Abstract: A rotational alignment system determines the angular relationship between two or more elements of a drill string using one or more sensors that detect one or more reference objects positioned on the drill string. A control unit determines the rotational or angular offset between two or more elements on the drill string using measurements made by the sensor(s). In one application, rotational offset values are used by a surface logging computer to correlate sensor data provided by a logging tool.

Abstract: A method and system is presented which provides a TDM framework for managing self-describing measurement data. The TDM framework provides applications with a central platform for accessing measurement data across an entire enterprise system. By means of individual plug-ins, which may be specific to a given data file format, meta-data for each data store in the enterprise may be indexed in a unified manner. The unified indexing, in turn, provides the ability to browse and query the indexed measurement data without requiring the opening or reading from a source data file.
