Calculating energy based net pressure and corresponding discharge area observed during hydraulic stimulation processes

A system for use in hydraulic stimulation operations comprising:

• an information handling system comprising:
• at least one memory operable to store computer-executable instructions;
• at least one communications interface to access the at least one memory;
• and
• at least one processor configured to access the at least one memory via the at least one communications interface and execute the computer-executable instructions to:
• obtain one or more treatment data inputs from a well system;
• and
• determine a discharge area by applying the one or more treatment data inputs to a function that determines discharge area in terms of volumetric flow rate of the fracturing fluid, wherein the discharge area is a total area of all downhole exits through which the fracturing fluid exits a wellbore into a subterranean formation.
