For maximizing well stimulation profitability, unsteady-state flow pressure-transient analysis methods yield more accurate predictions of productivity increases than do steady-state methods.
This technique appears to be superior in representing actual field conditions.
In designing stimulation treatments to improve production capacity of a well, the oil and gas industry traditionally uses empirically derived graphs based on steady-state flow. These graphs usually relate increased productivity with all well damage removed. Thus, the final skin-effect value...
