Production Logging Tool Services provide essential data to evaluate both static and dynamic reservoir conditions. Memory logging captures depth-correlated data such as flow rates, pressure, and fluid ratios (gas/oil/water) for well analysis and reservoir simulation. This helps identify issues like gas or water breakthrough, crossflow, and channeling. A range of sensors ensures accurate logging even in challenging conditions, including multiphase and varying flow rates. Available sensors include casing collar locator, gamma ray, temperature, pressure, densitometer, flowmeters, and capacitance for water holdup.
