Expert system for selecting fit-for-purpose technologies and wells for reservoir saturation monitoring

A computer program product, stored on a tangible and non-transitory computer memory media, operable on a computer, the computer program product comprising a set of instructions that, when executed by the computer, cause the computer to determine a well-logging tool selection by performing the operations of:

• storing in a database in tangible and non-transitory computer memory media a plurality of characteristics of a well-logging tool for a plurality of well-logging tools from a plurality of vendors, the characteristics of a well-logging tool including an outer diameter of the tool and a well-logging technology utilized by the tool, to thereby enable categorization of the well-logging tools from the plurality of vendors, the categorization being according to the plurality of characteristics;
• obtaining from a user a plurality of inputs associated with conditions of a candidate well so that the computer can select amongst the plurality of well-logging tools according to the categorization of the well-logging tools responsively to the conditions of the candidate well;
• comparing the stored plurality of characteristics for the plurality of well-logging tools to the plurality of inputs associated with conditions of the candidate well;
• and
• determining a well-logging tool selection responsive to the comparison of the stored plurality of characteristics for the plurality of well-logging tools to the plurality of inputs associated with conditions of the candidate well to select a fit-for-purpose tool for reservoir saturation monitoring so that the computer creates for the user a recommendation for reservoir saturation monitoring of the candidate well.

A computer-implemented method to select a fit-for-purpose tool for reservoir saturation monitoring, the computer-implemented method comprising:

• storing by a computer in a database in tangible and non-transitory computer memory a plurality of characteristics of a well-logging tool for a plurality of well-logging tools from a plurality of vendors, the characteristics of a well-logging tool including an outer diameter of the tool and a well-logging technology utilized by the tool, to thereby enable categorization of the well-logging tools from the plurality of vendors, the categorization being according to the plurality of characteristics;
• obtaining from a user by the computer in a first computer process a plurality of inputs associated with conditions of a candidate well so that the computer can select amongst the plurality of well-logging tools according to the categorization of the well-logging tools responsively to the conditions of the candidate well;
• comparing by the computer in a second computer process the stored plurality of characteristics for the plurality of well-logging tools to the plurality of inputs associated with conditions of the candidate well from the first computer process;
• and
• determining a well-logging tool selection by the computer responsive to the comparison of the stored plurality of characteristics for the plurality of well-logging tools to the plurality of inputs associated with conditions of the candidate well from the first computer process to select a fit-for-purpose tool for reservoir saturation monitoring so that the computer creates for the user a recommendation for reservoir saturation monitoring of the candidate well.
