| Abstract | The cycling effect is an impact that shows that the minimum pressure required by a well to remain stable in production is not achieved. The root cause of the cycling effect in a well is the presence of multiple feed zones which have difference pressure, enthalpy and permeability. This root cause can be concluded from data acquisition such as a PTS Shut-In survey and down-hole sampling. In the case of Well EPT-L/1, the cycling effect causes the well to not produce. It will always experience a pressure drop if produced with a minimum pressure of 8 barg in conditions of up to 60% throttling and when the pressure is less than 8 barg, the pressure in Well EPT-L/1 will slowly reduce. Thus, the operational pressure to produce the well should be a minimum of 8 barg. |
