Abstract: Embodiments of the present invention provide a machine, program product, and computer-implemented method to select a fit-for-purpose tool for reservoir saturation monitoring. A computer stores a plurality of characteristics for a plurality of well-logging tools, including open hole and closed hole resistivity, pulse-neutron spectral carbon-oxygen, and pulse-neutron capture technologies, as well as a predetermined ranking of tools within a technology. The computer obtains user inputs associated with conditions of a candidate well, e.g., a minimum tubing restriction, whether the wellbore is open or cased, and whether the well is a wet producer. Inputs can also include an objective of the reservoir saturation monitoring, such as, evaluating sweep efficiency or identifying remaining pay for sidetrack or perforation.
