  • Prevention of backflow during drilling and completion operations
    Patent number: 11131146
    Abstract: A system includes a drill bit, and a tubular connected thereto. The tubular is configured to be rotated to rotate the drill bit and drill a length of a borehole and cemented in place. The tubular and the drill bit form a conduit to permit cement to be pumped through the tubular and the drill bit and into an annulus. The system also includes a collar disposed between the tubular and the drill bit. The collar includes a receptacle made from a drillable material, which has a profile that corresponds to a shape of a component deployed through the length of the tubular, and is configured to form a substantially fluid tight seal between the component and the drillable material when the component is seated in the receptacle. The collar and the component prevent backflow of the cement.
