    Abstract: A disclosed vibration monitoring method includes: processing sensor information downhole to detect one or more vibration modes; responsively updating a vibration mode state machine; communicating a current machine state to an uphole module; deriving from said current machine state at least a primary vibration mode and associated severity; and modifying at least one drilling parameter if the severity exceeds a threshold. A disclosed drilling system implementation includes: a drill string; a rig or other deployment device that conveys the drill string into a borehole using at least one controllable drilling parameter; one or more downhole sensors providing vibration-related signals; a downhole processor that operates on the vibration-related signals to detect one or more vibration modes and responsively updates a vibration mode state machine; and an uphole module that receives the current state from the downhole processor and derives from the current state at least a primary vibration mode and severity.

    Abstract: A directional drilling system includes a housing and a motor positioned within the housing and operably coupled to a drill bit to rotate the drill bit. The system further includes a primary pad assembly comprising a primary pad and a primary actuator coupled to the primary pad to selectively extend from an exterior of the housing, and a backup pad assembly to back up the primary pad assembly, the backup pad assembly comprising a backup pad and a backup actuator coupled to the backup pad to selectively extend from the exterior of the housing.

    Abstract: A method and apparatus for real-time analysis of wellsite inventory activity is described. The method includes logging receipt of inventory items at a wellsite and tracking their use. In certain embodiments, the inventory may be chemical sacks mixed into drilling fluids, and their use may be tracked with an RFID scanner near the threshold of a mixing hopper. The tracking information may be used to update an inventory management database. When an item is used, real-time wellsite data may be analyzed to determine its impact on drilling performance. The efficacy of the item may thereby be determined and stored in a predictive model database. In making future wellsite drilling decisions, the predictive model database may be used to select cost-efficient performance improvement solutions. Additionally, performance information may be used to correct real-time data measured during future uses of the inventory item. Reports may be produced from the collected information, including billing reports, regulatory reports, and end-of-well reports. Information collected from various wells may assist during planning for future well-sites, including assessing inventory needs, developing a logistical plan, and bidding on projects.
