20130092447 | Downhole Tool Impact Dissipating Tool - An impact dissipation tool for supporting a downhole tool in downhole applications. The tool includes a base and a housing. The tool also includes a carriage located within the housing and coupled to the base, the carriage being movable relative to the housing upon a predetermined impact force. A dissipator disposed inside the housing is collapsible due to the relative movement of the carriage and the housing. The collapse of the dissipator dissipates the impact force transferred to the downhole tool. | 04-18-2013 |
20130014934 | Smart Drop-Off Tool and Hang-Off Tool for a Logging StringAANM Macrae; JonathanAACI HoustonAAST TXAACO USAAGP Macrae; Jonathan Houston TX USAANM Finci; BulentAACI Sugar LandAAST TXAACO USAAGP Finci; Bulent Sugar Land TX US - A hang-off tool for supporting a tool inside a tubular member includes a logging string configured to generate logging data, a computing system coupled to the logging string and configured to communicate the logging data to another tool, and a radially expandable member having a retracted position and an expanded position. The radially expandable member is configured to engage a radially-increased profile of an inner surface of the tubular member in the expanded position to support the hang-off tool. The radially expandable member is also configured not to engage the radially-increased profile in the retracted position. | 01-17-2013 |
20120205116 | Flapper Valve - A flapper valve includes a valve body, a valve cover pivotally coupled to the valve body at a hinge between an open and closed position, and a biasing element biasing the valve cover to the closed position. The valve cover includes an interior face comprising a sealing surface and a boss including a face surrounded by a beveled edge joining the boss with the sealing surface. | 08-16-2012 |
20110315445 | Methods for Installling Sensors in a Borehole - A method of installing a sensor in a borehole drilled through underground formations, wherein the borehole is drilled with a hollow drill string formed from a series of pipe sections connected end-to-end, a drill bit being positioned at one end of the drill string and having an closure that is operable to provide an opening between the borehole and the inside of the drill string, the method comprising:

20110120774 | Drill Bit and Method for Inserting, Expanding, Collapsing, and Retrieving Drill Bit - A drill bit comprising a bit body connectable to a drill string at an first end, which bit body is provided with a longitudinal passageway extending from an opening at the first end to a port at a second end a closure element for closing the passageway, when the closure element is in a closing position, which closure element is removable, and wherein the closure element comprises a first and a second member which are movable relative to each other between an expanded configuration and a collapsed configuration, in which collapsed configuration, the closure element is retractable through the passageway to the first end. | 05-26-2011 |
20110011579 | Apparatus and System to Allow Tool Passage Ahead of a Bit - Drill bits enable the use of tools in a wellbore when it is undesirable or impossible to remove the drill bit. Drill bits include a drill bit insert, a latch assembly, a housing, a running tool, and a shaft trigger to operate the latch assembly. | 01-20-2011 |
