Determining viable hydraulic fracture scenarios. At least some of the illustrative embodiments include: executing a fracture planning program, and determining a set of schedules from the fracture planning program, each schedule comprising a volume of fracture fluid, amount of proppant, and flow rate of the fracture fluid; providing each schedule of the set of schedules to a stress analysis program, executing the stress analysis program, and determining a set of indications from the stress analysis program, each indication indicative of whether a respect schedule exceeds engineering limits of a tubing string; and providing at least some of the schedules to a fracture simulation program, executing the fracture simulation program, and determining a set of fracture geometries from the fracture simulation program, each fracture geometry corresponding to a respective schedule.
