Abstract: A disclosed method for gas lift rate management 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 selecting well production rates and adjusting gas lift rates. The method also includes storing the gas lift rates determined for the solution for use with gas lift operations of the production system. A disclosed gas lift rate management system includes a memory having a gas lift rate management module and one or more processors coupled to the memory. The gas lift rate management module, when executed, causes the one or more processors to: perform a production system simulation based on a fluid model and a fully-coupled set of equations; expedite convergence of a solution for the production system simulation by selecting well production rates and adjusting gas lift rates; and store the gas lift rates determined for the solution for use with gas lift operations of 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.
