1. A method comprising:
receiving diagnostics data of a hydraulic fracturing completion of a wellbore;
mapping fracturing events associated with the hydraulic fracturing completion to additive control parameter values of the diagnostics data;
accessing a fracture formation model that models formation characteristics of fractures formed through the wellbore into a formation surrounding the wellbore during the hydraulic fracturing completion with respect to surface variables of the hydraulic fracturing completion that include a fluid pressure variable;
training the fracture formation model based on:
the additive control parameter values of the diagnostic data being mapped to the fracturing events, and
the surface variables that include the fluid pressure variable;
selecting one or more subsurface objective functions from a plurality of subsurface objective functions for changing one or more of the formation characteristics of the fractures, the one or more subsurface objective functions including an objective function for cluster efficiency and at least one other subsurface objective function;
assigning a weight to the objective function for cluster efficiency that is different than a weight assigned to the at least one other subsurface objective function; and
initiating operation of a first completion plan for performing the hydraulic fracturing completion of the wellbore;
applying the trained fracture formation model based on the diagnostics data and the weight assigned to the objective function for cluster efficiency that is different than the weight assigned to the at least one other subsurface objective function to determine values of the surface variables for controlling the formation characteristics of the fractures to converge;
identifying based on environmental data and an event of the mapped fracturing events that a second completion plan for performing the hydraulic fracturing completion should be initiated; and
initiating the second completion plan based on the environmental data and the event of the mapped fracturing events.
