Systems and methods for evaluating formations having unknown or mixed salinity |
摘要 |
Formation fluid salinity is an important parameter in water saturation and formation porosity measurements. Systems and methods are disclosed herein to provide accurate water saturation and/or formation porosity measurements in the presence of unknown or highly variable salinity levels. Some logging tool assembly embodiments include a resistivity tool and an augmented neutron porosity tool. The neutron porosity tool is augmented with a gamma ray detector configured to measure the rate at which hydrogen nuclei capture neutrons from a neutron source. A processing system coupled to the logging tool assembly provides a salt compensated formation porosity log and/or a water saturation log. The logging tool assembly can also include a density logging tool and a natural gamma ray logging tool to provide a salt independent triple-combo log.
