  • Determination of wellbore condition
    Patent number: 11078760
    Abstract: Pullout information for a drilling tool may be obtained. The pullout information may characterize one or more operating characteristics of the drilling tool during pullout of the drilling tool from the wellbore. A pullout friction factor for the wellbore may be determined based on the pullout information. A comparison of the pullout friction factor to a pullout friction factor threshold may be performed to determine whether the pullout friction factor satisfies or violates the pullout friction factor threshold. The condition of the wellbore to run the casing into the wellbore may be determined based on whether the pullout friction factor satisfies or violates the pullout friction factor threshold.
    Type: Grant
