Abstract: A system and method for controlling an electrical submersible pump (ESP) of a well, including a processor and a non-transitory computer-readable medium storing instructions that when executed by the processor cause the processor to perform operations. The operations include obtaining a well model corresponding to the well, obtaining a target well rate for the well, then receiving, from one or more data sources associated with one or more components of the well, operational data associated with the ESP operating at the target well rate within the well, determining a target efficiency of the ESP at the target well rate based on the well model, and then modifying, based on the operational data and the target efficiency an operating characteristic of the ESP.

Abstract: A method of automated preventive and predictive maintenance for downhole valves in a well system includes receiving, at a plurality of first times, first diagnostics data of the plurality of downhole valves, where each downhole valve is at a respective first valve position at a respective first time, and the diagnostics data represents a valve condition of each downhole valve at a respective valve position and at a respective time. The method also includes receiving, at a plurality of second times, second diagnostics data of the plurality of downhole valves, where each downhole valve has been moved from the respective first valve position at the respective first time to a respective second valve position at a respective second time. The first diagnostics data and the second diagnostics data are compared. Based on results of comparing, a valve maintenance operation is selected for each downhole valve.

Abstract: A process for determining the productivity index of a multilateral completion using data from individual laterals and data from commingled well tests is disclosed. The process includes 1) determining the productivity index for each single lateral by iteratively altering the productivity index until the individual lateral flowrate based on a known reservoir pressure is matched and 2) further determining the productivity index by iteratively altering the productivity index until the commingled flowrate is matched. The productivity index may be used to set wellhead pressures and inline control valve (ICV) settings for production.
