Abstract
Disclosed are a production logging tool and method for evaluating fluid produced from a formation of an oilfield. The fluid is measured by a water sensor to determine if the fluid is water, and a chloride sensor to determine chloride levels of the fluid. Based on the chloride levels of the fluid, it can be determined whether the fluid is naturally occurring water, or if the fluid is an injection fluid.
