The Effect of Regular and Long Cyclic Steam Stimulation Method on Oil Production Performance in X Field

Cyclic Steam Stimulation (CSS) is the process of a single production well which is consisted of three phases: injection phase, soaking phase and the production phase. The purpose of this analysis is to see the effect of cyclic jobs on temperature, oil production and pump damage that occurs after regular and long cyclic jobs. The analysis was performed by looking at the historical data of production, the reservoir temperature history data and the pump production job data for all the wells in the X field. Based on the production analysis, 53.24% production wells in the X field  are already at the ramp down stage and 46.75% are already at the ramp up stage. Based on the analysis of the reservoir temperature, it was known that 3rd to 4th months are the majority of the Heat Endurance Time (HET) for the regular cyclic stimulation and 5th-6th months are the majority of the HET for long cyclic stimulation in X field. Based on the pump job data, there are only three wells were damaged. It showed the cyclic stimulation is really safe to be performed in this field.
