Scenario:
You are an engineer monitoring a production well. You have the following data:
Task:
1. The difference between the static and dynamic liquid levels (5000 feet - 4800 feet = 200 feet) indicates that the well is producing and the liquid level is decreasing during production. This is expected as fluids are being extracted from the reservoir. 2. The well's performance is likely not optimal. The dynamic liquid level is 100 feet above the top of the perforated interval (4900 feet). This suggests that only a portion of the perforated interval is actively contributing to production. This could indicate a problem with the completion, a decline in reservoir pressure, or other factors affecting fluid flow. 3. Factors that could affect the dynamic liquid level include: * Production rate: Higher production rates will result in a lower dynamic liquid level. * Reservoir pressure: Decreasing reservoir pressure will cause the dynamic liquid level to drop. * Wellbore completion: Problems with the perforations or completion equipment can affect fluid flow and the dynamic liquid level. * Fluid properties: Changes in fluid properties, such as viscosity or density, can impact the dynamic liquid level. * Other factors: Issues like water or gas coning can also influence the dynamic liquid level.
