Abstract: Systems and methods of the present disclosure provide for a process that includes receiving, at one or more processors, an indication to send a slug through a wellbore. The process also includes selecting, by the one or more processors, one or more choke templates indicating choke sizes of a choke for the wellbore. Moreover, the process includes controlling, using the one or more processors, the choke to the choke sizes based on the one or more templates as part of a wellbore clean-up process.

Abstract: A method can include receiving a number of samples of liquid production values and associated gas-lift injection rates for one of one or more wells; determining a prospective optimal gas-lift injection rate for the one of the one or more wells via a regression that fits the number of samples; responsive to the prospective optimal gas-lift injection rate satisfying one or more gas-lift injection rate criteria, issuing an instruction to implement the prospective optimal gas-lift injection rate for the one of the one or more wells; receiving a new sample as a measured liquid production value for the implemented prospective optimal gas-lift injection rate and responsive to satisfaction of one or more compliance criteria; and replacing one of the number of samples with the new sample.

Abstract: Systems and methods for optimizing oilfield rig fleet scheduling and deployment are disclosed. Wells are identified to have time constraints by which they are grouped into “ON”, “BY”, and “ADD” categories. ON wells have a beginning drilling availability window; BY wells have an ending drilling availability time only; and ADD wells have no beginning or ending time of drilling availability. The systems and methods optimize scheduling with ON wells having higher priority than BY wells, and BY wells having higher priority than ADD wells.

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.

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: A technique for reducing harmonic vibration in a multiplex multi-pump system. The technique includes establishing a lower bound of system specific vibration-related information such as via pressure variation or other vibration indicator. Establishing the lower bound may be achieved through simulation with the system or through an initial sampling period of pump operation. During this time, random perturbations through a subset of the pumps may be utilized to disrupt timing or phase of the subset. Thus, system vibration may randomly increase or decrease upon each perturbation. Regardless, with a sufficient number of sampled perturbations, the lower bound may be established. Therefore, actual controlled system operations may proceed, again employing random perturbations until operation of the system close to the known lower bound is substantially attained.

Abstract: A method, apparatus, and computer readable storage medium perform oilfield-wide optimization in a field with a plurality of wells, with each well including a well flow rate management mechanism controlled by an associated well controller. In a central controller, a network simulation model functioning as a proxy of the field is accessed to determine an optimal allocation solution for the field, and a well-specific control signal is generated for each of the plurality of wells based upon the determined optimal allocation solution. The well-specific control signal for each of the plurality of wells is communicated to cause the associated well controller to control a flow rate management parameter associated with the well flow rate management mechanism for the well.

Abstract: A method, apparatus, and program product generate a flow control device design for well completions in one or more wells of an oilfield in part by equipping a reservoir simulation model with multiple flow control device proxies represented by one or more generalized expressions for pressure drop including multiple tunable parameters associated with various physical flow control devices. Multiple reservoir simulations are then run using the reservoir simulation model to optimize an objective function based on at least a subset of the tunable parameters such that an optimal set of values determined from the optimization may be used to select flow control device types for the well completions.
