    Abstract: Embodiments of the subject technology provide for receiving real-time drilling data comprising different drilling parameters measured during a drilling operation. The subject technology calculates a kick detection parameter based at least in part on the different drilling parameters. The subject technology detects an occurrence of a kick during the drilling operation when the kick detection parameter deviates from a trend formed by previously calculated kick detection parameters. Further, the subject technology activates an alarm during the drilling operation in response to detected occurrence of the kick to facilitate preventing a blowout.

    Abstract: A method of controlling drill bit trajectory in a subterranean formation includes receiving drilling parameters for operating a specific bottomhole assembly (BHA), constructing, with a computer processor, a directional drill-ahead simulator including a computer model of the BHA and the subterranean formation, calculating axial motion and lateral motion of a drill bit connected to a bottom end of the BHA using formation parameters and drilling parameters, predicting bit walk of the drill bit by accounting for and calculating contact forces and frictional forces between the BHA and a wall of a borehole in the subterranean formation using the computer model of the BHA, and determining an adjusted drill bit traj ectory to account for the predicted bit walk. The method includes determining adjusted drilling parameters for operating the BHA to substantially follow the adjusted drill bit trajectory and operating the BHA according to the adjusted drilling parameters.

    Abstract: Tools are often leased or rented by the owners of the tools. The price paid to rent or lease the tools can be based on a number of factors including the total time in which the downhole tool is in use, the time in possession of the renter, number of times the tool goes in and out of the well, or other factors. To accurately estimate the price owed to the owner of the tool by the renter of the tool, monitoring apparatuses equipped with usage trackers can be utilized to quantitatively measure time usage, possession usage or other basis from which a fee is to be calculated. The quantitative measurements taken by the usage tracker may be used to determine for example, the amount of time a tool is used or possessed to allow fee calculations, or simply to determine usage time for maintenance purposes.

    Abstract: A well advisor system and console for monitoring and managing well drilling and production operations. The system may be accessed through one or more workstations, or other computing devices, which may be located at a well site or remotely. The system is in communication with and receives input from various sensors. It collects real-time sensor data sampled during operations at the well site. The system processes the data, and provides nearly instantaneous numerical and visual feedback through a variety of graphical user interfaces ("GUIs"), which are presented in the form of an operation-specific console. The input and data provides information related to rate of penetration concerning a well being drilled, and present the information for related parameters in real time against a plotted "fairway" of determined maximum and minimum values, with a focus on the safety of the drilling operation.
