Abstract

Systems and methods for a multi-finger caliper (MFC) tool are provided. A method for an MFC tool on a digital slickline (DSL) in a well at a wellsite includes: collecting MFC raw data from a plurality of fingers of an MFC tool while downhole, processing the MFC raw data, the processing including: determining values for each of the plurality of fingers of the MFC tool from the MFC raw data over time, generating calibrated data by applying a calibration to the MFC raw data and to the processed determined values, and extracting key information from the calibrated data and values for each finger of the MFC tool the key information including a calibrated minimum, maximum, and average radius values for all fingers together, sorting the extracted key information, including generating a log of the key information, and electronically transmitting the log on the DSL to a surface of the wellsite.

Dependent claims

A method for a multi-finger caliper (MFC) tool on a digital slickline (DSL) in a well at a wellsite, comprising:

collecting MFC raw data from a plurality of fingers of an MFC tool while the MFC tool is downhole in a well;
processing the MFC raw data, the processing comprising:
determining at least one of:
respective last-received data, a minimum radius value, a maximum radius value, and an average radius value for each of the plurality of fingers of the MFC tool from the MFC raw data over a predefined period of time;
generating calibrated data by applying a calibration to the MFC raw data and to the determined at least one of:
respective last-received data, minimum radius value, maximum radius value, and average radius value;
and
extracting key information from the calibrated data and values for each of the plurality of fingers of the MFC tool the key information comprising a calibrated minimum radius value, a calibrated maximum radius value, and a calibrated average radius value for all of the plurality of fingers together over the predefined time period;
sorting the extracted key information, the sorting comprising generating a log of the key information;
and
electronically transmitting the log on the DSL to a surface of the wellsite.

A system for a multi-finger caliper (MFC) tool on a digital slickline (DSL) in a well at a wellsite, comprising:

one or more processors;
and
a non-transitory computer-readable medium storing instructions that, when executed, cause the one or more processors to:
collecting MFC raw data from a plurality of fingers of an MFC tool while the MFC tool is downhole in a well;
process the MFC raw data, the processing comprising:
determining at least one of:
respective last-received data, a minimum radius value, a maximum radius value, and an average radius value for each of the plurality of fingers of the MFC tool from the MFC raw data over a predefined period of time;
generating calibrated data by applying a calibration to the MFC raw data and to the determined at least one of:
respective last-received data, minimum radius value, maximum radius value, and average radius value;
and
extracting key information from the calibrated data and values for each of the plurality of fingers of the MFC tool the key information comprising a calibrated minimum radius value, a calibrated maximum radius value, and a calibrated average radius value for all of the plurality of fingers together over the predefined time period;
sort the extracted key information, the sorting comprising generating a log of the key information;
and
electronically transmit the log on the DSL to a surface of the wellsite.
