Abstract: A drill bit includes a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance. The drill but further includes one or more cutting elements mounted to the one or more blades outside of the cone section such that the cone section is void of cutting elements, and a plurality of milling elements secured to the bit body within the cone section.

Abstract: A method of quantifying wear data on a well tool includes scanning a used well tool with a scanner and thereby generating a scanned file of the used well tool, the scanner being in communication with a computer system, aligning the scanned file with an original solid model file of the used well tool and thereby obtaining and displaying an overlay output, wherein the solid model file is stored on the computer system and identifies individual wear parts of the used well tool, creating and placing a digital feature on one or more of the individual wear parts displayed on the overlay output, and calculating deviation between the solid model file and the scanned file at each digital feature of the one or more individual wear parts and thereby determining material removed from the individual wear parts of the used well tool.

Abstract: A drill bit includes a bit body providing a plurality of blades disposed about a centerline of the bit body, one or more primary cutters mounted at a leading face of each blade, and one or more offset cutters mounted to at least one of the plurality of blades and angularly offset from a laterally adjacent primary cutter and the leading face of the at least one of the plurality of blades.

Abstract: A method of quantifying wear data on a well tool includes identifying the well tool based on a solid model file and a data file corresponding to the well tool, wherein the solid model and data files are stored on a computer system and separately identify wear parts of the well tool, scanning the well tool with a scanner and thereby generating a scanned file of the well tool, the scanner being in communication with the computer system, aligning the scanned file with the solid model file to obtain an overlay output, creating digital features on the wear parts of the scanned file, and calculating deviation between the solid model file and the scanned file at the digital features for the wear parts and thereby determining material removed from the wear parts of the well tool.

Abstract: An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated.
