Abstract: Systems, methods, and computer-readable media for forecasting a time to complete a simulation of a reservoir simulation model. A processor can run a simulation of a reservoir simulation model for a first predetermined period of time associated with a first computation step of the simulation. The processor can measure a performance result of the simulation for the first predetermined period of time. The performance result can include an elapsed wall clock time and a timespan simulated. The processor can then forecast a remaining time to complete the simulation of the reservoir simulation model based on the performance result.

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.
