  • Patent number: 10445841
    Abstract: Systems and methods may be used to select a drill bit design for an earth-boring rotary drill bit for use in a particular drilling application. The systems may include a computer server, and a remote device configured to communicate with the computer server through a network. The computer server may include a database including information relating to normalized scores for a plurality of drill bit responses for a plurality of differing drill bit designs. The computer server may receive information from the at least one remote device, to select one or more potential drill bit designs from the at least one database based on the information, and to transmit information relating to the selected one or more potential drill bit designs to the remote device. Such systems may be used in methods of selecting drill bit designs for earth-boring rotary drill bits for use in respective drilling applications.

  • Patent number: 10087683
    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.

  • Patent number: 8297380
    Abstract: Casing shoes comprise a nose portion having an inner profile and an outer profile. At least one cutting structure is on the outer profile. A stem section extends longitudinally from the nose portion. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is disposed within the stem section. Methods of installing sections of casing within wellbores comprise advancing the at least one section of casing into contact with subterranean formation material with a casing shoe attached thereto. At least one of a float valve mechanism, a cementing stage tool, a float collar mechanism, and a landing collar structure is carried within the casing shoe into the wellbore. The wellbore is drilled or reamed using at least one cutting structure on the casing shoe as the at least one section of casing is advanced into the wellbore.
