A resonant receiver for electromagnetic telemetry of wellbore-related data can be used to improve signal reception for transmitting or receiving low-amplitude downhole signals that include noise. A system can comprise a surface assembly with an antenna for wirelessly communicating signals with equipment positioned downhole in a wellbore. The surface assembly can comprise an amplifier and a tank circuit operable to resonate at a resonant frequency to pass a received signal at the resonant frequency to the amplifier while also shunting noise outside of the resonant frequency to ground. In some embodiments, a downhole transceiver in wireless communication with the surface assembly can comprise a similar tank circuit and amplifier.

In some embodiments, apparatus and systems, as well as methods, may operate to launch a set of currents into a corresponding set of existing well casings; monitor, in a well under construction, changes in at least one of a magnetic field or an electric field perturbed by the set of currents after each one of the set is launched; and determine a location of the well under construction in relation to the set of existing well casings. In some embodiments, the activities include inducing current into a drillstring located in a well under construction; monitoring, at a set of existing well casings, changes in at least one of a magnetic field or an electric field perturbed by the current after the current is induced; and determining a location of the well under construction in relation to the set of existing well casings. Additional apparatus, systems, and methods are disclosed.

A method for facilitating the navigation of data generated using an analytic application. In particular, a method of creating and using a query chain to access data is described. The user designates some data field as being of particular interest. A list of further query chains for the user to choose from is shown. The user can select one of these query chains to further navigate the database, modify one of the query chains listed, or can create a new query chain by further navigating the database. The selections made by the user while further navigating the database are recorded and linked into a query chain, which can be stored for later use. Accordingly, user access to a field of particular interest is facilitated, and information of particular interest can be accessed in a timely manner.

Value-chained queries in analytic applications

A method and apparatus for transporting data for a data warehousing application. Data is extracted from one or more source containing data having a standard data structure and is translated into data that contains meaningful business terms. The translated data is then stored. In the present embodiment, an analytic business component is operable for extracting data from the source, translating the extracted data and for storing the translated data into a staging area. The translated data is then processed to obtain data having a common structure. In the present embodiment, a source adapter processes the translated data to obtain data having a common structure. The data having a common structure is then transformed into a format suitable for loading into a data mart. In the present embodiment, an analytic data interface receives the data having a common structure and transforms the data for loading into a data warehouse. The data is then stored in a data warehouse.
