Well intervention through casing perforation and acid treatment was performed on well SK-2D to improve its productivity. Completion tests indicated stimulation of the mud-damaged payzones, although
initial discharge tests showed that contribution froin the stimulated bottom zone was masking the potential two-phase feed from tlie upper perforated
intervals.
Subsequent series of short-term discharge tests suggest recovery of the two-phase upper payzone and remarkable improvement in the output of the well. Wellbore simulation of SK-2D using flowing temperature-pressure-spinner (TPS) logs and discharge data projects possible optimization of well utilization by controlling the bottom liquid feed zone and maximizing the contribution from the upper two-phase zone.
