Patent number: 11098541Abstract: A PDC drill bit for use in downhole air drilling includes a body with a face for engaging a bottom of a hole being drilled and a gauge for engaging a side of the hole being drilled. The face includes a cone, a nose outward of the cone, a shoulder outward of the nose. The bit further includes channels formed in the face of the bit that extend from within the cone to the gauge. The channels define a plurality of blades separated by the channels. Each of the plurality of blades has a leading edge with PDC cutters mounted thereon. One or more of the channels are defined by two side walls and a bottom wall and has a length, width and depth. The width or depth remains substantially constant from a first point on its length within the cone to a second point within the shoulder.Type: GrantFiled: September 28, 2018Date of Patent: August 24, 2021Assignee: Ulterra Drilling Technologies, L.P.Inventors: Christopher M. Casad, Ben Chrest, Thomas A. Damian, Carl Aron Deen, Kristy Everheart, Kerry Sisson

Patent number: 11015394Abstract: A drag bit includes a blade extending from the bit body and supporting inner cutters proximate the longitudinal axis and outer cutters spaced from the longitudinal axis. The inner cutters are rotationally offset from the outer cutters. During operation the inner cutters deposit cut material in a channel that is contiguous with a channel that receives material cut by the outer cutters. The cutters and the contiguous channels flush agglomerating material from the slots.Type: GrantFiled: August 17, 2018Date of Patent: May 25, 2021Assignee: Ulterra Drilling Technologies, LPInventors: Christopher M. Casad, Carl Aron Deen

Patent number: 10724323Abstract: A downhole tool for cyclically generating cyclical pressure waves in drilling fluids of sufficient magnitude to vibrate a drill string or coiled tubing to reduce friction between drill string or coiled tubing and a wall of an uncased or cased wellbore. A passageway through which drilling fluid flows through the tool is constricted to increase pressure of the drilling fluid while it continues to flow through the tool. A bypass around the constriction is cyclically opened by a rotary valve to increase the flow area through the tool for the drilling fluid while at the same time an axially shifting valve, shifted by a pair of rotating cams, opens to allow drilling fluid to vent to an annulus formed by the drill string or coiled tubing and a wall of the wellbore.Type: GrantFiled: August 17, 2018Date of Patent: July 28, 2020Assignee: Ulterra Drilling Technologies, L.P.Inventors: Matthew B. Roseman, Christopher M. Casad, Thomas A. Damian, Jason C. Maw
