    Abstract: Systems and methods of the present disclosure provide systems and methods for receiving one or more sets of parameters related to an operation corresponding to a wellbore. At a first time, the operation is simulated using the one or more sets of parameters and at least one simulator. Pertinent results from the simulation are recorded and stored in a table. The pertinent results include at least one constraint. At a second time, the constraint is retrieved from the table for performance of the operation, and the constraint is used to control the operation.

    Abstract: Systems and methods of the present disclosure include receiving measured data corresponding to a wellbore and locating the measured data in a flow map corresponding to the wellbore. The method also includes converting the measured data to determine friction loss and comparing the located measured data and the determined friction loss. Moreover, the method also includes determining that the located measured data is consistent with the determined friction loss with a common flow regime and deeming the common flow regime as a current flow regime. Furthermore, the method includes controlling an operation in the wellbore based at least in part on the deemed current flow regime.

    Abstract: A method, computer program product, and computing system are provided for defining one or more injector completions and one or more producer completions in one or more reservoir models. One or more edges between the one or more injector completions and the one or more producer completions in the one or more reservoir models may be defined. The one or more edges between the one or more injector completions and the one or more producer completions may define a graph network representative of the one or more reservoir models. The one or more reservoir models may be simulated along the one or more edges between the one or more injector completions and the one or more producer completions.

    Abstract: Managing oilfield operations include obtaining a subsurface model including a fracture design model having an fracture property with an uncertain value. A set of representative values that represent uncertainty in the fracture property is obtained and used to solve an oilfield optimization problem with a control variable to obtain a solution. The solution includes an optimal value for the control variable. Based on the solution, an oilfield design is generated and stored.

    Abstract: Methods and systems are provided for controlling gas lift in at least one production well, which determine a quadratic function that relates flow rate or value of oil produced from a production well to gas flow rate for gas injected into the production well based on flow rate measurements for gas injected into the production well and corresponding flow rate measurements of oil produced from the production well. The quadratic function is used to determine an optimal flow rate for gas injected into the production well. The optimal flow rate for gas injected into the production well is used to control the flow rate of gas injected into the production well, and an oil flow rate produced from the production well is measured at the optimal gas flow rate for iterative processing to refine the quadratic function and determination of optimal gas flow rate if need be.
