Publication number: 20260103950Abstract: A drilling rig apparatus includes first and second industrial handling robots, a catwalk, and a powered mousehole collectively configured for automated red zone tubular handling. One of the industrial handling robots is secured to the drilling rig floor while the other is mounted on a track that allows movement out of the way of manual tubular operations, optionally off the drilling rig floor. The catwalk lifts each tubular from a staging area into position for grasping by the track-mounted industrial handling robot, with an orientation closer to vertical than horizontal. The powered mousehole moves tubulars held therein up or down to facilitate assembly with additional tubulars by the industrial handling robots.Type: ApplicationFiled: July 29, 2025Publication date: April 16, 2026Inventors: Ashish Gupta, David Siljeg, Denver Lee, Zachary Gonzales

Patent number: 11572687Abstract: A mast assembly for a drilling rig includes a mast formed from a plurality of mast subunits. The mast assembly includes a lower drilling machine, upper drilling machine, and upper mud assembly, each of which is coupled to and movable vertically relative to the mast. The mast subunits are separable when the mast is in a transport configuration such that the LDM is positioned in a first subunit and the UDM is in a second subunit of the mast when the mast is in the transport configuration. The mast assembly may be used during a continuous drilling operation.Type: GrantFiled: April 22, 2022Date of Patent: February 7, 2023Assignee: NABORS DRILLING TECHNOLOGIES USA, INC.Inventors: Ashish Gupta, Padira Reddy, Denver Lee
