. The base equation includes the respective slack variable and another respective slack variable multiplier. The method further includes introducing a pseudo slack variable for another connection in the network such that a Schur complement, of a matrix of constraint and base equations dependent only on slack variable multipliers, is sparse. The method further includes solving for each respective slack variable using the Shur complement matrix. The method further includes adjusting a variable parameter of the network using results from solving for each respective slack variable.
