Abstract: For some embodiments, a software application for correcting sensor data in a remote database (114, 118) according to magnetic correction parameters obtained from a geophysical survey service, the sensor data obtained from directional instruments on a well tool (107, 108, 110). The remote database resides in a field computer (112) at a well site, and a copy of the remote database may also reside in a real time operations computer system. For some embodiments, the sensor data for particular depths and measurement times are stored as rows in a table (FIG. 3). The correction software may write new rows in the remote database with the corrected sensor data, or may write new rows in a second database for storing corrected sensor data (FIG. 1).

Abstract: A method and system to render a graphic display that includes a color-coded risk indicator to facilitate the steering of a drill string during subterranean drilling. The system comprises a receiver to receive measurement data from downhole instrumentation forming part of the drill string during the drilling of a well bore in a geological formation, and an exit risk determining module to determine an exit risk value based at least in part on the measurement data. The exit risk value is indicative of a risk of exiting of the formation by the drill string. A display module is provided to render the graphic display of decision information, to assist steering of the drill string. The color-coded exit risk indicator comprises a colored area having a color indicative of the exit risk value, the color of the colored area being changeable in response to changes in the exit risk value.

Abstract: A method and apparatus for managing networks across multiple domains are disclosed. For example, the method stores a mapping table that correlates one or more Customer Edge Routers (CERs) with one or more Route Processing Modules (RPMs) in at least one seed-file distributor, where each of the one or more Customer Edge Routers (CERs) is monitored by one of the at least one availability manager. The method receives an alarm associated with one of the one or more RPMs that affects one of the one or more CERs, where the alarm is received by one of the at least one availability manager that is monitoring the affected one of the one or more CERs. The method then provides a status associated with the one of said one or more RPMs in accordance with the alarm.

Abstract: A destination local area network (LAN) and a local LAN are coupled by an ATM-based wide area network (WAN). Each LAN includes a router. The WAN includes at least two ATM switches having switch ports. In order to identify and map a connection between the destination LAN and the local LAN, an end-to-end LAN-WAN-LAN connection components template is created. The template contains a number of fields which are populated during the course of identifying the connection. The connection is identified by using IP addresses, subnet masks and virtual circuit identifier values of ATM interfaces on the routers. Virtual circuit identifier values associated with pairs of IP addresses in the connection are identified, and associated with identifier values from the ATM interfaces on the routers. The associated configuration information and components of the WAN are retrieved and stored alongside entries in the list.

Abstract: A destination local area network (LAN) and a local LAN are coupled by an FR-ATM Service Interworking (SIW)-based wide area network (WAN). In order to identify a connection between the destination LAN and the local LAN, an end-to-end LAN-WAN-LAN connection components template is created, which contains a number of fields which are populated during the course of identifying the connection. FR and ATM interfaces are identified on each router. The network addresses conform to Internet Protocol (IP) and are part of the same subnet. The IP address, IP subnet mask, city, state, DLCI value retrieved from the FR interface, and the VPI/VCI values retrieved from the ATM interface are stored to create a list describing the physical and logical characteristics of the FR and ATM interfaces. A pair of network addresses is identified using the IP address in conjunction with the subnet mask stored on either the FR or ATM interface in the list. The DLCI value associated with each of the network IP addresses is identified.

Abstract: A method, apparatus, and computer program product for mapping a connection between a destination local area network (LAN) and a local LAN where the LANs are coupled by a frame relay wide area network (WAN). The method includes the steps of identifying a local network address for each frame relay interface in the local LAN; obtaining the destination data link connection identifier (DLCI) associated with each local network address; deriving the destination network address associated with each destination interface; and obtaining the local DLCI associated with each destination network address. The method can also include the step of deriving WAN switch ports associated with the connection using the local and destination DLCIs.
