The disclosure presents processes and methods for decomposing friction factors and generating a calibrated friction factor and adjusted input parameters. The calibrated friction factor and adjusted input parameters can be utilized by a borehole system as an input to adjust borehole operations to improve the operational efficiency. The friction factors can be decomposed by type, such as geometrical, geomechanical, mechanical, and fluid. The disclosure also presents processes and methods for identifying an outlier portion of a friction factor, as identified by a deviation threshold that can be used to identify adjustments to borehole operations in that portion of the borehole. A system is disclosed that is capable of implementing the processes and methods in a borehole operation system, such as a downhole system, a surface system, or a distant system, for example, a data center, cloud environment, lab, corporate office, or other location.

A system to improve calibration of geophone and hydrophone pairs is described. The system generates first and second phase shifted data by applying a first and second phase shift to first seismic data acquired by the geophone. The system generates a first upgoing wavefield by summing the first phase shifted data and second seismic data acquired by the hydrophone, and a second upgoing wavefield by summing the second phase shifted data and the second seismic data. The system generates a first downgoing wavefield from a difference of the first phase shifted data and the second seismic data, and a second downgoing wavefield from a difference of the second phase shifted data and the second seismic data. The system determines ratios of the upgoing wavefields and the downgoing wavefields for each phase shift to identify the highest ratio, and selects the phase shift corresponding to the highest ratio for calibration.
