Abstract

Examples described herein provide a computer-implemented method that includes modeling at least one torque and drag parameter for an upstream well construction operation. The method further includes acquiring at least one measured torque and drag parameter during performing the upstream well construction operation. The method further includes interpolating friction factors at different sampling times for the at least one measured torque and drag parameter. The method further includes transposing the friction factors at the different sampling times for the at least one measured torque and drag parameter to a time-based series. The method further includes performing a corrective action responsive to determining that one or more of the friction factors at a particular point in time is indicative of the one or more of the friction factors deviating from an expected value.
