Abstract: A trip speed table is created containing records. Each record contains a step location, wherein a step is defined to be the location in a well of a deepest end of a drill string, a minimum trip speed for the step location, wherein the minimum trip speed is defined to be the maximum trip speed less than or equal to a default trip speed at which the drill string can be tripped without exceeding a fracture gradient or falling below a pore pressure at a slice depth, and the slice depth where the minimum trip speed for the step location occurred.

Abstract: Certain aspects and features relate to a system that efficiently determines optimal actuator set points to satisfy an objective in controlling equipment such as systems for drilling, production, completion or other operations associated with oil or gas production from a wellbore. A platform can receive data and also make use of and communicate with multiple algorithms asynchronously and efficiently to project automatic optimum set points for controllable parameters. Services can provide data over a real-time messaging bus and the data can be captured by an orchestrator that aggregates all data and calls a solver orchestrator to determine optimized parameters for a current state in time to send to control systems or display in a dashboard.
