First Claim
1. A machine to select a fit-for-purpose tool for reservoir saturation monitoring, the machine comprising:
- a processor positioned to determine a well-logging tool selection responsive to a plurality of characteristics of a well-logging tool for a plurality of well-logging tools from a plurality of vendors and responsive to conditions for a candidate well, the characteristics of a well-logging tool including an outer diameter of the tool and a well-logging technology utilized by the tool;
an input/output interface for receiving and displaying data between the processor and a user; and
a memory having stored therein a computer program product, stored on a tangible and non-transitory computer memory media, operable on the processor, the computer program product comprising a set of instructions that, when executed by the processor, cause the processor to determine a well-logging tool selection by performing the operations of;
storing the plurality of characteristics for the plurality of well-logging tools to thereby enable categorization of the well-logging tools from the plurality of vendors, the categorization being according to the plurality of characteristics,receiving by the processor a first one or more inputs from the user, each of the one or more inputs associated with a condition of a candidate well to thereby avoid irrelevant input gathering,communicating with the user for a second one or more inputs associated with the conditions of the candidate well by the processor through the input/output interface responsive to the first one or more inputs so that additional relevant inputs are received by the processor,comparing by the processor the stored plurality of characteristics for the plurality of well-logging tools to the first and second one or more inputs associated with conditions of the candidate well, anddetermining a well-logging tool selection by the processor responsive to the comparison of the stored plurality of characteristics for the plurality of well-logging tools to the first and second one or more inputs to select a fit-for-purpose tool for reservoir saturation monitoring so that the processor creates for the user a recommendation for reservoir saturation monitoring of the candidate well.

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. The computer compares the characteristics for the well-logging tools to the user inputs and determines a well-logging tool selection responsive to the comparison to thereby recommend a course of action for the candidate well.
