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.
Claims14
A method for evaluating a fluid produced from a formation in an oil field, comprising:
- determining whether the fluid comprises water or a hydrocarbon with a measurement of a water sensor on a production logging tool;
- determining a chloride content of the fluid with a measurement of a chloride sensor on the production logging tool;
- and
- based on a level of the chloride content, determining whether the fluid is water naturally occurring in the formation or an injection fluid.

A production logging tool for evaluating a fluid produced from a formation in an oil field, comprising:
- a water sensor that obtains a downhole water measurement;
- a chloride sensor that obtains a downhole chloride measurement;
- and
- a processor that receives the downhole water measurement and determines whether the fluid is water or a hydrocarbon from the downhole water measurement, that receives the downhole chloride measurement and determines a chloride content of the fluid from the downhole chloride measurements, and based on a level of the chloride content of the fluid, determines whether the fluid is naturally occurring in the formation or an injection fluid.
