  • Mitigation of frictional heat checking in well casing
    Patent number: 11060390
    Abstract: Downhole casing temperature may be predicated at the drill string/casing interface as a function of side force on the casing due to drill string tension, the speed or rate of penetration of the drill string in the axial direction, the rate of rotation of the drill string, and a calibrated/assumed friction factor. Predicted down hole casing temperature may be used as a proxy to monitor casing integrity.
    Type: Grant
