Power loss dysfunction characterization

A system for determining real-time dysfunctions by measuring power-loss of signal propagation, the system comprising:

• a mid-string drilling sub sensor associated with a first well drill string in a first wellbore in a first well for acquiring a first time series;
• a sensor associated with the first well drill string for acquiring a second time series, the sensor positioned on a surface of the earth;
• a bottom hole assembly associated with the first well drill string to provide data to determine a geometry of the first wellbore;
• and
• a computer comprising a memory, a processor, and one or more programs stored via the memory that, when executed by the processor, cause the computer to:
• determine a first model parameter, a second model parameter, and a third model parameter that characterize the first wellbore using the first time series, the second time series and the geometry of the first wellbore by deriving a power loss of signal propagation, and
• mitigate a drilling dysfunction while drilling another well, the drilling dysfunction determined using at least the first model parameter and the second model parameter.

A drilling rig apparatus for drilling multiple wells, the apparatus comprising:

• a drill rig with a first drill string for drilling a first well;
• a mid-string drilling sub sensor associated with the first drill string for acquiring a first time series;
• a second sensor associated with the first drill string, the second sensor positioned at a surface of the earth, the second sensor for acquiring a second time series;
• a bottom hole assembly associated with the first drill string to provide data to determine a geometry of a wellbore;
• and
• a computer comprising a memory, a processor, and one or more programs stored via the memory that, when executed by the processor, cause the computer to:
• determine a first model parameter, a second model parameter, and a third model parameter using the first time series, the second time series, and the geometry of the wellbore, the first model parameter, the second model parameter, and the third model parameter characterizing a power loss of signal propagation for a signal travelling through the first drill string, and
• mitigate a drilling dysfunction while drilling another well, the drilling dysfunction determined using at least the first model parameter and the second model parameter.
