A method and apparatus for performing an operation in a wellbore penetrating the earth's formation. The apparatus includes a string and a first processor. The string is disposed in the wellbore. The first processor determines, by using a first friction test at a first friction test time, a first friction parameter between a first selected subregion and the wellbore and a second friction parameter between a second selected subregion and the wellbore.

System to model distributed torque, drag and friction along a string

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.

Autonomous torque and drag monitoring

Examples of techniques for model-based parameter and state estimation for directional drilling in a wellbore operation are provided. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes receiving, by a processing device, measurement data from the wellbore operation. The method further includes performing, by the processing device, an online estimation of at least one of a parameter to generate an estimated parameter and a state to generate an estimated state, the online estimation based at least in part on the measurement data. The method further includes generating, by the processing device, a control input to control an aspect in the wellbore operation based at least in part on the at least one of the estimated parameter and the estimated state. The method further includes executing a control action based on the control input to control the aspect of the wellbore operation.

Model-based parameter estimation for directional drilling in wellbore operations

A method of facilitating a drilling operation includes: receiving a current set point for a drilling operation, the current set point indicating a value of an operational parameter at which the drilling operation is being performed; receiving a global limit indicating at least one of a maximum and a minimum value of the operational parameter that is permitted to be applied for the drilling operation; defining a local limit for the operational parameter, the local limit indicating at least one of a local maximum value and a local minimum value of the operational parameter; receiving a parameter change value, the parameter change value indicating a proposed change to the operational parameter from the current set point; and selecting a level of automation by which the operational parameter can be adjusted, the level of automation based on a comparison of the parameter change value and the local limit.
