... water holdup (Yw). How to accurately obtain the value of water holdup (Yw) from fluid capacitance log is a key question in the production log interpretation of multi-phase flows. Based on the geometry and principle of the fluid capacitance instrument, a new response equation of fluid capacitance, C, to...

... Abstract Production logging suites often consist of some redundant measurements. For example, water holdup in wells producing oil and water is commonly measured by both fluid density and fluid capacitance logs. Each of these logs will contain some error, the level of which is likely different...
